2-g]chromenes (7a–c), were synthesized and evaluated for their antitubercular activities against Mycobacterium tuberculosis H37RV, and cytotoxicity (CC50) in the VERO cell MABA assay. The results indicate that the furanochromene series of compounds (3a–g and 4a–d) showed only weak to moderate antitubercular activity. However, the pyranochromene analog 7b showed good antitubercular activity (IC90: 5.9 μg/mL) and
2-苯甲酰基-3-甲基-5-氧代-5 H-呋喃[3,2- g ]色烯-6-甲醛的一系列新的巴比妥酸酯和硫代巴比妥酸酯类似物(分别为3a – g和4a – d)和6合成了-甲基-4,8-二氧杂-4-3,8-二氢吡喃[3,2- g ]色酮(7a – c),并评估了其对结核分枝杆菌H37RV的抗结核活性以及在VERO中的细胞毒性(CC 50)细胞MABA测定。结果表明,呋喃并二烯系列化合物(3a - g和4a - d)仅显示弱至中度的抗结核活性。然而,吡喃并二氢吡啶类似物7b显示出良好的抗结核活性(IC 90:5.9μg/ mL)和细胞毒性(CC 50:14.27μg/ mL)。7b的抗结核活性优于抗结核药物吡嗪酰胺(PZA; IC 90:> 20μg/ mL)。类似物7b被认为是后续结构优化的先导化合物。
