BAY-57-1293

BAY 57-1293 represents a new class of potent inhibitors of herpes simplex virus (HSV) that target the virus helicase primase complex.IC50 Value: 20 nM (HSV-1) [1]Target: HSVin vitro: BAY 57-1293 is nearly two orders of magnitude more potent than acyclovirin vitro and the superiority was even more prominent when the viral load was increased (BAY 57-1293 IC50 = 12 nM, 20 nM and 50 nM; acyclovir IC50 = 1uM, 3M and 10 50 uM at a multiplicity of infection (m.o.i.) of 0.0025, 0.02 and 0.2, res
Pritelivir has been used in trials studying the prevention of HSV-2 and Genital Herpes.|Pritelivir is a thiazolylamide and helicase-primase enzyme inhibitor that is active against herpes simplex virus types 1 and 2 (HSV-1 and HSV-2). Pritelivir inhibits the helicase-primase complex and prevents helicase or primase catalytic cycling of viral DNA, which interferes with DNA replication and growth. This agent does not require activation by HSV thymidine kinase and has a longer plasma half-life than nucleoside analogues.
