Heliyon 2024; 10:e32209. [PMID: 38912489 PMCID: PMC11190594 DOI: 10.1016/j.heliyon.2024.e32209] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2024] [Revised: 05/07/2024] [Accepted: 05/29/2024] [Indexed: 06/25/2024] Open
Abstract
Alzheimer's disease (AD) is a brain illness that causes cognitive impairment in the elderly, especially females, as a result of genetics, hormones, and life experiences. It becomes more severe with age and is associated with cardiovascular disease, hypertension, and diabetes. Beta-amyloid plaques and hyper phosphorylated Tau protein buildup are common clinical findings. Misfiling of amyloid precursor protein (APP) and Amyloid beta peptide (Aβ) proteins contributes to Alzheimer's disease. Enzyme Acetylcholinesterase enzyme interacts with amyloid-beta, enhancing its accumulation in insoluble plaques, leading to successful treatment for Alzheimer's disease primarily based on lowering this enzyme. Treatments include using the Rivastigmine for mild, moderate, or severe Alzheimer's disease, which inhibits acetylcholinesterase, but may cause side effects; Solanine derivatives, nightshade toxin, it is cholinesterase inhibitory, may mitigate Alzheimer's illness is progressing. In this research utilized a molecular docking program, which is a computer's computational ability to determine the optimal position for a specific compound to bind to a protein or target, forming a target-ligand complex and displaying biological activity and aiding in the development of effective anti-AD treatments and understanding AD pathological mechanisms. The study examined complexes of 3LII (Acetylcholinesterase receptor) in the A and B chain with Solanine and Rivastigmine derivatives, using an in-silico approach. PyRx default sorter was used to improve docking accuracy. Four compounds were selected based on their higher binding affinities in chain A and B. The results showed that Solanine derivatives (alpha-Solanine, Beta1-Solanine and Beta2-Solanine) have higher binding strength (-9.0,-9.3 and -8.6) than Rivastigmine (-7.2) in chain A, and also the binding strength was high for the Solanine derivatives (alpha-Solanine, Beta1-Solanine, and Beta2-Solanine) (-9.0,-8.8 and -8.9) is higher than Rivastigmine (-6.0) in the chain B. Solanine derivatives showed higher binding strength with acetylcholinesterase, potentially for to reduce the progression of the disease.

Sharma A, Ray A, Sathaye S, Singhal RS. A supercritical fluid co-extract of turmeric powder and dried coconut shreds shows neuroprotection against AlCl 3-induced Alzheimer's disease in rats through nose to brain delivery. Bioorg Chem 2024; 143:107046. [PMID: 38141332 DOI: 10.1016/j.bioorg.2023.107046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 12/06/2023] [Accepted: 12/16/2023] [Indexed: 12/25/2023]
Abstract
This study was aimed at investigating the neuroprotective potential of a co-extract obtained by supercritical fluid extraction (SFE) of turmeric powder and dried coconut shreds against aluminium chloride (AlCl3)-induced Alzheimer's disease (AD) in male Wistar rats. Fifty animals were allocated to five groups, which received saline (vehicle control, group 1), a combination of saline and aluminium chloride (AlCl3) (disease control, group 2), coconut oil (COO) (SFE extracted, treatment group 3), turmeric oleoresin (Cur) (SFE extracted, treatment group 4) and SFE co-extract of turmeric powder and coconut shreds (CurCOO) (treatment group 5). Animals were subjected to behavioural evaluation. In addition, the hippocampal section of the brain from all groups was subjected to biochemical, molecular and histopathological evaluations. The results showed CurCOO administered intranasally improved cognitive abilities, reversed histological alterations in the brain, reduced hippocampus inflammation studied through proinflammatory cytokine markers like TNF-α and IL-6 as compared to the disease control group. The impact of CurCOO on preventive neurodegeneration was also observed through a reduction in protein transcription factor NF-kB in the treated group 5 as compared to a disease control group. The effect of intranasal delivery of CurCOO on the neurons responsible for memory consolidation was evident from low acetylcholinesterase (AChE) enzyme activity in the treated groups with respect to AlCl3 induced group. Summarily, the results demonstrated intranasal delivery of CurCOO to show better efficacy than Cur and COO in preventing neurodegeneration associated with AlCl3 induced Alzheimer's disease.

Curcuminoids-enriched extract and its cyclodextrin inclusion complexes ameliorates arthritis in complete Freund's adjuvant-induced arthritic mice via modulation of inflammatory biomarkers and suppression of oxidative stress markers. Inflammopharmacology 2023; 31:3047-3062.

Abstract
Curcuma longa extract and its marker curcuminoids have potential use in inflammatory conditions. However, curcuminoids solubility and bioavailability are major hindrances to their bioactivity. The current study investigated green extraction-based curcuminoids-enriched extract (CRE) prepared from C. longa and its cyclodextrin inclusion complexes, i.e., binary inclusion complexes (BC) and ternary inclusion complexes (TC), in complete Freund's adjuvant (CFA)-induced mice for their comparative anti-arthritic efficacy. CRE, BC, and TC (2.5 and 5 mg/kg) with the standard drug diclofenac sodium (13.5 mg/kg) were orally administered to mice for 4 weeks. Variations in body weight, hematological and biochemical parameters, along with gene expression analysis of arthritis biomarkers, were studied in animals. The histopathological analysis and radiographic examination of joints were also performed. CRE, BC and TC treatment significantly restored the arthritic index, histopathology and body weight changes. The concentration of C-reactive protein, rheumatoid factor and other liver function parameters were significantly recovered by curcuminoids formulations. The pro-inflammatory cytokines (NF-κB, COX-2, IL-6, IL-1β, and TNF-α) gene expression was considerably (p < 0.001) downregulated, while on the other side, the anti-inflammatory genes IL-4 and IL-10 were upregulated by the use of CRE and its complexes. The concentration of antioxidant enzymes was considerably (P < 0.001) recovered by CRE, BC and TC with marked decrease in lipid peroxidation, erosion of bone, inflammation of joints and pannus formation in comparison to arthritic control animals. Therefore, it is concluded that green CRE and its cyclodextrin formulations with enhanced solubility could be considered as an applicable therapeutic choice to treat chronic polyarthritis.
