Chemical composition, COVİD-19 spike ACE2 binding inhibitionpotential and in silico molecular docking and admeproperties of gundelia cappadocica

COVID-19 has caused a worldwide pandemic and many people have lost their lives due to this disease. Due to the lack of a specific drug used in the treatment of this disease, interest in drug research in this direction has increased rapidly. The present study was planned to investigate the anti-COVID-19 capacity of the ethanol extract of Gundelia cappadocica Fırat. For this purpose, the anti-COVID-19 effect was studied using commercial kits. In addition, plant content was determined by HPLC-DAD. ADME properties of the identified components were studied with SwissADME web tool, while molecular docking analysis was performed using CB-DOCK2 web tool. COVID-19 inhibition was found to be 9.61% at the highest concentration of 10 µl. Resveratrol, quercetin and chrysin fulfilled all drug-like molecule criteria. In molecular docking simulations, naringin molecule showed the highest binding affinity (∆G=-9.5 kcal/mol). These results suggest that Gundelia cappadocica can be used in the prevention and treatment of COVID19.
