Abstract:

The inclusion complexes of the neurotransmitters, namely (±) epinephrine hydrochloride, dopamine hydrochloride, and tyramine hydrochloride in an aqueous medium, were studied physicochemically and spectroscopically. These rendered systems of drug delivery with the potential to ensure delivery to desired targets. The stoichiometry of the 1:1 ratio of host-guest binding was established using Job plots. Conductimetric studies gained an understanding of inclusion as a process. Furthermore, 1H NMR was used to characterize the inclusions, and the Benesi Hildebrand equation was applied to obtain the a

Abstract:

The binding interaction of 2-methoxy-5-fluoro phenyl boronic acid with various sugars like dextrose, arabinose, xylose, sucrose, and lactose is investigated in aqueous medium at pH 7.4 using the fluorescence spectroscopic method. Fluorescence intensity is reduced upon addition of sugars. The change in the intensity is attributed to breaking of intramolecular hydrogen bonding and to the lesser stability of boronic ester. Data are analyzed using the Benesi–Hildebrand equation and Lineweaver–Burk equation. The estimated binding constants are greater in mono sugars arabinose and xylose. The fact t

The spectrum of the CTC showed multiple charge transfer bands with a major peak at 843 nm. The Plackett–Burman design (PBD) was used to investigate the process variables with the objective being set to obtaining the maximum absorbance and thus sensitivity. Four variables, three of which were numerical (temperature—Temp; reagent volume—RV; reaction time—RT) and one non-numerical (diluting solvent—DS), were studied. The maximum absorbance was achieved using a factorial ble
