Electrochemical characterization and estimation of DNA-binding capacity of a series of novel ferrocene derivatives.

The synthesis of a series of methyl 2-alkyl-5-aryl-4-ferrocenoylpyrrolidine-2-carboxylates has been achieved by [3 + 2] dipolar cycloaddition of azomethine ylides to acryloylferrocene. The electrochemical properties of novel products were examined by cyclic voltammetry (CV) and differential pulse voltammetry (DPV). These techniques revealed the quasi-reversible one-electron oxidation process.

Cytotoxic and Antimicrobial Activity of Dehydrozingerone based Cyclopropyl Derivatives.

A small series of 1-acetyl-2-(4-alkoxy-3-methoxyphenyl)cyclopropanes was prepared, starting from dehydrozingerone (4-(4-hydroxy-3-methoxyphenyl)-3-buten-2-one) and its O-alkyl derivatives. Their microbiological activities toward some strains of bacteria and fungi were tested, as well as their in vitro cytotoxic activity against some cancer cell lines (HeLa, LS174 and A549). All synthesized compounds showed significant antimicrobial activity and expressed cytotoxic activity against tested carcinoma cell lines, but they showed no significant influence on normal cell line (MRC5).

Chemistry of spices: bornyl 4-methoxybenzoate from Ferula ovina (Boiss.) Boiss. (Apiaceae) induces hyperalgesia in mice.

Unlabelled: Ferula ovina (Boiss.) Boiss. is a traditional Iranian flavoring agent used as an ingredient of spices and condiments.
