Polmacoxib

Polmacoxib (CG100649) is a first-in-class, orally active nonsteroidal anti-inflammatory drug (NSAID) which is a dual inhibitor of COX-2 (IC50 around 0.1 μg/ml) and carbonic anhydrase[1]. Polmacoxib inhibits colorectal adenoma and tumor growth in mouse models[2].

Polmacoxib (CG100649) (0-1 μg/ml; 24 hours; HCA-7 and HT-29 cells) can inhibit COX-2 activity and PGE2 production in human colon cancer cells, at lower concentrations compared to Celecoxib[2].

Polmacoxib (7 mg/kg; p.o.; daily for 8 weeks) suppresses intestinal polyp formation in ApcMin/+ mice[2]. Polmacoxib (7-15 mg/kg; p.o.; daily from day 27 post-injection to day 111; athymic nude mice; subcutaneous xenograft mouse model) reduces tumor volume and tumor weight by 58% and 48%, respectively, compared to a 48% and 36% reduction following treatment with Celecoxib[2]. Polmacoxib (7-15 mg/kg; p.o.; began on day 14 and continued for 8 weeks; athymic nu/nu mice; orthotopic xenograft mouse model) inhibits CRC growth in an orthotopic xenograft mouse model, reducing tumor weight by 70% using 7 mg/kg or by 83% using 15 mg/kg, compared to a similar 70% reduction following treatment with 500 mg/kg of Celecoxib[2].
