Antioxidant properties, anti- SARS-CoV-2 study, collagenase and elastase inhibition effects, anti-human lung cancer potential of some phenolic compounds

Lung cancer is one of the main reasons for death worldwide. The natural compounds with anti-lung cancer potential are of main interest and are considered a very promising alternative to replace or raise the efficiency of conventional drugs. Diethylstilbestrol, Enterodiol, Enterolactone, Flavokawain A, Flavokawain B, and Flavokawain C compounds showed excellent to good inhibitory activities against studied these enzymes with IC(50) values in ranging between 9.66 ± 1.52 to 121.20 ± 15.87 μM for collagenase and 11.06 ± 1.87 to 27.31 ± 4.673 μM for elastase. Also, these compounds had In vitro anti-lung cancer activities. Comparison of the chemical and biological activities of the studied molecules was made by theoretical calculations. Gaussian sofware program was used for chemical activity. The Maestro molecular docking calculations were made to compare their biochemical activities. Afterwards, ADME/T calculations of the molecules were made.
