Bypassing a kinase activity with an ATP-competitive drug.

The Effect of Cigarette Smoking on Human Sperm Creatine Kinase Activity: As An ATP Buffering System in Sperm

Investigation the Mechanism of Interaction between Inhibitor ALISERTIB with Protein Kinase A and B Using Modeling, Docking and Molecular Dynamics Simulation

The high level of conservation in ATP-binding sites of protein kinases increasingly demandsthe quest to find selective inhibitors with little cross reactivity. Kinase kinases are a recently discovered group of Kinases found to be involved in several mitotic events. These proteins represent attractive targets for cancer therapy with several small molecule inhibitors undergoing different ph...

A dynamically coupled allosteric network underlies binding cooperativity in Src kinase

Protein tyrosine kinases are attractive drug targets because many human diseases are associated with the deregulation of kinase activity. However, how the catalytic kinase domain integrates different signals and switches from an active to an inactive conformation remains incompletely understood. Here we identify an allosteric network of dynamically coupled amino acids in Src kinase that connect...

In Vitro Inhibition of Human Sperm Creatine Kinase by Nicotine, Cotinine and Cadmium, as a Mechanism in Smoker Men Infertility

Background Nicotine, cotinine and cadmium are harmful components of cigarettes that have an effect on human reproductive function. Although the effects of cigarette smoke on male reproductive function is characterized in several articles its mechanism of action is still unknown. In the present study, we investigate the effect of nicotine, cotinine and cadmium on human sperm creatine kinase acti...

Activity of D-carnitine and its derivatives on Trypanosoma infections in rats and mice.

Little progress has been made in the treatment of African trypanosomiasis over the past decades. L-carnitine has a major role in glycolysis-based energy supply of blood trypanosomes for it stimulates constant ATP production. To investigate whether administration of the isomer D-carnitine could exert a competitive inhibition on the metabolic pathway of the L-form, possibly resulting in parasite ...
