scale-up totalsynthesis of largazole, a potent class I selective histone deacetylase (HDAC) inhibitor, a potential anticancer agent and also useful for the treatment of other disorders where transcriptional reprogramming might be beneficial. The synthetic route and conditions for each fragment and final product were modified and optimized to make them suitable for larger-scale synthesis. With the
在此,我们描述了拉格唑放大全合成工艺的研究和开发,拉格唑是一种有效的 I 类选择性组蛋白脱乙酰酶 (HDAC) 抑制剂,是一种潜在的抗癌药物,也可用于治疗转录重编程可能影响的其他疾病。有利。对每个片段和最终产物的合成路线和条件进行了修改和优化,使其适合大规模合成。通过我们开发的工艺,可以以良好到优异的产率合成数百克的每个片段和十克的最终产品拉格唑。根据最长序列,经过八个步骤,最终目标拉格唑的总产率为 21%,HPLC 纯度超过 95%。
