Rheb inhibitor NR1

Research use only, not for human use.

Rheb inhibitor NR1 is a selective mTORC1 inhibitor that suppresses the phosphorylation of T389pS6K1 and enhances the phosphorylation of S473pAKT.

Rheb inhibitor NR1 is a Rheb inhibitor with an IC50 of 2.1?μM in the Rheb-IVK assay. Rheb inhibitor NR1 can directly bind Rheb in the switch II domain and selectively inhibit the activation of mechanistic target of rapamycin complex 1 (mTORC1). Rheb inhibitor NR1 inhibits the phosphorylation of mTORC1 driven T389pS6K1 and increases the phosphorylation of S473pAKT in a dose-dependent manner. Rheb inhibitor NR1 does not influence mTORC2 activity.(Rheb-IVK:Rheb-dependent mTORC1 kinase activity)

Cell Viability Assay Cell Line:Jurkat cells Concentration:1, 3 and 10 μM Incubation Time:48 h Result:Effectively reduced the size of Jurkat cells in a dose-dependent manner.Western Blot Analysis Cell Line:MCF-7, TRI102 and PC3 cells Concentration:0.37, 1.1, 3.3, 10 and 30 μM Incubation Time:90 min for MCF-7 and TRI102; 24 h for PC3 Result:Inhibited the phosphorylation of T389pS6K1 and increased the phosphorylation of S473pAKT in a dose-dependent manner.Western Blot Analysis Cell Line:MCF-7 Concentration:1, 3, 10 and 30 μM Incubation Time:2.5 h (then labeled the cells with an 35S-Met labeling mix for 30?min)Result:Dose-dependently reduced protein synthesis.

Animal Model:Male C57BL/6 mice (6-7 weeks; fast for 16 hours) Dosage:30 mg/kg Administration:IP; single dosage Result:Sustained over 5?μM for 2?h.Significantly reduced mTORC1 activity in both kidney and skeletal muscle, and exhibited a clear band shift for T37/464E-BP1 in skeletal muscle.
