The inhibition of the C-terminal domain of heat shock protein 90 (Hsp90) is emerging as a novel strategy for cancer therapy, therefore the identification of a new class of C-terminal inhibitors is strongly required.

nature and steric hindrance of the substituents, their positions and their orientations towards the heterocyclic ring, determine their effects on the oxidation peak potential. The electron detachment process in this study is also affected by the nature of solvent, which explains the extent of solvation of both neutral THPM and THPṀ + .

The semiconductor-sensitized oxidation of various 1-, 4- and 5-substituted 2-oxo-1,2,3,4-tetrahydropyrimidines was carried out in acetonitrile using TiO2 anatase nanoparticles. The aims of this study were to elucidate the effects of the nature of the substituents on the 1-, 4- and 5-positions of the heterocyclic ring, the type of the photocatalyst and the nature of solvent on the rate of reaction. The proposed electron-transfer mechanism is supported by the experimental results and also by the computational studies. (C) 2012 Elsevier B.V. All rights reserved.
