In Vitro	Rebeccamycin is an antitumor antibiotic produced by the actinomycete Saccharotrix aerocolonigenes with activity against several human tumor cell lines, including A549 (lung adenocarcinoma), HCT-116 (colon carcinoma), and KB (nasopharyngeal carcinoma) [1]. Rebeccamycin shows antibacterial activity against several Gram-positive bacteria, including Staphylococcus aureus and Streptococcus faecalis[3].
In Vivo	Rebeccamycin (2-256 mg/kg; i.p.; daily for 9 days) prolongs survival in B16 melanoma, L1210 leukemia[2]. Animal Model: CDF1 mice (B16 melanoma, L1210 leukemia)[2] Dosage: 2, 4, 8, 16, 32, 64, 128, 256 mg/kg Administration: I.p.; daily for 9 days Result: Prolongation of survival of the mice at dose levels ranging from 8 to 256 mg/kg.
