substituted 4,5,6,7-tetrahydrothieno[3,2-c]- and -[2,3-c]pyridines, is described. Optimisation of this series involved solution phase combinatorial synthesis and very potent compounds were prepared with IC50 values down to 140 nM. The structure activity relationship (SAR) of these compounds indicates that: a tetrahydrothieno[3,2-c]pyridine core ring system and the isomeric [2,3-c] system are equipotent and much
描述了发现第一类有效的葡萄糖-6-磷酸酶催化位点抑制剂,即取代的4,5,6,7-四氢噻吩并[3,2-c]-和-[2,3-c]吡啶。该系列的优化涉及溶液相组合合成,并且制备的强效化合物的IC50值低至140 nM。这些化合物的结构活性关系(SAR)表明:四氢噻吩并[3,2-c]吡啶核环系统和异构体[2,3-c]系统是等位的,并且比相应的苯并类似物好得多,1 2,3,4-四氢异喹啉。四氢噻吩并[3,2-c]吡啶环的4-取代基必须是苯基,任选被亲脂性4-取代基如三氟甲氧基或氯取代。四氢噻吩并[3,2-c]吡啶环的5-取代基必须是取代的苯甲酰基;异戊基和(E)-3-呋喃-3-基丙烯酰基是所研究的最佳基团。似乎禁止在苯甲酰基邻位取代,而仅当存在甲氧基对位取代基时才容许在间位取代。这些SAR结果与在4,5,6,7-四氢噻吩并[2,3-c]吡啶系统中获得的结果相似。在酶识别中观察到对映选择性,并且该活性仅在一种对映异构体中存在于所有情况下。
