Oxidation of 1-aryltetrazole-5-thiols afforded bis(1-aryltetrazol-5-yl) disulfides. The compounds were tested for antimycobacterial activity against Mycobacterium tuberculosis, M. kansasii, M. avium and M. fortuitum. In the case of M. tuberculosis, the logarithm of minimum inhibitory concentration showed a parabolic dependence on hydrophobic substituent constants. Although the compounds exhibited low to medium activity, the most active derivative, bis(4-chlorophenyltetrazol-5-yl) disulfide (III) was more effective against atypical strains than are the commercial tuberculostatics used as standards.
1-芳基四唑-5-硫醇的氧化生成了双(1-芳基四唑-5-基)二硫化物。这些化合物被用于测试其抗结核分枝杆菌活性,包括结核分枝杆菌、堪萨斯分枝杆菌、非结核分枝杆菌和偶发分枝杆菌。在结核分枝杆菌中,最小抑制浓度的对数值显示出与疏水取代基常数的抛物线依赖关系。尽管这些化合物的活性较低至中等,但最活跃的衍生物双(4-氯苯基四唑-5-基)二硫化物(III)比作为标准的商业抗结核药物对非典型菌株更有效。
