In present work sulfur amino acid-containing bacteriochlorophyll a residues were obtained. It has been found that the oxidation of free thiol groups in cysteine-containing bacteriopurpurinimide occurs under the action of atmospheric oxygen with the disulfide form formation. In cells this disulfide derivative undergoes monomerization with the participation of reduced form of glutathione. Oxidation of the methionine residue in the conjugate with dipropoxybacteriopurpurinimide results in the stable sulfoxide form. Mechanism for suppressing the antioxidant system of a cell under the action of sulfur-containing bacteriochlorophyll a derivatives is proposed.
