制备方法与用途

用途

2-氯-5-(三氟甲基)苯甲酸是一种新型治疗糖尿病药物的重要中间体,还可用于合成热休克蛋白诱导剂和非甾体抗炎药。作为重要的医药中间体,它在新药研发中也具有广阔的前景。

制备

称取18.1g(0.1mol)对氯三氟甲基苯和11.6g(0.1mol)四甲基乙二胺,溶解于无水四氢呋喃150ml中。用干冰-丙酮浴将反应混合液降温至-75℃并抽真空氮气保护。

在氮气保护下,抽取叔丁基锂(1.3M正己烷溶液)77.0ml(0.1mol),置于恒压滴液漏斗中。然后缓慢加入上述体系中,滴加时确保反应温度不超过-70℃。滴加完成后,继续搅拌1小时。

将反应液缓慢倾倒在干冰表面,并在干冰挥发后搅拌30分钟。随后用6N盐酸30ml调节pH值至4,继续在5-10℃下搅拌5-6小时,析出浅黄色固体。过滤、水洗,于40℃真空干燥得到21.7g的粗产品。

将21.7g粗产品加入100ml正己烷溶液中,加热回流30分钟后冷却至室温,析出白色结晶型精制产品,最终获得20.61g纯品,收率为92%。

Starting from 2-chloro-N-(S)-phenyl[(2S)-piperidin-2-yl]methyl}-3-(trifluoromethyl)benzamide (2, SSR504734), the introduction of heteroaromatic rings enabled an increase in the GlyT1 inhibitory activity.

    Recent study indicates that DNMT inhibitors and HDAC inhibitors display synergistic effects in certain cancers, therefore, development of molecules targeting both DNMT and HDAC is of therapeutic advantage against these cancers. Based on the structure of DNMT inhibitor NSC-319745 and the pharmacophore characteristics of HDAC inhibitors, a series of hydroxamic acid derivatives of NSC-319745 were designed
    DNA甲基转移酶(DNMT)和组蛋白脱乙酰基酶(HDAC)是抗癌药物开发过程中重要的表观遗传学靶标。最近的研究表明,DNMT抑制剂和HDAC抑制剂在某些癌症中显示出协同作用,因此,靶向DNMT和HDAC的分子的开发对这些癌症具有治疗优势。根据DNMT抑制剂NSC-319745的结构和HDAC抑制剂的药效团特性,设计并合成了一系列NSC-319745异羟肟酸衍生物,作为DNMT和HDAC多功能抑制剂。大多数化合物显示出潜在的DNMT抑制潜能和有效的HDAC抑制活性,尤其是化合物15a表现出比NSC-319745更好的DNMT1抑制潜能,并且抑制HDAC1,HDAC6的IC50值分别为57、17 nM。此外,合成的化合物对人癌细胞K562和U937表现出显着的细胞毒性。进一步的机理研究表明,U937的15a处理可增加组蛋白H3K9和H4K8的乙酰化,促使P16 CpG岛脱甲基并上调P16表达,
