  Tricyclic pharmacophore-based molecules as novel integrin αvβ3 antagonists. Part III: Synthesis of potent antagonists with αvβ3/αIIbβ3 dual activity and improved water solubility

  摘要：

  In order to optimize our novel integrin alpha(v)beta(3)/alpha(IIb)beta(3) dual antagonists, spatial screening at the N-terminus was performed. The alpha(v)beta(3) antagonistic activity varied depending on the space that was occupied by the N-terminus, but high potency against alpha(IIb)beta(3) was well maintained. The (3S)-aminopiperidine analogue had the strongest activity against alpha(v)beta(3), and the S isomer at piperidine was more potent than the R isomer. Compounds selected on the basis of SAR analysis of a novel lead compound showed acceptable early absorption, distribution, metabolism, excretion, and toxicity (ADMET) profiles and sufficient water solubility for use as infusion drugs. Docking studies with the alpha(v)beta(3) receptor were performed to confirm the SAR findings. (c) 2005 Elsevier Ltd. All rights reserved.
