Honokiol hexafluoro confers reversal of neuropathological markers of HIV infection in a murine SCID model. Neurotherapeutics 2024; 21:e00329. [PMID: 38388224 PMCID: PMC10943487 DOI: 10.1016/j.neurot.2024.e00329] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2023] [Revised: 01/27/2024] [Accepted: 01/28/2024] [Indexed: 02/24/2024] Open
Abstract
Cognitive impairment remains a persistent challenge in people living with HIV (PWLH) despite antiretroviral therapy (ART) due to ART's inability to eliminate brain HIV. HIV-induced cognitive dysfunction results from immune dysregulation, ongoing neuroinflammation, and the continuous virus presence, collectively contributing to cognitive deficits. Therefore, adjunctive therapies are needed to reduce cerebral HIV reservoirs, mitigate neuroinflammation, and impede cognitive dysfunction progression. Our study focused on Honokiol, known for its anti-inflammatory and neuroprotective properties, in an experimental mouse model simulating HIV-induced cognitive dysfunction. Using Honokiol Hexafluoro (HH), a synthetic analogue, we comprehensively evaluated its potential to ameliorate cognitive dysfunction and cerebral pathology in HIV-associated cognitive dysfunction. Our findings showed that HH treatment effectively reversed HIV-induced cognitive dysfunction, concurrently suppressing astrocyte activation, restoring neuronal dendritic arborization, and reducing microglial activation. Furthermore, HH remodeled the metabolic profile of HIV-infected human monocyte-derived macrophages, resulting in decreased activation and the promotion of a quiescent state in vitro.

Abstract
Lung cancer is one of the most common cancer types of cancer with the highest mortality rates. However, while epidermal growth factor receptor (EGFR) is an important parameter for lung cancer, EGFR inhibitors also show great promise in the treatment of the disease. Therefore, a series of new EGFR inhibitor candidates containing thiadiazole and pyrazole rings have been developed. The activities of the synthesized compounds were elucidated by in vitro MTT, (which is chemically 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide), cytotoxicity assay, analysis of mitochondrial membrane potential (MMP) by flow cytometry, and EGFR inhibition experiments. Molecular docking and molecular dynamics simulations were performed as in silico studies. Compounds 6d, 6g, and 6j showed inhibitor activity against the A549 cell line with IC50 = 5.176 ± 0.164; 1.537 ± 0.097; and 8.493 ± 0.667 μM values, respectively. As a result of MMP by flow cytometry, compound 6g showed 80.93% mitochondrial membrane potential. According to the results of the obtained EGFR inhibitory assay, compound 6g shows inhibitory activity on the EGFR enzyme with a value of IC50 = 0.024 ± 0.002 μM.

Abstract
Alzheimer's disease (AD) is a neurological, progressive illness that typically affects the elderly and is clinically distinguished by memory and cognitive decline. Due to a number of factors, including the absence of a radical treatment, an increase in the patient population over time, the high cost of care and treatment, and a significant decline in patients' quality of life, the importance of this disease has increased. These factors have all prompted increased interest among researchers in this field. The chemical structure of the donepezil molecule, the most popular and effective treatment response for AD, served as the basis for the design and synthesis of 42 novel indan-1-one derivatives in this study. Using IR, 1H, and 13C NMR as well as mass spectroscopic techniques, the compounds' structures were identified. Research on the compounds' antioxidant activities, cholinesterase (ChE) enzyme inhibition, monoamine oxidase (MAO) A and B inhibitory activities, β-amyloid plaque inhibition, and cytotoxicity impact was carried out. Inhibition of β-amyloid plaque aggregation; effective inhibition of AChE, BChE, and MAO-B enzymes; and significant antioxidant activity were all demonstrated by compounds D28-D30 and D37-D39. Because of their various actions, it was hypothesized that the related compounds may be useful in treating AD symptoms as well as providing palliative care.
