| Description | FR901464 (WB 2663B) is potent cytotoxic natural products that share an amine-containing tetrahydropyran ring. |
| In vitro | FR901464 (10-20 ng/ml; 6-24 hours) inhibited the growth of solid tumors, colon cancer, and methoxamine A fibrosarcoma in mice. FR901464 induced characteristic G1 and G2/M phase arrest in the cell cycle and internucleosomal degradation of genomic DNA in M-8 tumor cells by the same principle as SV40 promoter dependent cellular transcription. FR901464 (1-10 ng/ml) induced the transcription of some endogenous genes in M-8 cells, but did not inhibit the transcription of endogenous genes[1]. |
