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.

The kineticresolution of 3-aminopyrrolidine (3AP) and 3-aminopiperidine (3APi) with ω-transaminases was facilitated by the application of a protecting group concept. 1-N-Cbz-protected 3-aminopyrrolidine could be resolved with >99% ee at 50% conversion, the resolution of 1-N-Boc-3-aminopiperidine yielded 96% ee at 55% conversion. The reaction rate was up to 50-fold higher by using protected substrates
应用保护基概念可以促进3-氨基吡咯烷(3AP)和3-氨基哌啶(3APi)与ω-转氨酶的动力学拆分。1 - N -Cbz保护的3-氨基吡咯烷在50%的转化率下可通过> 99%ee拆分,1 - N -Boc-3-氨基哌啶的拆分在55%的转化率下可得到96%ee。通过使用受保护的底物,反应速率高达50倍。最重要的是,与未保护的底物相比,氨基甲酸酯保护后的对映选择性显着提高(86 %vs. 99%ee))。出人意料的是,3AP的苄基保护对对映选择性没有影响。对此的可能解释可能是由NMR光谱证实的苄基或氨基甲酸酯保护的3AP的不同柔韧性。
Tricyclic pharmacophore-based molecules as novel integrin αvβ3 antagonists. Part IV: Preliminary control of αvβ3 selectivity by meta-oriented substitution
antagonists based on the RGD recognition pattern or on modification of the dihedral angle between the central benzene ring and the adjacent heterocycle, but both proved unsuccessful. However, synthesis of novel antagonists with meta-substitution of the central benzene ring generated weak selectivity for alphavbeta3 over alphaIIbbeta3 for the first time in the family of compounds with the tricyclic pharmacophore
