to > 51.7 μg/mL), for chalcones 8a,d and pyrazolines 10c,d. All compounds were assessed for antibacterial activity against wild type and multidrug resistant gram negative and gram positive bacteria, with MIC values ranging from 31.25 to 500 μg/mL. Additionally, the novel compounds were tested for antifungal and antiparasitic properties. Although these compounds showed mild activity against Candida
从[(7-氯喹啉-4-基)氨基]查耳酮8a的环缩合反应中获得了一系列新的N-取代的2-吡唑啉9a-f,10a-f,11a-f,12a-f和13a-f。 -f与水合肼及其衍生物。美国国家癌症研究所(NCI)选择了包括起始查耳酮在内的14种合成化合物来测试其对60种不同人类癌细胞系的抗癌活性,其中最重要的GI50值范围为0.28至11.7μM(0.13-6.05μg/查耳酮8a,d和吡唑啉10c,d的LC50值范围为2.6至> 100μM(1.2至> 51.7μg/ mL)。评估了所有化合物对野生型和多重耐药革兰氏阴性和革兰氏阳性细菌的抗菌活性,MIC值为31.25至500μg/ mL。此外,测试了这些新型化合物的抗真菌和抗寄生虫特性。尽管这些化合物显示出对白色念珠菌的温和活性,但查耳酮8a和8e显示出对新隐球菌的高活性,MIC50 = 7.8μg/ mL。对于恶性疟原虫活性,2-吡唑啉11b的活性最高,EC50
