Adamax
PNC-27
Primary target
Melanocortin receptors (MC-Rs) in hippocampus and cortex
Membrane-bound HDM-2 protein on cancer cell surfaceSarafraz-Yazdi 2022Krzesaj 2024
Pathway
ACTH(4-10) fragment → MC-R binding → BDNF/trkB upregulation → neurotrophic signaling
PNC-27 binds to membrane HDM-2 1-109 domain → transmembrane pore formation → rapid necrosis (poptosis)Pincus 2024Krzesaj 2024
Downstream effect

Cardiovascular effects
ACTH(4-10) fragments may have pressor and cardioaccelerator actions at high dosesGruber 1984
Effects attenuated by α/β-receptor antagonists; observed at 30–1000 nmol/kg IV in rats.
—
Behavioral suppression
Suppression of aggression, reduced orientation-cognition reactions in rabbitsTeter 2001
May reflect anxiolytic or stress-dampening profile.

None available — no human trials conducted
Normal cell selectivity
—
In vitro: no cytotoxicity to normal cells (MCF-10-2A, peripheral blood mononuclear cells)Sarafraz-Yazdi 2010Thadi 2020
Normal cells express minimal membrane HDM-2.
Cancer cell specificity
—
Depends on membrane HDM-2 expression levels
Ovarian cancer lines with low membrane HDM-2 showed <30% necrosis.
Mitochondrial effects
—
Secondary mitochondrial membrane disruption in cancer cells
Absolute Contraindications
Adamax

—05Administration Protocol
Parameter
Adamax
PNC-27
1. Reconstitution (if lyophilised)
Add sterile water or bacteriostatic water to lyophilised vial per manufacturer guidance. Roll gently — do not shake. Ensure clarity before use.
PNC-27 has not been tested in human subjects. All data derive from in vitro cancer cell line studies and limited animal models. No approved clinical formulation, dosing protocol, or safety profile exists.Pincus 2024
2. Route
Intranasal administration is the primary route in animal and exploratory human studies. Delivered via nasal spray or dropper to ensure mucosal absorption.Dolotov 2006Smolnik 2000
In vitro studies used 10–100 μM PNC-27 dissolved in cell culture medium. Peptide was added directly to cancer cell cultures (pancreatic, breast, colon, ovarian, leukemia lines) and incubated for 24–72 hours.
3. Timing
Variable. Single-dose protocols for acute cognitive tasks; chronic daily dosing for circadian rhythm normalization and sustained neuroprotection.
Dual-labeled PNC-27 (green on N-terminus, red on C-terminus) demonstrated intact peptide binding to cancer cell membranes with combined yellow fluorescence at 30 minutes, persisting during cell lysis.Sookraj 2010
4. Storage
Lyophilised: room temperature, light-protected. Reconstituted: refrigerate 2–8 °C, use within manufacturer-specified timeframe.
Cytotoxicity correlates directly with membrane HDM-2 expression levels. Blocking HDM-2's p53-binding domain (1-109) with monoclonal antibodies prevents PNC-27-induced necrosis.
06Stack Synergy
Adamax
+ Semax
ModerateBoth Adamax and Semax are ACTH(4-10)-derived nootropics acting via melanocortin receptors and BDNF upregulation. Adamax has distinct amino acid modifications at positions 8-10, potentially offering complementary receptor binding profiles or metabolic stability. Stacking may amplify neurotrophic signaling and cognitive enhancement, though direct synergy studies are absent. Theoretical multi-pathway benefit.
