extremely potent triazole inhibitors with K(I) values down to 20 pM, compared to a K(D) value of 0.35 microM for TPP. This triazole scaffold was used for further investigation and six analogues containing mimics of the pyrophosphate group were synthesised and tested for inhibition of PDC. Several effective analogues were found with K(I) values down to around 1 nM.
合成了硫胺素焦磷酸盐(TPP)的新型基于三唑的焦磷酸盐类似物,并测试了其对运动发酵单胞菌(Zymomonas mobilis)丙酮酸脱羧酶(PDC)的抑制作用。在有效的两步操作中,将硫胺素的噻唑鎓环替换为三唑。然后,焦磷酸化作用可制得非常有效的三唑抑制剂,其K(I)值低至20 pM,而TPP的K(D)值为0.35 microM。该三唑支架用于进一步研究,合成了六种含有焦磷酸盐基团模拟物的类似物,并测试了其对PDC的抑制作用。发现了几种有效的类似物,其K(I)值低至约1 nM。
