The effects of a novel anti-inflammatory agent, 5-methoxy-3-(1-methyl-ethoxy)benzo[b]thiophene-2-carboxamide-1-oxide (PD 144795) on adhesion molecule expression in tumor necrosis factor (TNF) stimulated human aortic endothelial cells (HAEC) were examined. PD 144795 treatment markedly inhibited the TNF-induced cell expression of vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) protein and mRNA. Gel shift assays using nuclear extracts from HAEC treated with PD 144795 failed to show a decrease in the activation of NFkB by this compound, whereas pyrrolidine dithiocarbamate (PDTC), an antioxidant, markedly inhibited the activation of this transcription factor. Thus, PD 144795 inhibits agonist-stimulated VCAM-1 and ICAM-1 expression likely via an NFkB independent mechanism, distinct from that of PDTC. Such agents may provide a novel approach for control of adhesion molecule gene expression in inflammation.Copyright 1995, 1999 Academic Press. Inc. |
