Abstract

Optimization of a 7-azaindole-3-acetic acid CRTh2 receptor antagonist chemotype derived from high throughput screening furnished a highly selective compound NVP-QAV680 with low nM functional potency for inhibition of CRTh2 driven human eosinophil and Th2 lymphocyte activation in vitro. The molecule exhibited good oral bioavailability in the rat, combined with efficacy in rodent CRTh2-dependent mechanistic and allergic disease models and was suitable for clinical development.

摘要

高通量筛选得到的 7-氮杂吲哚-3-乙酸 CRTh2 受体拮抗剂化合物类型经过优化,得到了一个高选择性的化合物 NVP-QAV680,其对 CRTh2 驱动的人嗜酸性粒细胞和 Th2 淋巴细胞体外激活的抑制具有低纳摩尔功能性效力。该分子在大鼠体内具有良好的口服生物利用度,结合了在啮齿动物 CRTh2 依赖性机制和过敏疾病模型中的疗效,适合临床开发。
