Description

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 Vitro

Antibiotic DC 81 shows cytotoxicity against human melanoma cell lines B16, A375, A2058, and RPMI7951, with IC50 values of 4.4 μM, 18.5 μM, 31.0 μM, and 41.5 μM, respectively[1][2].
Antibiotic DC 81 exhibits its biological activity by covalently binding to the N2 of guanine in the minor groove of DNA, via the electrophilic carbinolamine functionality at N10-C11[1].
Antibiotic DC 81 (4 μM, 24 h) induces mitochondria dependent apoptosis[2].

Apoptosis Analysis[2]

Cell Line: B16 melanoma cells
Concentration: 4 μM
Incubation Time: 24 h
Result: Induced mitochondria dependent apoptosis.
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].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
