13C-nuclear magnetic resonance, mass and elemental analysis data. The antimicrobial activity of these compounds was determined by the serial plate dilution method. The compounds with fluoro-substituted coumarin ring along with the fluoro-substituted phenyl ring, 9q, 9r, and 9s, produced better and potent antimicrobial activity than their corresponding H/chloro/iodo/bromo-substituted analogs with statistically
一系列新颖的3-(2-(5-(2-氯喹啉-3-基)-3-取代的苯基-4,5-二氢-1 H-吡唑-1-基)噻唑-4-基)-6 -H / halo-2 H -chromen-2-ones(9a–9y)通过3-(2-溴乙酰基)-6-H / halo-2 H -chromen-2-one(4a-4e)和5-(2-氯喹啉-3-基)-3-取代的苯基-4,5-二氢-1 H-吡唑-1-碳二酰胺(8a-8e)。这些化合物的结构是根据其红外,1 H核磁共振,13C核磁共振,质量和元素分析数据。这些化合物的抗菌活性通过连续板稀释法确定。具有氟取代的香豆素环以及氟取代的苯环9q,9r和9s的化合物比其相应的H /氯/碘/溴取代的类似物产生更好和有效的抗菌活性,具有统计学意义的结果(p < 0.05)。化合物9q和9r还比标准药物酮康唑对柠檬青霉产生更高的抗真菌活性。但是,这些化合物需要比标准药物氧氟沙星和酮康唑
