drug-resistant tuberculosis (TB), has been confirmed through the first synthesis and biochemical characterization of its active metabolite 7. The synthesis features the coupling of N2-acetyl-6-formylpterin obtained from the degradation of folic acid and appropriately functionalized arylamines to form Schiff bases. The sequential chemoselective reduction of the imine and pterin ring led to the formation
对甲氨基水杨酸(PAS),一种用于治疗抗药性结核病(TB)的药物的作用机理已通过其活性代谢物7的首次合成和生化表征得到了证实。该合成的特征在于由叶酸和适当官能化的芳基胺降解形成的席夫碱的降解而获得的N 2-乙酰基-6-甲酰基蝶呤的偶联。亚胺和蝶呤环的顺序化学选择性还原导致形成二氢叶酸类似物7和另外两个二氢蝶呤类物质。
