CH5183284

Biological Activity

In vitro: In cell-based assay, CH5183284 prevents autophosphorylation of FGFR1, FGFR2, and FGFR3 at 100 to 300 nM in the DMS114 (FGFR1 amplification), SNU-16 (FGFR2 amplification), and KMS11 [t(4;14) translocation and FGFR3 Y373C mutation] cell lines. CH5183284 thus produces selective antiproliferative activity against cancer cell lines harboring genetic alterations in FGFR. CH5183284 also inhibit FGFR2 harboring one type of the gatekeeper mutation (V564F) that causes resistance to other FGFR inhibitors. In vivo: CH5183284 (100 mg/kg/day, p.o.) shows selective and significant antitumor activity against xenografts with FGFR genetic alterations such as KG1 (leukemia, FGFR1OP-FGFR1 fusion), SNU-16 (gastric cancer, FGFR2 amplification), MFE-280 (endometrial cancer, FGFR2 S252W mutation), UM-UC-14 (bladder cancer, FGFR3 S249C mutation), and RT112/84 (bladder cancer, FGFR3-TACC3 fusion).

Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)

Species	Mouse	Rat	Rabbit	Guinea pig	Hamster	Dog
Weight (kg)	0.02	0.15	1.8	0.4	0.08	10
Body Surface Area (m2)	0.007	0.025	0.15	0.05	0.02	0.5
Km factor	3	6	12	8	5	20

Animal A (mg/kg) = Animal B (mg/kg) multiplied by	Animal B Km
	Animal A 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 K_m factor for a mouse and then divide by the K_m factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
