Insights

Targeting G protein subunits (Gα and Gβγ) offers a novel therapeutic strategy for complex diseases. This review explores inhibitors for G protein alpha and beta-gamma subunits, focusing on their cancer treatment potential.

Area of Science:

  • Pharmacology
  • Molecular Biology
  • Oncology

Background:

  • G-Protein-coupled receptors (GPCRs) are crucial in physiological processes and are major drug targets.
  • GPCR signaling involves G protein alpha (Gα) and beta-gamma (Gβγ) subunits.
  • Targeting downstream effectors, including G proteins, is a promising therapeutic strategy for complex diseases.

Purpose of the Study:

  • To discuss the requirements for targeting Gα and Gβγ subunits.
  • To review the mechanisms of action of identified G protein inhibitors.
  • To focus on the potential utility of Gα and Gβγ inhibitors in cancer treatment.

Main Methods:

  • Review of existing literature on G protein subunit modulators.
  • Analysis of small molecule inhibitors targeting Gα and Gβγ subunits.
  • Evaluation of preclinical data from animal models of disease.

Main Results:

  • Several small molecule modulators of Gα and Gβγ subunits have been developed.

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...

G Protein-coupled Receptors01:15

G Protein-coupled Receptors

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

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...

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...
