| Uses | Antibiotic DC 81 (DC 81), an antitumor antibiotic produced by Streptomyces species, is a PBD (pyrrolo[2,1-c][1,4]benzodiazepine). Antibiotic DC 81 is potent inhibitor of nucleic acid synthesis. Antibiotic DC 81 can recognize and bind to specific sequences of DNA and form a labile covalent adduct[1][2]. | | in vivo | Antibiotic DC 81 (0-10 mg/kg, i.p., at day 4, 7, 10, 13 after tumor cell injection) decreases the tumor burden in tumor-bearing mice, but the Antibiotic DC 81 at 10 mg/kg impairs cardiac muscle enzyme and liver function significantly[2]. | Animal Model: | Female C57BL/6 mice (8-12 weeks old, B16 cells were injected into the tail veins of mice)[2] | | Dosage: | 0.1, 1, 10 mg/kg | | Administration: | i.p., at day 4, 7, 10, 13 after tumor cell injection | | Result: | Substantially decreased the tumor burden by 20% at 1 mg/kg. DC-81 at 10 mg/kg induced an 8-10-fold increase of GPT and a 6-8-fold increase in CPK, which indicated severe impaired liver function and muscle damage. Did not impair significant renal function as demonstrated by serum creatinine. |
