The natural product trapoxin (76; Scheme 16) was reported
to be an irreversible inhibitor of HDACs in 1993, but in
contrast to TSA, it was found to demonstrate some selectivity
against class I and class II HDACs, inhibiting HDAC1 and HDAC4 but not HDAC6.223 Combination of structural
features of trapoxin, TSA, and another potent HDAC
inhibitor, the marine natural product psammaplin A (77;
Scheme 16), resulted in the de novo synthesis of NVP-LAQ-
824 (dacinostat) (78; Scheme 16), which inhibits HDAC and
the proliferation of cancer cell lines at low nanomolar
concentrations; it showed efficacy in a number of solid tumor
xenograft models, advancing to phase I clinical trials in
2002,224,225 but was discontinued by Novartis in 2005. The
full history of its evolution has been reviewed
