Abstract

Synthesis and SAR of a series of 7-azaindoles as Orai channel inhibitors showing good potency inhibiting IL-2 production in Jurkat cells is described. Compound 14d displaying best pharmacokinetic properties was further characterized in a model of allergen induced asthma showing inhibition in the number of eosinophils in BALF. High lipophilicity remains as one of the main challenges for this class of compounds.

摘要

描述了一系列作为奥拉伊通道抑制剂的7-氮杂吲哚的合成及其构效关系,这些抑制剂在抑制Jurkat细胞中白细胞介素-2产生方面表现出良好的效力。对具有最佳药代动力学性质的化合物14d在变应原诱导的哮喘模型中进行了进一步表征,结果显示其对支气管肺泡灌洗液中嗜酸性粒细胞数量有抑制作用。高亲脂性仍然是这类化合物的主要挑战之一。
