TH9507

TH9507 (Tesamorelin) Research Standard

TH9507 (Tesamorelin) is a synthetic 44-amino acid analog of endogenous growth hormone–releasing hormone (GHRH). Engineered with structural modifications to enhance stability and resistance to enzymatic degradation, it functions as a potent GHRH receptor (GHRH-R) agonist. In laboratory research, TH9507 is utilized to stimulate endogenous, pulsatile growth hormone (GH) secretion via the anterior pituitary. It serves as a precise chemical probe for investigating the dynamics of the hypothalamic–pituitary–somatotropic axis and the physiological regulation of endocrine feedback loops.

Technical Specifications

Mechanism of Action & Research Context

TH9507 is designed to engage the pituitary gland’s native signaling machinery, mimicking the action of endogenous GHRH.

• GHRH-R Agonism: As a specific agonist, TH9507 binds to the GHRH receptor on pituitary somatotrophs. This interaction triggers the activation of the cAMP/PKA signaling cascade.

• Physiologic Pulsatility: Unlike exogenous GH administration, TH9507 stimulates the body’s own GH production, which helps preserve the natural, pulsatile rhythm of hormone release. This makes it an ideal model for studying the regulation of endogenous hormone production.

• Feedback Engagement: The peptide is utilized to observe how the hypothalamic–pituitary–somatotropic axis responds to GHRH-R stimulation, including the operation of native negative feedback mechanisms.

Research Applications

TH9507 is a specialized reagent essential for endocrine and neuro-metabolic research.

Primary fields of in vitro and in vivo laboratory investigation include:

• GH Axis Regulation: Measuring pituitary responsiveness to modified GHRH analogs in isolated cell culture models.

• Endocrine Feedback Loops: Studying the modulation of hormone release within controlled feedback circuits.

• Metabolic Signaling: Probing the downstream effects of pituitary-derived GH on systemic metabolism and tissue repair pathways.

• Comparative GHRH Studies: Serving as a comparative benchmark when evaluating the potency, stability, or signaling efficiency of different GHRH analogs and growth hormone-releasing peptides (GHRPs).

Storage & Handling Guidelines

To maintain the chemical stability and experimental reliability of the peptide:

• Storage Environment: Keep the lyophilized powder in a dry, cool environment. Maintain at temperatures below 0°C (typically -20°C) for long-term stability.

• Light Sensitivity: Protect strictly from direct light to prevent the degradation of the peptide sequence.

• Reconstitution: Use sterile, buffered aqueous solutions for reconstitution. Aliquot the solution immediately after preparation to minimize freeze-thaw cycles.

• Aseptic Technique: Handle with clean, sterile laboratory equipment in a controlled environment to prevent enzymatic or microbial contamination.
