In Vitro	FR901464 (10-20 ng/ml; 6-24 hours) inhibits the growth of murine solid tumors, Colon 38 carcinoma and Meth A fibrosarcoma. FR901464 induces characteristic G1 and G2/M phase arrest in the cell cycle and internucleosomal degradation of genomic DNA with the same kinetics as activation of SV40 promoter-dependent cellular transcription in M-8 tumor cells[1]. FR901464 (1-10 ng/ml; 16 hours) suppresses the transcription of some inducible endogenous genes but not house keeping genes in M-8 cells[1]. FR901464 exhibits potent anticancer activity. It shows enhancement of activity of a promoter of the SV40 DNA tumor virus at 10 nM concentration in M-8 cells[1].
