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.).

|Cell Lines||C57BL/6J mice|
|Results||As a positive control, we demonstrated that pretreatment with GNF-5837 inhibited NGF-induced thermal hyperalgesia|
|Body Surface Area (m2)||0.007||0.025||0.15||0.05||0.02||0.5|
|Animal A (mg/kg) = Animal B (mg/kg) multiplied by||Animal B Km|

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 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 resveratrol of 11.2 mg/kg.
