Two diastereomers of methylpheophorbide a 13(2)-N-n-octyl-N-(2-hydroxy-3-isobornyl-5-methylbenzyl)amide were obtained from (+)- and (-)-enantiomers of 2-isobornyl-4-methylphenol. Evaluation of membrane protective and antioxidant activity of individual diastereomers on the model of H2O2-induced hemolysis of blood erythrocytes showed that the stereochemistry of isobornyl substituent in the synthesized conjugates has no effect on their biological activity.
