the α oxidation of saturated, unsaturated, and heteroatom-containing (oxygen, sulfur) carboxylic acids 1 by the enzyme extract of peas (Pisum sativum) indicate that this biotransformation proceeds highly enantioselectively. For the first time, the synthesis of optically pure 2-hydroxy acids 2 has been achieved on the semipreparative scale (1 mmol) by α hydroxylation of long-chain carboxylic acids with
Provided herein are various oxa acids having respective molecular weights and hydrophile-lipophile balances both different from each other. A compound having a structure represented by the following formula (1)

The present invention discloses amphiphilic 1,4-dihydropyridine derivatives useful for the preparation of a composition for delivering nucleotide containing compounds into a target cell and/or its nucleus. Said composition comprises 1,4-dihydropyridine derivatives having a good DNA condensing capacity and capability of self-association. Also disclosed are composition comprising said derivatives complexed with nucleotide containing compounds as well methods for the producing of said complexes. The invention is also related to the use of said 1,4-dihydropyridine derivatives for manufacturing systems for delivering nucleotide containing compounds useful in gene therapy and DNA vaccination.
