RESEARCH: COVID-19
FOLDING PROJECT #18488 PROFILE

The project relates to using computer simulations to see how small molecules bind to a protein from the SARS-CoV-2 virus. This will help scientists design new drugs to fight COVID-19. The results will be compared to real lab experiments done as part of the COVID Moonshot initiative.

Note: This TLDR is a simplication and may not be 100% accurate.

In fragment-based drug discovery, high-throughput screening is used to identify a set of simple, low-affinity (milli-to-micromolar) molecular fragments that bind a protein target.

Information about the chemical and structural properties of the fragments are then used to inform the design of more potent binders.

Are molecular simulations of fragment binding up to the task of providing similarly accurate information? The recent availability of crystallographic fragment screening datasets, along with high-resolution structures of fragment-bound protein receptors, offers a unique opportunity to test this hypothesis.
In this project, we are simulating the binding of several small-molecule fragments to the SARS CoV-2 main protease dimer, the results of which we will compare to crystallographic fragment-screening data generated as part of the COVID Moonshot.

fragment-based drug discovery

A method of drug design that involves identifying small molecules that bind to a target protein and then optimizing these fragments for potency.

Fragment-based drug discovery is a powerful technique used to develop new drugs. It starts by finding small molecules that weakly bind to a specific target protein. These fragments are then modified and improved until they become potent inhibitors of the target, leading to the development of new therapeutic agents.

high-throughput screening

A method for rapidly testing thousands of compounds against a biological target to identify potential drug candidates.

High-throughput screening (HTS) is a crucial technique in drug discovery. It involves testing a vast number of chemical compounds against a specific biological target, such as a protein or enzyme. This allows researchers to quickly identify promising drug candidates that interact with the target and have the desired effect.

molecular fragments

Small molecules that bind to a target protein but may not be potent inhibitors on their own.

Molecular fragments are small chemical building blocks that have the potential to interact with biological targets. In drug discovery, they serve as starting points for developing more potent and specific drugs. By identifying fragments that bind to a target protein, researchers can then modify and optimize these fragments to create more effective therapeutic agents.

protein target

A specific protein that is the intended target of a drug.

Protein targets are essential components in drug discovery. They are specific proteins involved in biological processes that can be modulated by drugs to achieve therapeutic effects. Identifying and understanding the structure and function of protein targets allows researchers to develop drugs that specifically interact with these targets, leading to the desired therapeutic outcome.

crystallographic fragment screening

A method for identifying fragments that bind to a protein target using X-ray crystallography.

Crystallographic fragment screening is a powerful technique used in drug discovery. It involves determining the three-dimensional structure of a protein bound to small molecule fragments. By analyzing these structures, researchers can identify fragments that interact with specific sites on the protein, providing valuable information for developing new drugs.

SARS CoV-2

Severe Acute Respiratory Syndrome Coronavirus 2

SARS-CoV-2 is the virus responsible for the disease COVID-19. It is a highly contagious respiratory virus that can cause severe illness and death. Researchers are actively working to develop vaccines and treatments for SARS-CoV-2.

main protease dimer

A key enzyme in the SARS-CoV-2 virus that is essential for viral replication.

The main protease dimer is a crucial enzyme found in the SARS-CoV-2 virus. It plays a vital role in viral replication by cleaving viral proteins into smaller functional units. Inhibiting this enzyme is a promising strategy for developing antiviral drugs against COVID-19.

COVID Moonshot

A global initiative to accelerate the development and deployment of vaccines, treatments, and diagnostics for COVID-19.

The COVID Moonshot is a large-scale collaborative effort aimed at rapidly developing and distributing solutions to combat the COVID-19 pandemic. It involves researchers, scientists, governments, and organizations from around the world working together to accelerate the development of vaccines, treatments, and diagnostic tools.
