The importance of HER2 in cancer was realized in the early 1980s when a mutationaly activated form of its rodent homologue neu was identified in a search for oncogenes in a carcinogen induced rat tumorigenesis Topotecan model (Shih et al. 1981). Its human homologue HER2 was simultaneously cloned and found to be amplified in a GS-1101 breast cancer cell line (King et al. 1985). [Read the Full Post]

For example, PIK-75 is a p110alpha-specific inhibitor, TGX-221 is a p110beta-specific inhibitor and IC87114 is a p110delta-specific inhibitor. These PI3K inhibitors are promising agents in the treatment of cancer and other diseases, and PI-103 is one of them. PI-103 is a potent, cell-permeable, ATP-competitive class I PI3K inhibitor. The structure analysis indicates that PI-103 is a pyridinylfuranopyrimidine molecule and ATP-competitive PI3K inhibitor. PI-103 has the solubility around 24 mg/mL in both dimethyl sulfoxide (DMSO), however it is scarcely soluble in ethanol and water with solubility of less than 1 mg/mL. And the approximate price of PI-103 is $151 per 10 mg and $466 per 50 mg in selleckchem.com, and PI-103 price may vary according to the proportion purity of the preparation and/or from one PI-103 supplier to different ones.

PI-103, a multi-kinase inhibitor

6261 views | Oct 17 2012

PI-103 According to the critical roles of PI3K for cell growth and survival, a series of isoform-selective inhibitors of the PI3 kinase family, such as PI-103, PIK-90, and TGX-468 are synthesized and identified to block phosphorylation of Akt, the downstream effector of PI3 kinase in cancer cell lines. PI103 is a promising tricyclic pyridofuropyrimidine lead and chemical tool compound, and a potent inhibitor with low IC50 values against recombinant PI3K isoforms including p110alpha, p110beta, p110delta,, and p110gamma. Besides, PI-103 also produces effective inhibitory activity against mTORC1 and DNA-PK in the low concentration.

5915 views | Oct 16 2012

Characterization of MK-2206 Akt is identified as a serine-threonine kinase on the basis of its homology to protein kinase A (PKA), protein kinase C (PKC) and the retroviral oncogene, viral Akt. The known three human AKT isozymes (Akt1, Akt2 and Akt3) are highly homologous multi-domain proteins with both overlapping and distinct cellular functions. So far, there are a lot of AKT isozyme-selective allosteric inhibitors that have been reported, and MK-2206 is one member of them. MK-2206 is a potent, oral allosteric inhibitor of all AKT isoforms, which binds to a site outside the PH domain and binds very weakly to the PH domain of Akt. MK-2206 has the solubility around 96 mg/mL in both dimethyl sulfoxide (DMSO) and water, however it is scarcely soluble in ethanol with solubility of 2 mg/mL. And the approximate price of MK-2206 is $214 per 10 mg and $718 per 50 mg in selleckchem.com, and MK-2206 price may vary according to the proportion purity of the preparation and/or from one MK-2206 supplier to different ones.

FEATURES OF PERIFOSINE Perifosine, also known as KRX-0401, is a synthetic novel alkylphospholipid (ALP) and a potent antitumor agents which inhibits PH domain mediated AKT membrane recruitment and activation. Perifosine structure has been elucidated through X-ray crystallography and it shows the similar structure with phospholipids that are the main constituents of cellular membranes. Perifosine is soluble in water and ethanol with solubility of 14 mg/mL and 92 mg/mL, respectively. But Perifosine solubility in DMSO is poor. Commercially researchers can obtain Perifosine with the price of about $210/mg from suppliers selleck chemicals. Perifosine stability keeps good for at least 2 years for the dry solid when stored at -20°C and for 6 months at -80°C in DMSO. [Read the Full Post]

HIGH THROUGHPUT SCREENING HELPING THE DRUG DISCOVERY

3455 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

9477 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]
