N-(1-phenylethyl)-2-(pyrrolidin-1-yl)quinazolin-4-aMine Chemical Properties,Usage,Production
Description
Importazole is a cell-permeable inhibitor of importin-β, which transports cargo molecules bearing a nuclear localization signal into the nucleus. Importazole prevents nuclear import of GFP-tagged nuclear factor of activated T cells (NFAT-GFP) in HEK293 cells (IC50 = 15 μM), which is reversible upon importazole washout. Importazole does not interfere with transportin-mediated nuclear import or chromosomal maintenance 1 (CRM1)-mediated nuclear export. Importazole inhibits nuclear import of topoisomerase IIβ binding protein 1 (TopBP1) in Xenopus egg extracts and of NF-κB in multiple myeloma cells. It also induces defects in spindle and microtubule formation in vitro.
Uses
Importazole has been used:
- to inhibit importin-β and to elucidate the mechanism of enhanced nuclear localization of heat shock protein 70 (HSP70) by vaccinia-related kinase 3 (VRK3)
- to treat COS?7 cells transfected with the expressing vectors of WT HNF4α , S78A, and S78D to study its effect
- as a KPNB inhibitor to determine whether CREB-regulated co-activator 1 (CRTC1) would be escorted into the nucleus by the classical nuclear localizing sequence (NLS)- dependent machinery
- as a functional inhibitor of Importin β in embryo treatment
- as an?importin?inhibitor to treat the transfected H1299 cells to block nuclear translocation of phosphorylated p53-RS
Uses
Importazole is an importin-β inhibitor.
Definition
ChEBI: N-(1-phenylethyl)-2-(1-pyrrolidinyl)-4-quinazolinamine is a member of quinazolines.
Biochem/physiol Actions
Importazole is an inhibitor of importin-β transport receptors. During interphase, the transport receptor importin-β carries cargoes into the nucleus, where RanGTP releases them. Importazole somehow disrupts the importin/RAN interaction. Importazole is selective among other transporters. Compounds are imported into, but not out of, cells.
