modification of the 4-piperidinethio moiety, as a spacer of the first pleuromutilin analogues 2A and 2B having a purine ring, led to discovery of the novel pleuromutilin derivatives 14B and 17B. These compounds with good solubility in water showed promising in vitro antibacterial activity against various Gram-positive bacteria including MRSA, PRSP, and VRE and have potent in vivo efficacy.
作为具有嘌呤环的第一截短侧耳素类似物2A和2B的间隔基,对4-哌啶硫基部分的结构修饰导致发现了新的截短侧耳素衍生物14B和17B。这些在水中具有良好溶解性的化合物显示出对各种革兰氏阳性细菌(包括MRSA,PRSP和VRE)的有希望的体外抗菌活性,并具有强大的体内功效。
