Description
技术领域
本发明涉及有机及药物合成技术领域,具体涉及一种三氟甲基吡唑并七 元环化合物及其晶体结构和制备方法。
背景技术
三氟甲基(trifluoromethyl),有机氟化合物的官能团,化学式为-CF3,为 氟原子取代甲基(-CH3)上的所有氢原子而成,聚集高电负性,介于在氟和 氯之间。三氟甲基是一类重要的化学基团,因其有非常强的吸电作用,将其 引入生物活性分子上,能够使生物活性分子的脂溶性、代谢稳定性、生物利 用度等生物活性等大幅度增强,是药物中重要的结构基团。早在1928年, Lehmann等人就发表了其对一些简单三氟甲基有机化合物生物活性的检测结 果(Lehmann,F.,Arch.Exptl.Path.Pharmakol.,130,250(1928);C.A.,22, 2993(1928).),发现三氟甲基苯、间硝基三氟甲基苯、间三氟甲基苯甲酸和间 三氟甲基苯胺等化合物可对青蛙的中枢神经系统造成影响;间硝基三氟甲基 苯、间三氟甲基苯甲酸作为兴奋剂效果显著,而与之相反的是,间三氟甲基 苯胺的麻醉作用起效快、持续时间长,可作为镇静剂使用。随着技术的发展, 逐步发现三氟甲基可应用于肿瘤、感染性疾病、心脑血管疾病、神经系统疾 病、精神障碍、内分泌和代谢疾病、消化系统疾病、泌尿生殖系统疾病、肌肉骨骼、结缔组织疾病、眼病疾病和皮肤病等领域。例如抗炎药:塞莱昔布 (Celecoxib)、乌芬那酯(Ufenamate);抗精神失常药物:盐酸三氟丙嗪 (TriflupromazineHydrochloride)、盐酸氟哌噻吨(Flupenthixol Hydrochloride)、
杂环化合物广泛存在于天然产物、合成药物中,目前临床上使用的90% 以上的药物为杂环化合物,其中吡唑衍生物是一类非常重要的含氮杂环化合 物,具有广泛的生物活性,在制药工业中具有广泛的应用。吡唑母核是众多 药物中的基本结构之一,如抗炎药塞莱昔布(Celecoxib)、解热镇痛药安替比 林(Antipyrine)、自由基清除剂依达拉奉(Edaravone)、抗肿瘤药、抗病毒药 吡唑霉素(Pyrazofurin)、抗菌药磺胺苯吡唑(Sulfaphenazolum)、蛋白同化类 固醇类药司坦唑醇(Stanozolol)、中枢抑制药唑吡坦(Zolpidem)等都是含有 吡唑结构单元的药物。除此之外,七元含氧杂环在药物应用中也有着潜在的 应用价值。专利CN111440181A即公开了一种含喹啉结构的二吡唑并七元氧 杂环类化合物及其合成方法。
物质在结晶时,由于受温度、溶剂、酸碱度、离子等因素的影响,使分 子或者原子在晶格空间排列不同,从而形成不同的晶体结构,造成药物的多 晶现象,不同的晶型其性状、稳定性、溶解性、生物活性和生物利用度等存 在显著的差异,这是影响药物质量与临床疗效的一个重要因素之一。因此, 探索药物的微观结构以及对应的溶解性和稳定性等性能关系具有非常重要的 意义。
因此,亟需发现并进一步制备含有生物活性的三氟甲基的吡唑基并含氧 七元杂环的新的化合物。
