photooxidation and was shown to be intermediate in the formation of two products of extensive degradation, C and D. Reaction of 1 with the singlet oxygen analogues 4-methyl-1,2,4-triazoline-3,5-dione (MTAD) and 4-phenyl-1,2,4-triazoline-3,5-dione (PTAD) gave products consistent with a proposed mechanism involving the rearrangement of an initially formed endoperoxide to give A and B from reaction of 1 with singlet

(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.
Nanopatterning the surface with ordered supramolecular architectures of N9-alkylated guanines: STM reveals
STM study of the self-assembly at the solid–liquid interface of substituted guanines exposing in the N9-position alkyl side chains with different lengths revealed the formation of distinct crystalline nanopatterns.
