novel chemical scaffolds and new modes of action is of great importance. Herein, new β-hexahydrocarboline derivatives are shown to possess potent anticryptococcal activities. In particular, compound A4 showed potent in vitro and in vivo anticryptococcal activity with good metabolic stability and blood-brain barrier permeability. Compound A4 was orally active and could significantly reduce brain fungal
由于缺乏有效和安全的药物疗法,隐球菌性脑膜炎(CM)的临床治疗仍然是一项重大挑战。开发具有新型化学支架和新作用方式的新型CM治疗剂非常重要。在此,新的β-六烃基衍生物显示出具有有效的抗隐球菌活性。特别地,化合物A4显示出有效的体外和体内抗隐球菌活性,具有良好的代谢稳定性和血脑屏障通透性。化合物A4具有口服活性,可在CM鼠模型中显着减轻脑部真菌的负担。此外,化合物A4可以抑制新型隐球菌的几种毒力因子,并可能以新的作用方式起作用。初步的机理研究表明,化合物A4通过作用于Cdc25c / CDK1 / cyclin B途径,诱导了DNA双链断裂和细胞周期阻滞在G2期。综上所述,β-六烃基A4代表了开发下一代CM治疗剂的有前途的先导化合物。
