Study Notes

Modern combinatorial approach to drug discovery may not completely replace the need for new drug leads from natural sources due to unmet clinical needs such as anti-virals, antibiotics, and anti-cancers.
Combinatorial chemistry relies on compound libraries, which only sample a part of the chemical diversity present in nature.
Pharmaceutical companies are sharing their compound libraries to increase drug discovery efficiency.
New chemical entities (NCE) as drugs are still necessary for drug discovery.
Medicinal chemists play a crucial role in the drug discovery process by utilizing their skills to design drugs based on the 3D nature of the molecule and the receptor.
Natural drug leads offer a higher diversity of chemical compounds and more rigid compounds, which are more specific.
Combinatorial approaches introduce more non-rigid bonds, lowering the specificity and making leads less effective.
Drug discovery is a lengthy process with a low rate of new therapeutic discoveries.
New targets as opposed to established targets are more prone to drug discovery project failure.
The pharmaceutical industry is trending towards more risk-averse target selection.
Combinatorial approaches have provided effective ways to discover drug leads.
An abundance of natural organisms have not been screened for potentially new leads.
Ethnopharmacology and bioprospecting can be used to identify new drug leads from natural sources.
Structure-based design and molecular modelling can be employed to design drugs based on the binding site and ligand interactions.
Molecular modelling can be used to study different compounds which react with target proteins.
Comparison of compounds can identify a suitable lead compound.
De Novo drug design is a novel approach to designing drugs based on the structure of the target.
Crystallography and molecular modelling can be used to identify the binding site and optimize the lead compound.
Molecular modelling can help identify potential binding regions in the binding site.
Molecular modelling can be used to study membrane-bound proteins.
Alternative approaches such as identifying similar proteins with known crystal structures and designing drugs for the target protein can be employed.
Molecular modelling can help identify synergistic effects and modifications that improve drug activity.
A controlled approach to targeting multiple diseases using a cocktail of drugs can reduce the number of treatments required.
