relationship studies of a novel sulfonylurea series of piperazine pyridazine-based small molecule glucan synthase inhibitors is described. The optimization of PK profiles within the series led to the discovery of several compounds with improved pharmacokinetic profiles which demonstrated in vitro potency against clinically relevant strains. However, the advancement of compounds from this series into a non-lethal
描述了一种新型的磺酰脲类哌嗪哒嗪基小分子葡聚糖合酶抑制剂的结构-活性关系研究。该系列中PK谱的优化导致发现了几种具有改善的药代动力学谱的化合物,这些化合物显示了对临床相关菌株的体外效力。然而,从该系列化合物发展成非致命的全身性真菌感染模型未能显示出体内功效。
