4-(Phenylamino)-5-phenyl-7-(5-deoxy-beta-D-ribofuranosyl)pyrrolo[2,3-d]pyrimidine 1 and related compounds known as "diaryltubercidin" analogues are potent inhibitors of adenosine kinase (AK) and are orally active in animal models of pain such as the rat formalin paw model (GP3269 ED50= 6.4 mg/kg). However, the utility of
When mobile-phase salt content is increased, cationic analytes often show increased retention. This effect is generally attributed to chaotropic or ion pairing effects. However, a cation exclusion mechanism could explain the same effects. In this study, experimental conditions were manipulated

A catalytic α-sp(3) C-H oxidation of peptides and glycine amides was achieved under radical cation salt catalysis in the presence of O2, producing a series of substituted quinolines. The scope of this reaction shows good functional group tolerance and high
As a model for mechanistic comparison with peptidyl transfer within the ribosome, the reaction of aqueous glycinamide with N-formylphenylalanine trifluoroethyl ester (fPhe-TFE) represents an improvement over earlier model reactions involving Tris. The acidity of trifluoroethanol (pKa 12.4) resembles that of
A possible reaction mechanism for the dehydration of glycinamide (3) and N,N'-diformylurea (4) yielding hypoxanthine (2) has been investigated. Furthermore, a potential prebiotic route converting hypoxanthine (2) into adenine (1) via phosphate activation followed by substitution reaction with NH3 was
