A series of secondary amines combining monoterpenoid and aminoadamantane moieties
have been synthesized. Their cytotoxic activity against human cancer cells CEM-13, MT-4, and U-937
has been studied for the first time. Most of the obtained compounds exhibited a significant cytotoxic
activity with the median cytotoxic dose (CTD50) ranging from 6 to 84 µM. The most promising results
were obtained for compound 2b which was synthesized from 1-aminoadamantane and (-)-myrtenal and revealed a high
activity against all tumor lines used (CTD50 = 12÷21 µM) along with low toxicity with respect to MDCK cells (CTD50 =
1500 µM). The synthesized amines do not exert the genotoxic effect on cells of the biosensor strain based on recombinant
E. coli cells bearing the pRAC-gfp plasmid.
一系列结合单
萜类和
氨基阿曼坦基团的二级胺已被合成。它们对人癌细胞C
EM-13、
MT-4和U-937的细胞毒性活性首次进行了研究。大多数合成的化合物表现出显著的细胞毒性活性,中位细胞毒性剂量(CTD50)在6至84 µM之间。化合物2b的结果最为突出,它是由1-
氨基阿曼坦和(-)-美尔亭醛合成的,并表现出对所有使用的肿瘤
细胞系的高活性(CTD50 = 12÷21 µM),同时对MDCK细胞的毒性较低(CTD50 = 1500 µM)。合成的胺对基于
重组大肠杆菌细胞(携带pRAC-gfp质粒)的
生物传感器菌株细胞没有诱变毒性作用。
