3,5-diaryl-4,5-dihydropyrazoles were discovered to be potent KSP inhibitors with excellent in vivo potency. These enzyme inhibitors possess desirable physical properties that can be readily modified by incorporation of a weakly basic amine. Careful adjustment of amine basicity was essential for preserving cellular potency in a multidrug resistant cell line while maintaining good aqueous solubility
发现3,5-二芳基-4,5-二氢吡唑是有效的KSP抑制剂,具有出色的体内效力。这些酶抑制剂具有所需的物理性质,可以通过掺入弱碱性胺来容易地对其进行修饰。仔细调整胺的碱性对于保持耐多药性细胞系中的细胞效能同时保持良好的水溶性至关重要。
