    • A novel class of compounds has been identified that inhibit PTP-1B through a newly discovered binding interaction. Methods of treating, preventing or delaying the onset of, conditions mediated by PTP-1B are also provided. The compounds are capable of interacting with the primary binding pocket of PTP-1B via a hydrogen bond acceptor and have an aqueous phase free energy more positive than about −1200 kJ/mol. Representative compounds in the class are those of Formula I: or an optical isomer, enantiomer, diastereomer, racemate or racemic mixture thereof, ester, prodrug or metabolite form, or a pharmaceutically acceptable salt thereof, wherein R1, R2 and/or R3 are independently hydrogen atoms or alkyl groups and G1 and G2 are aryl, heteroaryl, alkyl, arylalkanyl, arylalkenyl, arylalkynyl, heteroarylalkanyl, heteroarylalkenyl, or heteroarylalkynyl moieties.
    • 已经鉴定出新类化合物通过新发现的结合相互作用抑制PTP-1B。 还提供了治疗,预防或延缓由PTP-1B介导的病症发作的方法。 该化合物能够通过氢键受体与PTP-1B的主要结合口相互作用,并且具有比约-1200kJ / mol更正的水相游离能。 该类中的代表性化合物是式I的那些:或其旋光异构体,对映体,非对映异构体,外消旋体或外消旋混合物,酯,前药或代谢物形式或其药学上可接受的盐,其中R 1, R 2和/或R 3独立地是氢原子或烷基,G 1和G 2是 芳基,杂芳基,烷基,芳基烷基,芳基烯基,芳基炔基,杂芳基烷基,杂芳基烯基或杂芳基炔基部分。
