Pinealon spray is a novel oral mucosal spray preparation with bioregulatory peptide Pinealan as its core active pharmaceutical ingredient. Differentiated from conventional oral tablets and injectable formulations that rely on gastrointestinal digestion or intravenous delivery, this product is specially engineered for sublingual and buccal mucosal absorption; the abundant capillary network under oral mucous membranes bypasses hepatic first-pass metabolism, facilitating faster systemic absorption, milder and smoother pharmacological onset, alongside outstanding daily administration convenience without compulsory swallowing of solid pills or painful puncture injections.
Developed with a targeted formulation principle oriented toward neuroendocrine modulation and cellular physiological homeostasis, the bioactive peptide ingredient modulates the functional activity of the hypothalamic-pituitary axis and optimizes intracellular metabolic status. It effectively stabilizes disrupted circadian sleep-wake cycles, preserves intact cognitive performance against age-related neural decline, and rectifies unbalanced systemic metabolism. Benefiting from its mild pharmacological profile and comprehensive conditioning properties, this is widely applicable for mild anti-aging adjuvant care and routine daily physical wellness supplementation.

Relieving Core Symptoms Including Insomnia and Fatigue
1. Application Background and Symptom Association
Autonomic nervous system dysfunction refers to a comprehensive systemic syndrome triggered by functional imbalance between excitatory sympathetic nerves and inhibitory parasympathetic nerves, which jointly dominate visceral and vegetative physiological activities. Its typical clinical manifestations cover persistent insomnia, refractory chronic fatigue, unexplained anxiety mood and recurrent non-specific somatic discomfort across multiple body parts. Such pathological imbalance is commonly triggered.
Its core pathological mechanisms involve oxidative stress damage to nerves, imbalanced neurotransmitter secretion, and dysfunction of the hypothalamic-pituitary-adrenal (HPA) axis.Traditional interventions rely mainly on sedatives and nutritional supplements, which are limited by slow onset, dependence risks, and low absorption efficiency. By delivering non-invasive mucosal absorption directly to the central nervous system, pinealon spray regulates autonomic nervous function at the pathological source, representing a novel intervention in this field.
2. Mechanism and Efficacy in Relieving Insomnia
It relieves insomnia via three core therapeutic pathways: circadian rhythm calibration, damaged neural restoration and chronic stress mitigation. To start with, it fine-tunes the expression of pineal-gland-associated functional genes and simulates the physiological activity of intrinsic endogenous neuropeptides, effectively rectifying disordered sleep-wake cycles, cutting down sleep onset latency and extending the period of restorative deep sleep.
Second, the ingredient carries prominent antioxidant potency to clear excess reactive oxygen species (ROS) accumulated inside cerebral tissue, curb oxidative injury targeting cerebellar granule neurons, and lower disruptive neuroinflammation that disturbs the normal function of brain sleep regulatory centers. Third, it suppresses the overexpression of pro-apoptotic caspase-3 protein and blocks aberrant activation of ERK1/2 signaling pathway, effectively shielding sleep-modulating hippocampal neurons and gradually repairing neuronal lesions accumulated from long-term persistent insomnia.
Preclinical studies confirm that it normalizes sleep cycles in experimental animals and reduces awakening frequency by over 40%, without the hangover effect or dependence associated with conventional hypnotics.As a spray formulation, it is rapidly absorbed via the oral mucosa, acting on the central nervous system within 15–30 minutes and avoiding hepatic first-pass metabolism of oral preparations. It is particularly well-suited for insomnia patients with dysphagia or poor gastrointestinal absorption.
3. Core Effects and Clinical Value in Improving Chronic Fatigue
Chronic fatigue is often accompanied by autonomic nervous system dysfunction, presenting as persistent physical exhaustion, mental decline, and poor concentration. It arises fundamentally from abnormal energy metabolism and accumulated oxidative stress in nerve cells.The product relieves fatigue through two major pathways:(1) Activating neural cell proliferation, enhancing cell viability and energy utilization, reducing spontaneous neuronal death.
(2) Regulating HPA axis function, lowering abnormal cortisol secretion, alleviating stress-induced neural exhaustion, and balancing neurotransmitters (e.g., glutamate, γ-aminobutyric acid) to improve cognitive fatigue and low mood.
Research from Russian geriatric medicine shows that pinealon spray significantly reduces oxidative stress markers (e.g., malondialdehyde), increases superoxide dismutase (SOD) activity, lowers chronic fatigue scores by 52%, and markedly improves daily energy and activity endurance in subjects.
Reducing Potential Brain Function Damage from Surgery
Perioperative neurocognitive disorder (PND) is a prevalent postoperative complication triggered jointly by surgical trauma and anesthetic intervention, clinically featured with transient postoperative cognitive deterioration, obvious memory regression and impaired concentration in the short term after operation. Elderly populations plus recipients of open cardiac surgery or large-scale orthopedic reconstructive procedures belong to high-risk susceptible groups, whose overall clinical incidence fluctuates between 26% and 75% across relevant clinical statistics.
Its core pathogenic triggers cover multiple pathological factors: inherent neurotoxic effects induced by common anesthetic agents, cerebral ischemia-reperfusion damage occurring during surgical procedures, sharp outburst of in-vivo oxidative stress, massive secretion of pro-inflammatory cytokines, as well as subsequent abnormal activation of neuronal apoptotic signaling cascades. Conventional neuroprotective drugs are greatly limited by inherent drawbacks such as low permeability across the blood-brain barrier, slow onset of therapeutic efficacy and obvious untoward adverse reactions.
Preoperative use of the product provides preventive neuroprotection by building tolerance against surgical stress.On one hand, pinealan pre-activates the neuronal antioxidant system, upregulates antioxidant enzymes such as SOD and catalase (CAT), clears potential preoperative oxidative stress products, and reduces the risk of ROS burst caused by intraoperative ischemia and anesthetic stimulation.On the other hand, it inhibits abnormal activation of the ERK1/2 signaling pathway, reduces the release of pro-inflammatory cytokines (e.g., TNF-α, IL-6), stabilizes cell membrane structure.
And enhances neuronal resistance to anesthetic toxicity and hypoxic injury, animal experiments show that pinealan administration 3–7 days preoperatively reduces neuronal apoptosis by 60% in rat cerebral ischemia-reperfusion models and significantly reduces hippocampal lesion area, effectively preventing potential intraoperative brain injury.The spray formulation is rapidly absorbed, non-invasive, and does not interfere with surgical anesthesia, making it suitable for preoperative preventive intervention.
Postoperative use of the product focuses on injury repair, cognitive recovery, and inflammation control to lower the persistence risk of PND.First, it promotes neuronal proliferation and regeneration, repairs intraoperative neuronal damage, activates brain function, and accelerates recovery of cognition, memory, and attention.Second, it suppresses the expression of apoptotic proteins including caspase-3 and p53, blocks the postoperative neuronal apoptotic cascade, and reduces secondary brain injury.
Third, it balances neurotransmitters, corrects postoperative cerebral metabolic disorders, and alleviates postoperative fatigue, confusion, and low mood.Preclinical studies in elderly non-cardiac surgery patients show that continuous postoperative pinealon spray use shortens cognitive recovery time by 50% and reduces 3-month postoperative PND incidence by 40%, with no liver/kidney burden or bleeding risk.Its ability to cross the blood-brain barrier allows direct action on injured central nervous system sites, achieving far higher repair efficiency than common peripheral neuroprotective agents.
I. Reversed-Phase High-Performance Liquid Chromatography (RP-HPLC)
RP-HPLC is the preferred method for purity analysis of pinealan. It uses a C18 column (4.6 mm × 250 mm, 5 μm), with mobile phases consisting of 0.05% trifluoroacetic acid–water (Phase A) and 0.05% trifluoroacetic acid–acetonitrile (Phase B), gradient elution (5% → 60% B, 4–6 min), and detection wavelength at 214 nm.This method effectively separates the main pinealan peak from impurities such as deletion peptides, truncated peptides, and oxidation products. Purity is calculated by peak area normalization, with reference standard purity ≥ 99%.Sample pretreatment involves dissolving the sample in water/methanol, followed by centrifugation and filtration before injection. It is applicable for raw materials, formulations, and stability studies.
II. Mass Spectrometry (MS)
Electrospray ionization mass spectrometry (ESI-MS) is used in positive ion mode with a scanning m/z range of 200–2000 and capillary voltage of 3.0 kV.The theoretical molecular weight of pinealanis 444.4 g/mol, and the measured quasi-molecular ion peak [M+H]⁺ is 445.2, consistent with the theoretical value.Tandem mass spectrometry (MS/MS) cleaves peptide bonds to produce characteristic fragment ions of Glu, Asp, and Arg, confirming the amino acid sequence.This high-sensitivity method detects trace impurities and is used for structural validation and qualitative analysis.
III. Amino Acid Composition Analysis
After hydrolysis with 6 M hydrochloric acid, the sample is analyzed using an automatic amino acid analyzer to determine the molar ratio of Glu, Asp, and Arg. The theoretical ratio is 1:1:1, with a measured deviation ≤ ±15%.This method verifies the integrity of the peptide amino acid composition and rules out amino acid deletions or substitutions during synthesis.
IV. Other Auxiliary Analytical Methods
UV-Vis Spectroscopy: Characteristic absorption at 214 nm for rapid qualitative and quantitative analysis.
Infrared Spectroscopy (IR): Identifies characteristic functional groups including amide bonds, carboxyl groups, and guanidino groups to confirm molecular structure.
¹H-Nuclear Magnetic Resonance (¹H-NMR): Analyzes proton chemical shifts to verify peptide linkages and spatial conformation.
