Insights

Selective cyclo-oxygenase 2 (COX2) inhibitors, known as coxibs, demonstrate significant anticancer effects by inhibiting tumor growth and potentiating other treatments. Clinical studies show promising results for coxibs combined with chemotherapy in various cancers.

Area of Science:

  • Oncology
  • Pharmacology

Background:

  • Cyclo-oxygenase 2 (COX2) plays a crucial role in tumor development and progression.
  • Selective COX2 inhibitors (coxibs) exhibit antiangiogenic and proapoptotic effects, inhibiting tumor growth.
  • COX2 is overexpressed in advanced human tumors, indicating its therapeutic relevance.

Purpose of the Study:

  • To review recent findings on the anticancer effects of coxibs.
  • To explore therapeutic opportunities for combining coxibs with other anticancer modalities.

Main Methods:

  • Review of experimental studies on coxibs' antitumour mechanisms.
  • Analysis of preclinical models demonstrating coxib efficacy.
  • Evaluation of clinical trial data on coxib combinations.

Main Results:

  • Coxibs inhibit tumor growth via antiangiogenic and proapoptotic mechanisms.
  • Coxibs enhance the efficacy of chemotherapy, hormonal therapy, and radiotherapy in experimental models.
  • Clinical studies show coxibs are feasible, well-tolerated, and effective when combined with chemotherapy for colorectal and non-small-cell lung cancers.

Conclusions:

  • Preclinical and clinical findings support the use of coxibs in anticancer strategies.
  • Combination therapy with coxibs offers promising opportunities for cancer treatment, particularly in advanced stages.

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...

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.

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...

Inhibitors of Bacterial DNA Synthesis

Bacterial pathogens depend on precise and efficient DNA replication to sustain infection. Two type II topoisomerases—DNA gyrase and topoisomerase IV—are critical to this process, as they resolve DNA supercoiling and unlink chromosomes during replication. Fluoroquinolones, synthetic derivatives of quinolones, exploit this mechanism by stabilizing the transient DNA–enzyme cleavage complex, preventing strand religation, and causing lethal double-strand breaks. These antibiotics are selectively...
