OTS514 (1.5625-100 nM) induces cell cycle arrest and apoptosis at nanomolar concentrations in a series of human myeloma cell lines (HMCL) and prevents outgrowth of a putative CD138+ stem cell population from multiple myeloma (MM) patient-derived peripheral blood mononuclear cells[2].

Cell Line:Human myeloma cell lines (MM1.S, MM1.R, RPMI 8226, 8226Dox40, KMS34, KMS34CFZ, KMS11, JJN3, LP-1, NCI H929, U266B1)
-
Concentration:1.5625, 3.125, 6.25, 12.5, 25, 50, and 100 nM
-
Incubation Time:72 hours
-
Result:IC50 values ranged from 11.6 to 29.4 nM in parental cell lines, indicating a potent inhibitory effect. Only the RPMI 8226-Dox40 cell line, which overexpresses the multi-drug resistance transporter gene ABCB1, was resistant.
