  Synthesis, antiproliferation, and docking studies of N-phenyl-lipoamide and 8-mercapto-N-phenyloctanamide derivatives: effects of C6 position thiol moiety

  摘要：

  Some N-phenyl lipoamide and 8-mercapto-N-phenyloctanamide derivatives were synthesized and their in vitro antiproliferative activity was evaluated. The experimental results indicated that 8-mercapto-N-phenyloctanamides might be good histone deacetylase inhibitors rather than N-phenyl lipoamides, who had thiol moiety at C6 position. To verify the antiproliferation data on structural basis, in silico docking studies of the representative compounds into the crystal structure of histone deacetylase-like protein using AutoDock 4.0 program were performed. Furthermore, sulfur acetylated 8-mercapto-N-phenyloctanamide improved its in vitro antiproliferative activity, probably due to the increasing of its cell membrane permeability. While the identification of enzymatic target of N-phenyl lipoamides with dithiolane is still ongoing.

  The present invention relates to bi-functional compounds which function to recruit endogenous proteins to an E3 ubiquitin ligase for degradation, and methods for using same. More specifically, the present disclosure provides specific proteolysis targeting chimera (PROTAC) molecules which find utility as modulators of targeted ubiquitination of a variety of polypeptides and other proteins, in particular the androgen receptor of a slice variant of AR which lacks the LBD, labelled as AR-V7, which are then degraded and/or otherwise inhibited by the compounds as described herein.
