(1R,2R)-N1-2-amyl-1,2-diaminocyclohexane, which has an amyl substituent as compared with 1,2-diaminocyclohexane, was used as the carrier group to construct three platinum(II) complexes. MTT assay revealed that the complexes showed decent cytotoxicity against all of the four tested tumor cell lines with the IC50 values ranging from 1.08 to 253.36 μM. Particularly, the IC50 values of 2 against A549 and HCT-116 reached 3.32 and 1.08 μM, respectively, which were much lower than those of cisplatin and oxaliplatin. Flow cytometry demonstrated that 2 inhibited HepG2 cells proliferation and caused cytotoxicity by inducing apoptosis and arresting cells in the G2 phase. Furthermore, agarose gel electrophoresis showed that 2 had the ability to interact with DNA in a manner different from cisplatin and oxaliplatin, indicating the carrier ligand with an alkyl moiety had an influence on the action mode of the complex. 相似文献

Epimeric (1R,2R,6S)-3-methyl-6-(prop-1-en-2-yl)cyclohex-3-ene-1,2-diol derivatives containing a rimantadine residue have been synthesized, and their steric structure has been determined using NOESY technique and DFT quantum chemical calculations. 相似文献

The reaction of dihydroxo(1R,2R-cyclohexanediamine)platinum(II) with (-)-quinic acid gave a water soluble complex, (-)-quinato(1R,2R-cyclohexanediamine)platinum(II). The crystal structure of the complex was determined by X-ray analysis. The data indicate a chelation of the alpha-hydroxycarboxylic acid part of quinic acid to platinum(II). The complex shows moderate antitumor activity against murine leukemia L1210 at high doses (T/C x 100 = 179% at a dose of 200 mg/kg). 相似文献
