SMI 4a|cas 438190-29-5, Synonym name: , Chemical name: 2,4-Thiazolidinedione, 5-[[3-(trifluoromethyl)phenyl]methylene]-, (5Z)-, Molecule weight: 273.23, Molecule Formula: C11H6F3NO2S
SMI-4a is a potent inhibitor of Pim1 with IC50 of 17 nM, modest potent to Pim-2, does not significantly inhibit other serine/threonine- or tyrosine-kinases.
SMI-4a is an ATP competitive inhibitor of Pim1 with IC50 of 17 nM. SMI-4a shows high selectivity for Pim1 against a panel of kinases. SMI-4a inhibits the in vitro phosphorylation by Pim-1 of the known substrate, the translational repressor 4E-BP1. SMI-4a (5μM) inhibits pancreatic and leukemic cells growth. SMI-4a reduces phosphorylation of the Pim target Bad in prostate and hematopoietic cells. SMI-4a causes cell cycle arrest and reverses the antiapoptotic activity of Pim-1. SMI-4a increases the amount of p27Kip1 in the nucleus.[1] SMI-4a treatment of pre-T-LBL inhibits the mTOR pathway. SMI-4a reduces MYC protein expression in pre-T-LBL. SMI-4a treatment induces up-regulation of MAPK pathway. [2] SMI-4a (60 mg/Kg) treatment twice daily significantly reduce tumor size and is well tolerated. Tumors harvested 1 hour after the final oral gavage of SMI-4a demonstrates decreased phosphorylation of p70 S6K compared with tumors from mice treated with vehicle, whereas in comparison total p70 S6K expression isunchanged.
