In vivo LY2874455 exhibits a potent inhibition of FGF-induced Erk phosphorylation in the heart tissues of mice with TED50 and TED90 values of 1.3 and 3.2 mg/kg, respectively. In mice bearing RT-112, OPM-2 (DSMZ), SNU-16, or NCI-H460 xenograft, LY2874455 (3 mg/kg p.o.) results in dose-dependent inhibition of the tumor growth. [1]

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
