This is invermectin - putting it online in case it happens to be on the shelves at Enamine. There's a (pretty dubious) suggestion from a computational study that it might bind to Mpro - which is worth us testing, though only (!!) if it's trivial to feed into our test cascade.
Found the study here: https://c19ivermectin.com/, it's a chemrxiv preprint: Francés-Monerris et al., ChemRxiv, doi:10.26434/chemrxiv.12782258.v1 If they'd stuck to presenting their numbers it'd have been fine, but they just couldn't resist stating conclusions, which is duly hackle-raising.
