Solvents have a profound influence on chemical reactions in solution and have long been used to control their outcome. Such effects are generally considered to be governed by thermodynamics; however, little is known about the steric effects of solvent molecules.

Five water-soluble chitosan derivatives were carried out by quaternizing either iodomethane or N-(3-chloro-2-hydroxypropyl) trimethylammonium chloride (Quat188) as a quaternizing agent under basic condition. The degree of quaternization (DQ) ranged between 28±2% and 90±2%. The antifungal activity was evaluated by using

To explore the possible use of positron emission tomography (PET) probes for imaging of I(2)-imidazoline receptors (I(2)Rs) in peripheral tissues, we labeled two new I(2)R ligands, 2-[2-(o-tolyl)vinyl]-4,5-dihydro-1H-imidazole (K(i) for I(2)Rs, 3.7 nM) and 2-[2-(o-tolyl)ethyl]-4,5-dihydro-1H-imidazole (K(i) for I(2)Rs, 1.7 nM) with
