development of new drugs urgent. To achieve this goal, the integration of kinetic and DSF assays against parasitic validated targets, along with phenotypic assays, can help the identification and optimization of bioactive compounds. Pteridine reductase 1 (PTR1), a validated target in Leishmania sp., is responsible for the reduction of folate and biopterin to tetrahydrofolate and tetrahydrobiopterin, respectively
利什曼病每年造成约65,000人死亡。尽管有死亡率数据,但可用于治疗患者的药物不足,并且除了严重的不良反应外,还具有中等的治疗功效,这使得开发新药物变得迫在眉睫。为了实现此目标,针对寄生虫验证目标的动力学和DSF分析以及表型分析的集成可以帮助鉴定和优化生物活性化合物。蝶呤还原酶1(PTR1)是利什曼原虫(Leishmania sp。)中经过验证的靶标,负责将叶酸和生物蝶呤分别还原为四氢叶酸和四氢生物蝶呤,这两者对于细胞生长都是必不可少的。除了体外评估16种噻唑烷-2,4-二酮衍生物对利什曼原虫主要PTR1(Lm PTR1),使用差示扫描荧光法(ThermoFluor®),采用表型分析评估化合物对巴西利什曼原虫(MHOM / BR / 75 / M2903)和婴儿利什曼原虫(MHOM / BR / 74 / PP75)的作用)前鞭毛虫的生存能力。ThermoFluor®结果表明,噻唑烷-2,
