  • PROCESS FOR THE PREPARATION OF ERIBULIN MESYLATE INTERMEDIATE
    申请人:RK Pharma Solutions LLC
    公开号:US20210040107A1
    公开(公告)日:2021-02-11
    The present application provides improved processes for the synthesis of eribulin intermediate, which generally comprise the steps of: a) De-protecting the eribulin-enone (compound 1) in tetrahydrofuran by using TBAF solution, buffered with imidazole HCl in the presence of molecular sieve and sodium sulphate to get an insitu mixture of eribulin-dione diastereomer at C12 carbon (compound 2). Then ketalization may be performed of eribulin-dione insitu intermediate containing mixture of diastereomer at C12 carbon (compound 2) with PPTS in dichloromethane to yield eribulin-diol (compound 3).
    本申请提供了改进的过程,用于合成厄立宾中间体,一般包括以下步骤:a)在四氢呋喃中使用TBAF溶液去保护厄立宾-烯酮(化合物1),在存在分子筛硫酸的情况下,缓冲使用盐酸咪唑,得到C12碳上厄立宾-二酮二对映异构体的原位混合物(化合物2)。然后,可以使用PPTS在二氯甲烷中对含有C12碳上二对映异构体混合物的厄立宾-二酮原位中间体进行缩酮化,得到厄立宾二醇(化合物3)。

    medicinal chemistry efforts on this scaffold have focused on oral bioavailability, brain penetration and efficacy against multidrug resistant (MDR) tumors by lowering the susceptibility of these compounds to P-glycoprotein (P-gp)-mediated drug efflux. Replacement of the 1,2-amino alcohol C32 side chain of eribulin with fragments neutral at physiologic pH led to the identification of analogs with significantly
    甲磺酸依里布林(Halaven™)是海洋聚醚大环内酯类盐菌素B的全合成类似物,最近在美国被批准用于治疗乳腺癌。日本和欧盟目前也正在对其进行监管审查。我们在该支架上继续进行的药物化学研究集中在通过降低这些化合物对P糖蛋白(P-gp)介导的药物外排的敏感性,从而提高了口服生物利用度,脑部渗透性和抗多药耐药性(MDR)肿瘤的功效。用生理pH值中性的片段替换eribulin的1,2-基醇C32侧链导致鉴定出具有明显更低的P-gp敏感性的类似物。这些类似物在体外对敏感和MDR细胞系均保持低至亚nM的效力。在这个系列中,亲脂性的提高通常会导致P-gp敏感性降低。除了在细胞培养中的效力外,这些化合物在小鼠异种移植模型中还显示出体内活性。

    Eribulin mesylate is a newly approved treatment for locally advanced and metastatic breast cancer. We targeted oral bioavailability and efficacy against multidrug resistant (MDR) tumors for further work. The design, synthesis and evaluation of novel amine-containing analogs of eribulin mesylate are described in this part. Attenuation of basicity of the amino group(s) in the C32 side-chain region led to compounds with low susceptibility to PgP-mediated drug efflux. These compounds were active against MDR tumor cell lines in vitro and in xenograft models in vivo, in addition to being orally bioavailable. (C) 2011 Elsevier Ltd. All rights reserved.
