Abstract: A class of substituted azetidine, pyrrolidine and piperidine derivatives of Formula I are selective agonists of 5-HT.sub.1 -like receptors, being potent agonists of the human 5-HT.sub.1D.alpha. receptor subtype whilst possessing at least a 10-fold selective affinity for the 5-HT.sub.1D.alpha. receptor subtype relative to the 5-HT.sub.1D.beta. subtype; they are therefore useful in the treatment and/or prevention of clinical conditions, in particular migraine and associated disorders, for which a subtype-selective agonist of 5-HT.sub.1D receptors is indicated, whilst eliciting fewer side-effects, notably adverse cardiovascular events, than those associated with non-subtype-selective 5-HT.sub.1D receptor agonists.

Abstract: Chemical conjugates which comprise oligopeptides, having amino acid sequences that are selectively proteolytically cleaved by free prostate specific antigen (PSA) and known cytotoxic agents are disclosed. The conjugates of the invention are characterized by a diamine linker between the oligopeptide and vinblastine. Such conjugates are useful in the treatment of prostatic cancer and benign prostatic hypertrophy (BPH).

Abstract: A immunoassay based on the detection of leukocyte-elastase produced fibrinogen cleavage peptides which allows the evaluation of the potency of compounds that inhibit formation of cleavage peptides in a variety of in vitro cell biological situations is provided. The assay may be employed to detect an endogenous leukocyte-elastase produced fibrinogen cleavage peptide signal in normal human plasma and at elevated levels in cystic fibrosis plasma and in rheumatoid arthritis synovial fluid samples. The assay procedure can be a single step assay which allows for the rapid and reproducible detection of specific cleavage peptides.
