Paragraph 0345-0347, (2017/04/19)
The present invention relates to a novel 4-isopropylchroman-3-ol compound, a pharmaceutical composition comprising the novel compound as an effective component, and to an intermediate compound useful for synthesizing the compound. When administered to a patient with a drug causing toxicity, the novel 4-isopropylchroman-3-ol compound exhibits efficacy of reducing toxicity of the drug by reducing antagonism regarding a T-type calcium channel and/or activity of cytochrome P450 isozyme.

Six new platinum(II) complexes with 1-H or methyl-2-chloromethyl or acetoxymethyl or 2′-hydroxyethyl- benzimidazole carrier ligands were synthesized and evaluated for their reactivity against model nucleophile I -, cellular uptake, and in vitro antiproliferative activities against the human MCF-7 breast and HeLa cervix cancer cell lines. The effect of the compounds on pBR322 plasmid DNA was studied by gel electrophoretic mobility measurements. Flow cytometric analysis was also carried out to study the effect of representative compounds 1 and 2, bearing 2-chloromethyl or -acetoxymethylbenzimidazole carrier ligands, on the cell cycle distribution of MCF-7 and HeLa cells, respectively. In general, it was found that Pt(II) complexes were less cytotoxic than cisplatin and were comparable to carboplatin. The results of the plasmid DNA interaction and the restriction studies suggest that changing the chemical structure of the benzimidazole ligands may modulate DNA binding mode and the sequence selectivity. Compounds 1 and 2 had no significant effect on the cell cycle profile of the cells used. However, compound 2 induced a significant increase in the SubG1 cell population at a concentration of 20 μM.
