体外研究

PIM-447 (0.05-10 µM; 24, 48 and 72 hours)has inhibitory effects in MM cells, it against sensitive cell lines with IC ₅₀ values ranging from 0.2 to 3.3 µM (MM1S, MM1R, RPMI-8226, MM144, U266 and NCI-H929) and less sensitive cell lines with IC ₅₀ values at 48 h >7 µM (OPM-2,RPMI-LR5, U266-Dox4 and U266-LR7).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.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.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.

Cell Viability Assay

Cell Line:	Sensitive MM cell lines: MM1S, MM1R, RPMI-8226, MM144, U266 and NCI-H929 cells Less sensitive MM cell lines: OPM-2,RPMI-LR5, U266-Dox4 and U266-LR7cells
Concentration:	0.05-10 µM
Incubation Time:	24, 48 and 72 hours
Result:	Was cytotoxic for MM cells (PIM kinases highly expressed).

Apoptosis Analysis

Cell Line:	Sensitive MM cell lines: MM1S, NCI-H929 and RPMI-8226 cells Less sensitive MM cell lines: OPM-2 and RPMI-LR5 cells
Concentration:	0.05-10 µM
Incubation Time:	24, 48 and 72 hours
Result:	Induced cell apoptosis at higer doses, had no effects at 0.1-1 uM.

Western Blot Analysis

Cell Line:	Sensitive MM cell lines: MM1S, NCI-H929 and RPMI-8226 cells
Concentration:	0.05-10 µM
Incubation Time:	24, 48 hours
Result:	Increased the cleavage of the effector caspases 3 and 7, and the PARP cleavage.

Cell Cycle Analysis

Cell Line:	MM1S, OPM-2 cells
Concentration:	0.1, 0.5 or 1 µM
Incubation Time:	48 hours

体内研究

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.

Animal Model:	RPMI-8226-luc cells are injected intravenously into 6-week-old female NODSCID-IL-2Rγ ^-/- (NSG) mice
Dosage:	100 mg/kg
Administration:	oral gavage; 100 mg/kg; 5 times/week
Result:	Was well tolerated, as the body weight of mice did not decrease by more than 10%. Increased bone volume density and trabecular number and reduced trabecular separation relative to vehicle group.
