For evaluating the pressure responses of folded as well as intrinsically unfolded proteins detectable by NMR spectroscopy the availability of data from well-defined model systems is indispensable. In this work we report the pressure dependence of

Anti-inflammatory properties have been ascribed to a series of N-(fluorenyl-9-methoxycarbonyl) amino acids called leumedins that inhibit the activity of granulocytes and T-lymphocytes. We evaluated one of these leumedins, N-(fluorenyl-9-methoxycarbonyl) leucine (NPC 15199), in a model of ileitis in guinea pigs.

This report demonstrates that NPC-15199 [(N-(9-fluorenylmethoxycarbonyl)L-leucine)], a novel anti-inflammatory agent, increases intracellular Ca2+ concentration ([Ca2+]i) in human bladder female transitional cancer (BFTC) cells. Using fura-2 as a Ca2+ probe, NPC-15199 (0.1-2 mM) was found to increase [Ca2+]i concentration-dependently. The response
