| Distamycin | Distamycin is an anticancer antibiotic with antiviral and antiprotozoal activity. Grades: ≥90%. CAS No. 39389-47-4. |  |
| Distamycin A | It is produced by the strain of Streptomyces distallicus NCIB 8936. It has the activity against gram-positive bacterium, mycobacterium, dermatophyte and Trichophyte. It has inhibitory effects on solid tumors such as Epstein-Barr ascites carcinoma, sarcoma 180, Walker 258, oberling-Guerin osteoma, and also inhibits vaccinosis virus, herpes simplex virus, adenovirus, and mouse hepatitis virus in cell culture. Synonyms: Distamycin; Distamycin-3; stallimycin; Herperetin; DST-A; Estalimicina; Stallimicina; Stallimycinum; 2N-(3,3-aminoiminopropyl)-4-[4-(4-formamido-1-methyl-1H-2-pyrrolylcarboxamido)-1-methyl-1H-2-pyrrolylcarboxamido]-1-methyl-1H-2-pyrrolecarboxamide. Grades: 95%. CAS No. 636-47-5. Molecular formula: C22H27N9O4. Mole weight: 481.51. | |
| 1-Methyl-4-nitro-1H-Imidazole-2-carboxylic Acid | 1-Methyl-4-nitro-1H-Imidazole-2-carboxylic Acid is an intermediate used in the synthesis of imidazole-containing DNA minor groove binding oligopeptides related to the antiviral antibiotic netropsin. It is also used to prepare distamycin derivatives with antitumor activities. Group: Biochemicals. Grades: Highly Purified. CAS No. 109012-24-0. Pack Sizes: 250mg, 500mg. Molecular Formula: C5H5N3O4, Molecular Weight: 171.11. US Biological Life Sciences. |  Worldwide |
| 1-Methyl-4-nitropyrrole-2-carboxylic Acid | 1-Methyl-4-nitropyrrole-2-carboxylic Acid is used in the synthesis of Lexitropsin and distamycin analogs with antimicrobial activities. Group: Biochemicals. Grades: Highly Purified. CAS No. 13138-78-8. Pack Sizes: 250mg, 500mg. Molecular Formula: C6H6N2O4, Molecular Weight: 170.12. US Biological Life Sciences. | Worldwide |
| 4-(Boc-amino)-1-methyl-1H-imidazole-2-carboxylic acid | 4-(Boc-amino)-1-methyl-1H-imidazole-2-carboxylic acid (CAS# 128293-64-1) is used in the synthesis of polyamides containing imidazole and pyrrole amino acids. It is also used to prepare distamycin A analogs as DNA binding agents. Synonyms: BOC-NH(4)-MEIMD-(2)-OH; 1-methyl-4-[(2-methylpropan-2-yl)oxycarbonylamino]imidazole-2-carboxylic acid. Grades: ≥ 98 % (HPLC). CAS No. 128293-64-1. Molecular formula: C10H15N3O4. Mole weight: 241.25. | |
| Brostallicin | Brostallicin, a-bromo-acrylamido tetra-pyrrole derivative, is a second-generation minor groove binder (MGB) structurally related to distamycin A with potential antineoplastic activity. Compared with that of other minor groove binders, this agent appears to bind covalently to DNA in a different manner and its activity does not depend on a functional DNA mismatch repair (MMR) mechanism. Synonyms: 4-[[4-[[4-[[4-(2-bromoprop-2-enoylamino)-1-methylpyrrole-2-carbonyl]amino]-1-methylpyrrole-2-carbonyl]amino]-1-methylpyrrole-2-carbonyl]amino]-N-[2-(diaminomethylideneamino)ethyl]-1-methylpyrrole-2-carboxamide; brostallicin; PNU 166196; PNU-166196; PNU166196. Grades: >98%. CAS No. 203258-60-0. Molecular formula: C30H36BrClN12O5. Mole weight: 723.58. | |
| Brostallicin hydrochloride | Brostallicin is a synthetic, alpha-bromoacrylic, second-generation minor groove binder (MGB), related to distamycin A, with potential antineoplastic activity. Brostallicin binds to DNA minor groove DNA, after having formed a highly reactive glutathione (GSH)-brostallicin complex in the presence of the enzyme glutathione S-transferase (GST), which is overexpressed in cancer cells; DNA replication and cell division are inhibited, resulting in tumor cell death. Compared to typical MGBs, this agent appears to bind covalently to DNA in a different manner and its activity does not depend on a functional DNA mismatch repair (MMR) mechanism. Accordingly, brostallicin may be effective against MMR-defective tumors that are refractory to various anticancer agents. Synonyms: PNU-166196; PNU 166196; PNU166196; 4-(2-bromoacrylamido)-N-(5-(5-(5-(2-guanidinoethylcarbamoyl)-1-methyl- 1H-pyrrol-3-ylcarbamoyl)-1-methyl-1H-pyrrol-3-ylcarbamoyl)-1-methyl-1H- pyrrol-3-yl)-1-methyl-1H-pyrrole-2-carboxamide. CAS No. 203258-38-2. Molecular formula: C30H36BrClN12O5. Mole weight: 760.05. | |
