Synthesis of a New Class of β -Carbonyl Selenides Functionalized with Ester Groups with Antioxidant and Anticancer Properties-Part II.

A series of phenyl β -carbonyl selenides with o-ester functionality substituted on the oxygen atom with chiral and achiral alkyl groups was synthesized. All compounds are the first examples of this type of organoselenium derivatives with an ester substituent in the ortho position. The obtained derivatives were tested as antioxidants and anticancer agents to see the influence of an ester functionality on the bioactivity of β -carbonyl selenides by replacing the o -amide group with an o -ester group. The best results as an antioxidant agent were observed for O -((1 R ,2 S ,5 R )-(-)-2-isopropyl-5-methylcyclohexyl)-2-((2-oxopropyl)selanyl)benzoate. The most cytotoxic derivative against breast cancer MCF-7 cell lines was O -(methyl)-2-((2-oxopropyl)selanyl)benzoate and against human promyelocytic leukemia HL-60 was O -(2-pentyl)-2-((2-oxopropyl)selanyl)benzoate.
