Description

PQR620 is an orally bioavailable and selective brain penetrant inhibitor of mTORC1/2[1].

IC50 & Target

mTORC1/2[1]

In Vitro

PQR620 is a potent and selective mTOR inhibitor, which induces >1000-fold selectivity towards mTOR over PI3Kα in enzymatic binding assays. In A2058 melanoma cells PQR620 demonstrates inhibition of protein kinase B (pSer473) and ribosomal protein S6 (pSer235/236) phosphorylation with IC50 values of 0.2 μM and 0.1 μM, respectively. PQR620 shows excellent selectivity over a wide panel of kinases, as well as excellent selectivity versus unrelated receptor enzymes and ion channels. PQR620 demonstrates its potency to prevent cancer cell growth in an NTRC 44 cancer cell line panel, resulting in a 10log(IC50) of 2.86 (nM)[1]. PQR620 has a median IC50 of 250 nM when tested on 44 lymphoma cell lines. Activity is higher in B cell than in T cell tumors (median IC50s: 250 nM vs 450 nM; P=0.002). At 72h, anti-tumor activityof PQR620 is mostly cytostatic and apoptosis induction is seen only in 6/44 cell lines (13%). Sensitivity to PQR620 or apoptosis induction does not differ between DLBCL and MCL, and they are not affected by the DLBCL cell of origin, by TP53 status or by the presence of MYC or BCL2 translocations[2].

In Vivo

The physico-chemical properties of PQR620 result in good oral bioavailability and excellent brain penetration[1]. The activity of PQR620 as single agent undergoes in vivo evaluation in two DLBCL models, the germinal center B cell type DLBCL (GCB-DLBCL) SU-DHL-6 and the acivated B cell-like DLBCL (ABC-DLBCL) RIVA. Treatments with PQR620 (100 mg/kg dose per day, Qd×7/w) start with 100-150 mm3 tumors and are carried for 14 (SU-DHL-6) or 21 days (RIVA). In both models, PQR620 determines a 2-fold decrease of the tumor volumes in comparison with control, with significant differences in both SU-DHL-6 (D7, D9, D11, D14; P<0.005) and RIVA (D14, D16, D19, D21; P<0.005)[2].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.08 mg/mL (4.67 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.08 mg/mL (4.67 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
