摘要:
New porphyrin/4-oxoquinoline conjugates were synthesized from the Heck coupling reaction of a beta-brominated porphyrin with 1-allyl-4-oxoquinoline derivatives, followed by demetallation and deprotection affording the promising photosensitizers 9a-e. Singlet oxygen studies have demonstrated that all the porphyrin/4-oxoquinoline conjugates 9a-e were capable of producing cytotoxic species and found to be excellent photosensitizing agents in the inactivation of S. aureus by the antimicrobial photodynamic therapy (aPDT) protocol.
