All - last week's call for compound designs to the CoV-2 main protease (https://covid.postera.ai/covid) elicited an astonishing response...  (I confess I was quite taken aback.) I just realised I should let this BB know the second call for designs is now open. *Deadline is tomorrow 23:59 PST (April 2nd). *(Apologies for those that weren't following on twitter.)* *Two things: * we're asking for designs especially focusing on covalent inhibitors (read more here https://discuss.postera.ai/t/screening-cascade-fast-track-and-regular-track-...) * the most convincing designs will be fast-tracked by spending more money to cut several weeks off the testing (read more here https://discuss.postera.ai/t/screening-cascade-fast-track-and-regular-track-...) Happy designing! Frank
