[Image: see text] Historically, modulation of transforming growth factor β (TGF-β) signaling has been deemed a rational strategy to treat many disorders, though few successful examples have been reported to date. This difficulty could be partially

Acetals are the most useful protecting groups for carbonyl functional groups. In addition to the role of protection, they can also be used as synthons of carbonyl functions. Previously, we developed a chemoselective deprotection and nucleophilic subs

A mild and divergent route for the synthesis of alkyl ethers from methoxymethyl (MOM) and methoxyethyl (ME) ether derivatives via pyridinium-type salt intermediates has been developed. The addition of organocuprates to the salts afforded the correspo

Methoxymethyl or 1-methoxyethyl ether derivatives are transformed by a one-pot two-step sequence into the corresponding alkyl ether derivatives via pyridinium salt intermediates, which are added to organocuprates generated in situ from CuI and alkyl/

We previously demonstrated that tumor necrosis factor (TNF)-α stimulated the production of activation protein (AP)-1, a transcriptional factor, in mouse osteoblastic MC3T3-E1 cells. Recent studies have shown the importance of ceramide and its metabo
