Abstract
U svrhu korištenja porfirinskih derivata u fotodinamičkoj terapiji sintetski je pripravljen 152-konjugat klorina e6 i 2-(2-piridil)etilamina. U ovisnosti o reakcijskim uvjetima i reagensima korištenim za peptidno vezanje, nastaju različite smjese u kojima dominira 152-konjugat, u odnosu na 152,173-biskonjugat. Reakcijski mehanizam njihova nastanka i reaktivnosti klorina e6 su diskutirani. Optimizacija reakcije dobivanja 131,152-anhidrida klorina e6 nije dovela do njegove priprave u čistom obliku pogodnom za korištenje za konjugaciju s aminima. Nadalje je pokazano kako direktna 152-konjugacija klorina e6 i triptamina peptidnim vezanjem dovodi do djelomičnog stvaranja produkta. Peptidno vezanje je također korišteno za pripravu novog 131-konjugata klorina e6 i triptofana a korištenjem reagensa za peptidno vezanje. Struktura novopripravljenog spoja je okarakterizirana 1D i 2D NMR (COSY i NOESY), UV/VIS i IR spektroskopijom, te masenom spektrometrijom. Analogna reakcija sa nikotinskom kiselinom nije bila uspješna.
Abstract (english)
For the purpose of use of porphyrin derivatives in photodynamic therapy, new 152-conjugate of chlorin e6 and 2-(2-pyridyl)ethylamine was prepared. Depending on reaction conditions and reagents used in peptide coupling, different mixtures were synthesized, with major product the 152-conjugate. In this master thesis reaction mechanism and reactivity of chlorine e6 is discussed. Optimization of synthesis of 131,152-chlorine e6 anhydride did not lead to its pure state appropriate for amine conjugation. Furthermore is shown that direct conjugation of 152-chlorine e6 and tryptamine by peptide coupling leads to partial product synthesis. Peptide coupling was also used for the preparation of new 131-chlorine e6 conjugate and tryptophan with application of peptide coupling reagents. New compound structure was characterized by 1D and 2D NMR (COSY and NOESY), UV/VIS and IR spectroscopy and also by mass spectrometry. Analogous reaction with nicotic acid was not successful.
