Biochemical features and therapeutic potential of α-Mangostin: Mechanism of action, medicinal values, and health benefits. Biomed Pharmacother 2023; 163:114710. [PMID: 37141737 DOI: 10.1016/j.biopha.2023.114710] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Revised: 04/12/2023] [Accepted: 04/12/2023] [Indexed: 05/06/2023] Open
Abstract
α-Mangostin (α-MG) is a natural xanthone obtained from the pericarps of mangosteen. It exhibits excellent potential, including anti-cancer, neuroprotective, antimicrobial, antioxidant, and anti-inflammatory properties, and induces apoptosis. α-MG controls cell proliferation by modulating signaling molecules, thus implicated in cancer therapy. It possesses incredible pharmacological features and modulates crucial cellular and molecular factors. Due to its lesser water solubility and pitiable target selectivity, α-MG has limited clinical application. As a known antioxidant, α-MG has gained significant attention from the scientific community, increasing interest in extensive technical and biomedical applications. Nanoparticle-based drug delivery systems were designed to improve the pharmacological features and efficiency of α-MG. This review is focused on recent developments on the therapeutic potential of α-MG in managing cancer and neurological diseases, with a special focus on its mechanism of action. In addition, we highlighted biochemical and pharmacological features, metabolism, functions, anti-inflammatory, antioxidant effects and pre-clinical applications of α-MG.

Abstract
Tank-binding kinase 1 (TBK1) is a multifunctional kinase having essential roles in cellular processes, autophagy/mitophagy, and selective clearance of damaged proteins. More than 90 mutations in the TBK1 gene are linked with multiple cancer types, amyotrophic lateral sclerosis (ALS), and frontotemporal dementia (FTD). Some of these missense mutations disrupt the abilities of TBK1 to dimerize, associate with the mitophagy receptor optineurin (OPTN), autoactivate, or catalyze phosphorylation. Some mutations may cause severe dysregulation of the pathway, while others induce a limited disruption. Here, we have studied those mutations reported in cancer, ALS and FTD, and subsequently investigated the effect of missense mutations on the structure and function of TBK1 for localized residual frustration change. Out of 33 ALS/FTD causing mutations and 28 oncogenic mutations, 10 mutations and 12 oncogenic mutations showed significant change in the residual frustration. The local frustration plays an important role in the conformation of protein structure in active and inactive kinases. Our analysis reports the change in residual frustration state, conformational change and effect on active and inactive TBK1 function due to ALS/FTD causing and oncogenic missense mutations.

Abstract
Iron deposition in the central nervous system (CNS) is one of the causes of neurodegenerative diseases. Human transferrin (hTf) acts as an iron carrier present in the blood plasma, preventing it from contributing to redox reactions. Plant compounds and their derivatives are frequently being used in preventing or delaying Alzheimer's disease (AD). Thymoquinone (TQ), a natural product has gained popularity because of its broad therapeutic applications. TQ is one of the significant phytoconstituent of Nigella sativa. The binding of TQ to hTf was determined by spectroscopic methods and isothermal titration calorimetry. We have observed that TQ strongly binds to hTf with a binding constant (K) of 0.22 × 106 M-1 and forming a stable complex. In addition, isothermal titration calorimetry revealed the spontaneous binding of TQ with hTf. Molecular docking analysis showed key residues of the hTf that were involved in the binding to TQ. We further performed a 250 ns molecular dynamics simulation which deciphered the dynamics and stability of the hTf-TQ complex. Structure analysis suggested that the binding of TQ doesn't cause any significant alterations in the hTf structure during the course of simulation and a stable complex is formed. Altogether, we have elucidated the mechanism of binding of TQ with hTf, which can be further implicated in the development of a novel strategy for AD therapy.

Targeted protein degraders march towards the clinic for neurodegenerative diseases. Ageing Res Rev 2022; 78:101616.

Abstract
Protein degraders are emerging as potent therapeutic tools to address neurological disorders and many complex diseases. It offered several key advantages, including the doses, drug resistance, and side effects over traditional occupancy-based inhibitors. Translation of chemical degraders into a clinical therapy for neurodegenerative disorders has a well-documented knowledge and resource gap. Researchers strive to develop clinical candidates employing chemical degraders' technologies, including hydrophobic tagging, molecular glues, proteolysis targeting chimeras (PROTACs), specific and nongenetic Inhibitor of Apoptosis Protein (IAP)-dependent protein erasers (SNIPERs), autophagy targeted chimeras, and autophagosome-tethered compounds for targeted degradation of pathological markers in neurodegenerative disease. Herein, we examined the present state of chemical-mediated targeted protein degradation in the quest for medications to treat neurodegenerative diseases. We further identified targeted degraders under clinical development for neurodegenerative diseases summarizing pertinent discoveries guiding the future of degradation therapeutics. We also addressed the necessary pharmacological interventions needed to achieve unprecedented therapeutic efficacy and its associated challenges.

Structural genomics approach to investigate deleterious impact of nsSNPs in conserved telomere maintenance component 1. Sci Rep 2021; 11:10202. [PMID: 33986331 PMCID: PMC8119478 DOI: 10.1038/s41598-021-89450-7] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2021] [Accepted: 04/14/2021] [Indexed: 02/07/2023] Open
Abstract
Conserved telomere maintenance component 1 (CTC1) is an important component of the CST (CTC1-STN1-TEN1) complex, involved in maintaining the stability of telomeric DNA. Several non-synonymous single-nucleotide polymorphisms (nsSNPs) in CTC1 have been reported to cause Coats plus syndrome and Dyskeratosis congenital diseases. Here, we have performed sequence and structure analyses of nsSNPs of CTC1 using state-of-the-art computational methods. The structure-based study focuses on the C-terminal OB-fold region of CTC1. There are 11 pathogenic mutations identified, and detailed structural analyses were performed. These mutations cause a significant disruption of noncovalent interactions, which may be a possible reason for CTC1 instability and consequent diseases. To see the impact of such mutations on the protein conformation, all-atom molecular dynamics (MD) simulations of CTC1-wild-type (WT) and two of the selected mutations, R806C and R806L for 200 ns, were carried out. A significant conformational change in the structure of the R806C mutant was observed. This study provides a valuable direction to understand the molecular basis of CTC1 dysfunction in disease progression, including Coats plus syndrome.

Abstract
Neurodegeneration is a prevalent and one of the emerging reasons for morbidity, mortality, and cognitive impairment in aging. Dementia is one of such conditions of neurodegeneration, partially manageable, irreversible, and worsens over time. This review is focused on biological and psychosocial risk factors associated with Alzheimer's and Parkinson's diseases, highlighting the value of cognitive decline. We further emphasized on current therapeutic strategies from pharmacological and non-pharmacological perspectives focusing on their effects on cognitive impairment, protein aggregation, tau pathology, and improving the quality of life. Deeper mechanistic insights into the multifactorial neurodegeneration could offer the design and development of promising diagnostic and therapeutic strategies.
