Abstract

Thirty-six novel acylurea connected straight chain hydroxamates were designed and synthesized. Structure-activity relationships (SAR) were established for the length of linear chain linker and substitutions on the benzoylurea group. Compounds 5g, 5i, 5n, and 19 showed 10-20-fold enhanced HDAC1 potency compared to SAHA. In general, the cellular potency pIC(50) (COLO205) correlates with enzymatic potency pIC(50) (HDAC1). Compound 5b (SB207), a structurally simple and close analogue to SAHA, is more potent against HDAC1 and HDAC6 compared to the latter. As a representative example of this series, good in vitro enzymatic and cellular potency plus an excellent pharmacokinetic profile has translated into better efficacy than SAHA in both prostate cancer (PC3) and colon cancer (HCT116) xenograft models.
