The incidence of malignant melanoma has dramatically increased in recent years thus requiring the need for improved therapeutic strategies. In our efforts to design selective histone deactylase inhibitors (HDACI), we discovered that the aryl urea 1 is a modestly potent yet nonselective inhibitor. Structure-activity relationship studies revealed that adding substituents to the nitrogen atom of the urea so as to generate compounds bearing a branched linker group results in increased potency and selectivity for HDAC6. Compound 5g shows low nanomolar inhibitory potency against HDAC6 and a selectivity of similar to 600-fold relative to the inhibition of HDACI. These HDACIs were evaluated for their ability to inhibit the growth of B16 melanoma cells with the most potent and selective HDAC6I being found to decrease tumor cell growth. To the best of our knowledge, this work constitutes the first report of HDAC6-selective inhibitors that possess antiproliferative effects against melanoma cells.

The present invention relates to bicyclic himbacine derivatives of the formula or a pharmaceutically acceptable salt thereof, wherein: X is -O-, -N(R), -C(R8)(R9) or -C(O)-; and Y is -O-, -N(R), -C(R8)(R9) or -C(O)- and the remaining variables are described herein. The compounds of the invention are effective inhibitors of the PAR-1 receptor. The inventive compounds may be used for the treatment or prophylaxis of disease states such as ACS, secondary prevention of myocardial infarction or stroke, or PAD.
Disclosed are selective histone deactylase inhibitors (HDACi) that having Formula (I). Methods of making and using these inhibitors for the treatment of cancer, in particular melanoma are also disclosed.
