⚫ | '''Wortmannin''', a steroid metabolite of the fungi ''[[Penicillium funiculosum]]'', ''[[Talaromyces wortmannii]]'', is a non-specific, [[covalent]] inhibitor of [[phosphoinositide 3-kinase]]s (PI3Ks). It has an ''in vitro'' [[IC50|inhibitory concentration]] (''IC''<sub>50</sub>) of around 5 nM, making it a more potent inhibitor than [[LY294002]], another commonly used [[PI3K inhibitor]]. It displays a similar potency ''in vitro'' for the [[class I PI 3-kinases|class I]], [[class II PI 3-kinases|II]], and [[Class III PI 3-kinase|III]] PI3K members although it can also inhibit other PI3K-related enzymes such as [[mTOR]], [[DNA-PKcs]], some [[phosphatidylinositol 4-kinase]]s, [[myosin light chain kinase]] (MLCK) and [[mitogen-activated protein kinase]] (MAPK) at high concentrations<ref name="pmid11395417">{{cite journal | vauthors = Vanhaesebroeck B, Leevers SJ, Ahmadi K, Timms J, Katso R, Driscoll PC, Woscholski R, Parker PJ, Waterfield MD | title = Synthesis and function of 3-phosphorylated inositol lipids | journal = Annual Review of Biochemistry | volume = 70 | pages = 535–602 | date = 2001 | pmid = 11395417 | doi = 10.1146/annurev.biochem.70.1.535 }}</ref><ref name="pmid9131167">{{cite book | vauthors = Ferby I, Waga I, Kume K, Sakanaka C, Shimizu T | title = Platelet-Activating Factor and Related Lipid Mediators 2 | chapter = PAF-Induced MAPK Activation is Inhibited by Wortmannin in Neutrophils and Macrophages | series = Advances in Experimental Medicine and Biology | volume = 416 | pages = 321–6 | date = 1996 | pmid = 9131167 | doi = 10.1007/978-1-4899-0179-8_51 | isbn = 978-1-4899-0181-1 }}</ref> Wortmannin has also been reported to inhibit members of the [[polo-like kinase]] family with ''IC''<sub>50</sub> in the same range as for PI3K.<ref name="pmid17135248">{{cite journal | vauthors = Liu Y, Jiang N, Wu J, Dai W, Rosenblum JS | title = Polo-like kinases inhibited by wortmannin.

==Phosphoinositide-3-kinase== |
||
⚫ | [[Phosphoinositide-3-kinase]] (PI3K) activates an important cell survival signaling pathway, and constitutive activation is seen in ovarian, head and neck, urinary tract, cervical and small cell lung cancer. PI3K signaling is attenuated by the phosphatase activity of the tumor suppressor PTEN that is absent in a number of human cancers. Inhibiting PI3K presents the opportunity to inhibit a major cancer cell survival signaling pathway and to overcome the action of an important deleted tumor suppressor, providing antitumor activity and increased tumor sensitivity to a wide variety of drugs. |
