Uses
Different sources of media describe the Uses of 19545-26-7 differently. You can refer to the following data:
1. Wortmannin is a steroidal metabolite belonging to the viridin group, isolated from Penicillium wortmannii in 1957. The structure was finally solved in 1968. Wortmannin exhibits broad spectrum antifungal activity, together with antitumour and antiinflammatory activity. Wortmannin is a potent inhibitor of phosphoinositide 3-kinase and myosin light chain kinase. Wortmannin also activates neutrophil and formyl-Met-Leu-Phe-mediated phospholipase D, inhibits autophagy, potentiates LPS-induced NO production and induces Alzheimer-like hyperphosphorylation in tau in vivo.
2. Wortmannin is used as inhibitor of phosphatidylinositol 3-kinase, used cell biology reagent that has been used previously in research to inhibit DNA repair, receptor-mediated endocytosis and cell proliferation. It inhibits fMLP induced PIP3 and superoxide anion production in guinea pig neutrophils. It blocks insulin metabolic effects in rat adipocytes without affecting the insulin receptor tyrosine kinase activity.
3. Wortmannin, Ready Made Solution has been used: as a phosphoinositide 3-kinase (PI3K) pathway inhibitoras an endoderm-inducing agent in stem cell selection and differentiation as a autophagy inhibitor
Biological Activity
Potent, selective, cell-permeable and irreversible inhibitor of phosphatidylinositol 3-kinase (PI 3-kinase) (IC 50 = 2-4 nM). Also potently inhibits polo-like kinase 1 (PLK1) (IC 50 = 5.8 nM).
Biochem/physiol Actions
Wortmannin is a low molecular weight; hydrophobic fungal metabolite with a sterol-like structure produced by Penicilium fumiculosum. Inhibition of PI3K/Akt signal transduction cascade by wortmannin, enhances the apoptotic effects of radiation or serum withdrawal and blocks the antiapoptotic effect of cytokines. PI3K inhibition by wortmannin also blocks many of the short-term metabolic effects induced by insulin receptor activation. Research has demonstrated that wortmannin inhibits two enzymes from mitotical division, key regulators Polo-like kinase (Plk) family, Plk1 and Plk3.

Check Digit Verification of cas no
The CAS Registry Mumber 19545-26-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,5,4 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 19545-26:
(7*1)+(6*9)+(5*5)+(4*4)+(3*5)+(2*2)+(1*6)=127
127 % 10 = 7
So 19545-26-7 is a valid CAS Registry Number.

Wortmannin-C20 conjugates generate wortmannin
Yuan, Hushan,Luo, Ji,Weissleder, Ralph,Cantley, Lewis,Josephson, Lee
, p. 740 - 747 (2006)
We report on C20-6-(N-methylamino)hexanoic conjugates of wortmannin featuring a tertiary enamine attached to the C20 that inhibit phosphoinositol-3-OH kinase (PI3K) by producing wortmannin (Wm) through an intramolecular attack. The generation of Wm by these conjugates permits the design of Wm based PI3K inhibitors that need not fit into the ATP pocket of PI3K, including Wm conjugates of BSA, IgG, or beads. Wm generating WmC20-N(Me)-hexanoate conjugates offer an approach to the design of targeted or slow release forms of Wm which may inhibit PI3K in tissues more selectively than the parent Wm, a compound which has desirable anti-inflammatory and anti-proliferative activities but which also has a variety of toxic effects.
