GNF-7 is the first type II inhibitors capable of inhibiting T315I to be described and will serve as a valuable lead to design next generation Bcr-Abl kinase inhibitors. GNF-7 inhibits Bcr-Abl WT and Bcr-Abl T315I with IC50 of 133 nM and 61 nM, respectively. GNF-7 exhibits some selectivity (4 to 100-fold) for T315I Bcr-Abl (IC50 = 11 nM, in Ba/F3 cell line) relative to kinases such as TPR-Met, NPM-ALK, JAK-3, Flt-3. In vivo, GNF-7 displays significant efficacy against T315I-Bcr-Abl without appreciable toxicity in a bioluminescent xenograft mouse model using a transformed T315I-Bcr-Abl-Ba/F3 cell line that has a stable luciferase expression.

| 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.
