COVID-19 is the infectious pandemic disease caused by the novel coronavirus. The COVID-19 is spread globally in a short span of time. The Ministry of AYUSH, India which promotes Siddha and other Indian system of medicine recommends the use of formulation like Nilavembu Kudineer and Kaba Sura Kudineer Chooranam (KSKC). The present work seeks to provide the evidence for the action of 74 different constituents of the KSKC formulation acting on two critical targets. That is main protease and SARS-CoV-2 RNAdependent RNA polymerase target through molecular docking studies. The molecular docking was done by using AutoDock Tools 1.5.6 of the 74 compounds, about 50 compounds yielded docking results against COVID-19 main protease while 42 compounds yielded against SARSCoV- 2 RNA-dependent RNA polymerase. This research has concluded that the KSKC has the lead molecules that inhibits COVID-19’s target of main protease of COVID-19 and SARS-CoV-2 RNA-dependent RNA polymerase.

The novel coronavirus known as SARS-CoV-2 and the virus-induced disease COVID-19 has caused widespread concerns due to its contagiousness, fatality rate, and the absence of drug(s). This study investigated Lens culinaris and its phytochemicals, especially the flavonoids. The compounds were assessed through molecular docking studies for their binding abilities with the major protease of the novel coronavirus, SARS-CoV-2 (PDB: 6LU7). A total of 42 phytochemicals of Lens culinaris were analyzed through molecular docking studies for their binding affinities to COVID 3C-like protease. Of them, 23 compounds were found to have binding affinities to the protease of −7.5 kcal/mol or higher. Our study indicates that Lens culinaris contains a number of polyphenolic compounds as well as phytosterols, which can bind to the active site of the protease, and so merits further scientific attention on trials for use as potential anti-COVID-19 drugs.

Herein, the novel pyrazole derivatives with imino moiety were synthsized, characterized using IR, NMR, mass spectroscopy, elemental analysis and screened their biological activities. Molecular docking studies were also carried out by the software Arguslab 4.0.1. The synthesized compounds showed moderate to good biological activities both experimentally and theoretically.

A 3D model of Cyclin-dependent kinase 5 (CDK5) (Accession Number: Q543f6) is generated based on crystal structure of P. falciparum PFPK5-indirubin-5-sulphonate ligand complex (PDB ID: 1V0O) at 2.30 Å resolution was used as template. Protein-ligand interaction studies were performed with flavonoids to explore structural features and binding mechanism of flavonoids as CDK5 (Cyclin-dependent kinase 5) inhibitors. The modelled structure was selected on the basis of least modeler objective function. The model was validated by PROCHECK. The predicted 3D model is reliable with 93.0% of amino acid residues in core region of the Ramachandran plot. Molecular docking studies with flavonoids viz., Diosmetin, Eriodictyol, Fortuneletin, Apigenin, Ayanin, Baicalein, Chrysoeriol and Chrysosplenol-D with modelled protein indicate that Diosmetin is the best inhibitor containing docking score of -8.23 kcal/mol. Cys83, Lys89, Asp84. The compound Diosmetin shows interactions with Cys83, Lys89, and Asp84.
