01Mechanism of Action

Parameter
PTD-DBM
Tesofensine
Primary target
CXXC5–Dishevelled protein-protein interaction
Serotonin / norepinephrine / dopamine transporters (SERT / NET / DAT)Astrup 2008
Pathway
Inhibit CXXC5 binding to Dishevelled → Release Wnt/β-catenin pathway inhibitionLee 2015Ryu 2023
Triple monoamine reuptake inhibition → ↑synaptic 5-HT, NE, DA → appetite suppression + thermogenesisAstrup 2008
Downstream effect
Activated Wnt/β-catenin signaling promotes hair follicle regeneration, dermal stem cell activation, reduced myofibroblast differentiation
Strong appetite suppression, mild thermogenic effect, weight lossAstrup 2008
Feedback intact?
Not applicable — pathway derepression rather than receptor agonism
Origin
Engineered fusion: cell-penetrating PTD sequence + Dvl-binding motif targeting CXXC5
Small molecule developed by NeuroSearch (Denmark) for CNS indications, repurposed for obesityAstrup 2008
Antibody development

05Administration Protocol

Parameter
PTD-DBM
Tesofensine
1. Wound Healing Protocol (Animal Model)
Pyrogallol-functionalized hyaluronic acid (HA-PG) hydrogel patch loaded with PTD-DBM peptide, applied directly to wound bed. Adhesive hydrogel provides sustained release over multiple days.Lee 2023
Oral capsule (investigational; not commercial).
2. Hair Regeneration Protocol (Animal Model)
Topical application to scalp or wound site. Precise formulation not disclosed; studies used Cxxc5 knockout or direct peptide application in wound-induced hair neogenesis models.Ryu 2023
Swallow whole with water, morning only.
3. Combination Therapy
PTD-DBM + valproic acid (GSK-3β inhibitor) in HA-PG patch showed synergistic effect on scar reduction and regenerative wound healing. VPA enhances Wnt pathway activation downstream.Lee 2023
Morning to mitigate insomnia. Do not dose evening.
4. Storage & Handling
Not disclosed in available literature. Peptide stability and storage conditions not published.
Room temp ≤25 °C, dry place.
5. Caveat
Monitor BP + HR + mood. Avoid stimulants + MAOIs.
