Metformin is a potent antidiabetic agent and currently used as a first-line treatment for patients with type 2 diabetes. Unfortunately, the moderate absorption and uncomfortable gastrointestinal adverse effects associated with metformin therapy impair its use. In this study, two novel prodrugs of a biguanidine functionality containing antidiabetic agent, metformin, were designed, synthesized, and evaluated in vitro and in vivo to accomplish improved lipophilicity and, consequently, enhanced oral absorption of this highly water-soluble drug. These results represent that the more lipophilic prodrug 2a biotransformed quant. to metformin mainly after absorption. The enhanced oral absorption consequently promoted the bioavailability of metformin from 43% to 65% in rats. Thus, this novel prodrug may offer a solution to reduce the required daily doses of metformin, which may decrease the uncomfortable adverse effects associated with metformin therapy. In the experiment, the researchers used many compounds, for example, 2-(Phenylthio)isoindoline-1,3-dione (cas: 14204-27-4Recommanded Product: 14204-27-4).
2-(Phenylthio)isoindoline-1,3-dione (cas: 14204-27-4) belongs to indole derivatives. Indole is an important structural motif of various drugs, therapeutic leads besides its prevalence in numerous natural products, agrochemicals, perfumery, and dyes. Indole plays a fundamental role for QS in E. coli, being one of the signal molecules responsible for the transcription of a variety of genes (gabT, and tnaB ASTD). Recommanded Product: 14204-27-4
