Provided are a hydroxyethyl sulfonate of a cyclin-dependent protein kinase inhibitor, a crystalline form thereof and a preparation method therefor. Specifically, 6-acetyl-8-cyclopentyl-5-methyl-2-((5-(piperidin-4-yl)pyridin-2-yl)amino)pyrido[2,3-d]pyrimidin-7(8H)-one hydroxyethyl sulfonate (compound of formula (I)), a crystal form I thereof and a preparation method therefor are provided. Crystal form I of the compound of formula (I) has good chemical and crystalline stability, low toxicity, and low residual crystallization solvent. Therefore, the crystal form I can be used in improved clinical therapy.
提供了一种环依赖性蛋白激酶抑制剂的羟乙基磺酸盐,其晶体形式以及制备方法。具体来说,提供了6-乙酰基-8-环戊基-5-甲基-2-((5-(哌啶-4-基)吡啶-2-基)氨基)吡啶[2,3-d]嘧啶-7(8H)-酮羟乙基磺酸盐(化合物式(I)),其晶体形式I以及其制备方法。化合物式(I)的晶体形式I具有良好的化学和晶体稳定性,低毒性和低残留结晶溶剂。因此,晶体形式I可用于改进的临床治疗。
