Provided are a series of novel pyridine or pyrimidine derivatives which inhibit CDK9 and may be useful for the treatment of hyperproliferative diseases. In particular the compounds are of use in the treatment of proliferative disease such as cancer including hematological malignancies such as acute myeloid leukemia, multiple myeloma, chronic lymphocytic leukemia, diffuse large B cell lymphoma, Burkitt's lymphoma, follicular lymphoma and solid tumors such as breast cancer, lung cancer, neuroblastoma and colon cancer.
safety of the chemistry involved. With several steps involving volatile, reactive, and non-UV active materials, reaction optimization was facilitated by implementing off-line 1H NMR analysis of crude mixtures. Key transformations targeted for process development included a Wolff–Kishner reduction, an iridium-catalyzed borylation, and enzymatic resolution of a racemic amino-ester.
以第一代药物化学合成为起点,我们在此描述了AZD4573的工艺开发,这是一种肿瘤学候选药物。除了提高产量和去除色谱步骤之外,我们还解决了其他因素,例如起始材料的可用性以及所涉及的化学物质的安全性。通过涉及挥发性、反应性和非 UV 活性材料的几个步骤,通过对粗混合物进行离线1 H NMR 分析,促进了反应优化。针对工艺开发的关键转化包括 Wolff-Kishner 还原、铱催化的硼化和外消旋氨基酯的酶拆分。
