STF 083010 Chemical Properties,Usage,Production
Description
STF-083010 (307543-71-1) is a novel small molecule inhibitor of IRE1. It inhibits IRE1 endonuclease activity but not its kinase activity after endoplasmic reticulum stress.1-3 It displays significant antimyeloma activity in model human MM xenografts.1?STF-083010 induces apoptosis in pancreatic cancer cells and displays growth inhibition in a clonogenic growth assay in soft agar as well as in a xenograft?in vivo model of pancreatic cancer.4?Active?in vivo.
Uses
STF 083010 is an inhibitor of Ire1 endonuclease.
Uses
STF-083010 has been used:
- in a study to investigate the?potential?anti-lipotoxic effect of nicotinamide and to elucidate underlying mechanism(s)
- as IRE1a inhibitor to study its effect on NOS 2 expression and investigate the underlying mechanisms in proinflammatory gene expression in astrocytes
- to block endogenous XBP1 cleavage for one hour prior to palmitate exposure in order to examine whether inositol?requiring enzyme 1α (IRE1α ) activation is implicated in palmitate cytotoxicity
Biochem/physiol Actions
STF-083010 is a potent inhibitor of the ER transmembrane protein IRE1, which mediates the unfolded protein response. STF-083010 inhibits IRE1 endonuclease and mRNA splicing activity in response to endopasmic reticulum (ER) stress, but has no affect on the kinase activity of IRE1.
in vitro
after endoplasmic reticulum stress both in vitro and in vivo, stf-083010 prevented ire1 endonuclease activity without affecting its kinase activity. treatment with stf-083010 exhibited significant antimyeloma activity in model human mm xenografts. similarly, compared with other similarly isolated cell populations, stf-083010 was preferentially toxic to freshly isolated human cd138 mm cells. on basis of the identification of this novel ire1 inhibitor, propose that the ire1-xbp1 axis is a promising target for anticancer therapy (especially in the context of mm) [1].
in vivo
the small molecule stf083010, identified by a high-throughput screen of compounds affecting ire1 activity, was capable of directly inhibiting the endonuclease function of ire1 without affecting its kinase activity. after treatment of mice harboring subcutaneous xenografts led to tumor shrinkage and multiple myeloma cells harvested from cancer patients died following exposure to stf083010, the antimyeloma therapeutic potential of stf083010 was convincingly demonstrated [2].
