A new paper that identifies some promising anti-Covid-19 treatments ---
"Repurposing Therapeutics for COVID-19: Supercomputer-Based Docking to the SARS-CoV-2 Viral Spike Protein and Viral Spike Protein-Human ACE2 Interface"
Abstract
The novel Wuhan coronavirus (SARS-CoV-2) has been sequenced, and the virus shares substantial similarity with SARS-CoV. Here, using a computational model of the spike protein (S-protein) of SARS-CoV-2 interacting with the human ACE2 receptor, we make use of the world's most powerful supercomputer, SUMMIT, to enact an ensemble docking virtual high-throughput screening campaign and identify small-molecules which bind to either the isolated Viral S-protein at its host receptor region or to the S protein-human ACE2 interface. We hypothesize the identified small-molecules may be repurposed to limit viral recognition of host cells and/or disrupt host-virus interactions. A ranked list of compounds is given that can be tested experimentally.

Table 3 lists the top candidates - some are fairly easy to obtain.
Worth noting is that the readily available flavonoid quercetin (designated as 'quercetol;quercitin') is highly ranked, so is luteolin-monoarabinoside which I believe is found in dark colored berries, perhaps responsible for their alleged anti-viral effects
Some speculation - Furin protease inhibitors are also being investigated to reduce Covid-19 infectivity.
Several flavonoids - baicalein, chrysin, rutin appear to inhibit furin.
