Design Rationale:

Chromones have been identified as privileged scaffolds in drug discovery and reported as antivirals in the treatment of HIV (1) Para substitution on the B ring has been reported as required to promote antiplasmodial activity and increase HIV-2 potency (2) Naturally occurring medicinal plant containing chromones have been shown to inhibit SARS-CoV-2 3CLpro activity and hence virus replication in computational screening (3) 1.

Other Notes:

Most of these compounds readily accessible and the others can be simply remade. The synthesis of these compounds is simple and can be easily reproduced to produce a range of analogues (4, 5) 4.
