showed significant anticancer activity against Hela cervix cell line with IC50 of 0.736 μmol and 4a showed significant activity against breast cancer cell line. The antibacterial activity of the tested compounds was also found to be superior to that of piperine. The approach is novel as the abundantly available natural product piperine is utilized as precursor for the synthesis of new potential antimicrobial
通过将胡椒酸与不同氨基酸和取代的苯胺缩合,合成了一系列胡椒碱类似物。评估了合成的化合物(4a - 4e)对人类癌细胞系(MCF-7,乳腺癌细胞和Hela宫颈细胞系)的抗癌活性以及对人类病原体(大肠杆菌,肺炎克雷伯菌,沙门氏菌)的抗菌活性,痢疾志贺菌,枯草芽孢杆菌,金黄色葡萄球菌,铜绿假单胞菌)。在所有测试的人类癌细胞系中,合成化合物的功效均优于胡椒碱。在测试的缀合物中,4c显示出对Hela宫颈细胞系的显着抗癌活性,IC 50为0.736μmol,4a显示出对乳腺癌细胞系的显着活性。还发现测试化合物的抗菌活性优于胡椒碱。该方法是新颖的,因为大量可用的天然产物胡椒碱被用作合成新的潜在抗微生物剂和抗癌剂的前体。
