KU-55933 Inibitore di ATM

N. Cat.: S1092

KU-55933 è un potente e specifico inibitore di ATM con IC50/Ki di 12,9 nM/2,2 nM in saggi acellulari, ed è altamente selettivo per ATM rispetto a DNA-PK, PI3K/PI4K, ATR e mTOR. KU‑55933 (Inibitore della chinasi ATM) inibisce l'attivazione della chinasi ULK1 che inizia l'autofagia e provoca una significativa diminuzione dell'autofagia.

Meccanismo d'azione (Mechanism of Action)

Targets/IC50/Ki
ATM
(Cell-free assay)
12.9 nM
In vitro
KU-55933 inhibits DNA-PK and PI3K with IC50 of 2.5 μM and 16.6 μM, respectively. Besides, this compound also prevents the activity of mTOR with IC50 of 9.3 μM. It is active at the cellular level in ablating a well-characterized ATM-dependent phosphorylation event. This chemical has a dose-dependent effect in inhibiting this ATM-dependent phosphorylation event with IC50 of 300 nM. KU-58050 does not prevent the ATM-dependent phosphorylation of p53 serine 15 until a dose of 30 μM. Addition of this compound has no appreciable effects on UV-induced phosphorylation of H2AX on serine 139, NBS1 on serine 343, CHK1 on serine 345, and SMC1 on serine 966. In stark contrast to the UV responses, it ablates the ionizing radiation-induced phosphorylation of these ATM substrates. This chemical sensitizes HeLa cells to a range of ionizing radiation doses. It inhibits the phosphorylation of Akt induced by growth factors in cancer cells. This compound suppresses the proliferation of cancer cells. Furthermore, suppression of ATM by this chemical improves survival, probably via prevention of downstream activation of TAp63α.
Saggio chinasico
Saggi enzimatici purificati
L'ATM da utilizzare nel saggio in vitro è ottenuta dall'estratto nucleare di HeLa mediante immunoprecipitazione con antisiero policlonale di coniglio elevato contro i 400 amminoacidi COOH-terminali di ATM in un tampone contenente 25 mM HEPES (pH 7.4), 2 mM MgCl2, 250 mM KCl, 500 μM EDTA, 100 μM Na3VO4, 10% v/v glicerolo e 0.1% v/v Igepal. I complessi ATM-anticorpo sono isolati dall'estratto nucleare incubando con perle di proteina A-Sepharose per 1 ora e poi mediante centrifugazione per recuperare le perle. Nel pozzetto di una piastra a 96 pozzetti, le perle di Sepharose contenenti ATM vengono incubate con 1 μg di substrato glutatione S-transferasi–p53N66 (66 amminoacidi NH2-terminali di p53 fusi alla glutatione S-transferasi) in tampone di saggio ATM [25 mM HEPES (pH 7.4), 75 mM NaCl, 3 mM MgCl2, 2 mM MnCl2, 50 μM Na3VO4, 500 μM DTT e 5% v/v glicerolo] a 37 °C in presenza o assenza di questo composto. Dopo 10 minuti con agitazione delicata, l'ATP viene aggiunto a una concentrazione finale di 50 μM e la reazione continua a 37 °C per un'altra ora. La piastra viene centrifugata a 250 × g per 10 minuti (4 °C) per rimuovere le perle contenenti ATM, e il surnatante viene rimosso e trasferito in una piastra opaca bianca a 96 pozzetti e incubato a temperatura ambiente per 1.5 ore per consentire il legame della glutatione S-transferasi-p53N66. Questa piastra viene quindi lavata con PBS, asciugata e analizzata mediante una tecnica ELISA standard con un anticorpo anti-p53 fosfo-serina 15. La rilevazione del substrato glutatione S-transferasi-p53N66 fosforilato viene eseguita in combinazione con un anticorpo secondario di capra anti-topo coniugato con perossidasi di rafano. Una soluzione di chemiluminescenza potenziata viene utilizzata per produrre un segnale e viene eseguita la rilevazione chemiluminescente.
In vivo
Suppression of ATM-dependent STAT3 activation by KU-55933 enhances TRAIL-mediated apoptosis through up-regulation of surface DR5 expression, whereas suppression of both STAT3 and NF-κB appeares to be involved in down-regulation of cFLIP accompanied by an additional increase in apoptotic levels. This compound affects TRAIL-mediated apoptosis more strongly than the JAK2 inhibitor, AG490, or overexpression of STAT3β.
