Abstract:

This paper describes a high-throughput screening study aimed at identifying inhibitors of human intestinal calcium-activated chloride channels (CaCCs). CaCCs play an important role in intestinal fluid secretion and other physiological functions. Using a high-throughput screening method, the authors identified several compounds from a chemical library that could inhibit CaCCs, and described their inhibitory effects and potential applications in detail.
