In Vitro

In vitro activity: CZ415 shows no genotoxic potential and has very good cell permeability. Treatment of CZ415 leads to inhibition of phosphorylation for downstream targets of mTORC1 and mTORC2(IC50=14.5 nM for pS6RP and IC50=14.8 nM for pAKT). The immunosuppressive effect of CZ415 is measured by detecting secreted IFNγ after 18 h in stimulated human whole blood, and the resulting IC50 was 226 nM. CZ415 shows no genotoxic potential. It is neither mutagenic in a bacterial mutation assay (Ames test) nor does it show genotoxicity in the mouse lymphoma assay (MLA), in either the presence or absence of rat-liver S9 mix.

Kinase Assay: IC50 & Target: 14.5 nM (pS6RP), 14.8 nM (pAKT), 226 nM (IFNγ)

Cell Assay: Cells are seeded in 90 μL DMEM containing 2% FCS at 4x104 cells/well (for pS6RP S240/244 assay) or 8x104 cells/well (for pAKT S473 assay) in a 96well U-bottom plate. The plate is then incubated for 1h in a humidified incubator (37oC, 5% CO2) to allow cells to adhere. CZ415: 3 μM start, 8 points 1:3 dilution steps, n=2. Positive control: 1 μM PI-103 (n=8). Negative control: DMSO (n=8). 10 μL of 10x compound concentration in 1% DMSO/99% (DMEM 2% FCS) are added to the cells followed by 2 h incubation in a humidified incubator (37oC, 5% CO2). Cells are lysed by addition of 10 μL 5x Complete Lysis Buffer and gentle shaking at 4°C for 15 min.

In Vivo

In vivo studies show that CZ415 has moderate clearance and good oral bioavailability. In an anti-CD3 mouse model CZ415 efficiently inhibits mTOR downstream signaling and, in a CIA mouse model, shows significant antiinflammatory effects. With its extraordinary selectivity, drug-like properties and proven efficacy in vivo, CZ415 represents an ideal molecule for the pharmacological investigation of mTOR pathophysiological role in vivo.
