Anti-Herpes Simplex Virus Activity of Substituted 1-Hydroxyacridones
摘要:
5-Chloro-1,3-dihydroxyacridone, 1, is a potent and selective inhibitor of Herpes Simplex Virus Type-1 (HSV-1).(1) Substituted 1,3-dihydroxyacridones represent a new class of nonnucleoside HSV-1 inhibitors, and biochemical studies indicate a novel mechanism of action for 1, although the target is not yet defined.(2) With the goal of lead optimization, analogues of 1 were synthesized in an effort to describe the structure-activity relationships between 1 and its hypothetical binding site. Modifications of key functional groups led to the identity of several features of I that were important for activity. In the process, a more expedient and reliable synthesis of 1 and its analogues was developed. Analogues were evaluated against HSV-1 and HSV-2 using a viral plaque-elimination assay for viral inhibition of HSV-1 and HSV-2, and effects on replication of the host cell were also measured in order to assess a therapeutic index (TI) of selectivity. Several new analogues with significant antiviral activity were identified, including 5-methoxy-1,3-dihydroxyacridone (11), which inhibits replication of several HSV-2 strains with a mean ED50 of 0.7 muM and a TI range of 25-60-fold.

A method for preparing an ophthalmic device containing an ultraviolet (UV) blocker is disclosed. The method involves (a) soaking an ophthalmic device in one or more first solvent solutions to swell the ophthalmic device; (b) soaking the swelled ophthalmic device in one or more second solvents solutions comprising a UV blocker to de-swell the ophthalmic device and entrap the UV blocker in the ophthalmic device, wherein the UV blocker is a benzotriazole and (c) sterilizing the de-swelled ophthalmic device.
