生物活性

Selitrectinib (LOXO-195) is a next-generation TRK kinase inhibitor, with IC50s of 0.6 nM and <2.5 nM for TRKA and TRKC, respectively[1].

IC50 & Target

TrkA

0.6 nM (IC50)

TrkC

<2.5 nM (IC50)

体外研究
(In Vitro)

Selitrectinib (LOXO-195) demonstrates strong binding to the wild-type TRKA, TRKB and TRKC kinase domains. Selitrectinib (LOXO-195) has potent (IC50<1 nM) inhibitory activity in kinase enzyme assays. Importantly, Selitrectinib (LOXO-195) achieves low nanomolar inhibitory activity against TRKA G595R, TRKC G623R, and TRKA G667C, with IC50s ranging from 2.0-9.8 nM. 228 individual kinases in vitro are profiled at a Selitrectinib (LOXO-195) concentration of 1 μM, which is ~1667-fold higher than its IC50 for TRKA (0.6 nM). Selitrectinib (LOXO-195) is more than 1000-fold selective for 98% of non-TRK kinases tested. Selitrectinib (LOXO-195) demonstrates potent inhibition of cell proliferation in TRK fusion-containing KM12, CUTO-3, and MO-91 cell lines (IC50≤5 nM)[1].

体内研究
(In Vivo)

Stably transfected NIH-3T3 ΔTRKA and ΔTRKA-G595R cells are implanted subcutaneously into the flanks of nude mice. Both larotrectinib and Selitrectinib (LOXO-195) are effective at reducing phosphorylated TRKA in tumors driven by ΔTRKA. In contrast, only Selitrectinib (LOXO-195) strongly suppresses phospho-TRKA in ΔTRKA-G595R cells in a dose-dependent manner. Selitrectinib (LOXO-195) also causes inhibition of tumor growth relative to vehicle at all doses in four TRKA-dependent tumor models (ΔTRKA, ΔTRKA-G595R, ΔTRKAG667C, and TPM3-NTRK1 fusion-positive KM12 colorectal cancer cells. Larotrectinib inhibits KM12 and NIH 3T3-ΔTRKA tumors to a similar degree. Group mean body weight loss does not exceed 5% for any agent. Selitrectinib (LOXO-195) displays high selectivity for the TRK proteins[1]

Cell Assay
[1]

For assessment of cellular inhibition potency, cells are harvested per a standard protocol, counted and added to flat-bottom, collagen I-coated 96-well assay plates at 3×104 cells/well (wild-type cell line) or 5×104 cells/well (mutant cell lines) in 100 μL/well of DMEM growth medium containing 10% FBS. Plates are then incubated at room temperature for 30 minutes prior to an overnight incubation at 37°C with 5% CO2. Next, cells are treated for 1 hour at 37°C, 5% CO2 with TRK inhibitor compounds (e.g., Selitrectinib (LOXO-195)). Control wells contain either 0.25% DMSO alone or 1 μM larotrectinib or LOXO-195. Following compound incubation, growth medium is discarded and cells are lysed by addition of 60 μL/well of ice-cold lysis buffer containing protease and phosphatase inhibitors[1].

Animal Administration
[1]

Mice[1]
The ΔTRKA, ΔTRKA-G595R, and ΔTRKA -G667C NIH-3T3 tumor cell lines (~2-3x106 cells) and KM12 cells (5x106 cells) are injected subcutaneously into the right flank of female nu/nu NCr mice. Tumors are allowed to grow to ~100-200 mm3 or ~500 mm3, and animals are randomized by tumor size into dosing groups of 5 (KM12), 7 (NIH 3T3 ΔTRKA variants) or 3-4 (for PK-PD) animals. Animals are dosed by oral gavage with vehicle, Selitrectinib (LOXO-195) in 1% carboxymethylcellulose/0.5% Tween-80 or larotrectinib in 100% Labrafac lipophile. All animals are obtained at 6-8 weeks of age, housed in groups of 5 and allowed a one-week acclimation period before cancer cell injection. Animals are dosed with vehicle twice daily, Selitrectinib (LOXO-195) at 30 mg/kg, 100 mg/kg and 300 mg/kg twice daily and larotrectinib at 60 mg/kg daily for 9-12 days. Body weight and tumor size are monitored after cell implantation and at regular intervals during dosing[1].

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.
