Abstract:

The coronavirus disease affects the whole world with the pandemic process that is still ongoing. The fight against the disease is continuing throughout the world, with vaccination studies. Considering the duration of protection and the difficulties in obtaining the vaccine, medications that allow the virus to be killed or replicated are needed to be successful in the fight against the disease. After the study of the effects of phytochemicals on the virus in drug studies, the method of modification of isolated molecules is applied to make more effective molecules synthesized. It is impossible to analyze the anti-viral activity of each isolated molecule with in-vitro methods and in-silico methods can help overcome this problem. Cistus incanus is a plant that has previously been confirmed with anti-viral activity by testing many viruses. After the content analysis in this study, the interaction of myricetin 3-O-hexoside, myricitin, quercitrin and kaempferol 3-O-rutinocide molecules found in Cistus incanus with papain-like protease and main protease was analyzed by molecular tissue methods. The results of the analyses have found strong H-bindings between the molecules studied and the papain-like protease and the main protease.

Abstract:

Coronavirus disease affects all the world with the pandemic way that we are still living. The fight against the disease continues with vaccination all over the world. Considering the protection time and the difficulties in attaining the vaccine, in order to be successful in fighting against the disease, we need drugs that enable to kill or hinder replication of the viruses. In drug studies, after analyzing the effect of phytochemicals on the viruses, isolated phytochemical is modified in order to synthesize a more effective molecule. It is not possible to analyze the anti-viral activity of each isolated molecule by in-vitro methods, and in-silico methods can help to overcome this problem. Cistus incanus is a plant whose anti-viral activity has been confirmed by previous trials on many viruses. In this study, the interaction of myricetin 3-O-hexoside, myricitrin, quercitrin and kaempferol 3-O-rutinocide which were detected in the Cistus incanus, were analyzed by molecular docking methods with papain-like protease and main protease crystal. Strong H-bonds were detected between the investigated molecules and papain-like protease and main protease.
