스트레프토조토신 화학적 특성, 용도, 생산

• 개요

  Streptozotocin (STZ) was originally identified in the late 1950s as an antibiotic and was discovered in a strain of the soil microbe Streptomyces achromogenes. In the mid-1960s, STZ was found to be selectively toxic to the beta cells of the pancreatic islets and thus it is used in animal model of diabetes and as a medical treatment for cancers of the beta cells. STZ’s use in cancer chemotherapy received Food and Drug Administration approval in July 1982 and the drug was subsequently marketed as Zanosar.

• 화학적 성질

  off-white to pale yellow crystalline powder

• 용도

  Streptozotocin is used in the treatment metastatic cancer of the pancreatic islet cells. Streptozotocin has a highlrisk of toxicity and is generally limited to cancers that are inoperable.

• 정의

  ChEBI: An antibiotic that is produced by Streptomyces achromogenes. It is used as an antineoplastic agent and to induce diabetes in experimental animals.

• Indications

  Streptozocin (Zanosar), a water-soluble nitrosourea produced by the fungus Streptomyces achromogenes, acts through methylation of nucleic acids and proteins. In addition, it produces rapid and severe depletion of the pyridine nucleotides nicotinamide adenine dinucleotide (NAD) and its reduced form (NADH) in liver and pancreatic islets.
  Streptozocin is not well absorbed from the gastrointestinal tract and must be administered intravenously or intraarterially. In preclinical studies, the plasma half-life was 5 to 10 minutes.
  Streptozocin produces remission in 50 to 60% of patients with islet cell carcinomas of the pancreas. It is also useful in malignant carcinoid tumors.
  Almost all patients have nausea and vomiting. The major toxicity is renal tubular damage, which may be severe in 5 to 10% of patients taking streptozocin. Treatment of metastatic insulinomas may result in the release of insulin from the tumor and subsequent hypoglycemic coma. Less severe toxicities include diarrhea, anemia, and mild alterations in glucose tolerance or liver function tests.

• 일반 설명

  Off-white powder. Melting point 115°C. Used as an anti-cancer drug. Carcinogenic.

• 공기와 물의 반응

  Water soluble.

• 반응 프로필

  [D-GLUCOSE, 2-DEOXY-2-[[(METHYLNITROSOAMINO)-CARBONYL]AMINO] is weakly basic. Reacts exothermically with acids. Reacts with both strong oxidizing agents and strong reducing agents.

• 생물학적 활성

  Antibiotic and antitumor agent. Alkylates DNA and induces diabetes mellitus via reduction of nicotinamide adenine dinucleotide in pancreatic β -cells in vivo .

• Clinical Use

  The glucopyranose moiety of streptozocin confers both islet cell specificity and high water solubility to this nitrosourea-based antineoplastic. As a result, it is used exclusively in metastatic islet cell carcinoma of the pancreas and is administered IV in D5W or normal saline.

• 부작용

  Lacking the 2-chloroethyl substituent of carmustine and lomustine, it is much less reactive as a DNA alkylating agent, and myelotoxicity is relatively rare but not unknown. Cumulative, dose-related renal toxicity can be severe or fatal, however, and 67% of patients receiving this drug will exhibit some kidney-related pathology.

• Safety Profile

  Confirmed carcinogen with experimental carcinogenic, neoplas tigenic, tumorigenic, and teratogenic data. Experimental poison by intravenous, parenteral, subcutaneous, and intraperitoneal routes. Moderately toxic to humans by intravenous route. Human systemic effects: nausea or vomiting, impaired liver function, kidney changes. Human mutation data reported. Experimental reproductive effects. When heated to decomposition it emits toxic fumes of NOx. See also NITROSAMINES.

• Carcinogenicity

  Streptozotocin is reasonably anticipated to be a human carcinogenbased on sufficient evidence of carcinogenicity from studies in experimental animals.

• 환경귀착

  STZ is an odorless ivory-colored crystalline powder or pale yellow crystals. Having the solubility of 5070 mg l^-1 in water at 25 °C, STZ is soluble in alcohol and ketones and slightly soluble in polar organic solvents and insoluble in nonpolar organic solvents. STZ is produced by the soil microorganism and therefore isolated from soil samples that assumed a source of release to the environment. Vapor pressure and Henry’s law constant of STZ are 1.74E-12 mm Hg and 1.08E-10 cm3 per molecule-sec at 25 °C, respectively. No information is currently available for partition behavior in water, sediment, and soil; environmental persistency, long-range transport, or bioaccumulation/ biomagnification.

• Purification Methods

  Recrystallise streptozotocin from 95% EtOH. It is soluble in H2O, MeOH and Me2CO. It has UV max at 228nm ( 6360) in EtOH. The tetraacetate has m 111-114o(dec), and [] D 25 +41o (c 0.78, 95% EtOH) after recrystallisation from EtOAc. [Herr et al. J Am Chem Soc 89 4808 1967, NMR: Wiley et al. J Org Chem 44 9 1979.] It is a potent methylating agent for DNA [Bennett & Pegg Cancer Res 41 2786 1981].
