RESUMO

Vascular dementia (VaD) accounts to 30% of cases and is predicted as second most common form of dementia after Alzheimer's disease by WHO. Earlier studies reported that plant-derived pentacyclic triterpenoids possess a wide range of pharmacological activities but these compounds are not extensively studied for their neuroprotective potential against VaD. This in silico approach was designed to screen 20 pentacyclic triterpenoid plant compounds against known targets of VaD using Flare software. S-Adenyl homocysteine hydrolase, Acetylcholinesterase, and Butyrylcholinesterase were selected as important VaD targets, and various parameters like intermolecular interaction energies, binding energy, and dock scores were analyzed and compared between selected ligands. Our results showed that Ursolic acid has lowest binding energy when docked with most of the target proteins, and among all 20 pentacyclic triterpenoids studied, only three ligands Betulinic acid, Ambolic acid, and Madecassic acid, showed better binding energy scores, and they can be shortlisted as lead compounds to further study their therapeutic potential against VaD using in vitro and in vivo animal models.

RESUMO

Neurodegenerative disorders pose a significant health burden and imprint a debilitative impact on the quality of life. Importantly, aging is intricately intertwined with the progression of these disorders, and their prevalence increases with a rise in the aging population worldwide. In recent times, fisetin emerged as one of the potential miracle molecules to address neurobehavioral and cognitive abnormalities. These effects were attributed to its actions on several macromolecules and multiple molecular mechanisms. Fisetin belongs to a class of flavonoids, which is found abundantly in several fruits and vegetables. Fisetin has manifested several health benefits in preclinical models of neurodegenerative diseases such as Alzheimer's disease, Vascular dementia, and Schizophrenia. Parkinson's disease, Amyotrophic Lateral Sclerosis, Huntington's disease, Stroke, Traumatic Brain Injury (TBI), and age-associated changes. This review aimed to evaluate the potential mechanisms and pharmacological effects of fisetin in treating several neurological diseases. This review also provides comprehensive data on up-to-date recent literature and highlights the various mechanistic pathways pertaining to fisetin's neuroprotective role.

RESUMO

Diabetes mellitus is one of the threatening, non-communicable and chronic ailments worldwide since ancient times to the current stage of human existence. The utilization of nanoparticles as a medicine in the treatment of diabetes is an attractive proposition. In the present study, herbal mediated cerium oxide nanoparticles (HMCeO2 NPs), herbal mediated silver nanoparticles (HMAg NPs) and Lawsonia intermix extract (LIE) was evaluated for them for in-vivo hypoglycemic effect and compared the potency. The resulting HMCeO2 NPs, HMAg NPs and Lawsonia inermis have been characterized by different analytical equipments such as X-ray Diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Particle size analyzer (PSA), Field emission scanning electron microscope (FESEM) and High resolution transmission electron microscope (HRTEM). The synthesized NPs and Lawsonia inermis extract were assessed for toxicity by using acute oral toxicity using female albino mice (s) model by following OECD-425 guidelines. In in-vivo hypoglycemic animal model, the male wistar rats with weight varying between 180-200 gms were grouped as: normal control: did not receive any treatment, diabetic control (saline): received a single intraperitoneal dose of Streptozotocin (40 mg/kg), standard: received a single daily oral dose of 50 mg/kg body weight, HMCeO2 NPs: received single daily oral dose of 100 mg/kg, 200 mg/kg, HMAg NPs: received a single daily oral dose of 100 mg/kg, 200 mg/kg, and Lawsonia inermis: received a single daily oral dose of 100 mg/kg, 200 mg/kg. The herbal mediated NPs were considered safe as they have not shown toxic effects. From the current study results, it may conclude that, due to the advanced biological and pharmacological characters, the HMAg NPs depicted more potent hypoglycemic activity than that of LIE and CeO2 NPs.
