A series of novel flavone derivatives were designed, synthesized, and evaluated for their H3R inhibitory activity. The results showed that four compounds exhibited significant anti-H3R activity. Moleculardocking experiments indicated that a salt bridge, hydrogen-bonding, and hydrophobic interactions all contributed to interactions between inhibitors and H3R.

A series of novelflavonoid alkaloids were synthesized with different flavonoids and attached nitrogen-containing moieties. These new compounds were screened for inhibitory activity of α-glucosidase, among which compound 23 was found to show the lowest IC50 of 4.13 μM. Kinetic analysis indicates that the synthesized compounds 15 and 23 inhibit the enzyme in a non-competitive model with Ki value of
