BPN 14770 Protocol: The PDE4 Pathway For Alzheimer

BPN-14770 is a novel compound currently under investigation for the treatment of Alzheimer’s disease and age-related cognitive decline. It works by targeting a specific enzyme pathway involved in memory and learning.


How It Works

BPN-14770 is a negative allosteric modulator of the PDE4 enzyme, with high selectivity for the PDE4D isoform. This enzyme is involved in the breakdown of cAMP, a key messenger molecule in the brain linked to:

  • Memory formation

  • Synaptic plasticity

  • Mood and motivation

By selectively modulating PDE4D, BPN-14770 aims to enhance cognitive function without the nausea often associated with non-selective PDE4 inhibitors.


Dosing Strategy

⚠️ Due to its investigational status and limited long-term safety data, BPN-14770 should be used conservatively and only for research purposes.

Level Total Daily Dose
Beginner 2.5–5 mg/day (can split dosing due to 10-hour half-life)
Intermediate 5–15 mg/day
Advanced 20 mg/day or more (higher doses should be approached with caution)

Pharmacokinetics

  • Half-life: ~10 hours

  • May be redosed later in the day for smoother cognitive effects, especially at lower doses.
