and in vitro biological activity of a series of novel coumarin inhibitors of gyrase B is presented. Replacement of the 3-acylamino residue (3-NHCOR) of coumarin drugs with reversed isosteres C(=O)R, C(=N-OR)R', COOR, CONHR and CONHOR leads to highly potent analogues which displayed excellent inhibition of the negative supercoiling of the relaxed DNA and antibacterial activity.
介绍了一系列新型促旋酶B香豆素抑制剂的设计,合成和体外生物学活性。用反向等排体C(= O)R,C(= N-OR)R',COOR,CONHR和CONHOR取代香豆素药物的3-酰基氨基残基(3-NHCOR)产生了高效的类似物,该类似物表现出出色的抑制作用松弛的DNA的负超螺旋和抗菌活性。
