| Chartreusin | It is produced by the strain of Streptomyces chartreusis. It has the activity of anti-gram-positive bacteria and mycobacterium. Chartreusin is an antitumour antibiotic that binds to GC-rich tracts in DNA, with a clear preference for B-DNA over Z-DNA; inhibits RNA synthesis and causes single-strand scission of DNA via the formation of free radicals; a potent inhibitor of topoisomerase II. Synonyms: Lambdamycin; Antibiotic X-465A; NSC 5159; (1R,2R,3aS,8aR)-1-[(Z)-5-hydroxy-3-(hydroxymethyl)pent-3-enyl]-1-(hydroxymethyl)-2,5-dimethyl-2,3,4,7,8,8a-hexahydroazulene-3a-carbaldehyde; 10-[[6-Deoxy-2-O-(6-deoxy-3-O-methyl-α-D-galactopyranosyl)-β-D-galactopyranosyl]oxy]-6-hydroxy-1-methylbenzo[h][1]benzopyrano[5,4,3-cde][1]benzopyran-5,12-dione. Grades: >99% by HPLC. CAS No. 6377-18-0. Molecular formula: C32H32O14. Mole weight: 640.59. |  |
