Description: Polmacoxib, also known as CG100649, is a first-in-class NSAID drug candidate that is a dual inhibitor of COX-2 and carbonic anhydrase (CA). CG100649's interaction with CA in red blood cells provides it with a novel 'tissue-specific' transport mechanism that is designed to deliver sustained levels of drug to inflamed tissues, while maintaining low systemic exposure. Its unique dual COX-2 and CA binding properties are designed to provide potentially superior safety to cardiovascular, renal, and gastrointestinal tissues compared to traditional NSAIDs or COX-2 inhibitor drugs. CG100649 inhibits premalignant and malignant colorectal lesions in mouse models, partly through inhibiting tumor cell proliferation.
