A series of N-carboxy, N-alkyl, and N-carboxamido azabicyclo[2.2.2]octane carboxamides were prepared and assayed for inhibition Of alpha(4)beta(1)-VCAM-1 and alpha(4)beta(7)-MAdCAM-1 interactions. Potency and alpha(4)beta(1)/alpha(4)beta(7) selectivity were sensitive to the substituent R-1-R-3 in the structures 6, 7, and 8. Several compounds demonstrated low nanomolar balanced alpha(4)beta(1)/alpha(4)beta(7) in vitro activity. Two compounds were selected for in vivo leukocytosis studies and demonstrated increases in circulating lymphocytes up to 250% over control. (c) 2005 Elsevier Ltd. All rights reserved.
