Isopulegol, an insoluble in water and highly volatile compound, due to its neuroactive properties is a potentially important agent for medical applications. Formation of "host-guest" molecular complexes with cyclodextrins would lead to the increase of its water solubility and bioavailability.

Despite of advancements in dosage form design and use of multifunctional excipients, improvement in dissolution characteristics of molecules like Telmisartan (TEL) having exceedingly pH dependent and poor solubility profile is still challenging. The present research work explores an innovative particle

Methoxyethylamine monosubstituted β-cyclodextrin, mono-6(A)-(2-methoxyethyl-1-ammonium)-6(A)-β-cyclodextrin chloride (MEtAMCD), is synthesized and analytically characterized. Bearing a methoxy group in cyclodextrin rim, MEtAMCD exhibits outstanding enantioselectivities toward ampholytic and acidic racemates in capillary electrophoresis. Driven by inclusion complexation, electrostatic interactions and/or hydrogen bonding, the

This work revealed that β-cyclodextrin was attached onto the surface of TiO(2) predominately by its secondary ring side, which caused paradoxical functions of β-cyclodextrin in the photodegradation of the four bisphenols. The equilibrium between the guest adsorbed through β-cyclodextrin onto
