Description: Selective and reversible p97 ATPase inhibitor
Chemical Name: N2,N4-Bis(phenylmethyl)-2,4-quinazolinediamine
Purity: ≥99% (HPLC)
Biological Activity for DBeQ
DBeQ is a selective and reversible inhibitor of p97 ATPase (VCP, IC50 = 1.5 μM). Induces executioner caspases (caspase-3 and caspase-7) rapidly. Blocks the degradation of endoplasmic reticulum-associated degradation (ERAD) reporters; also blocks autophagosome maturation and promotes accumulation of LC3-II.
Compound Libraries for DBeQ
DBeQ is also offered as part of the Tocriscreen 2.0 Max. Find out more about compound libraries available from Tocris.

DbeQ on Dictyostelium mTORC1 signalling.
By
Eleanor Warren on 05/23/2019
Assay Type: In Vitro
Species: Other
Treated Dictyostelium cells with DbeQ at 15 uM and 1.5 uM concentrations for 1 hour or 24 hours, and monitored p-4E-BP1 levels as a readout for mTORc1 activity. Did not see any significant difference from control
