Substituted Benzothiophene or Benzofuran Derivatives as a Novel Class of Bone Morphogenetic Protein-2 Up-Regulators: Synthesis, Structure−Activity Relationships, and Preventive Bone Loss Efficacies in Senescence Accelerated Mice (SAMP6) and Ovariectomized Rats
摘要:
In this work, substituted benzothiophene and benzofuran compounds were found to be a new class of potential anabolic agents by enhancing BMP-2 expression. A series of benzothiophene and benzofuran derivatives have been synthesized, and their activities of up-regulating BMP-2 and bone loss prevention efficacies in SAMP6 mice and OVX rats have been studied. Benzothiophenes 1, 3, 14, 4a, 7a, 8a, and benzofuran analogue 2 showed higher BMP-2 up-regulation rates in vitro. Compound 8111 was found to significantly affect the bone formation rate of tested SAMP6 mice. Compound I showed an improved bone quality in SAMP6 mice and also showed activity in OVX rats. We have demonstrated that Substituted benzothiophene and benzofuran derivatives, especially compounds I and 8a, enhance BMP-2 expression in vitro and in vivo and stimulate bone formation and trabecular connectivity restoration ill vivo. The compounds represent potential leads in the development of a new class of anabolic agents.
