General description

A cell-permeable pyridinylfuranopyrimidine compound that acts as a potent and ATP-competitive inhibitor of DNA-PK, PI3-K, and mTOR (IC50 = 2, 8, 88, 48, 150, 26, 20, and 83 nM for DNA-PK, p110α, p110β, p110δ, p110γ, PI3-KC2β, mTORC1, and mTORC2, respectively). It inhibits ATR and ATM only at much higher concentrations (IC50 = 850 and 920 nM, respectively) and exhibits little activity towards a panel of more than 40 other kinases even at concentrations as high as 10 µM. Shown to effectively block PI3-K/Akt signaling and cell proliferation in glioma cell lines both in vitro and in vivo. A 10 mM (2 mg/574 µl) solution of PI-103 (Cat. No. 528101) in DMSO is also available.

Extensive evidence implicates activation of the lipid phosphatidylinositide 3-kinase (PI3K) pathway in the genesis and progression of various human cancers. PI3K inhibitors thus have considerable potential as molecular cancer therapeutics. Here, we detail the pharmacologic properties of a prototype of

The PI3 kinase family of lipid kinases promotes cell growth and survival by generating the second messenger phosphatidylinositol-3,4,5-trisphosphate. To define targets critical for cancers driven by activation of PI3 kinase, we screened a panel of potent and structurally diverse drug-like

Phosphoinositide 3-kinases (PI3-Ks) are an important emerging class of drug targets, but the unique roles of PI3-K isoforms remain poorly defined. We describe here an approach to pharmacologically interrogate the PI3-K family. A chemically diverse panel of PI3-K inhibitors was

SQSTM1/p62, as a major autophagy receptor, forms droplets that are critical for cargo recognition, nucleation, and clearance. p62 droplets also function as liquid assembly platforms to allow the formation of autophagosomes at their surfaces. It is unknown how p62-droplet formation

Cancer Stem Cell Detection Utilizing a Red-shifted Fluorescent Live Cell Probe for Aldehyde Dehydrogenase (ALDH), AldeRed™ 588-A.

AldeRed™ 588-A is a red fluorescent live cell probe that detects ALDH activity used to identify cancer stem cells and progenitor cells in culture. Cancer stem cells (CSCs) are subpopulations of cancer cells that can self-renew, generate diverse cells in the tumor mass, and sustain tumorigenesis. Some researchers believe that cancer arises from cancer stem cells that originate as a result of mutational hits on normal stem cells.
