ADMET informatics of Plant Derived n-Hexadecanoic Acid (Palmitic Acid) from ethyl acetate fraction of Moringa oleifera leaf extract

Palmitic Acid (PA) is known to exert multiple fundamental biological functions at cellular and tissue levels and its steady concentration is guaranteed by its endogenous synthesis by DNL. PA has been for a long time negatively represented for its detrimental health effects tailing its essential physiological attributes. PA has been portrayed to serve as a signalling molecule regulating the progression and development of many diseases at molecular level. Controversial data on the association of dietary PA with detrimental health effects has been related to several parameters such as fatty acid/ macronutrient imbalance by altered lipid metabolism, positive energy balance, excessive intake of carbohydrates, imbalance of dietary PA/PUFA, physiopathological conditions, presence of enhanced DNL and sedentary lifestyle. This may result in dyslipidemia, hyperglycemia, increased ectopic fat accumulation and increased inflammatory tone indicating that clear understanding of system based PA metabolism is still lacking. In the present study an attempt has been made to bring out the absorption, distribution, metabolism, elimination and toxicity profile of PA. Results are expected to have some implications in elucidating the molecular mechanisms that regulates pathophysiological events involved in hyperglycemia/ hyperlipidemia-induced complications associated with diabesity and CVD. Besides it may provide a better understanding to identify key molecular targets for therapeutic management of PA induced metabolic disorders.

ADMET informatics of Tetradecanoic acid (Myristic Acid) from ethyl acetate fraction of Moringa oleifera leaves

In-silico Computer-Aided Drug Design (CADD) often comprehends virtual screening (VS) of datasets of natural pharmaco-active compounds for drug discovery protocols. Plant Based Natural Products (PBNPs) still, remains to be a prime source of pharmaco-active compounds due to their unique chemical structural scaffolds and functionalities with distinct chemical characteristic feature from natural source that are much acquiescent to drug metabolism and kinetics. In the Post-COVID-Era number of publications pertaining to PBNPs and publicly accessible plant based natural product databases (PBNPDBs) has significantly increased. Moreover, PBNPs are important sources of inspiration or starting points to develop novel therapeutic agents. However, a well-structured, in-depth ADME/Tox profile of PBNPs has been limited or lacking for many of such compounds, this hampers the successful exploitation of PBNPs by pharma industries. Absorption, distribution, metabolism, excretion, and toxicity (ADMET) properties play key roles in the discovery/ development of drugs, pesticides, food additives, consumer products, and industrial chemicals. In the present study, ADMET-informatics of Tetradecanoic Acid (Myristic Acid) from ethyl acetate fraction of Moringa oleifera leaves to predict drug metabolism and pharmacokinetics (DMPK) outcomes has been taken up. This work contributes to the deeper understanding of Myristic acid as major source of drug from commonly available medicinal plant - Moringa oleifera with immense therapeutic potential. The data generated herein could be useful for NP based lead generation programs.

Walnut supplementation reverses the scopolamine-induced memory impairment by restoration of cholinergic function via mitigating oxidative stress in rats: A potential therapeutic intervention for age related neurodegenerative disorders

The brain is highly susceptible to the damaging effects of oxidative reactive species. The free radicals which are produced as a consequence of aerobic respiration can cause cumulative oxygen damage which may lead to age-related neurodegeneration. Scopolamine, the anti-muscarinic agent, induces amnesia and oxidative stress similar to that observed in the older age. Studies suggest that antioxidants derived from plant products may provide protection against oxidative stress. Therefore, the present study was designed to investigate the attenuation of scopolamine-induced memory impairment and oxidative stress by walnut supplementation in rats. Rats in test group were administrated with walnut suspension (400 mg/kg/day) for four weeks. Both control and walnut-treated rats were then divided into saline and scopolamine-treated groups. Rats in the scopolamine group were injected with scopolamine (0.5 mg/kg dissolved in saline) five minutes before the start of each memory test. Memory was assessed by elevated plus maze (EPM), Morris water maze (MWM), and novel object recognition task (NOR) followed by estimation of regional acetylcholine levels and acetylcholinesterase activity. In the next phase, brain oxidative status was determined by assaying lipid peroxidation, and measuring superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase (CAT) activities. Results showed that scopolamine-treatment impaired memory function, caused cholinergic dysfunction, and induced oxidative stress in rats compared to that saline-treated controls. These impairments were significantly restored by pre-administration of walnut. This study demonstrates that antioxidant properties of walnut may provide augmented effects on cholinergic function by reducing oxidative stress and thus improving memory performance
