Tolimidone (CP-26154; MLR-1023) is a compound which was discovered by scientists at Pfizer, was found to stimulate secretion of gastric mucosa, and was in development by Pfizer as a drug candidate to treat gastric ulcers but was abandoned.[1][2][3][4] After the patent on the compound expired, scientists at the company Melior Discovery identified it as a potential drug candidate for diabetes through a phenotypic screen.[4] The company proceeded to show that MLR-1023 is an allosteric activator of Lyn kinase with an EC50 of 63 nM.[5][6] As of 2012 Melior was repurposing it for diabetes.[1][7] In June 2016, the company reported positive results from their Phase 2a clinical study in diabetic subjects[8][9]
