Solvent effects on the fluorescence quenching of tryptophan by amides via electron transfer. Experimental and computational studies.

J. Phys. Chem. B 113 , 2572-2577, (2009)

Hybrid quantum mechanical/molecular mechanics (QM-MM) calculations [Callis and Liu, J. Phys. Chem. B 2004, 108, 4248-4259] make a strong case that the large variation in tryptophan (Trp) fluorescence ...

L-tryptophan ethyl ester dilates small mesenteric arteries by inhibition of voltage-operated calcium channels in smooth muscle.

Br. J. Pharmacol. 166(1) , 232-42, (2012)

L-tryptophan (L-W) is a precursor of the vasoconstrictor, 5-HT. However, acute administration of L-W ethyl ester (L-Wee) lowered blood pressure. The mechanism of action is unknown. This study compares...

[pH dependence of tryptophan ethyl ester hydrolysis].

Biokhimiia 45(5) , 829-34, (1980)

The dependence of the rate of spontaneous hydrolysis of tryptophan ethyl ester within a wide range of pH (4,6-10,3) was studied. This dependence was found to differ from other dependences, i.e. within...
