CJC-1295 With DAC

Buy CJC-1295 With DAC online | CJC-1295 With DAC for sale

CJC-1295 with DAC (Drug Affinity Complex) is a synthetic, long-acting analog of growth hormone-releasing hormone (GHRH). It is classified as a modified peptide hormone.

The compound is structurally derived from the first 29 amino acids of endogenous GHRH, with the addition of a maleimidopropionic acid (MPA) side chain. The side chain is known as the Drug Affinity Complex.

Researchers believe that DAC enables covalent binding to circulating serum albumin. This modification is of considerable preclinical interest due to the dramatically extended half-life it confers relative to unmodified GHRH analogs.

In preclinical models, CJC-1295 with DAC has been investigated for its role in modulating the hypothalamic-pituitary axis, specifically in the context of growth hormone secretion dynamics.

The DAC modification allows the peptide to resist enzymatic cleavage by dipeptidyl peptidase IV (DPP-IV). DPP-IV has made it a valuable investigational compound for researchers studying sustained GHRH receptor activity over extended timeframes.

Researchers study this compound for its potential research in endocrinology and metabolic essays.

Chemical and Molecular Properties

Proposed Working Mechanism of CJC-1295 with DAC

Preclinical studies suggest that CJC-1295 with DAC exerts its primary investigational effects through agonist binding at the GHRH receptor (GHRHR), a G protein-coupled receptor expressed on somatotroph cells of the anterior pituitary gland.

Upon receptor binding, research models indicate activation of the adenylyl cyclase–cAMP–PKA signaling pathway, which is associated with stimulation of growth hormone (GH) synthesis and pulsatile secretion in preclinical subjects.

The DAC modification introduces a unique pharmacokinetic profile. The maleimidopropionic acid moiety covalently conjugates with the cysteine-34 residue of endogenous serum albumin in preclinical models.

This albumin-binding mechanism effectively creates a circulating depot of the peptide to prolong receptor engagement and sustain elevated GH pulse amplitude.

Downstream from GHRHR activation, preclinical findings point to downstream effects on insulin-like growth factor 1 (IGF-1) secretion from hepatic research models.

Frequently Asked Questions

What is the significance of pulsatile growth hormone secretion in CJC-1295 with DAC research?

Pulsatile growth hormone secretion is considered an important component of normal somatotropic signaling regulation. Researchers investigate CJC-1295 with DAC in experimental models to better understand how sustained GHRH receptor stimulation may influence the timing, amplitude, and frequency of endogenous growth hormone release patterns over extended observation periods.

Why is albumin binding important in peptide-based research compounds?

Albumin binding is frequently studied because it may improve peptide stability and prolong systemic circulation time in biological environments. In the case of CJC-1295 with DAC, the albumin-binding mechanism has attracted research interest for its potential role in reducing enzymatic degradation and supporting sustained pharmacokinetic activity in preclinical models.

How is CJC-1295 with DAC utilized in endocrine signaling investigations?

Researchers commonly employ CJC-1295 with DAC in studies examining interactions between the hypothalamic-pituitary axis, growth hormone signaling pathways, and downstream endocrine mediators. Experimental investigations may focus on feedback regulation mechanisms, receptor activation patterns, and hormone-responsive cellular signaling processes.

What makes long-acting peptide analogs valuable in research environments?

Long-acting peptide analogs are often used in experimental settings where prolonged biological activity is desirable for observing signaling responses across extended timelines. CJC-1295 with DAC is frequently referenced in pharmacokinetic and endocrine research due to its sustained activity profile and relevance in long-duration peptide exposure studies.

What is the difference between CJC-1295 with DAC and CJC-1295 without DAC in preclinical research settings?

CJC-1295 with DAC contains the Drug Affinity Complex modification enabling covalent albumin binding, which extends functional half-life to approximately 6–8 days in investigational models. CJC-1295 without DAC (Modified GRF 1-29) has a half-life of approximately 30 minutes and produces discrete pulsatile GH release patterns. Researchers select between the two based on whether their protocol requires sustained GH elevation or biomimetic pulsatile secretion dynamics.
