Description

一种三嗪二酮类衍生物的晶型及制备方法 技术领域
本公开属于制药领域,涉及一种三嗪二酮类衍生物的晶型,具体的,涉及(S)-6-((1-(2-氟-5-甲基苯基)乙基)氨基)-3-(四氢-2H-吡喃-4-基)-1,3,5-三嗪-2,4(1H,3H)-二酮的晶型及其制备方法。
背景技术
肥厚型心肌病(HCM)是一种与基因突变相关的显性遗传性心肌疾病。全球发病率约为0.2%,是导致35岁以下年轻人猝死的最重要原因(Tuohy,CV.et al.,Eur J Heart Fail,22,2020,228-240)。临床上表现出来的特征为左室壁呈不对称性肥厚,常侵及室间隔,心室内腔变小,左心室血液充盈受阻,心室舒张期顺应性下降。根据左心室流出道有无梗阻分为梗阻性及非梗阻性肥厚型心肌病。现临床上对于肥厚型心肌病的治疗多采用β-阻断剂和钙离子通道阻断剂来降低心脏收缩,缓解症状。但这些治疗都是治标不治本。HCM进展到晚期只能进行心脏移植(Ramaraj,R.Cardiol Rev,16,2008,172-180)。因而找到一种针对HCM发病根源的治疗方法非常迫切。
现有研究发现70%的HCM病人都是由于肌节蛋白基因突变导致的。其中5-7%的病人中发现多个位点突变。现已确定约70多个致病突变,但这些突变大多都具有家族特异性,仅有少数几个热点被确定,例如MYH7R403Q和R453C突变(Frey,N.et al.,Nat Rev Cardiol,9,2011,91-100;Sabater-Molina,M.et al.,Clin Genet,93,2018,3-14)。针对基因突变致病机率的研究发现MYH7基因突变病人约占30%。相比较于其他肌节蛋白基因,MYH7会导致疾病早发以及更严重的心肌肥大。肌球蛋白是肌原纤维粗肌丝的组成单位,在肌肉运动中起重要作用。其分子形状如豆芽状,由两条重链和多条轻链构成。肌球蛋白头部与肌动蛋白结合形成横桥,使肌球蛋白的ATP酶活性大大提高,催化ATP水解反应,产生能量促使横桥滑动,进行肌肉收缩。研究结果表明MYH7基因突变会导致肌球蛋白ATP酶活性升高,肌球蛋白super-relaxed state(SRX)比例降低,肌球蛋白和肌动蛋白间的横桥增加,从导致心脏收缩功能异常(Green,EM.et al.,Science,351,2016,617-621;Sommese,RF.et al.,Proc Natl Acad Sci U S A,110,2013,12607-12612)。因此肌球蛋白是治疗肥厚型心肌病的重要靶点。
申请号为WO2022105852的申请中提供了一系列三嗪二酮类衍生物并进行了结构表征,其中包括(S)-6-((1-(2-氟-5-甲基苯基)乙基)氨基)-3-(四氢-2H-吡喃-4-基)-1,3,5-三嗪-2,4(1H,3H)-二酮。另外,该申请还对(S)-6-((1-(2-氟-5-甲基苯基)乙基)氨基)-3-(四氢-2H-吡喃-4-基)-1,3,5-三嗪-2,4(1H,3H)-二酮进行了生物学评价,结果显示化合物对肌球蛋白ATPase酶具有很好的抑制作用。
药用活性成分的晶型结构往往影响到药物的化学稳定性,结晶条件及储存条件的不同有可能导致化合物的晶型结构的变化,有时还会伴随着产生其他形态的晶型。一般来说,无定型的药物产品没有规则的晶型结构,往往具有其它缺陷,比如产物稳定性较差,析晶较细, 过滤较难,易结块,流动性差等。因此,改善上述产物的各方面性质是很有必要的,我们需要深入研究找到晶型纯度较高并且具备良好物化稳定性的晶型。
