Described herein are compounds, methods of making such compounds, pharmaceutical compositions and medicaments containing such compounds, and methods of using such compounds to treat or prevent diseases or disorders associated with a defect in glyoxylate metabolism, for example a disease or disorder associated with the enzyme glycolate oxidase (GO) or alterations in oxalate metabolism. Such diseases or disorders include, for example, disorders of glyoxylate metabolism, including primary hyperoxaluria, that are associated with production of excessive amounts of oxalate.

It was found that the compounds having the general formula RCH(X)-C≡C-R'gave thiazole derivatives by reaction with thiourea. The relationship between the structure of thiazoles and substituent groups was clarified as follows : (1) When R=R'=Ph, 2-amino-4-benzyl-5-phenylthiazole (IId) is obtained, (2) When R=alkyl, R'=H, two kinds of thiazoles are obtained ; and (3) when R=R'=alkyl, thiazole derivative is not obtained. Similarly, propargyl bromide and phenylpropargyl bromide, when reacted with ammonium dithiocarbamate, afforded 2-mercapto-4-methylthiazole (XX) and 2-mercapto-4-benzylthiazole (XXIII), respectively. Further, 2-amino-4-methylimidazole (XXV) was obtained from guanidine and propargyl bromide.
ring within pocket A of the enzyme. On this basis, chemical modifications were proposed to increase inhibition activity. Synthetic routes had to be adapted and optimized to yield the desired substituted 4- and 5-arylthiazolinethiones. Their biological evaluation shows that 5-aryl regioisomers are systematically less potent than the corresponding 4-aryl analogs. Substitution on the phenyl ring does not

In vivo bioassay results showed that eight T3SSinhibitors could reduce bacterialleafblight and bacterialleaf streak symptoms on rice, significantly.
水稻黄单胞菌(Xanthomonas oryzae)造成的细菌性叶枯病(BLB)被认为是水稻最具破坏性的疾病。杀菌剂的使用是控制这种破坏性疾病的最广泛使用的传统方法之一。过度使用和重复使用相同的杀菌剂也成为产生抗药性的原因。寻找新的抗微生物剂的广泛使用的方法通常将细菌毒力因子作为目标,而不影响细菌的生长。III型分泌系统(T3SS)是一种蛋白质附件,在大多数革兰氏阴性细菌中被认为具有必需的毒力因子。由于保守的构建,T3SS被认为是新的抗菌药物泛滥的重要标志。为了寻找新的T3SS抑制剂,设计和合成了另一系列的1,3-噻唑衍生物。通过1 H NMR,13 C NMR,MS和元素分析对它们的结构进行了表征和确认。所有标题化合物均显着抑制hpa1基因的启动子活性。他们中的八个显示出比我们以前的T3SS抑制剂TS006(邻香豆酸,OCA)更好的抑制作用。用八种化合物处理Xoo可以显着降低HR,而不会影响细菌的生长。一些代表性基因(hrp
