85) were shown by the 3,5-bis-trifluoromethylphenyl amide of 5-tert-butyl-6-chloropyrazine-2-carboxylic acid (2o). The 3-methylphenyl amides of 6-chloro- and 5-tert-butyl-6-chloro-pyrazine-2-carboxylic acid (2d and 2f) exhibited only a poor in vitro antifungal effect (MIC = 31.25-500 μmol·dm-3) against all strains tested, although the latter was the most active antialgal compound (IC50 = 0.063 mmol·dm-3)
6-氯-、5-叔丁基-或 6-氯-5-叔丁基吡嗪-2-甲酰氯与环取代苯胺缩合得到一系列酰胺,在体外测试了它们的抗分枝杆菌、抗真菌和抗真菌作用。光合作用抑制活性。5-叔丁基-6-氯吡嗪-2-羧酸的3,5-双-三氟甲基苯基酰胺对结核分枝杆菌具有最高的抗结核活性(72%抑制)和最高的亲脂性(log P = 6.85)。 2o)。6-氯-和5-叔丁基-6-氯-吡嗪-2-羧酸的3-甲基苯基酰胺(2d和2f)仅表现出较差的体外抗真菌作用(MIC = 31.25-500 μmol·dm- 3) 对抗所有测试的菌株,尽管后者是最活跃的抗藻化合物(IC50 = 0.063 mmol·dm-3)。
