Clopidogrel Resistance: case reports of CYP2C19 gene variants in suspected coronary stent thrombosis.

Clopidogrel is a widely used anti-platelet agent for the prevention of arterial thrombosis. Clopidogrel is administered as a pro-drug and metabolised to its active metabolite by the hepatic cytochrome P450 2C19 (CYP2C19) enzyme. The active metabolite is responsible for the anti-platelet activity of clopidogrel.

A novel histone deacetylase inhibitor augments tamoxifen-mediated attenuation of breast carcinoma growth.

Earlier we generated novel derivatives of the hydroxamate-based histone deacetylase inhibitor (HDACi), Oxamflatin (Ox), which demonstrate considerable HDACi activity. Here the effects of one such derivative, Metacept-1 (MCT-1), alone or in combination with tamoxifen on mammary tumour growth have been assessed in a syngeneic orthotopic model. MCT-1 alone resulted in a trend towards inhibition of growth of 4T1.
