What is XL765?

The Uses of XL765

XL765 is a low-molecular mass PI3K inhibitor that also inhibits DNA-PK and mTOR.

What are the applications of Application

XL-147 derivative 1 is a potent class I PI3K inhibitor

Definition

ChEBI: XL765 is a sulfonamide obtained by formal condensation of the sulfonic acid group of 4-[(3-methoxy-4-methylbenzoyl)amino]benzenesulfonic acid with the primary aromatic amino group of N-(3,5-dimethoxyphenyl)quinoxaline-2,3-diamine. A dual PI3K/mTOR inhibitor used in cancer treatment. It has a role as an EC 2.7.1.137 (phosphatidylinositol 3-kinase) inhibitor, an antineoplastic agent and a mTOR inhibitor. It is a sulfonamide, a quinoxaline derivative, an aromatic amine, a member of benzamides and an aromatic ether.

Biological Activity

sar245409 (xl765) is a selective dual inhibitor of pi3k and mtor (ic50= 9 nm for pi3kγ).pi3k (phosphatidylinositol-4,5-bisphosphate 3-kinase) is a family of enzymes involved in cellular functions such as cell growth, proliferation, differentiation, motility, survival and intracellular trafficking, which in turn are involved in cancer. it plays a key role in pi3k/akt/mtor pathway.in pa cell lines, combination of xl765 and tmz blocked the cell growth and led to apoptosis [1]. in a variety of tumor cell lines that mutated on pi3k signaling, xl765 inhibited pip3 formation in the membrane and akt/p70s6k/s6 phosphorylation [2].in gh3 xenograft tumor mouse models, combination use of xl765 and tmz inhibited tumor growth, reduced serum gh and prolactin levels with no increased systemic side effects [1]. in severe combined immunodeficient mice, xl765 abolished mpnst local and metastatic growth. [3]. in multiple human xenograft models in nude mice, repeat dose administration showed significant tumor growth inhibition that related to antiproliferative and antiangiogenic response etc. [2]
