Mechanism of action

Stimulates GH release via pituitary GHRH receptor. Albumin covalent binding extends plasma residence time.

Research context

CJC-1295 is a 30-residue GHRH analogue developed by ConjuChem. The DAC (Drug Affinity Complex) variant incorporates a maleimidopropionic acid linker enabling covalent binding to serum albumin, dramatically extending half-life relative to native GHRH.

Clinical development was discontinued; widely used in preclinical GH-axis research today.

FAQ

What is the difference between CJC-1295 with and without DAC?+

The DAC variant includes a maleimidopropionic acid (MPA) linker that covalently binds to serum albumin, extending plasma half-life to ~6–8 days. The non-DAC form has a half-life of ~30 minutes. Both are used in preclinical research.
