SST-VEDI-1(VEDI-1) is a new synthetic compound that is synthesized from tryptamine, and has structural similarity to the SSH-BM family of compounds. However, the biological effects of VEDI-1 have yet to be well characterized. A recent report has demonstrated that SSH-BM-type compounds can stimulate osteoblast activity in cultured scales of goldfish. In this study, we examined the effects of VEDI-1 on osteoblastic differentiation as well as its effects on apoptosis, which is known to be closely related to osteoblastic differentiation. We found that VEDI-1 enhanced the formation of mineralized nodules in rat osteoblast cell lines, including ROS17/2.8 cells, and in mouse pre-osteoblast cell lines, including MC3T3-E1 cells, in a dose dependent manner, which was accompanied by increased expression of late osteoblast markers, bone sialoprotein (BSP) and osteocalcin (OC). Furthermore, VEDI-I inhibited apoptotic cell death and regulated the expression of proteins in the Bcl-2 family. These results suggest that VEDI-1 may facilitate late differentiation of osteoblasts and may have an inhibitory effect on apoptosis.

MS-IPA1 is a new synthetic compound that is synthesized from tryptamine. Recently, our group demonstrated that SST-VED-I-1, which has a similar chemical structure to MS-IPA1, inhibits starvation-induced apoptosis in osteoblasts. However, the effects of MS-IPA1 on apoptosis in osteoblasts have not yet been examined. Therefore, this study examined the effects of this compound on apoptosis in osteoblasts. In this study, MC3T3-E1 mouse osteoblasts were used and apoptosis was induced by ultraviolet radiation (UV). We investigated the effect of MS-IPA1 on apoptosis by analyzing caspase3/7 activity, translocation of phosphatidylserine (PS), and mRNA expression levels of Bcl-2 and Bax. In addition, it was investigated whether MS-IPA1 affects cell proliferation and cell cycle progression. We found that MS-IPA1 had no effect on cell proliferation or cell cycle progression. However, MS-IPA1 suppressed UV-induced cell death in a dose-dependent manner, which was accompanied with the inhibition of caspase activation and translocation of PS. Furthermore, after UV exposure, Bcl-2 expression was increased in the MS-IPA1-treated cells as compared to that in the vehicle-treated cells. In contrast, Bax expression was decreased in the MS-IPA1-treated cell as compared to that in the vehicle-treated cells. These results suggest that MS-IPA1 has an inhibitory effect on apoptosis in osteoblasts through a Bcl-2 family-dependent signaling pathway.
