Synthesis and pharmacological evaluation of 1,1,3-substituted urea derivatives as potent TNF-α production inhibitors

Add time:09/24/2019    Source:sciencedirect.com

A three substituted urea derivative, SA13353 (compound 1a), exhibited potent inhibitory activity against lipopolysaccharide (LPS)-induced TNF-α production. We focused on the 1,1-substituted moiety (R1 and R2) of SA13353 and investigated substituent effects of this moiety on LPS-induced TNF-α production by oral administration in rats. The synthesis of the urea derivatives was performed rapidly in a one-pot manner using a manual synthesizer. Several compounds containing hydrophobic substituents at this moiety showed more potent inhibitory activities than SA13353.
