Novel 1H-pyrazolo[3,4-b]quinoxalines (flavazoles) 14, 15 and 1-aryl-3-quinoxalinyl-1,2,4-triazole 17 were synthesized from the ester 11 via various hydrazones 12, 13 and 16. In the antibacterial screening test of compounds 12–17, compound 14 showed a relatively high antibacterial activity, wherein the MIC value was 25 μg/ml against Bacillus licheniformis KTCC 21425 and Cellulomonas sp. and 50 μg/ml
新型的1 H-吡唑并[3,4- b ]喹喔啉(flavazoles)14、15和1-芳基-3-喹喔啉基-1,2,4-三唑17是由酯11 经由各种,12、13和16合成的。在化合物12-17的抗菌筛选试验中,化合物14表现出相对较高的抗菌活性,其中针对地衣芽孢杆菌KTCC 21425和Cellulomonas sp。的MIC值为25μg/ ml 。和50μg/ ml的鼠伤寒沙门氏菌KCTC 1925和产黄杆菌。
