Three alkoxyalkyl 2-carboxylate ester derivatives related to zanamivir were synthesized. All of the analogs of zanamivir modified at carboxylic moiety with alkoxyalkyl esters 1a-c showed higher activities than ribavirin on influenza A and B virus in the MDCK cells. Oral treatment or intraperitoneal administration of compound 1c showed significantly(More)
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.(More)
A novel series of 1-(benzo[b]thiophen-2-yl)ethanone analogues were prepared and evaluated for enhancing BMP-2 expression. Compounds 1-5, 7, 8, 12, 13 and 16, with upregulation rate values of 35.6%, 27.9%, 39.8%, 32.0%, 37.1%, 30.2%, 28.0%, 33.5%, 22.8% and 27.3% in vitro, respectively, at a concentration of 4muM, exhibited potent effect for enhancing BMP-2(More)
