One mechanism considered responsible for the hypercalcemia that frequently accompanies malignancy is secretion by the tumor of a circulating factor that alters calcium metabolism. The structure of a tumor-secreted peptide was recently determined and found to be partially homologous to parathyroid hormone (PTH). The amino-terminal 1-34 region of the factor(More)
As the use of high-throughput screening systems becomes more routine in the drug discovery process, there is an increasing need for fast and reliable analysis of the massive amounts of the resulting data. At the forefront of the methods used is data reduction, often assisted by cluster analysis. Activity thresholds reduce the data set under investigation to(More)
A public bacterial mutagenicity database was classified into 2-D structural families using a set of specific algorithms and clustering techniques that find overlapping classes of compounds based upon chemical substructures. Structure-activity relationships were learned from the biological activity of the compounds within each class and used to identify(More)
The relative order of activity of thyrotropin-releasing hormone (TRH) and various analogs in contracting the isolated guinea pig antrum and duodenum correlated with their potencies in activating thyroid-stimulating hormone (TSH) release. The action of TRH in both tissues was selectively antagonized by the putative pituitary TRH receptor antagonist,(More)
Leech antiplatelet protein (LAPP) is a specific inhibitor of collagen-induced human platelet aggregation and adhesion to collagen under static conditions. Recombinant LAPP (rLAPP) and L-366,763 (acetylated-Cys-Asn-Pro-Arg-Gly-Asp-Cys-NH2), a peptidyl fibrinogen receptor antagonist, were evaluated in an anesthetized baboon thrombosis model using a(More)
