Special Issue Information

Dear Colleagues,

We warmly welcome you to contribute to our Special Issue. This issue delves into targeting cancer and metabolic diseases with bioactive compounds derived from medicinal plants, advocating for tumor and metabolic disorders, including diabetes, dyslipidemia, obesity, MAFLD, and others, as well as prevention and intervention using these naturally derived remedies. Cancer is a complex and pervasive disease, representing a global health challenge. The disease characterizes the abnormal and uncontrolled proliferation of cells. Often, cancer invades surrounding tissues and metastasizes distant organs. Since cancer is heterogenous and adaptable, there remains a threat due to the limitations of conventional therapies, including drug resistance, severe side effects, and variability in efficacy across different cancer types and individual patterns, resulting in the need for novel therapeutic agents to more precisely target cancer cells or enhance the effectiveness of existing treatments, ultimately minimizing adverse events. On the other hand, metabolic diseases are non-communicable disorders that predispose individuals to an increased mortality rate. Metabolic diseases are also heterogeneous and depend on several factors, such as dietary patterns. In these scenarios, bioactive compounds from medicinal plants emerge as a candidate strategy. They are more cost-effective, present minimal side effects, possess many anticancer activities, and are primarily anti-inflammatory, antioxidant, antidiabetic, hepatoprotective, and antigenotoxic. In addition, they have been used since ancient times, and their effectiveness against the diseases of today’s world must be widely tested. Therefore, this Special Issue aims to publish high-quality research and review articles to elucidate bioactive compounds' anticancer and metabolic-enhancing potential from medicinal plants, advocating for translational research addressing cancer and metabolic disorders prevention and intervention. Synergistic studies between plant compounds and synthetic chemotherapeutic drugs are also welcome regarding cancer therapy. Studies on phytochemicals' antioxidant and anti-inflammatory effects against cancerous cell lineages can also be submitted.

We appreciate your interest in our Special Issue and look forward to receiving your papers. Your contributions will make this project a success!

Background/Objectives: This study investigates the phytochemical composition and anticancer activity of Melaleuca quinquenervia leaf essential oil (MQLEO) from Egypt. Methods: Chemical profiling was performed using GC/MS. Anticancer activity was assessed through cytotoxicity screening against multiple cancer cell lines, with a subsequent evaluation of cell migration, apoptosis, and cell cycle analysis on the most sensitive line (A549). Network pharmacology and molecular docking analyses were employed to identify potential molecular targets and pathways. Results: GC/MS analysis revealed a unique profile dominated by 1,8-cineole (31.57%), α-pinene isomers (both 1R and 1S forms, collectively 21.26%), and sesquiterpene alcohols (viridiflorol: 13.65%; ledol: 4.55%). These results diverge from prior studies, showing a 25.63% decrease in 1,8-cineole and no detectable α-terpineol, suggesting environmental, genetic, or methodological impacts on biosynthesis. In vitro tests revealed selective cytotoxicity against A549 lung cancer cells (IC50 = 18.09 μg/mL; selectivity index = 4.30), meeting NCI criteria. Staurosporine was used as a positive control to validate the assays, confirming the reliability of the methods. MQLEO also inhibited cell migration (62–68% wound closure reduction) and induced apoptosis (24.32% vs. 0.7% in controls). Cell cycle arrest at the G0-G1 phase implicated cyclin-dependent kinase regulation. Network pharmacology identified ESR1, CASP3, PPARG, and PTGS2 as key targets, with MQLEO components engaging apoptosis, inflammation (TNF, IL-17), and estrogen pathways. Conclusions: MQLEO demonstrates promising anticancer activity through multiple mechanisms including apoptosis induction, cell cycle arrest, and migration inhibition. The multi-target activity profile highlights its potential as a therapeutic candidate for lung cancer, warranting further in vivo validation and pharmacokinetic studies to advance clinical translation.

Background/Objectives: Astaxanthin, a xanthophyll carotenoid, has garnered significant interest due to its benefits with regard to dyslipidemia. This multifaceted functional food ingredient modulates several key enzymes associated with lipid regulation, including HMG-CoA reductase, CPT1, ACCβ, and acyl-CoA oxidase. It influences key antioxidant molecular pathways like the Nrf2, limiting dyslipidemia occurrence and regulating liver cholesterol uptake through the modulation of liver lipid receptors. Due to the current lack of systematic reviews and meta-analyses assessing moderate to high dosages (6–24 mg/d) of astaxanthin supplementation on lipid dysregulation, the present manuscript aims to fill this gap in the literature. Methods: Following the PRISMA guidelines, we included eight studies comprising eleven results from the PubMed, Springer Link, Science Direct, Cochrane, and Google Scholar databases. The Jamovi (Version 2.6.26, Solid) software was utilized for statistics. Our primary objective was to assess in detail the effects of astaxanthin on LDL-C, HDL-C, triglyceride, and total cholesterol levels. Results: The meta-analysis concludes positive effects of astaxanthin (6–20 mg/d) on HDL-C (0.4200; 95% CI: 0.1081 to 0.7319) and triglyceride (−0.3058; 95% CI: −0.5138 to −0.0978) levels. Unfortunately, astaxanthin (6–20 mg/d) does not appear to significantly influence LDL-C (−0.0725; 95% CI: −0.3070 to 0.1620) and total cholesterol (−0.0448; 95% CI: −0.3369 to 0.2473) levels. Regarding HDL-C, improvements were observed from 55 ± 8 mg/dL (pre-intervention) to 63 ± 8 mg/dL (post-intervention) (p < 0.01) in the 12 mg/d of astaxanthin groups. In the assessment of triglyceride levels, results show a decrease from 151 ± 26 mg/dL (pre-intervention) to 112 ± 40 mg/dL (post-intervention) (p < 0.01) for 18 mg/d astaxanthin supplementation. Conclusions: Further research is necessary to fully harness the potential of astaxanthin, which includes assessing astaxanthin in different subsets of patients, using a GWAS, and in combination with other nutraceuticals to understand the compound’s effectiveness with regard to varying health conditions, genetic and epigenetic factors, and synergistic effects with other compounds.
