Owing to the pharmacological potential of ATRA (all trans-retinoic acid), a series of retinamides and a 1-(retinoyl)-1,3-dicyclohexylurea compound were prepared by reacting ATRA with long chain alkyl or alkenyl fatty amines by using a 4-demethylaminopyridine (DMAP)-catalyzed N,N¢-dicyclohexylcarbodiimide (DCC) coupling. The successful synthesis of the target compounds was demonstrated using a range of spectroscopic techniques. The cytotoxicity of the compounds was measured along with their ability to induce cell cycle arrest and apoptosis in human cancer cell lines MCF-7 (breast cancer) and HepG2 (liver cancer) and normal human cell line HEK293 (embryonic kidney). The results of cytotoxicity and flow cytometry data showed that the compounds had a moderate to strong effect against MCF-7 and HepG2 cells and were less toxic to HEK293 cells. N-oleyl-retinamide was found to be the most potent anticancer agent and was more effective against MCF-7 cells than HepG2 cells.

脲化合物。一系列光谱技术证明了目标化合物的成功合成。在人类癌细胞 MCF-7(乳腺癌)和 HepG2(肝癌)以及正常人细胞 HEK293(胚胎肾脏)中测定了这些化合物的细胞毒性及其诱导细胞周期停滞和凋亡的能力。细胞毒性和流式细胞仪数据结果表明,这些化合物对 MCF-7 和 HepG2 细胞有中等至较强的作用,而对 HEK293 细胞的毒性较低。结果发现,N-油基
视黄醇酰胺是最有效的抗癌剂,对 MCF-7 细胞的作用比对 HepG2 细胞的作用更强。
