PIM447 dihydrochloride (LGH447 dihydrochloride) is a potent, orally available, and selective pan-PIMkinase inhibitor, withK_ivalues of 6, 18, and 9 pM forPIM1,PIM2, andPIM3, respectively. PIM447 dihydrochloride displays dual antimyeloma and bone-protective effects. PIM447 dihydrochloride inducesapoptosis^[1][2].

Ki: 6 pM (PIM1); 18 pM (PIM1); 9 pM (PIM3)^[1]

PIM-447 (0.05-10 μM; 24, 48 and 72 hours) has inhibitory effects in MM cells, it against sensitive cell lines with IC₅₀values ranging from 0.2 to 3.3 μM (MM1S, MM1R, RPMI-8226, MM144, U266 and NCI-H929) and less sensitive cell lines with IC₅₀values at 48 h >7 μM (OPM-2, RPMI-LR5, U266-Dox4 and U266-LR7)^[1].
PIM-447 (0.1-10 μM; 24, 48 and 72 hours) does not induce important levels of apoptosis, when PIM447 at 5 μM, it substantially increases annexin-V levels (about 30%) in sensitive cell lines(MM1S, NCI-H929 and RPMI-8226). When PIM447 at 10 μM, it induces apoptosis in all the cell lines but to a lesser extent in OPM-2 and RPMI-LR5^[1].
PIM447 promotes the cleavage of initiator caspases, such as caspases 8 and 9, and increases the cleavage of the effector caspases 3 and 7, together with PARP cleavage in MM1S,RPMI-8226 and NCI-H929 cells^[1].
PIM447 (0.1-1 μM) increases the percentage of cells in the G0/G1 phase and decreases the proliferative phases (S and G2/M) of the cell cycle. The effects at low concentrations (0.1-1 μM) were more pronounced in MM1S cells than in OPM-2^[1].

PIM447 (oral gavage; 100 mg/kg; 5 times/week) clearly controlls tumor progression and the serum levels of hIgλ secreted by RPMI-8226-luc cells in mouse model of bone marrow-disseminated human multiple myeloma^[1].
