Water-soluble discrete multi-biotin-containing compounds with at least three (3) biotin moieties are disclosed. The water-soluble biotin-containing compounds may additionally comprise one or more moieties that confer resistance to cleavage by biotinidase or that is cleavable in vitro or in vivo. The discrete multi-biotin-containing compounds may include a reactive moiety that provides a site for reaction with yet another moiety, such as a targeting, diagnostic or therapeutic functional moiety. Biotinylation reagents comprising water-soluble linker moieties are also disclosed and may additionally comprise a biotinidase protective group. Methods for amplifying the number of sites for binding biotin-binding proteins at a selected target using multi-biotin compounds also are disclosed.

teilgeschützten Derivate mit tert.-Butyloxy-carbonylazid führt bei kontrolliertem pH in guten Ausbeuten zu den tert.-Butyloxycarbonyl-Derivaten. Auch sterisch gehinderte Aminosäuren reagieren glatt. Durch die Wahl der pH-Werte lassen sich die günstigsten Bedingungen für eine rasche und weitgehende Umsetzung bequem ermitteln.
Isoquinolinylguanidine compounds of formula (I): ##STR1## wherein the substituents are as defined herein, and salts thereof, are disclosed as urokinase inhibitors.
A pharmaceutical for use in damaged tissue, such as wound, treatment (e.g. healing) is described. The pharmaceutical comprising a composition which comprises: (a) a growth factor; and (b) an inhibitor agent; and optionally (c) a pharmaceutically acceptable carrier, diluent or excipient; wherein the inhibitor agent can inhibit the action of at least one specific adverse protein (e.g. a specific protease) that is upregulated in a damaged tissue, such as a wound, environment.
