A series of novel imperatorin derivatives were synthesized from commercially available xanthotoxin. The in vitro pharmacological evaluation indicated that all of the compounds possessed potent vasodilatory activity. Among them, compounds (5b), (5d) and (5e) exhibited higher vasdilatory activity (with EC50 values of 0.68 μM, 0.59 μM and 0.49 μM, respectively) than imperatorin (EC50 = 1.12 μM). The program Volsurf was used to predict the derivatives' ADME relevant descriptors. The results suggested that these novel compounds had a potential interest for the development of novel and potent vasorelaxant agents.
研究人员从市售的黄腐毒素中合成了一系列新型黄腐素衍生物。体外药理评估表明,所有化合物都具有强效的血管扩张活性。其中,化合物(5b)、(5d)和(5e)的血管舒张活性(EC50 值分别为 0.68 μM、0.59 μM 和 0.49 μM)高于黄藤素(EC50 = 1.12 μM)。研究人员使用 Volsurf 程序预测了衍生物的 ADME 相关描述符。结果表明,这些新型化合物具有开发新型强效血管舒张剂的潜在兴趣。
