A series of N-substituted morpholines 2-20 was synthesised by reacting various acid chlorides and alkyl halides with morpholine (1). All of the synthesised compounds 2-20 were screened for their leishmanicidal effects using amphotericin B (IC(50) = 0.24 microg L(-1)) and pentamidine (IC(50) = 2.56 microg mL(-1)) as standards and a structure-activity relationship (SAR) study was established. The compounds 2 (IC(50) = 48 microg mL(-1)), 3 (IC(50) = 30.0 microg mL(-1)), 10 (IC(50) = 41.0 microg mL(-1)), 15 (IC(50) = 33.0 microg mL(-1)), 16 (IC(50) = 35.0 microg mL(-1)) and 20 (IC(50) = 47.0 microg mL(-1)) showed weak leishmanicidal activities.
通过使各种酰氯和卤代烷与吗啉(1)反应,合成了一系列N-取代吗啉2 - 20。以两性霉素B(IC50 = 0.24μg L-1)和喷他脒(IC50 = 2.56μg mL-1)作为标准,对所有合成的化合物2 - 20进行了杀利什曼原虫效果筛选,并建立了构效关系(SAR)研究。化合物2(IC50 = 48μg mL-1)、3(IC50 = 30.0μg mL-1)、10(IC50 = 41.0μg mL-1)、15(IC50 = 33.0μg mL-1)、16(IC50 = 35.0μg mL-1)和20(IC50 = 47.0μg mL-1)显示出较弱的杀利什曼原虫活性。
