Signaling Pathways & Laboratory Handling Protocols

Documented Receptor Pathways & In Vitro Signaling

1

Selective binding to pituitary somatotroph GHRH receptors, stimulating adenylate cyclase and cAMP pathways.

2

Promotion of physiologic pulsatile endogenous growth hormone secretion while preserving negative feedback loops.

3

Sustained stimulation of hepatic insulin-like growth factor 1 (IGF-1) transcription.

4

Preservation of pituitary responsiveness without downregulating prolactin or cortisol receptor selectivity.

Investigation Scope

Investigated in kinetic trials both with Drug Affinity Complex (DAC) and without DAC. Evaluated in human clinical kinetic trials for somatotroph secretagogue profiles.
