摘要:
The compound named Histidine-pyridine-histidine (HPH) is an oxygen-activating ligand derived from the structure of bleomycin. We synthesized HPH derivatives, namely HPH-1 to -8, and investigated their antiviral activities against herpes simplex virus type 1. HPH-8 showed potent antiviral activity with an EC50 of 15 mu M, and relatively high cytotoxicity with a CC50 of 37 mu m In contrast, HPH-4 indicated a weaker antiviral activity with an EC50 of 79 mu M, but exhibited a far more less cytotoxicity (CC50 500 mu m). Other HPH derivatives showed no effects against antiviral activities and cytotoxicities. (C) 2007 Elsevier Ltd. All rights reserved.
