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]

PI-103, as a potent class I PI3K inhibitor

3304 views | Oct 21 2012

CHARACTERIZATION of PI-103 So far, there are a lot of PI3K isozyme-selective allosteric inhibitors that have been reported. 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.

CHARACTERIZATION OF GDC-0941 PI3 kinases are identified as the lipid kinases, which involve in the regulation of breast tumor cell growth, migration, and survival. So far, there are a lot of PI3K isozyme-selective inhibitors that have been reported as the potential therapy drugs against tumors or other diseases, and GDC-0941 is one member of them. GDC-0941 is an orally bioavailable class I selective PI3K inhibitor, and produces the antitumor activity in human cancer cell lines in vitro and in vivo cancer models. GDC-0941 is a thieno[3,2-d]pyrimidine derivatives, and interacts with residues outside the active site of p110. [1] GDC-0941 has the solubility around 103 mg/mL in dimethyl sulfoxide (DMSO) , however it is scarcely soluble in both water and ethanol with solubility of less than 1 mg/mL.

PI-103, a multi-kinase inhibitor

6197 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. In preclinical studies, PI-103 potently inhibits proliferation and invasion of human cancer cells, and shows antiangiogenic potential. Moreover, PI-103 also enhances the induction of mitochondrial apoptosis by enhances downstream p53 signaling . [Read the Full Post]

MK-2206, a potent Akt inhibitor

5835 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.
