Alzheimer’s disease is characterized by the degeneration of cholinergic neurons, which primarily driven acetylcholinesterase (AChE) enzyme and oxidative stress. This study investigated therapeutic potential cannabis-containing herbal remedy Suk-Saiyasna in alleviating amyloid β42 (Aβ42)-induced cytotoxicity SH-SY5Y cells. The DPPH radical-scavenging activity inhibitory effects on AChE were evaluated vitro. 167 ligands, including cannabinoids, flavonoids, terpenoids, alkaloids derived from Suk-Saiyasna, was assessed using ADMET analysis molecular docking techniques. results demonstrated that extract exhibited a radical scavenging effect with an IC50 value 27.40 ± 1.15 µg/mL notable 1.25 0.35 mg/mL. Importantly, at concentration 1 µg/mL, significantly protected cells Aβ42-induced stress compared to controls. Docking studies revealed delta-9-tetrahydrocannabinol (Δ9-THC), mesuaferrone B, piperine, β-sitosterol, chlorogenic acid substantial binding affinities AChE, surpassing reference drugs like galantamine rivastigmine. Furthermore, silico predictions indicated Δ9-THC piperine possessed favorable pharmacokinetic profiles, solubility, absorption, blood–brain barrier permeability, no neurotoxicity or carcinogenicity associated Δ9-THC.

Dihydroquercetin (DHQ) is a representative of flavonoids that available on the market as food supplement and registered an active pharmaceutical ingredient. The structure this compound characterized by presence two chiral centers in positions 2 3 pyranone ring. Current regulatory documentation DHQ lacks quantitative analysis stereoisomers flavanonol. This poses potential risks for consumers DHQ-based dietary supplements developers new drugs. review was conducted to systematize data pharmacology possible methods controlling them promising We found relying literature polarimetry identification currently impossible due these heterogeneities. NMR spectroscopy allows distinguishing between trans - cis -DHQ using chemical shifts values. Only HPLC sufficient enantioselectivity. Regarding pharmacology, most stereoisomer should be identified, if substituents both take part binding with biological target. significant impact stereochemical pharmacokinetics isomers reported. question about toxicity compounds remains open. results scientific indicate necessity revising taking into account its stereoisomerism.
