abstract = {Ubiquitous in citrus plants, Hesperidin and Hesperetin
flavanones possess several biological functions, including
antiviral activity. Arbovirus infections pose an
ever-increasing threat to global healthcare systems. Among
the severe arboviral infections currently known are those
caused by members of the Flavivirus genus, for example,
Dengue Virus—DENV, Yellow Fever Virus—YFV, and West Nile
Virus—WNV. In this study, we characterize the inhibitory
effect of Hesperidin and Hesperetin against DENV2, YFV, and
WNV NS2B/NS3 proteases. We report the noncompetitive
inhibition of the NS2B/NS3pro by the two bioflavonoids with
half maximal inhibitory concentration (IC50) values <5 µM
for HST and <70 µM for HSD. The determined dissociation
constants (KD) of both flavonoids is significantly below the
threshold value of 30 µM. Our findings demonstrate that a
new generation of anti-flavivirus drugs could be developed
based on selective optimization of both molecules.},
