The synthesis of 19 compounds derived from L-serine and analogs of p-substituted cinnamic acid is reported. Oxazolines 9 and oxazoles 10 have high antitubercular activity with Minimum Inhibitory Concentration (MIC) of 0.7812-25.0 µg/mL (3.21-100.3 µM), against two strains of Mycobacterium tuberculosis sensitive to first-line drugs Isoniazid (INH), Rifampicin (RIF), Ethambutol (EMB), Pyrazinamide (PZE)
据报道,合成了19种衍生自L-丝氨酸的化合物和对位肉桂酸的类似物。恶唑啉9和恶唑10具有高抗结核活性,对两种对一线药物异烟肼(INH),利福平(RIF)敏感的结核分枝杆菌菌株的最低抑菌浓度(MIC)为0.7812-25.0 µg / mL(3.21-100.3 µM)。),乙胺丁醇(EMB),吡嗪酰胺(PZE)(H37Rv)和对INH,RIF和EMB有抗药性的临床分离株(G122)。细胞毒性评估表明,恶唑类药物活性低,对VERO细胞系的生存力大于96%。结果表明这些化合物可被视为抗结核治疗的未来替代品。
