G Protein-coupled Receptors01:15

G Protein-coupled Receptors

16.4K
G Protein-Coupled Receptors or GPCRs are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to sensory stimuli such as light, odors, hormones, cytokines, or neurotransmitters.
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...

Targets for Drug Action: Overview

10.0K
Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

Drug Discovery: Overview

10.9K
Drug discovery is a multifaceted process involving extensive screening, testing, and optimization of lead compounds to identify potential new drugs for therapeutic use. It combines several approaches, including screening large numbers of natural products, chemical modification of known active molecules, identification of new drug targets, and rational design based on biological mechanisms and drug-receptor structure. These approaches are carried out in both academic research laboratories and...

Genome-wide Association Studies-GWAS

15.2K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Protein-Drug Binding: Mechanism and Kinetics

1.6K
Protein-drug binding refers to the interaction between drugs and proteins within the body. This binding process can occur intracellularly, involving drug interactions with enzymes or receptors within cells, or extracellularly, involving plasma proteins in the blood.
Various forces drive these interactions, including hydrogen bonds, hydrophobic interactions, ionic bonds, electrostatic interactions, and van der Waals forces. These bonds enable drugs to bind to specific sites on proteins,...

  • Bioinformatics and Computational Biology
  • Pharmacology and Drug Discovery
  • Genetics and Molecular Biology

Background:

  • Gout is a metabolic disorder characterized by hyperuricemia and urate crystal deposition.
  • Identifying effective therapeutic targets and novel drug candidates for gout remains a significant challenge.

Purpose of the Study:

  • To predict potential therapeutic targets for gout using an integrated bioinformatics approach.
  • To identify natural compounds with potential urate-lowering activity through molecular docking and simulation.

Main Methods:

  • Network-based analysis of gout-associated proteins using STRING and Cytoscape.
  • Prioritization of key targets SLC22A12 (URAT1) and SLC22A9 (OAT7) based on protein-protein interaction networks.
  • Molecular docking and dynamics simulations of phytochemicals against URAT1 using IMPPAT and FDA databases.

Main Results:

  • SLC22A12 (URAT1) and SLC22A9 (OAT7) were identified as key targets for gout therapy.
  • Heterophylliin A, Arctignan D, and Scutellarein 7-rutinoside exhibited strong binding affinities and stability with URAT1.
  • These natural compounds demonstrated superior binding profiles compared to existing gout medications.

Conclusions:

  • The study proposes a robust computational framework for discovering novel gout therapeutics.
  • Phytochemicals from Woodfordia fruticosa, Arctium lappa, and Oroxylum indicum are potential modulators of uric acid transport.
  • Further in vitro and in vivo validation is recommended for these promising natural compounds as gout treatments.
