Abstract

Bromodomain and extraterminal domain (BET) subfamily members are intriguing targets for Cancer treatment. Most of the reported BET inhibitors were monovalent inhibitors. Recently, some bivalent inhibitors were disclosed, which bound to two bromodomains simultaneously. They had good activities, however, most of them also showed unsatisfactory pharmacokinetic properties, which were caused by long chain linkers. Based on our previous work on monovalent BRD4 inhibitors, we designed and synthesized a series of novel bivalent inhibitors with short and hydrophilic linkers. These compounds exhibited better activities than the corresponding monovalent inhibitors and good pharmacokinetic properties. Compound 21 showed excellent in vitro activities. And it also demonstrated potent in vivo antitumor efficacy under oral administration and was well tolerated in in vivo tests.
