The N-hydroxycinnamamide/SA hybrids 9b-f and 9h showed good to moderate anti-tumor activities. Notably, compound 9e had a greater potency, comparable to vorinostat （SAHA）, in human colon carcinoma cells, which was probably, or at least partially, attributable to the positive effects of the chain length noted in allojlol amines. Furthermore, the HDAC inhibitory activities of 9e against Hela cell nuclear were also similar to that of vorinostat （SAHA）, while the tested compounds 9c-f did not exhibit any isoform selectivity in the inhibition of HDACs. In addition, compound 9e could selectively inhibit tumor cells, but not inhibit non-tumor cell proliferation in vitro. Our findings suggest that the N-hydroxycinnamamide/SA hybrids may hold significant promise as therapeutic a^ents for the intervention of human cancers.展开更多
