A series of new 2-(1-(2-(substituted-phenyl)-5-methyloxazol-4-yl)-3-(2-substitued-phenyl)-4,5-dihydro-1H-pyrazol-5-yl)-7-substitued-1,2,3,4-tetrahydroisoquinoline derivatives were synthesized. The results showed that compounds 9q and 10q can strongly inhibit Staphylococcus aureus DNA gyrase and Bacillus subtilis DNA gyrase (with IC50s of 0.125 and 0.25 μg/mL against S. aureus DNA gyrase, 0.25 and 0
一系列新的2-(1-(2-(取代-苯基)-5-甲基恶唑-4-基)-3-(2-取代-苯基)-4,5-二氢-1 H-吡唑-5-基)-7-取代的-合成1,2,3,4-四氢异喹衍生物。结果表明,化合物9Q和10Q能强烈抑制金黄色葡萄球菌的DNA促旋酶和枯草芽孢杆菌的DNA促旋酶(与IC 50年代的0.125和针对0.25微克/毫升的金黄色葡萄球菌的DNA促旋酶, 0.25和0.125微克/毫升抗枯草芽孢杆菌DNA促旋酶)。根据生物学结果,还讨论了结构-活性关系。
