Reported findings and study design
OGP and Pepcan-12 were used to model a proposed allosteric binding site on CB2. Screening 56 peptides yielded five candidates. Pep-5, the best-performing new candidate, inhibited cAMP accumulation with an EC50 of 6.0 micromolar and enhanced the effect of WIN55,212-2 in the cell assay.
| Measure | Result | Comparison, timing and statistics |
|---|---|---|
| Screening | 56 peptides → 5 candidates | |
| Pep-5 functional potency | EC50 6.0 micromolar | Pep-5 cell assay; NOT an OGP potency estimate |
| OGP contribution | Modeled CB2 allosteric binding | Docking and molecular dynamics, not a clinical experiment |
The measured 6.0 micromolar potency belongs to Pep-5, not OGP. OGP binding was computationally modeled. The proposed binding site and new candidate do not establish a treatment effect in people.
