A three substituted urea derivative, SA13353 (compound 1a), exhibited potent inhibitory activity against lipopolysaccharide (LPS)-induced TNF-alpha production. We focused on the 1,1-substituted moiety (R(1) and R(2)) of SA13353 and investigated substituent effects of this moiety on LPS-induced TNF-alpha 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. (C) 2010 Elsevier Ltd. All rights reserved.
