Geometry optimisations was carried out using the hybrid functional and basis set: M06-2X/6-31+G(d,p). Our calculations show that all the flavonols investigated are chemically reactive. Their reactivity is greatest in water hence making them suitable drug candidates since this is the ideal medium for drug delivery. The highest negative charge on the oxygen atom of the hydroxyl and high positive charge on the H atom of C5-OH are vital for antioxidant activity. The most reactive species, from reactivity descriptor calculations, is Gossypetin. All the flavonols are active as enzyme inhibitors and moderately active as G-protein-coupled receptors, ion channel modulators and protease inhibitors. The physicochemical properties show the flavonols have good bioavailability. All the compounds agree with Lipinski’s rule of 5, signifying potential use as oral active drugs.AbstractenBioactivity scoresChemical reactivity propertiesDFTFlavonolsSpectroscopyArticleAkintemi, E., Govender, K.
