"Fourteen agents were synthesized from the combination of two alkyne and seven azido precursors. The inhibition of HDAC1 and HDAC8 was then determined by in vitro enzymatic assays, after which the cytotoxicity was evaluated in the NCI human cancer cell line screen. A lead compound 5g (NSC746457) was discovered that inhibited HDAC1 at an IC50 value of 104 +/- 30 nM and proved quite potent in the cancer cell line screen with GI(50) values ranging from 3.92 mc M...
