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.

The present invention provides N-aryl or N-alkyl guanide and biguanide containing compounds having the structure X. or the structure XI. These compounds may be synthesized by the addition of the respective guanide, biguanide or phenylguanide groups to polyamines containing primary and/or secondary amines. The present invention includes methods of using these compounds for the treatment and/or prevention of bacterial infection, HIV infection, and cancer and for the promotion of stem cell mobilization, wound healing, hematopoiesis, and skin rejuvenation.
