An Aldehyde Responsive, Cleavable Linker for Glucose Responsive Insulins

A glucose responsive insulin (GRI) that responds to changes in blood glucose concentrations has remained an elusive goal. Here we describe the development of glucose cleavable linkers based on hydrazone and thiazolidine structures. We developed linkers with low levels of spontaneous hydrolysis but increased level of hydrolysis with rising concentrations of glucose, which demonstrated their glucose responsiveness in vitro. Lipidated hydrazones and thiazolidines were conjugated to the LysB29 side-chain of HI by pH-controlled acylations providing GRIs with glucose responsiveness confirmed in vitro for thiazolidines. Clamp studies showed increased glucose infusion at hyperglycemic conditions for one GRI indicative of a true glucose response. The glucose responsive cleavable linker in these GRIs allow changes in glucose levels to drive the release of active insulin from a circulating depot. We have demonstrated an unprecedented, chemically responsive linker concept for biopharmaceuticals.

α-Amino ketone derivatives

The invention concerns α-aminoacyl derivatives of phenyl-, phenoxy-, thiophenoxy- and phenylsulphinylalkanoic acids together with their amides, esters and pharmaceutically acceptable salts; processes for their preparation; and pharmaceutical compositions for therapeutic use in inhibiting the formation of thrombi and also in reducing the persistence of thrombi formed in the blood of warm blooded animals. Representative compounds of the invention are methyl 4-(aminoacetyl)phenoxyacetate, 4-(aminoacetyl)phenoxyacetic acid and methyl 4-(aminoacetyl)-thiophenoxyacetate, preferably as their hydrochlorides.
