Abstract:
A new class of hydrogen sulfide (H(2)S)-donating hybrids combined with pharmacologically active compounds is presented in this article. The pharmacological profiles of some hybrid lead compounds in the areas of inflammation, H(2)S-donating diclofenac (ACS 15); cardiovascular, H(2)S-donating aspirin (ACS 14); urology, H(2)S-donating sildenafil (ACS 6); and neurodegenerative, H(2)S-donating latanoprost (ACS 67) for glaucoma treatment and H(2)S-donating levodopa (ACS 84) for Parkinson's disease, are described. The new H(2)S-releasing hybrids demonstrate remarkable improvement in activity and tolerability as compared with the related parent compounds, suggesting an active pharmacological role for H(2)S. Finally the mechanism(s) of action of glutathione-dependent and independent, and of gas (H(2)S) release (spontaneous or enzymatic) and its implications for clinical pharmacology perspectives will be also discussed.

Hydrogen Bonds Control the World!
Because hydrogen has very weak electronegativity when it binds with a strongly electronegative atom, such as oxygen or nitrogen, electrons in the bond are unequally shared.
Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
