(c) Detection of development inhibition of TM-233 by MTS assay at a variety of doses (1, 2.5, five lM) and occasions (six h, black; 12 h dark gray; 24 h, light gray; 48 h, white) in myeloma cell lines. (d) U266 and RPMI8226 cells have been pre-treated with 25 ng / mL of interleukin-6 (IL-6) or vehicle for thirty min before remedy with numerous doses (0, two.5, 5 lM) of TM-233 and cell proliferation was detected by MTS assay. (e) Bone marrow samples from two myeloma patients (Pt 1 and Pt 2) had been sorted with CD138-beads and have been treated with either vehicle or 2.five lM of TM-233 for 24 h. Cell viability was measured by utilizing trypan blue exclusion. (f) Regular human peripheral blood mononuclear cells (PBMC) had been treated with low dose (two.five lM) and higher dose (10 lM) of TM-233 for 24 to 72 h. Viable cells were counted by using trypan blue exclusion. Asterisks (*) indicate P 0.05 versus handle.Cancer Sci | April 2015 | vol. 106 | no. 4 |2015 The Authors.

Mononuclear cells were separated by Lymphoprep (Nycomed Pharma, Oslo, Norway). CD138-positive plasma cells were sorted using MACS MicroBeads (Miltenyi Biotec, Tokyo, Japan). Normal human peripheral blood mononuclear cell (PBMC) have been purchased from Precision Bioservices (Frederick, MD, USA). Cells were maintained in RPMI-1640 culture medium (Sigma-Aldrich, St. Louis, MO, USA) supplemented with ten FBS (SigmaAldrich), 100 units / mL penicillin and one hundred mg / mL streptomycin within a humidified environment with five CO2. Morphology was examined on cytospin slides stained with Giemsa. Reagents. TM-233 (Fig. 1a, lower panel) is really a novel benzhydrol-type analog of ACA (ten -acetoxychavicol acetate) (Fig. 1a, upper panel), which we had previously created(14) and which was dissolved in DMSO at a stock concentration of ten mM. Interleukin-6 (IL-6) was purchased from Wako Pure Chemical Industries (Osaka, Japan). Assays for cellular viability and pr.
