HIGH THROUGHPUT SCREENING HELPING THE DRUG DISCOVERY

3874 views | Oct 14 2012

HIGH THROUGHPUT SCREENING: INTRODUCTION: In pharmaceutical industries different techniques are important and used for the novel drug discovery. Among these techniques the most effective one in this area is high throughput chemical screening. It is also named as HTS assays or high throughput assays which are being used for the biological, pharmacological assessment or the assessment of biochemical activities of a large number of drugs by the help of the latest automatic technology. Such technology is not only helpful in discovery of appropriate receptors, enzymes, ligands for different ion channels and the other pharmacologically important targets but also used in the extensive studies of various desired biochemical or cellular pathways by the aid of unknown and novel chemical agents. Regarding this an important example is of the screening of kinase inhibitor library for screening that is much easier than various other traditional methodologies. Reviews of high throughput screening are an efficient source of acknowledging the importance of HTS. These reviews reveal the speed and accuracy of high throughput screening in the pharmaceutical industries in improving the scientific approaches and business structures. [Read the Full Post]

GDC-0941, A NOVEL PI3K INHIBITOR

9981 views | Oct 12 2012

GDC-0941 As is known, there have been several identified PI3 kinases, which are divided into classes IA, 1B, II, and III according to the differences of sequence homology and substrate preference. Besides, the PI3K superfamily also includes the Class IV PIK related enzyme family of protein kinases including mTOR, ATM, ATR, and DNA-PK. Of which, Class IA PI3K is a heterodimer composed of a p110 catalytic subunit and a p85 regulatory subunit, and there are three variants of the p110 catalytic subunit designated p110α, β, or δ catalytic subunit. PI3 Kinase is an oncogene that is commonly mutated in cancer. Hence inhibition of PI3K, and in particular p110α, is a promising target for cancer treatment. [Read the Full Post]

KINASE INHIBITORS IN CANCER THERAPY

3573 views | Oct 10 2012

KINASES IN CELL SIGNALLING: Kinases can rightly be called as the gateways of the cells due to their role in signal transduction in the cell. They function by activating or stimulating the critical pathway by phosphorylating the protein molecules. After getting stimulated enzymes allow the cells to perform some specific functions necessary for its proliferation, survival and growth etc. kinases are of many types which are Receptor tyrosine kinases (RTKs), non-receptor tyrosine kinases (NRTKs) and serine/threonine kinases. Mixed kinases and histidine kinases are also some of the examples of kinases. Basically kinases themselves get activated by a signaling molecule like a ligand from the extracellular environment or some other kinases and further activate subsequent molecule by phosphorylating or dephosphorylating them. Aurora kinase is an important example of kinase enzymes. Different types of agonist and antagonist molecules are used to study and unveil different functions of kinases in the cells. Kinase inhibitor is one of the examples of outcomes of such research on kinases and their inhibition. Different types of kinase assays are also there to study and analyze some specific kinds of kinases. [Read the Full Post]
