Streptozotocin (STZ) Chemical Structure

CAS No. 18883-66-4

Streptozotocin (STZ, NSC-85998, Streptozocin, U 9889) is a glucosamine-nitrosourea derivative, which is a DNA-methylating, carcinogenic, antibiotic and diabetes inducing agent. Streptozotocin induces autophagy and apoptosis. Solutions are best fresh-prepared.

  • Effect of telmisartan and other treatments on (a) nitric oxide, (b) serum cortisol level. Data is expressed as mean ± SEM (n = 6). Statistical significances were determined using one way ANOVA followed by dunnetts post hoc test. ###p < 0.001 as compared with normal, *p < 0.05, *p < 0.01, ***p < 0.001 as compared to STZ control. TMS: telmisartan, MET: metformin, FLX: fluoxetine. The figure in parenthesis indicates the dose in mg/kg po.

Biological Activity

Description Streptozotocin (STZ, NSC-85998, Streptozocin, U 9889) is a glucosamine-nitrosourea derivative, which is a DNA-methylating, carcinogenic, antibiotic and diabetes inducing agent. Streptozotocin induces autophagy and apoptosis. Solutions are best fresh-prepared.
In vitro

Streptozotocin directly methylates DNA and is highly genotoxic, producing DNA strand breaks, alkali-labile sites, unscheduled DNA synthesis, DNA adducts, chromosomal aberrations, micronuclei, sister chromatid exchanges, and cell death. Free radicals are involved in the production of DNA and chromosome damage by Streptozotocin. [1] Streptozotocin is toxic to pancreatic beta cell. Exposed to 15 mM Streptozotocin for 1 hr followed by a 24 hrs recovery period induces apoptosis in murine pancreatic beta cell line, INS-1. Streptozotocin (30 mM) causes the cells to undergo necrosis (22%) as well as apoptosis (17%). [2]

In vivo Streptozotocin is often used to induce diabetes mellitus in experimental animals. Streptozotocin is selectively accumulated in pancreatic beta cells via the low-affinity GLUT 2 glucose transporter. Streptozotocin (60 mg/kg) injection for 4 month induces rapid degranulation of beta cells without necrosis, development of cataracts and accumulation of glycogen in the proximal convoluted tubules of the kidney. Streptozotocin (100 mg/kg) produces lesions in the exocrine cells of the pancreas, and persistence of small, possibly secretory, granules in the Golgi zone of beta cells in rats of ‘Streptozotocin diabetes’. [3] Streptozotocin is found to be carcinogenic in rats, mice and hamster. A single administration of Streptozotocin is able to induce tumors in kidney, liver, lung, pancreas, uterine and liver tumors in hamster. Intraperitoneally injected with Streptozotocin (100-150 mg/kg) for normotensive Wistar Kyoto rats (WKY) for 12 months induces carcinogenesis with tumors incidence of 70% in liver, 20% in kidney and 10% in liver and kidney.

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
