ABSTRACT

The recent emergence of a novel coronavirus strain (SARS-CoV-2) has stimulated global efforts to identify potential drugs that target proteins expressed by this novel coronavirus. Among these, the main protease of SARS-CoV-2 (3CL-protease (3CLPro), also known as (MPro) is one of the best choices for the scientists to target. 3CLPro is involved in the processing of polyproteins into mature non-structural viral proteins. An X-ray crystallographic structure (PDB ID 6LU7) of this protein was obtained from the PDB database. ChemDiv libraries of ~80,000 antiviral and ~13,000 coronavirus-targeting molecules were screened against the 3D structure of 3CLPro of SARS-CoV-2. We have identified a panel of molecules that showed an activity and potentially block the active site of the SARS-CoV-2 main protease. These molecules can be investigated further to develop effective virus-inhibiting molecules to treat this highly distressing disease, causing extreme unrest across the globe.

ABSTRAK

Kemunculan strain koronavirus baru-baru ini (SARS-CoV-2) telah mendorong usaha global untuk mengenal pasti ubat berpotensi yang mensasarkan protein yang diekspres oleh novel koronavirus ini. Antaranya, protease utama SARS-CoV-2 (3CL-protease (3CLPro), juga dikenali sebagai (MPro) adalah salah satu pilihan terbaik untuk disasarkan oleh para saintis. 3CLPro terlibat dalam pemprosesan poliprotein kepada virus protein matang tak-berstruktur. Struktur kristalografi sinar-X (PDB ID 6LU7) protein ini diperoleh dari pangkalan data PDB. Perpustakaan ChemDiv dengan ~80,000 antivirus dan ~13,000 molekul penyasaran koronavirus disaring terhadap struktur 3D 3CLPro SARS-CoV -2. Kami telah mengenal pasti panel molekul yang menunjukkan aktiviti dan berpotensi menyekat tapak aktif protease utama SARS-CoV-2. Molekul ini boleh dikaji lebih lanjut untuk mengembangkan molekul perencatan-virus yang berkesan untuk merawat penyakit yang menyebabkan keresahan melampau di seluruh dunia ini.
