Several 9-benzyl-N6-cycloalkyl-2-phenyladenines, 9-benzyl-N6-cycloalkyl-2-phenyl-8-azaadenines and 4-cycloalkylamino-1-benzyl-6-phenyl-1H-1,2,3-triazolo[4,5-c]pyridines were prepared and assayed as A1 adenosine receptor ligands. The 1H-1,2,3-triazolo[4,5-c]pyridines were obtained starting from N,N-diethyl-1-benzyl-4-carboxyamido-5-methyl-1H-1,2,3-triazole by lithiation in anhydrous tetrahydrofurane in the presence of benzonitrile. The usual work up afforded the isolation of 1-benzyl-6-phenyl-1H-1,2,3-triazolo[4,5-c]pyridin-4-one

The nature of recessive mutations at the autosomal locus encoding the purine salvage enzyme adenine phosphoribosyl transferase (APRT) was analyzed in a highly malignant human tumor cell line (the colorectal carcinoma line SW620). Mutant strains resistant to the purine analog

The TK6 human B lymphoblastoid cell line contains two easily and widely used selectable markers: the X-linked, hemizygous hprt locus, and the heterozygous tk locus on chromosome 17q. In this study, rare APRT heterozygotes were directly isolated from the TK6

Rodent ultraviolet light (UV)-sensitive mutant cells in complementation groups (CGs) 1 and 4 normally are known for their extraordinary (approximately 80-100 x) sensitivity to mitomycin C (MMC), although some CG1 mutants with reduced MMC sensitivity were previously reported (Stefanini et

The photophysics of 8-azaadenine (8-AA) has been studied with the CASPT2//CASSCF protocol and ANO-L double-ζ basis sets. Stationary equilibrium structures, surface crossings, minimum energy paths, and linear interpolations have been used to study possible mechanisms to populate the lowest triplet
