Role of diosmin in preventing doxorubicin-induced cardiac oxidative stress, inflammation, and hypertrophy: A mechanistic approach. Saudi Pharm J 2024; 32:102103. [PMID: 38799001 PMCID: PMC11127263 DOI: 10.1016/j.jsps.2024.102103] [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: 03/25/2024] [Accepted: 05/14/2024] [Indexed: 05/29/2024] Open
Abstract
Chemotherapeutic drugs, such as doxorubicin (Dox), are commonly used to treat a variety of malignancies. However, Dox-induced cardiotoxicity limits the drug's clinical applications. Hence, this study intended to investigate whether diosmin could prevent or limit Dox-induced cardiotoxicity in an animal setting. Thirty-two rats were separated into four distinct groups of controls, those treated with Dox (20 mg/kg, intraperitoneal, i.p.), those treated with diosmin 100 mg plus Dox, and those treated with diosmin 200 mg plus Dox. At the end of the experiment, rats were anesthetized and sacrificed and their blood and hearts were collected. Cardiac toxicity markers were analyzed in the blood, and the heart tissue was analyzed by the biochemical assays MDA, GSH, and CAT, western blot analysis (NF-kB, IL-6, TLR-4, TNF-α, iNOS, and COX-2), and gene expression analysis (β-MHC, BNP). Formalin-fixed tissue was used for histopathological studies. We demonstrated that a Dox insult resulted in increased oxidative stress, inflammation, and hypertrophy as shown by increased MDA levels and reduced GSH content and CAT activity. Furthermore, Dox treatment induced cardiac hypertrophy and damage, as evidenced by the biochemical analysis, ELISA, western blot analysis, and gene expression analysis. However, co-administration of diosmin at both doses, 100 mg and 200 mg, mitigated these alterations. Data derived from the current research revealed that the cardioprotective effect of diosmin was likely due to its ability to mitigate oxidative stress and inflammation. However, further study is required to investigate the protective effects of diosmin against Dox-induced cardiotoxicity.

Ullah A, Rehman NU, Islam WU, Khan F, Waqas M, Halim SA, Jan A, Muhsinah AB, Khan A, Al-Harrasi A. Identification of small molecular inhibitors of SIRT3 by computational and biochemical approaches a potential target of breast cancer. Sci Rep 2024; 14:12475. [PMID: 38816444 PMCID: PMC11139978 DOI: 10.1038/s41598-024-63177-7] [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: 09/20/2023] [Accepted: 05/27/2024] [Indexed: 06/01/2024] Open
Abstract
Sirtuin 3 (SIRT3) belongs to the Sirtuin protein family, which consists of NAD+-dependent lysine deacylase, involved in the regulation of various cellular activities. Dysregulation of SIRT3 activity has been linked to several types of cancer, including breast cancer. Because of its ability to stimulate adaptive metabolic pathways, it can aid in the survival and proliferation of breast cancer cells. Finding new chemical compounds targeted towards SIRT3 was the primary goal of the current investigation. Virtual screening of ~ 800 compounds using molecular docking techniques yielded 8 active hits with favorable binding affinities and poses. Docking studies verified that the final eight compounds formed stable contacts with the catalytic domain of SIRT3. Those compounds have good pharmacokinetic/dynamic properties and gastrointestinal absorption. Based on excellent pharmacokinetic and pharmacodynamic properties, two compounds (MI-44 and MI-217) were subjected to MD simulation. Upon drug interaction, molecular dynamics simulations demonstrate mild alterations in the structure of proteins and stability. Binding free energy calculations revealed that compounds MI-44 (- 45.61 ± 0.064 kcal/mol) and MI-217 (- 41.65 ± 0.089 kcal/mol) showed the maximum energy, suggesting an intense preference for the SIRT3 catalytic site for attachment. The in-vitro MTT assay on breast cancer cell line (MDA-MB-231) and an apoptotic assay for these potential compounds (MI-44/MI-217) was also performed, with flow cytometry to determine the compound's ability to cause apoptosis in breast cancer cells. The percentage of apoptotic cells (including early and late apoptotic cells) increased from 1.94% in control to 79.37% for MI-44 and 85.37% for MI-217 at 15 μM. Apoptotic cell death was effectively induced by these two compounds in a flow cytometry assay indicating them as a good inhibitor of human SIRT3. Based on our findings, MI-44 and MI-217 merit additional investigation as possible breast cancer therapeutics.

Int J Mol Sci 2024; 25:1755.

Abstract
This article provides a thorough overview of the biomarkers, pathophysiology, and molecular pathways involved in the transition from acute kidney injury (AKI) and acute kidney disease (AKD) to chronic kidney disease (CKD). It categorizes the biomarkers of AKI into stress, damage, and functional markers, highlighting their importance in early detection, prognosis, and clinical applications. This review also highlights the links between renal injury and the pathophysiological mechanisms underlying AKI and AKD, including renal hypoperfusion, sepsis, nephrotoxicity, and immune responses. In addition, various molecules play pivotal roles in inflammation and hypoxia, triggering maladaptive repair, mitochondrial dysfunction, immune system reactions, and the cellular senescence of renal cells. Key signaling pathways, such as Wnt/β-catenin, TGF-β/SMAD, and Hippo/YAP/TAZ, promote fibrosis and impact renal function. The renin-angiotensin-aldosterone system (RAAS) triggers a cascade leading to renal fibrosis, with aldosterone exacerbating the oxidative stress and cellular changes that promote fibrosis. The clinical evidence suggests that RAS inhibitors may protect against CKD progression, especially post-AKI, though more extensive trials are needed to confirm their full impact.
