- the compound 1-16 was dissolved in dimethylsulfoxide (DMS ⁇ ) to prepare a 20 mmol ZL solution of each compound. It was further diluted with DMSO to prepare 6, 2, 0.6, and 0.2 mmol / L solutions of each compound. Each of the prepared concentrations (0.2 to 20 mmol / L), a DMSS solution of each compound (116), or DMSO (as a group to which no conjugate was added) was added to a medium (10% fetal bovine serum). FBS) supplemented RPMI-1640 medium) and diluted 1000-fold, and 0 (non-supplemented group), 0.2, 0.6, 2, 6, 20 zmol / L of each compound (1-6) Solutions were each prepared.
- DMS ⁇ dimethylsulfoxide
- a 2 ⁇ 10 5 cellsZmL cell suspension of RPMI8226 cells was prepared and seeded at 2 mL each in a 6-well plate.
- each well After the culture, the cells in each well were collected, the number of cells was counted for each well, and each was again prepared as a suspension of 2 ⁇ 10 5 cells / mL. The seeds were inoculated at 0.5 mL each.
- each solution corresponding to the same concentration as in the above culture (concentration 0 (non-addition group) of compound 16), 0.2, 0.6, 2, 6, 20 Ai mol / L
- Each solution was prepared in the same manner as in the previous culture, added to each well in an amount of 0.5 mL, and mixed, and then cultured at 37 ° C in the presence of 5% CO for 3 days as a late culture.
- the culture supernatant was collected for each well, and the ⁇ PN concentration in the culture supernatant was measured by ELIS A method (Human Osteopontin measurement kit IBL, Immune Biological Laboratory Co., Ltd.). It was quantified using a photometer.
- the obtained measured values were analyzed by the following procedure using the SAS preclinical package Version 5.0. That is, the concentration was converted to a logarithm (the compound-free group (0 ⁇ mol / L) was replaced with lpmol / L), and the measured values (6 concentrations, 2 measured values for each concentration, 12 measured values in total) were used. Fitting to the dystic curve was performed. From the obtained curve, the concentration at which the reaction rate is 50% ( IC) was calculated. Table 1 shows the results.
