  Relationships Between the Chemical Structure of Substances and Their Antimycobacterial Activity Against Atypical Strains. Part 18. 3-Phenyl-2H-1,3-benzoxazine-2,4(3H)-diones and Isosteric 3-Phenylquinazoline-2,4(1H,3H)-diones

  摘要：

  合成了一系列在苯环上取代的3-苯基-2H-1,3-苯并噁嗪-2,4(3H)-二酮2和3-苯基喹唑啉-2,4(1H,3H)-二酮5。目标化合物以及中间体被测试对抗结核分枝杆菌、肯萨斯分枝杆菌和埃维分枝杆菌。氮原子替代氧原子导致抗结核活性下降或丧失。2-[(乙氧羰基)氨基]苯甲酰胺4似乎无活性。水杨酰苯胺1和3-苯基-2H-1,3-苯并噁嗪-2,4(3H)-二酮2对结核分枝杆菌和非结核分枝杆菌表现出显著活性（所有化合物的最小抑制浓度在4-250 μmol/l范围内）。化合物的抗结核活性随着苯基上取代基的电子吸引性和疏水性增加而增加。根据基于向量代数的标准，如余弦系数，分析了化合物的抗结核特性。此外，水杨酰苯胺1对经琼脂扩散法测试的其他微生物也具有活性。

  A series of 3-phenyl-2H-1,3-benzoxazine-2,4(3H)-diones 2 and 3-phenylquinazoline-2,4(1H,3H)-diones 5 substituted on the phenyl rings were synthesized. The target compounds as well as the intermediates were tested against Mycobacterium tuberculosis, M. kansasii, and M. avium. The replacement of the oxygen atom by nitrogen resulted in a decrease or loss of antimycobacterial activity. 2-[(Ethoxycarbonyl)amino]benzanilides 4 appeared to be inactive. Salicylanilides 1 and 3-phenyl-2H-1,3-benzoxazine-2,4(3H)-diones 2 exhibit significant activity against both M. tuberculosis and nontuberculous mycobacteria (the MICs within the range of 4-250 μmol/l for all compounds). The antimycobacterial activity of the compounds increases with increasing both electron-withdrawing properties and hydrophobicity of the substituent(s) on the phenyl moiety. The antimycobacterial profile of the compounds was analyzed according to the criteria based on vector algebra, such as cosine coefficients. Moreover, salicylanilides 1 exhibit activity against other microorganisms tested by the agar diffusion method.
