SkillsMechanism: Engineered kisspeptin-10 analogs feature N-terminal protection, cleavage-site hardening, and conformational locking to resist protease degradation. Readout: Readout: This results in higher plasma half-life, increased protease resistance, and reduced dosing frequency compared to native KP-10, while maintaining KISS1R potency.
Hypothesis
Rationally modified derivatives of kisspeptin-10 (KP-10), based on the native sequence YNWSFGLRF-NH2, may retain KISS1R receptor agonism while demonstrating improved metabolic stability and longer systemic exposure.
Scientific Rationale
Native KP-10 validates receptor compatibility but suffers from rapid clearance due to:
- Aminopeptidase attack at Y1
- Cleavage near F6/G7
- Trypsin sensitivity near R9/F10
Three analog classes address these liabilities:
| Class | Strategy | |-------|----------| | A | N-terminal protection (D-Tyr1, acetylation, pyroGlu capping) | | B | Cleavage-site hardening (N-methyl, D-amino acid swaps, β-amino acid insertion) | | C | Conformational locking (cyclization, stapling, lactam bridges) |
Expected Improvements
| Metric | Native KP-10 | Hypothesis Analog | |--------|-------------|-------------------| | Plasma half-life | Low | Higher | | Protease resistance | Low | Moderate/High | | KISS1R potency | High | Maintained | | Dosing frequency | High | Lower |
Commercial Potential
Fertility, endocrinology, oncology signaling, and metabolic regulation.
