Crystallographic and computational studies on 4-phenyl-N-(β-D- glucopyranosyl)-1H-1,2, 3-triazole-1-acetamide, an inhibitor of glycogen phosphorylase: Comparison with α-D-glucose, N-acetyl-β-D- glucopyranosylamine and N-benzoyl-N′-β-D-glucopyranosyl urea binding
(2008)4-Phenyl-N-(β-D-glucopyranosyl)-1H-1,2,3-triazole-1-acetamide (glucosyltriazolylacetamide) has been studied in kinetic and crystallographic experiments with glycogen phosphorylase b (GPb), in an effort to utilize its ...

Detection of the His-heme Fe2+-NO species in the reduction of NO to N2O by ba3-oxidase from thermus thermophilus
(2005)Reaction pathways in the enzymatic formation and cleavage of the N-N and N-O bonds, respectively, are difficult to verify without the structure of the intermediates, but we now have such information on the heme a3 2+-NO ...

A new [2 + 2] functionalization of C60 with alkyl-substituted 1,3- butadienes: A mechanistic approach. Stereochemistry and isotope effects
(1998)The stereochemistry and secondary isotope effects of the [2 + 2] photocycloaddition of trans,trans- (7), cis,cis- (8), and cis,trans-2,4- hexadiene (9), 2,5-dimethyl-2,4-hexadiene (1), and its deuterated analogues 1-d1, ...

Phenyl radical, cation, and anion. The triplet-singlet gap and higher excited states of the phenyl cation
(1997)High-level ab initio molecular orbital calculations have been carried out for the phenyl cation (1), the phenyl radical (2), and the phenyl anion (3). Our best estimate for the heat of formation (ΔH(f298)) of the phenyl ...

Protein dynamics and electron transfer: Electronic decoherence and non-Condon effects
(2005)We compute the autocorrelation function of the donor-acceptor tunneling matrix element 〈TDA(t)TDA(0)〉 for six Ru-azurin derivatives. Comparison of this decay time to the decay time of the time-dependent Franck-Condon factor ...

Substitution chemistry of 3,5-dichloro-4H-1,2,6-thiadiazine 4,4-ketals
(2016)The reactivity of 3,5-dichloro-4H-1,2,6-thiadiazine 4,4-ketals towards nucleophilic substitution or palladium-catalyzed C–C coupling at the C-3/5 positions led to seven new 3,5-disubstituted 4H-1,2,6-thiadiazine ethylene ...
