Jr. Tagat et al., SYNTHETIC INHIBITORS OF INTERLEUKIN-6 .1. YL-1H-CYCLOPENT[E]IMIDAZO[1,2-A]-PYRIDIN-5(6H)-ONE AND RELATED-COMPOUNDS, Bioorganic & medicinal chemistry letters, 5(18), 1995, pp. 2139-2142
A versatile synthetic route to the title class of compounds and the de
velopment of an orally absorbed analogue of the lead structure are des
cribed. The minimum structural requirements needed in the compounds re
lated to 1 for the inhibition of interleukin-6 were identified.
