Development and butyrylcholinesterase/monoamine oxidase inhibition potential of PVA-Moringa oleifera developed nanofibers

Abstract The objective of the current research was to study the effects of polyvinyl alcohol (PVA) electrospun nanofibers loaded with different concentrations of leaf extract of Moringa oleifera (MO) on butyrylcholinesterase (BuChE), monoamine oxidase A (MAO A) and monoamine oxidase B (MAO B) enzymes. The MO-loaded PVA nanofibers were investigated for their inhibitory effect on BuChE and MAO A & B enzymes. The characterization of the fabricated nanofibers was performed by using SEM, FTIR and XRD. The results showed that increasing the concentration of MO, the enzyme inhibition capability of electrospun nanofibers was greatly (p < 0.05) influenced. This study involved the fabrication of electrospun nanofibers of PVA containing four different concentrations of MO (0%, 0.1%, 0.2% and 0.4%). The SEM micrographs revealed that all the nanofibers were porous, beadless and smooth. At a high concentration of M. oleifera, uniform fibers were obtained. The FTIR results of the fabricated nanofibers revealed that chemical interaction did not take place between M. oleifera and polyvinyl alcohol. The results reveal that with an increase in the concentration of M. oleifera (MO), the enzymes inhibition capability of electrospun nanofibers is greatly influenced. Different concentrations of MO extract were successfully loaded to the MMT-reinforced, glutaraldehyde-cross-linked nanofibers.
