Abstract
Antiviral properties of natural brassinosteroids of the campestane, ergostane, and stigmastane series (6-ketones and B-lactones) and their (22S,23S)-analogs were studied using the seasonal human respiratory alpha-coronavirus 229E (HCoV-229E) as an example. The presence of anticoronavirus properties was shown for a number of studied compounds. In general, 6-ketones were more active than B-lactones. The maximum inhibitory effect (EC50 21.1 µM) in relation to the reproduction of HCoV-229E was noted for (22S,23S)-epicastasterone.
