Barbara J. Rider, in xPharm: The Comprehensive Pharmacology Reference, 2007, Mark G. Papich DVM, MS, DACVCP, in Saunders Handbook of Veterinary Drugs (Fourth Edition), 2016. The present investigation was designed to re-examine whether SH-compounds would affect the diabetogenic action of STZ. It may be injected once a day for 5 days in row every 6 … Streptozocin comes as a powder to be mixed with liquid and given intravenously (into a vein) by a doctor or nurse in a medical facility. 50 (6): 537–46. The present study was undertaken to clarify the mechanism of the diabetogenic activity of streptozotocin. Some studies have reported a correcting of hyperglycemia within 4 weeks of the STZ injection into pigs and thus careful attention is required to make sure spontaneous recovery is not affecting the study outcome (Dufrane et al., 2006). Although it is very effective in primates, pigs show a reduced response to STZ due to a low GLUT2 expression (Dufrane et al., 2006). The development of renal injury is more severe in SHR compared to normotensive (WKY) rats, and urine albumin excretion has been shown to be threefold higher in diabetic SHR (149 ± 1 mg/24 h) compared with control SHR (49 ± 1 mg/24 h) at 32 weeks post-STZ administration (Davis et al., 2003). Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis 1995 , 326 (2) , 227-234. The reconstituted solution is stable for 2 days at room temperature, but should be discarded after 8 hours. Mechanism. Carmustine is a nitrosourea that alkylates nucleic acids. Due to its high toxicity to beta cells, in scientific research, streptozotocin has also been long used for inducing insulitis and diabetes on experimental animals. In the mid-1960s, streptozotocin was found to be selectively toxic to the beta cells of the pancreatic islets, the cells that normally regulate blood glucose levels by producing the hormone insulin. Although its mechanism of action is not completely clear, streptozocin is known to inhibit DNA synthesis, interfere with biochemical reactions of NAD and NADH, and inhibit some enzymes involved in gluconeogenesis. Cancer cells no longer have the normal checks and … - Mechanism of Action & Protocol. No adverse effect was observed (Schapira 1984). Streptozotocin is approved by the U.S. Food and Drug Administration (FDA) for treating metastatic cancer of the pancreatic islet cells. Streptozotocin (STZ), an antibiotic and anticancer agent, is the most prominent diabetogenic chemical agent in diabetes research due to its cytotoxicity in pancreatic beta-cells. [4] Streptozotocin is similar enough to glucose to be transported into the cell by the glucose transport protein GLUT2, but is not recognized by the other glucose transporters. Studies have suggested that STZ is preferably absorbed by insulin-secreting β -cells and induces cytotoxicity by producing reactive oxygen species/reactive nitrogen species (ROS/RNS). 5. Streptozotocin is a DNA, though other mechanisms may also contribute. The cytotoxic action of both these diabetogenic agents is mediated by reactive oxygen species, however, the source of their generation is different in the case of alloxan and streptozotocin. In the presence of intracellular thiols, especially glutathione, … Mechanisms underlying cytotoxicity by the monofunctional nitrosourea streptozotocin were evaluated in DNA repair-deficient E coli mutants. Zahraa Mohammed-Ali, ... Jeffrey G. Dickhout, in Animal Models for the Study of Human Disease (Second Edition), 2017. Streptozotocin : uses, mechanism of action and side effects Gauther, Elizabeth L Nova Biomedical 2014 On the other hand, it is known that alloxan-induced diabetes may be partially prevented by the administration of glutathione and cysteine, which are without effect on streptozotocin (STZ) -induced diabetes. Mechanism of Action . 3) Konrad et al. The selective toxicity of … The drug was subsequently marketed as Zanosar. Alloxan and streptozotocin are widely used to induce experimental diabetes in animals. (2001), The potential mechanism of the diabetogenic action of streptozotocin inhibition of pancreatic beta-cell O-GlcNAc-selective N-acetyl-beta-D-glucosaminidase; Biochem. Inbred strains of mice have been reported to exhibit varying susceptibilities to diabetes induced by low-dose STZ and an order has been identified: DBA/2 > C57BL/6 > MRL/MP > 129/SvEv > BALB/c (Gurley et al., 2006). Oral intake of metformin decreased the plasma glucose of STZ-induced diabetic rats with a parallel increase of plasma β-endorphin–like immunoreactivity (BER). Alloxan and streptozotocin are toxic glucose analogues that preferentially accumulate in pancreatic beta cells via the GLUT2 glucose transporter. Szkudelski T. The mechanism of alloxan and streptozotocin action in B cells of the rat pancreas. Corinna Weber-Schöndorfer, Christof Schaefer, in Drugs During Pregnancy and Lactation (Second Edition), 2007. Streptozocin is unique in its special affinity for the islet cells of the pancreas. However, it becomes difficult to interpret results from this model as one has to distinguish the effects of STZ-induced hyperglycemia from the changes induced by UNX and each of their relative contributions to renal injury. 5. It can produce diabetes mellitus in normal animals, but it is used primarily for treating insuloma tumors in animals. STZ, originally identified as an antibiotic, is an analog of N-acetylglucosamine, which is transported into pancreatic β-cells by GLUT-2 and causes β-cell toxicity, resulting in insulin deficiency (Tesch and Allen, 2007). Physiol Res. STZ is usually administered intraperitoneally in mice and intravenously (IV) in rats (Tesch and Allen, 2007). It is a nitrosourea alkylating agent with selective uptake into pancreatic beta cells because of similarity to glucose in structure. However at high doses, STZ has been shown to cause acute kidney damage in animals due to its non-specific cytotoxicity.

The mechanism of alloxan and streptozotocin action in B cells of the rat pancreas: T. Szkudelski; Physiol. Thus streptozotocin has the potential to be developed as an anti-virulence agent against S. aureus infections. The moderate-to-high dose model was designed to overcome the resistance of certain mouse strains to STZ-induced injury. It is a β-cell-specific toxin that induces irreversible damage to pancreatic islets through free radical generation and DNA damage.122 Besides, nitroso-containing STZ also releases nitric oxide that causes apoptosis.123 It was shown that pretreatment with resveratrol protected pancreatic islets from STZ action through inhibition of caspase-3 and PARP.112 However, other studies reported that administration of resveratrol increases insulin secretion in normal rats 115 but not in STZ-diabetic rats.124 Likewise, in a human trial, despite the improved blood glucose profile, it was thought that the effect was due to improved insulin sensitivity but not β-cell function, as assessed by the HOMAβ index.71 Dietary intake of genistein also significantly improved hyperglycemia and blood insulin levels in STZ-diabetic mice, concomitant with improved islet β-cell proliferation, survival and mass.64 Similar observations were found in the alloxan-induced diabetic rat, where high-dose genistein decreased β-cell loss and improved insulin secretion.125 Other polyphenols, quercetin126 and curcumin,127 also protected pancreatic islets from degeneration by STZ, thus preserving a higher insulin level compared to control. One normal infant who had been exposed to this drug during early pregnancy was reported by Schardein (2000). DNA damage induces activation of PARP which is likely more important for diabetes induction than the DNA damage itself. [11] In the 1960s and 1970s, the National Cancer Institute investigated streptozotocin's use in cancer chemotherapy. As to the mechanisms of diabetogenesis, the glu- cose moiety of the a-anomer is believed to act as a carrier for the ~~itroso-~-methyl-urea portion. Mechanism of action. With all types of STZ-induced diabetes, 1 week after STZ administration, rodents are assessed for hyperglycemia and those with fasting blood glucose over 15 mmol/L (280 mg/dL), which is generally the majority of them, should be included in studies of DN (Tesch and Allen, 2007). Upjohn filed for patent protection for the drug in August 1958 and U.S. Patent 3,027,300 was granted in March 1962. 50, 536-546 (2001). It is used as an antineoplastic agent and to induce diabetes in experimental animals. Streptozotocin is similar enough to glucose to be transported into the cell by the glucose transport protein GLUT2, but is not recognized by the other glucose transporters. ... pp. Physiol Res 50 (6): 537–46. Occasionally it has been used as a cytotoxic agent for treating other tumors in humans (e.g., lymphoma, sarcomas), but these uses are not reported for animals. Together they form a unique fingerprint. Streptozocin acts as an alkylating agent which damages DNA by adding methyl and other alkyl groups which interfere with normal base pairing. 7-14; Frei, B., Molecular and biological mechanism of antioxidant action (1999) The FASEB Journal, 13, pp. STZ can be used in large animals to deplete beta cells and has primarily been used in pigs (Hara et al., 2008) and primates (Koulmanda et al., 2003). In another murine model of blood infection, MRSA (S. aureus USA300) was administered via retro-orbital route and 2.5 mg/kg single daily dose of streptozotocin was started intraperitoneally post 1 h of infection and followed for 2 weeks. Streptozocin is a naturally occurring anticancer antibiotic that has a mechanism of action similar to that of nitrosoureas. Streptozotocin or streptozocin (INN, USP) (STZ) is a naturally occurring alkylating antineoplastic agent that is particularly toxic to the insulin-producing beta cells of the pancreas in mammals. Because of its diabetogenic effect in animals (Tuch 1993), concern was raised about human use of the drug. 3) Konrad et al. The STZ model in both mice and rats is sometimes performed following a UNX to accelerate the progression of renal injury (Tesch and Allen, 2007). Increasing the STZ dose can lead to renal and hepatic toxicity and thus in pigs a narrow therapeutic window makes effective beta cell ablation difficult to achieve. Streptozotocin-induced chromosomal aberrations, SCEs and mutations in CHO-9 parental cells and in EM-C11 mutant cell line. Strains not proficient in recombinational repair which lack either RecA protein or RecBC gene products were highly sensitive to streptozotocin … In a recent study, streptozotocin demonstrated activity against S. aureus by inhibiting the SaeRS two-component system (TCS) responsible for transcriptional regulation of different virulence factors of S. aureus, including adhesins, toxins, and enzymes [7].

Streptozotocin-induced chromosomal aberrations, SCEs and mutations in CHO-9 parental cells and in EM-C11 mutant cell line. The mechanism of alloxan and streptozotocin action in B cells of the rat pancreas Physiol.Res. Streptozotocin is a pancreatic beta-cell-specific cytotoxin and is widely used to induce experimental type 1 diabetes in rodent models. The utilization of Streptozotocin showed significant protective effect on a survival of mice after 2 weeks when compared to control group (P < .0001) [118]. Streptozotocin hoặc streptozocin (INN, USP) (STZ) là một chất chống ung thư kiềm hóa tự nhiên đặc biệt độc hại đối với các tế bào beta sản xuất insulin của tuyến tụy ở động vật có vú. It is one of the most emetogenic agents and requires adequate premedication with antiemetics. In summary, an induction of diabetes with streptozotocin resulted in significant increases in GLUT-4 phosphorylation. Streptozotocin is an antimicrobial agent and has also been used as a chemotherapeutic alkylating agent . antagonise streptozotocin action. This explains its relative toxicity to beta cells, since these cells have relatively high levels of GLUT2.[5][6]. Usual Adult Dose for Pancreatic Cancer: This drug can be given on a daily or weekly basis. Solution Reconstituted, Intravenous: Zanosar: 1 g (1 ea) Streptozocin is a potent DNA-methylating antibiotic. Both effects can be attributed to its specific … Benny Kwong Huat Tan, Khang Wei Ong, in Polyphenols in Human Health and Disease, 2014. It has a role as an … Streptozotocin is an ivory colored crystalline powder with a melting point of 115° C. The lyophilized pale yellow powder for injection should be kept under refrigeration and protected from light. 2008;51(2):216–226. One study showed that rhesus monkeys administered low dose STZ showed both hyperglycemia and autoantibodies to insulin, which is a valuable tool for preclinical testing (Wei et al., 2011). Streptozotocin causes methylation of liver and kidney and pancreatic DNA, but no methylation in brain DNA. mechanisms of action and clinical potential of MF extracts. Diabetes and its related complications remain to be a major clinical problem. Excipient information presented when available (limited, particularly for generics); consult specific product labeling. Potentially fatal renal toxicity and hepatotoxicity have occurred. Vascular hypertension that occurs alters renal hemodynamics and causes GBM thickening along with inflammation and fibrosis (Allen et al., 1997). These data suggest that PM GLUT-4 from diabetic rats is unable to interact with PSPase or that its phosphorylation sites are not accessible to PSPase action. STZ inhibits synthesis of DNA in microorganisms and mammalian cells by alkylation and cross-linking the strands of DNA, and also affecting all stages of mammalian cell cycle. Medical definition of streptozotocin: a broad-spectrum antibiotic C8H15N3O7 with antineoplastic and diabetogenic properties that has been isolated from a bacterium of the genus Streptomyces (S. … Streptozocin is an N-nitrosourea that is an antibiotic produced by Streptomyces achromogenes. Diabetes mellitus was associated with significant (p < 0.01) time course reductions in body weight, plasma insulin and the number o … Streptozocin (also known as streptozotocin) is an agent with specific effects on pancreatic beta cells. Streptozotocin is very soluble in water, lower alcohols and ketones. It is used in medicine for treating certain cancers of the islets of Langerhans and used in medical research to produce an animal model for hyperglycemia and Alzheimer's in a large dose, as well as type 2 diabetes or type 1 diabetes with multiple low doses. It is also an antibiotic effective against Gram-negative bacteria. (2001), The potential mechanism of the diabetogenic action of streptozotocin inhibition of pancreatic beta-cell O-GlcNAc-selective N-acetyl-beta-D-glucosaminidase; Biochem. "Normal" cells stop dividing when they come into contact with like cells, a mechanism known as contact inhibition. Streptozotocin: mechanism of action Streptozotocin (Fig. In the rat models of STZ-induced diabetes, male rats at 8 weeks of age (200–250 g) are starved for 16 h and injected once into the tail vein with STZ (SD = 55 mg/kg, WKY = 60 mg/kg, SHR = 45 mg/kg) in sodium citrate buffer (1 mL/kg) (Cooper et al., 1988; Ma et al., 2004). A typical dose is 500 mg/m 2 /day by intravenous injection, for 5 days, repeated every 4-6 weeks. Streptozotocin, produced by Streptomyces achromogenes, is an antineoplastic agent approved by US FDA in 1982 for the treatment of metastatic cancers of pancreatic islet of langerhans. 27.2.2 The Mechanisms of Streptozotocin Action STZ is a monofunctional nitrosourea derivative and a member of alkylni-trosoureas, a group of alkylating antineoplastic drugs, which are clinically active against a broad range of tumors.… To better understand the insulin-independent plasma glucose–lowering action of metformin, we used streptozotocin (STZ)-induced diabetic rats to investigate the possible mechanisms. As with other alkylating agents in the nitrosourea class, it is toxic to cells by causing damage to the DNA, though other mechanisms may also contribute.DNA damage induces activation of PARP which is likely more important for diabetes induction than the DNA damage itself. Limited reports of efficacy have appeared in the literature, although transient normoglycemia occurred in the experience of these authors.147 The drug is dosed at 500 mg/m2 as an IV infusion with diuresis to avoid renal toxicity, similar to the protocol for cisplatin. It contains a nitrosourea group linked to a methyl group and a glucosamine … This aspect also makes it difficult to differentiate between the direct toxic effect of STZ and lesions caused by hyperglycemia (Breyer et al., 2005). Streptozotocin is a glucosamine-nitrosourea compound. streptozocin: [ strep″to-zo´sin ] an antitumor antibiotic derived from Streptomyces achromogenes , now produced synthetically. Streptozocin is a naturally occurring anticancer antibiotic that has a mechanism of action similar to that of nitrosoureas. Some investigators have combined a partial pancreatectomy with a reduced STZ dose in pigs (Wise et al., 1985). Streptozotocin (2-deoxy-2-(3-methyl-3-nitrosoureido)-d-glucopyranose), an antibiotic with antineoplastic effects produced by Streptomyces achromogenes bacteria, selectively destroys the β-cells of … Upjohn filed for FDA approval of streptozotocin as a treatment for pancreatic islet cell cancer in November 1976, and approval was granted in July 1982. Streptozocin has a rapid half-life in animals, but metabolites may be active. Streptozotocin induces a reversible, mild nephropathy characterized by proteinuria in 50–70% of patients and decreased creatinine clearance in 20–30% of patients. … Cancerous cells lose this ability. Streptozotocin is approved by the U.S. insulin secretion by insulinomas). 2001;50(6):537–546. Streptozotocin is a chemotherapy drug that is given as a treatment for a rare type of cancer called a carcinoid tumour (neuroendocrine tumour). Streptozocin dosing information. J., 356 Pt 1 31 4) Gao et al. However, it is worthy to note that it has been shown that cynomolgus monkeys administered STZ-developed lymphopenia, which could interfere with interpretation of transplantation studies (Nagaraju et al., 2014). Human fetal pancreatic islet cells appear to be resistant to streptozocin toxicity in comparison to rat fetal islet cells (Tuch 1989). STZ has widely been used to induce diabetes in animals. Streptozotocin is a glucosamine-nitrosourea compound. Streptozotocin or streptozocin (INN, USP) (STZ) is a naturally occurring alkylating antineoplastic agent that is particularly toxic to the insulin-producing beta cells of the pancreas in mammals. This suggested the drug's use as an animal model of diabetes,[9][10] and as a medical treatment for cancers of the beta cells. DAILY SCHEDULE:-Recommended Dose: 500 mg/m2 BSA IV by … “Streptozotocin diabetes” is caused by the specific necrosis of the pancreatic β-cells, and this agent is … Unlike carmustine and lomustine, streptozocin does not readily cross the blood–brain barrier, and it is not strongly myelosuppressive. J., 356 Pt 1 31 4) Gao et al. Another possible mechanism of the diabetogenic action of streptozotocin that results in cell death has been attributed to its ability to act as nitric oxide donor in pancreatic cells [25] which inhibits aconitase activity, leading to DNA al-kylation and damage [26]. The mechanism of their action in B cells of the pancreas has been intensively investigated and now is quite well understood. Alloxan: mechanism of action Alloxan has two distinct pathological effects: it selec-tively inhibits glucose-induced insulin secretion through specific inhibition of glucokinase, the glucose sensor of Fig. Streptozotocin is now long off patent and many generic formulations are available. Karl K. Kwok, ... James N. Gibson, in Pharmacology and Therapeutics for Dentistry (Seventh Edition), 2017. Because pancreatic beta cells have high concentrations of glucose transporter 2 (GLUT2), streptozocin is selectively toxic to these cells. 50, 537 (2001), (Review), Abstract; N-monomethyl-arginine and nicotinamide prevent streptozotocin-induced double strand DNA break formation in pancreatic rat islets : F.J.
