Structure-activity relationships of N2-substituted guanines as inhibitors of HSV1 and HSV2 thymidine kinases
摘要:
A series of N2-phenylguanines was synthesized and tested for inhibition of the thymidine kinases encoded by Herpes simplex viruses type 1 and type 2. Compounds with hydrophobic, electron-attracting groups in the meta position of the phenyl ring such as m-trifluoromethyl (m-CF3PG, IC50 = 0.1 microM) were the most potent inhibitors of both enzymes. Many derivatives were significantly more potent against the type 2 thymidine kinase, and can effectively discriminate between the two enzymes. Among other N2-substituted guanines, alkyl and benzyl derivatives were moderately potent inhibitors, and the type 2 enzyme was again more sensitive than the type 1 enzyme. None of the compounds inhibited the thymidine kinase isolated from the host HeLa cell line, suggesting that members of this class of compounds may be useful nonsubstrate, antiviral compounds for latent herpesvirus infections.

(EN) N2-substituted alkylguanines and N2-substituted phenylguanine compounds which prevent recurrent herpes simplex infections are disclosed. By virtue of their ability to inhibit herpes virus thymidine kinase $i(in vivo), such compounds will prevent, reduce the frequency of, or reduce the severity of recurrent HSV infections in humans.(FR) L'invention concerne des composés d'alkylguanine N2-substituée et de phénylguanine N2-substituée servant à empêcher des infections récurrentes d'herpès simplex. Etant donné leur capacité d'inhibition de la thymidine kinase du virus de l'herpès $i(in vivo), ces composés serviront à empêcher les infections récurrentes par le virus de l'herpès simplex chez l'homme, ou à diminuer leur fréquence et leur gravité.
