A series of 3-aryl(pyrrolidin-1-yl)butanoic acids were synthesized using a diastereoselective route, via a rhodium catalyzed asymmetric 1,4-addition of arylboronic acids in the presence of (R)-BINAP to a crotonate ester to provide the (S) absolute configuration for the major product. A variety of aryl substituents including morpholine, pyrazole, triazole, imidazole, and cyclic ether were screened in cell adhesion assays for affinity against αvβ1, αvβ3, αvβ5, αvβ6, and αvβ8 integrins. Numerous analogs with high affinity and selectivity for the αvβ6 integrin were identified. The analog (S)-3-(3-(3,5-dimethyl-1H-pyrazol-1-yl)phenyl)-4-((R)-3-(2-(5,6,7,8-tetrahydro-1,8-naphthyridin-2-yl)ethyl)pyrrolidin-1-yl)butanoic acid hydrochloride salt was found to have very high affinity for αvβ6 integrin in a radioligand binding assay (pKi = 11), a long dissociation half-life (7 h), very high solubility in saline at pH 7 (>71 mg/mL), and pharmacokinetic properties commensurate with inhaled dosing by nebulization. It was selected for further clinical investigation as a potential therapeutic agent for the treatment of idiopathic pulmonary fibrosis.

在(R)-BINAP存在下,通过铑催化的芳基硼酸的不对称1,4-加成反应,使用非对映选择性路线合成了一系列3-芳基(吡咯烷-1-基)丁酸主要产品的(S)绝对配置。包括吗啉,吡唑,三唑,咪唑,和环醚的各种芳基取代基中的细胞粘附试验中筛选针对α亲和力v β 1,α v β 3,α v β 5,α v β 6,α v β 8整联蛋白。具有高亲和力和选择性的α众多类似物v β 6整联进行鉴定。类似物(S)-3-(3-(3,5-二甲基-1 H-吡唑-1-基)苯基)-4-((R)-3-(2-(5,6,7,8 -四氢-1,8-萘啶-2-基)乙基)吡咯烷-1-基)丁酸盐酸盐被发现具有为α非常高的亲和力v β 6整联在放射性配体结合测定(对ķ我= 11),较长的解离半衰期(7 h),在pH 7的盐水中具有很高的溶解度(> 71 mg / mL)和药代动力学特性,与通过雾化吸入给药相当。它被选作进一步的临床研究,作为治疗特发性肺纤维化的潜在治疗剂。
