莫努匹拉韦(MK-4482,EIDD-2801)是一种有前途的口服生物可利用候选药物,用于治疗COVID-19。在此,我们描述了一种以供应为中心的无色谱法合成莫努匹韦从胞苷,由两个步骤组成:选择性酶促酰化,然后转氨,以产生最终的药物产品。这两个步骤都在十克规模上成功地进行了:第一步为200 g,第二步为80 g。总体而言,与专利路线中最高17%的分离产率相比,以41%的总分离产率获得了莫努匹韦。这种途径提供了许多优势,在专利文献中描述的初始途径,并将降低这种药物的成本,如果它证明在正在进行的临床试验中安全和有效。
Molnupiravir (MK-4482, EIDD-2801) is a promising orally bioavailable drug candidate for the treatment of COVID-19. Herein, we describe a supply-centered and chromatography-free synthesis of molnupiravir from cytidine, consisting of two steps: a selective enzymatic acylation followed by transamination to yield the final drug product. Both steps have been successfully performed on a decagram scale: the first step at 200 g and the second step at 80 g. Overall, molnupiravir has been obtained in a 41% overall isolated yield compared to a maximum 17% isolated yield in the patented route. This route provides many advantages to the initial route described in the patent literature and would decrease the cost of this pharmaceutical should it prove safe and efficacious in ongoing clinical trials.
