Influence of diamino acid derivatives of protoporphyrin IX on mouse immunological system: Preliminary results

The results show that all of the diamino acid derivatives of protoporphyrin IX indicate an immunological response when the light is applied. Each of the porphyrin revealed different impact on mice immunological system. The most potent stimulant properties disclosed PP(Phe)2Arg2 derivative for which the highest values of IL-1β, IL-6 and NO2- were noticed. The weakest immunological activation revealed PP(Ser)2Arg2 derivative.
