A series of eight amino derivatives (3a–h) from perezone 1 were prepared by nucleophilic addition of bioactive amines v.gr. melatonin, acetyl tryptamine, tryptophan and other amino acids esters (valine, leucine and methionine). Their structures were elucidated by spectroscopy data. The cytotoxic evaluation against four human tumor cell lines PC-3, K-562, HCT-15 and SKLU-1 was performed as well as the
通过亲核添加生物活性胺v.gr,制备了来自perezone 1的一系列八个氨基衍生物(3a – h)。褪黑素,乙酰基色胺,色氨酸和其他氨基酸酯(缬氨酸,亮氨酸和蛋氨酸)。通过光谱数据阐明了它们的结构。进行了针对四种人类肿瘤细胞系PC-3,K-562,HCT-15和SKLU-1的细胞毒性评估,以及针对抗氧化活性的TBARS分析。结果表明1及其异构体4对所有细胞系均具有高活性,4对PC-3和HCT-15的效力是1的两倍。导数3a(IC50 = 7.5±0.3μM)对HCT-15的活性比1高,而对K-562有3h选择性,IC 50 = 4.5±0.4μM。TBARS分析表明,IC 50 = 5.564±0.24μM的3c是有效的抗氧化剂,与α-生育酚相比,效果更好,而且比前体分子1更有活性。
