Abstract: The present invention relates generally to phosphoinositide 3-kinases (PI3Ks), and more particularly to specific, selective, improved PI3K? inhibitors and methods of inhibiting undesirable levels of PI3K? activity using these PI3K? inhibitors to treat disorders mediated by PI3K?.

Abstract: The invention relates generally to phosphoinositide 3-kinases (PI3Ks), and more particularly to methods of inhibiting leukocyte accumulation comprising selectively inhibiting phosphoinositide 3-kinase delta (PI3K?) and phosphoinositide 3-kinase gamma (PI3K?) activities in endothelial cells. The disclosed methods may be used to treat individuals having an inflammatory condition where leukocytes are found to be accumulating at the site of insult or inflamed tissue. The inflammatory condition may be attributed to or associated with an underlying disorder not typically associated with inflammation, e.g. cancer, coronary vascular disease, etc.

Abstract: Disclosed are novel seven transmembrane receptor polypeptides having characteristic extracellular structure including lectin-binding, olfactomedin-like and mucin-like domains.

Abstract: This invention relates to method and reagents for inhibiting furin endoprotease activity and specifically for inhibiting furin endoprotease-mediated maturation of bioactive proteins in vivo and in vitro. The invention specifically provides proteins capable of inhibiting furin endoprotease activity. Particularly provided are .alpha..sub.1 -antitrypsin variants that specifically inhibit furin endoprotease activity. Methods for using furin endoprotease inhibition to attenuate or prevent viral protein maturation, and thereby alleviate viral infections, are provided. Also provided are methods for using furin endoprotease inhibition to attenuate or prevent proteolytic processing of bacterial toxins, thereby alleviating bacterial infections. Methods are also provided to inhibit proteolytic processing of biologically active proteins and peptides. The invention also provides pharmaceutically acceptable compositions of therapeutically effective amounts of furin endoprotease inhibitors.
