Abstract

Insights

Monoclonal antibodies targeting proprotein convertase subtilisin kexin type 9 (PCSK9) inhibitors significantly lower LDL cholesterol. Recent clinical trials show PCSK9 inhibition is safe and effective for patients reaching cholesterol goals.

Area of Science:

  • Cardiovascular Medicine
  • Pharmacology
  • Genetics

Background:

  • Proprotein convertase subtilisin kexin type 9 (PCSK9) is a validated target for lowering LDL cholesterol.
  • PCSK9 acts as a secreted inhibitor of the LDL receptor.
  • Genetic regulation of PCSK9 by statins has been observed.

Purpose of the Study:

  • Review recent reports on PCSK9 inhibitors.
  • Summarize discovery and mode of action of PCSK9.
  • Focus on Phase I and II clinical trials of PCSK9 inhibitors.

Main Methods:

  • Literature review of 500 publications up to March 2013.
  • Analysis of Phase I and II clinical trial data from 2012.
  • Review of in-vivo studies on long-term PCSK9 inhibition.

Main Results:

  • Phase I and II trials in 2012 demonstrated significant LDL-C reduction with PCSK9 inhibitors.
  • Patients achieved target LDL-C goals with these therapies.
  • No severe or serious safety issues were reported in trials.

Conclusions:

  • PCSK9 inhibitors show promise in managing hypercholesterolemia.
  • Potential cardiovascular benefits of long-term PCSK9 inhibition warrant further investigation.
  • Potential side-effects of PCSK9 inhibition require discussion.

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...

Antiplatelet Drugs: Prostaglandin Synthesis, P2Y12 and Glycoprotein IIb/IIIa Inhibitors

Antiplatelet drugs emerge as frontline defenders against the insidious threat of thromboembolic diseases, where abnormal clots obstruct vital blood vessels. These drugs stand as bulwarks, inhibiting platelet aggregation and clot formation, thereby mitigating the risk of life-threatening conditions like myocardial infarction, coronary artery disease, and thrombotic strokes.
Prostaglandin synthesis inhibitors, exemplified by the widely known aspirin, wield their power by irreversibly acetylating...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:
Dipeptidyl Peptidase 4 Inhibitors01:23

Dipeptidyl Peptidase 4 Inhibitors

Dipeptidyl peptidase 4 (DPP-4) is a serine protease widely distributed in the body. It's involved in the inactivation of GLP-1 and GIP hormones, which are crucial for insulin regulation. DPP-4 inhibitors, such as sitagliptin (Januvia), saxagliptin (Onglyza), linagliptin (Tradjenta), alogliptin (Nesina), and vildagliptin (Galvus), help increase the proportion of active GLP-1, enhancing insulin secretion. These inhibitors work by competitively binding to DPP-4. This binding causes a significant...
Inhibition of CDK Activity02:34

Inhibition of CDK Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...
