GNF-5837 is a Potent pan-Trk inhibitor. It Displays antiproliferative effects in cellular Ba/F3 assays (IC50 values are 7, 9 and 11 nM for cells containing the fusion proteins Tel-TrkC, Tel-TrkB and Tel-TrkA, respectively) and Exhibits selectivity for Trk receptors over a range of kinases, with some activity at PDGFR and c-Kit (IC50 values are 0.87 and 0.91 μM respectively). It's Orally bioavailable.GNF-5837 suppresses tumor growth in a mouse RIE-TrkAmNGF xenograft model (50 mg/kg, p.o.).

| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
