  • 毒性总结
人们认为,硫胺素对内皮细胞的作用机制与通过重新定向糖酵解流减少细胞内蛋白质糖基化有关。硫胺素主要是维生素的运输形式,而活性形式是磷酸化的硫胺素衍生物。已知的天然硫胺素磷酸衍生物有五种:硫胺素一磷酸(ThMP)、硫胺素二磷酸(ThDP),有时也称为硫胺素焦磷酸(TPP)、硫胺素三磷酸(ThTP)以及最近发现的腺苷硫胺素三磷酸(AThTP)和腺苷硫胺素二磷酸。每种衍生物都有其独特的功能,然而,大多数作为辅酶参与其中。
It is thought that the mechanism of action of thiamine on endothelial cells is related to a reduction in intracellular protein glycation by redirecting the glycolytic flux. Thiamine is mainly the transport form of the vitamin, while the active forms are phosphorylated thiamine derivatives. There are five known natural thiamine phosphate derivatives: thiamine monophosphate (ThMP), thiamine diphosphate (ThDP), also sometimes called thiamine pyrophosphate (TPP), thiamine triphosphate (ThTP), and the recently discovered adenosine thiamine triphosphate (AThTP), and adenosine thiamine diphosphate. Each derivative has unique functions, however, most are involved as coenzymes.

制备方法与用途

简介

盐酸硫胺素(维生素B1盐酸盐)为白色至黄白色的细小结晶或结晶性粉末,具有米糠似的特异气味,味苦。该物质易吸湿,在空气中迅速吸收约4%的水分。干燥品每克可溶于1毫升水或100毫升乙醇中,并能溶解于甘油而不溶于乙醚和苯。熔点约为248℃(有分解)。在酸性条件下,盐酸硫胺素对热相对稳定,在pH3时即使进行高压蒸煮至140℃、1小时,其破坏也较少。

    The invention provides inhibitors of a sterol C14-demethylase, a new series of 4- aminopyridyl-based lead inhibitors targeting Trypanosoma cruzi CYP51 (TcCYP51) developed using structure-based drug design as well as structure -property relationship (SPR) analyses. The screening hit starting point, LP 10 (KD < 42 nM; EC50 of 0.65 μΜ), has been optimized to give the potential leads that have low nanomolar binding affinity to TcCYP51 and significant activity against T. cruzi amastigotes cultured in human myoblasts. Many of the optimized compounds have improved microsome stability, and most are selective against the T. cruzi CYP51 relative to human CYPs 1A2, 2D6 and 3A4 (<50% inhibition at 1 μΜ). A rationale for the improvement of microsome stability and selectivity of inhibitors against human metabolic CYP enzymes is presented. In addition, the binding mode of several compounds of the invention with the T. brucei CYP51 (TbCYP51) ortholog has been characterized by x-ray structure analysis. Orally active compounds and their cyclodextrin complexes have been shown to be effective against Chagas-infected mice.
    该发明提供了一种甾醇C14-去甲基酶的抑制剂,这是一种新系列基于4-氨基吡啶的首选抑制剂,通过基于结构的药物设计以及结构-性质关系(SPR)分析来瞄准Trypanosoma cruzi CYP51(TcCYP51)而开发的。筛选起始点LP 10(KD < 42 nM;EC50为0.65 μΜ)已经经过优化,产生了具有低纳摩尔级别结合亲和力和对在人类肌细胞培养的T. cruzi游离体的显著活性的潜在首选抑制剂。许多经过优化的化合物具有改善的微粒体稳定性,大多数相对于人类CYPs 1A2、2D6和3A4对T. cruzi CYP51具有选择性(在1 μΜ下<50%的抑制)。提出了改善微粒体稳定性和抑制剂对人类代谢CYP酶的选择性的理由。此外,通过X射线结构分析表征了该发明的几种化合物与T. brucei CYP51(TbCYP51)同源物的结合方式。口服活性化合物及其环糊精复合物已被证明对克氏病感染的小鼠有效。
