RO4929097 Usage And Synthesis

Uses

Ro 4929097 acts as a γ-secretase inhibitor used in the treatment of those suffering from solid tumors. It is used to treat pancreatic adenocarcinoma.

Definition

ChEBI: A member of the class of dibenzoazepines that is the amide formed from formal condensation of the carboxy group of 2,2-dimethyl-3-oxo-3-[(2,2,3,3,3-pentafluoropropyl)amino]propanoic acid with the amino group of (7S)-7-amino-5,7-dihydrodibe zo[b,d]azepin-6-one.

Biological Activity

ro4929097 is a small-molecule inhibitor of γ secretase with ic50 of 4 nm and ec50 of 5 nm [1]. it shows no in vitro inhibitory activity on the closely related proteases. it also has greater than 100-fold selectivity with respect to 75 other proteins of various types [1]. ro4929097 binds to γ secretase and inhibits its protease activity, therefore blocking the cleavage of notch and reducing notch signaling. up-regulaton of this signaling pathway promotes tumorigenesis of multiple cancers.ro4929097 has shown potential antitumor activity both in vitro and in vivo. it impaired the growth of melanoma cell lines and tumor formation of human primary melanoma xenograft [2]. it slowed proliferation and reduces colony formation of breast cancer cell lines[1]. in addition, ro4929097 decreased tumor formation in xenograft models of colorectal, pancreatic, lung cancer and melanoma[1, 2]. ro4929097 has been tested in multiple phase i/ii
