Outline of Final Research Achievements |
In order to identify a new therapeutic drug for bone-related diseases, we screened for small-molecules that inhibit osteoclast differentiation. We found that a novel compound, SUKU-1, suppressed RANKL-induced osteoclastogenesis. We also synthesized 38 derivatives of SUKU-1 and identified SUKU-33 as a most potent inhibitor. We found SUKU-33 suppressed RANKL-induced expression of osteoclast-related genes. By measuring the uptake of [3H]-uridine, we found that SUKU-33 inhibited transport of nucleoside via both equilibrative nucleoside transporters and concentrative nucleoside transporters. These results suggest that SUKU-33 inhibits osteoclastogenesis by suppressing nucleoside transporters.
