targeting microtubule of cancer cells, has been currently tried in its phase III clinical study. However, low efficacy caused by poor pharmacokinetic (PK) properties has been considered to be the main obstacle to approved by the Food and Drug Administration. Herein, we introduced a deuterium atom as an isostere in its structure to become a new compound named (MBRI-001, No. 9 in a series of deuterium-substituted
Plinabulin是一种靶向癌细胞微管的药物,目前已在其III期临床研究中进行了尝试。但是,由不良的药代动力学(PK)性能引起的低功效已被认为是食品药品监督管理局批准的主要障碍。在本文中,我们引入了
氘原子作为其等排体,以使其成为新的化合物(MBRI-001,一系列
氘取代的化合物中的第9号)。MBRI-001的结构通过HRMS,NMR,IR和单晶分析进行了表征。MBRI-001的药代动力学特征优于匹林布林。另外,其对于多种癌
细胞系的抗肿瘤活性处于低纳摩尔
水平,并且对于在小鼠静脉内施用中异化的人NCI-H460具有高活性。重要的,与
多西他赛相比,连续给药MBRI-001的毒性较低。因此,我们建议MBRI-001可以在不久的将来作为有前途的抗癌药开发。
