Patent number: 6462179Abstract: Reagents suitable for the modification of a bioactive species for the purpose of incorporating one or more phenyldiboronic acid (PDBA) moieties for subsequent conjugation to a different (or the same) bioactive species having one or more pendant boronic compound complexing moieties of the general formula of General Formula I, wherein group R is a reactive electrophilic or nucleophilic moiety suitable for reaction of the PDBA reagent with a bioactive species. Group Z is a spacer selected from a saturated or unsaturated chain up to about 0 to 6 carbon equivalents in length, an unbranched saturated or unsaturated chain of from about 6 to 18 carbon equivalents in length with at least one intermediate amide or disulfide moiety, and a polyethylene glycol chain of from about 3 to 12 carbon equivalents in length. Group Q is a linkage that includes one of amide, ether and thioether moieties.Type: GrantFiled: July 25, 2000Date of Patent: October 8, 2002Assignee: Prolinx, Inc.Inventors: Mark L. Stolowitz, Edward A. Kesicki, Kevin P. Lund, Karin A. Hughes
