Drug action

Amlodipine is a representative active ingredient of calcium channel blockers. In addition to the general advantages of calcium channel blockers in treating hypertension, amlodipine also effectively controls blood pressure for 24 hours and has no or just a little effect on neurohormonal activation, so it does not cause high blood pressure at the last dose. However, amlodipine has a plasma half-life of between 30 and 40 hours, slowing the drug's action duration.

Regulator of G-protein signaling (RGS) proteins were originally identified as negative regulators of G-protein-coupled receptor (GPCR) signaling via their GTPase-accelerating protein (GAP) activity. All RGS proteins contain evolutionarily conserved RGS domain; however, they differ in their size and regulatory domains. RGS1 and RGS10 are smaller than other RGS proteins, and their functions involve various inflammatory responses including autoimmune responses in both the periphery and the central nervous system (CNS). Neuroinflammation is the chronic inflammatory response in the CNS.

Serotonin transporters are key target sites for clinical drugs and psychostimulants, such as fluoxetine and cocaine. Molecular cloning of a serotonin transporter from the cen-tral nervous system of the insectManduca sextaenabled us to define domains that affect antagonist action, particularly cocaine.

Liver microsomal preparations are routinely used to predict drug interactions that can occurin vivo as a result of inhi-bition of cytochrome P450 (CYP)-mediated metabolism. However, the concentration of free drug (substrate and inhibitor)at its intrahepatic site of action, a variable that cannot be directly measured, may be significantly different from that in microsomal incubation systems.

The transient receptor potential channel vanilloid receptor subunit 1 (TRPV1) is amolecular integrator of physical and chemical stimuli in the peripheral nociceptor terminals. TRPV1 is an ionotropic channel that plays a critical role in both thermal nociception and inflammatoryhyperalgesia. Structure–function relationships are providing fundamental insights of the modular architecture of this neuronal recep-tor.

Prolonged exposure of pancreatic beta cells to the sulfonylureas glibenca-mide and tolbutamide induces subsequent desensitization to the actions of these drugs. The precise mechanisms underlying this desensitization remain unknown, prompting the present study, which investigated the impact of prolonged sulfonylurea exposure on glucose and energy metabolism using clonal pancreatic BRIN-BD11 beta cells.

L-3,4-Dihydroxyphenylalanine (L-dopa) remains the most effective phar-macological treatment for relief of the severe motor impairments of Par-kinson’s disease. It is very effective in controlling parkinsonian symptoms in the initial phase of the disease, but its action wanes with time. Such ‘wearing-off’ imposes an escalation in the dosage of the drug, which ulti-mately fails to provide stable control of motor symptoms and results in the appearance of abnormal involuntary movements or dyskinesia....

Small molecules that activate the transcriptional function of wild type p53 have proved active as anti-cancer drugs in preclinical models and are now entering clinical trial. The complexity of the upstream p53 signaling pathway offers many targets for the devel-opment of such activators and the action of Mdm2 inhibitors, kinase inhibitors, sirtuin inhibitors and low doses of actinomycin D will be described among other examples.

Many drugs have unknown, controversial or multiple mechanisms of action. Four recent ‘chemical genomic’ studies, using genome-scale collections of yeast gene deletions that were either arrayed or barcoded, have presented complementary approaches to identifying gene-drug and pathwaydrug interactions. deposited research The fact that much of modern drug research is target-oriented obscures the long history during which the effects of drugs were discovered prior to identification of their targets. There remain many...
