Выявлено, что энергией связывания (docking score, Ebind, ккал/мол) менее –7,5 с колоколизацией карбонильных групп на расстоянии не более 0,4 нм от атомов азота боковой цепи остатков аргинина белков коронавируса. β-Дикетоны 6-гингердион (код структуры по базе данных Pubchem CID162952), 8-гингердион (CID14440537), тетрагидрокуркумин (CID124072), а также α-дикетон валлитаксан E (CID132967478) обладали такими свойствами.

It has been established that values for energy of binding (docking score, Ebind, kcal/mol) less than –7.5 and for distances of ligands’ carbonyl groups to side chain nitrogens of arginine residues of some coronaviral enzymes within 0.4 nm have been true for β-diketones 6-gingerdione (Pubchem code CID162952), 8-gingerdione (CID14440537), tetrahydrocurcumine (CID124072) as well as α-diketone wallitaxane E (CID132967478).
