KPV — pharmacology
Molecular targets, mechanism of action, pharmacokinetics and interactions as characterised in humans.
§2Pharmacology
§2.1Molecular targets
Table 2. Molecular targets recorded for KPV, with the character of the interaction and the potency where the Institute holds it.
| Target | Interaction | Note |
|---|---|---|
| Mechanism partially characterised | Melanocortin-receptor-independent | Anti-inflammatory activity persists in melanocortin receptor knockout models, indicating a distinct pathway; NF-κB inhibition and PepT1-mediated epithelial uptake have been reported |
§2.2Mechanism of action
KPV inhibits NF-κB activation and reduces pro-inflammatory cytokine production in epithelial and immune cells. Reported uptake through the intestinal peptide transporter PepT1 provides a plausible route for local action in intestinal epithelium after oral administration, which is the most mechanistically coherent application described for it.[1,2]
§2.3Pharmacokinetics
No human pharmacokinetic characterisation of KPV has been identified. In the absence of a half-life, a volume of distribution and a clearance estimate, no dosing interval used in practice can be related to any exposure that produced an effect in any study, and the Institute records this as a first-order gap rather than a detail.
§2.4Interactions
- Not characterised
