in this study, we investigated a series of fast-acting insulin analogues, ias, derived from the endogenous insulin pro-b29 (p29) which has been shown to display a faster onset and shorter duration of action in animal models. against this background, a paired comparison of nine humanized analogues, including a naturally purified b29-(p29) analogue, was performed in recombinant insulin-secreting cell models. only one analogue, aspart b29-tyrb31-tyrb32-serb30-thrb29-prob27-glnb28-ileb26-ileb25-leub24-pheb23-leub22-leub21-leub20-leub19-leub18-leub17, displayed a speed of action equivalent to that of human insulin, as assessed by a new insulin secretion threshold-sensitive intracellular calcium-influx assay, whereas all other analogues showed significantly slowed insulin secretion kinetics.

data indicate that the intrinsically faster insulin kinetics of b29-(p29)-derived insulin analogues are maintained after humanization and thus constitute a valuable addition to insulin therapy. the analogue, sb2922, was selected for further investigations in a series of short- and long-term in vivo studies in dogs and humans.
sb2922 has shown superior glycemic control to human insulin in dogs with normal and elevated glucose tolerance, with equivalent insulin efficacy. in human trials, a single bolus injection of sb2922 was fully effective in a cgm-controlled meal test with the known onset of action of human insulin. subsequent studies have further demonstrated the therapeutic effect of sb2922 in type 2 diabetes, insulin resistance, and obesity.
[18f]ge-ipa-d2a-klaklak was successfully synthesized in 47min from eob and the radioactive conjugate was obtained with a molar activity of 68.447gbq/mol and a decay corrected yield of 5.18%. in serum stability studies, the conjugate was found to be stable over the three-hour incubation period, while in filter stability studies the percentage of intact conjugate was found to be 75% after 2 hours
