Verkningsmekanism (Mechanism of Action)

Egenskaper
A first-in-class proteasome inhibitor that has improved pharmacokinetics (PK), pharmacodynamics(PD), and antitumor activity in preclinical studies.

In vitro
At higher concentrations, this compound also inhibits the caspase-like (β1) and trypsin-like (β2) proteolytic sites with IC50 of 31nM and 3.5uM, respectively. It inhibits Calu-6 cell with IC50 of 9.7 nM. MLN2238 is a selective, potent, and reversible inhibitor of the proteasome in tumor cells. This compound shows time-dependent reversible proteasome inhibition. Both this compound and Bortezomib shows time-dependent reversible proteasome inhibition; however, the proteasome dissociation half-life for it is determined to be ∼6-fold faster than that of Bortezomib (18 and 110 minutes, respectively). It dissociates more rapidly from the proteasome than Bortezomib, consistent with faster recovery of proteasome activity observed in the Proteasome-Glo assay. It has a greater overall tumor pharmacodynamic effect than Bortezomib as assessed by 20S inhibition. This compound is the biologically active form of MLN9708.
Kinasanalys
Kinassanalys
Calu-6-celler odlas i MEM som innehåller 10 % fetalt bovint serum och 1 % penicillin/streptomycin och plattas ut 1 dag före experimentets början med 1 × 104 celler per brunn i en 384-brunnsplatta. Proteasome-aktivitet bedöms genom att övervaka hydrolysen av det kymotrypsinliknande substratet Suc-LLVY-aminoluciferin i närvaro av luciferas med hjälp av Proteasome-Glo-analysreagens enligt tillverkarens instruktioner. Luminescensen mäts med ett LEADseeker-instrument.
In vivo
MLN2238 induces a greater pharmacodynamic response than Bortezomib in xenograft tumors. This compound shows greater maximum and sustained tumor proteasome inhibition compared with Bortezomib in xenograft models. These results confirm that the improved tumor exposure seen with this agent translates into an improved tumor pharmacodynamic response both at the level of and downstream from the proteasome. It shows antitumor activity in the CWR22 xenograft model. This chemical shows greater tumor pharmacodynamic responses in WSU-DLCL2 xenografts compared with Bortezomib. Similarly, Bortezomib treatment only led to a minor increase in GADD34 levels in WSU-DLCL2 xenograft tumors, whereas it strongly induces its expression. This compound has an improved pharmacodynamic profile and antitumor activity compared with Bortezomib in both OCI-Ly10 and PHTX22L models.
