以ANO1蛋白为靶点的钙激活氯通道调节剂研究进展

A review of ANO1-based calcium activated chloride channel modulators

钙激活氯通道是广泛存在于人体内的一种阴离子通道,参与分泌、心肌细胞去极化、神经信号传导等多种生理活动。ANO1蛋白是钙激活氯通道的分子基础之一,对ANO1蛋白进行调节能够产生多种药效作用,例如镇痛、治疗痢疾、哮喘、抑制肿瘤等。近10年来发展出许多ANO1蛋白调节剂筛选测试方法,虽然筛选出一系列以ANO1蛋白为靶点的钙激活氯通道调节分子,但是这些分子的药理学作用却并不一致。本文从筛选方法、构效关系、潜在应用前景等多方面对ANO1蛋白调节分子的研究进展进行论述。

Calcium-activated chloride channel（CaCC） is an anion channel, widely distributed in the human body, taking a part in cell functions including secretion, heart muscle repolarization, nerve signal transmission and several physiological activities. The anoctamin 1（ANO1） protein is the molecular basis of CaCC and the modification of ANO1 protein will produce a variety of pharmacological effects, such as analgesia, treating dysentery and asthma, even tumor proliferation and migration inhibition. In the past decade, many methods in screening of ANO1 regulators have been developed. Although a series of the ANO1-based CaCC regulatory molecules have been identified, the pharmacological effects of these molecules are not consistent. In this review, we introduce ANO1 protein regulators from many aspects including bio-test methods, structure-activity relationships, and the potential applications.
