The intramolecular hydrogen transfer (IHT) of Hypomycin B (HMB), a novel type of perylenequinonoid photosensitizer (PQP), and of its analogue have been investigated by using quantum chemistry method. The relationship between IHT and its photosensitive activity is discussed.
PQP, a new type of photosensitizer, has attracted more and more attention recently because of their light-induced antiviral (especially anti-HIV) and antitumor activity. The study on structure-activity relationship indicated t...
