Potency Gracillin was cytotoxic against most cell lines with GI(50), TGI and LC(50) at micromolar levels, but no activity against EKVX (non-small cell lung cancer), HT29 (colon cancer), OVCAR-5 (ovarian cancer), and SN12C (renal cancer).
Cell line/ mice model CCRF-CEM, RPMT-8226, KM12, SF-539, U251, M14, 786-0, DU-145, MDA-MB-435
Additional information  Put all in together, methyl protoneogracillin has been selected as a potential anticancer candidate for hollow fi ber assay to nude mice, but gracillin will not be pursued due to lack of selectivity against human cancer diseases.
