Gonadorelin
Summary
PNC-27 is a synthetic peptide derived from the p53 tumor suppressor protein, containing both an HDM2-binding domain and a transmembrane penetratin sequence. It selectively kills cancer cells by binding MDM2/HDM2 overexpressed on the plasma membrane of malignant cells, inducing membranolysis without harming normal cells.
Gonadorelin is the synthetic form of endogenous GnRH (gonadotropin-releasing hormone). It stimulates the pituitary to release LH and FSH, maintaining testicular function and testosterone production. Widely used alongside TRT to prevent testicular atrophy and preserve fertility.

Key Benefits
  • Selective cytotoxicity against cancer cells overexpressing HDM2/MDM2
  • Spares normal cells lacking surface HDM2 expression
  • Membranolytic mechanism bypasses intracellular resistance pathways
  • Demonstrated activity against breast, pancreatic, leukemia, and melanoma cell lines
  • Potential for combination with conventional chemotherapy
  • Novel non-genotoxic anticancer mechanism
  • Maintains testicular size during TRT
  • Preserves fertility and sperm production during testosterone use
  • Stimulates endogenous LH/FSH production
  • Maintains HPG axis function during exogenous hormone use
  • Used for HCG-free TRT protocols
  • Helps restart natural testosterone production (PCT)
Side Effects
  • Limited human clinical data; largely in vitro and animal studies
  • Potential immunogenic reactions (foreign peptide)
  • Systemic toxicity at high doses not well characterized
  • Unknown interactions with current chemotherapy agents
  • Injection site reactions
  • Headache
  • Nausea at initiation
  • Tachycardia (rare)
