Structural 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.
作为具有嘌呤环的首个截短侧耳素类似物2A和2B的间隔基团，对4-哌啶硫基部分进行结构修饰，从而发现了新型截短侧耳素衍生物14B和17B。这些化合物在水中具有良好的溶解性，对包括耐甲氧西林金黄色葡萄球菌（MRSA）、耐青霉素肺炎链球菌（PRSP）和耐万古霉素肠球菌（VRE）在内的多种革兰氏阳性菌显示出有前景的体外抗菌活性，并且具有强大的体内疗效。
