Anti-cancer agents in medicinal chemistry最新文献

This review investigates the outcome of heavy metal contamination on the anti-cancer properties of medicinal plants. Heavy metal pollution is a significant environmental concern globally, often found in soil and water due to industrial activities. Therapeutic plants are recognized because of their therapeutic attributes and their ability to absorbing these contaminants. This study examines how heavy metal exposure modifies the chemical composition and efficacy of medicinal plants against cancer cells. Through a comprehensive review of existing literature and experimental analysis, we explore the mechanisms by which heavy metals interact with bioactive compounds in medicinal plants, affecting their anti-cancer potency. Findings reveal intricate interactions among heavy metals and phytochemicals, leading to variations in cytotoxicity against cancer cells. Comprehending these interactions is crucial for optimizing the utilization of medicinal plants in cancer treatment and for developing approaches to alleviate the impacts of heavy metal contamination on their therapeutic potential. The urgency of this issue cannot be overstated, as it directly impacts our ability to effectively treat cancer and preserve our environment.

Background: Colorectal cancer (CRC) is the second-leading cause of cancer-related deaths. Curcumin has been reported to have suppressive effects in CRC and to address the physiological limitations of curcumin, a chemically synthesized curcuminoid analog, known as (2E,6E)-2,6-Bis (2,3-Dimethoxy benzylidine) cyclohexanone (DMCH), was developed and the anti-metastatic and anti-angiogenic properties of DMCH in colorectal cell line, SW620 were examined.

Methods: The anti-metastatic effects of DMCH were examined in the SW620 cell line by scratch assay, migration, and invasion assay, while for anti-angiogenesis properties of the cells, the mouse aortic ring assay and Human Umbilical Vein Endothelial Cells (HUVEC) assay were conducted. The mechanism of action was determined by microarray-based gene expression and protein analyses.

Results: The wound healing assay demonstrated that wound closure was decreased from 63.63 ± 1.44% at IC25 treatment to 4.54 ± 0.62% at IC50 treatment. Significant (p<0.05) reductions in the percentage of migrated and invaded cells were also observed in SW620, with values of 36.39 ± 3.86% and 44.81 ± 3.54%, respectively. Mouse aortic ring assays demonstrated a significant reduction in the formation of tubes and microvessels. Microarray and protein profiler results revealed that DMCH treatment has modulated several metastases, angiogenesisrelated transcripts, and proteins like Epidermal Growth Factor Receptor (EGFR), TIMP-1 (TIMP Metallopeptidase Inhibitor 1) and Vascular Endothelial Growth Factor (VEGF).

Conclusion: DMCH could be a potential anti-cancer agent due to its capability to impede metastasis and angiogenesis activities of the SW620 colorectal cancer cell line in vitro via regulating genes and protein in metastases and angiogenesis-related signalling pathways.

Nitrogen-based organic heterocyclic compounds are an important source of therapeutic agents. About 75% of drugs approved by the FDA and currently available in the market are N-heterocyclic organic compounds. The N-heterocyclic organic compounds like pyridine, indole, triazoles, triazine, imidazoles, benzimidazoles, quinazolines, pyrazoles, quinolines, pyrimidines, porphyrin, etc. have demonstrated significant biological activities. These heterocyclic organic compounds also coordinate with various metal ions and form coordination compounds. Most of them have shown improved biological activities. The research on the metal complexes of these compounds reported their significant biological activities. N-heterocyclic-based metal complexes showed outstanding anticancer activities against different cancer cell lines, including VEGFR-2, HT-29, MDA-MB-231, MCF-7 K562, A549, HepG2, HL60, A2780, WI-38, Colo-205, PC-3, and other cancer cell lines. Some of these compounds showed better anticancer activity than cisplatin. In this review, we summarized the anticancer properties of N-heterocyclic-based gold (Au), silver (Ag), and copper (Cu) complexes and explored the mechanisms of action and potential structure-activity relationships (SAR) of these complexes. Our goal is to assist researchers in designing highly potent N-heterocyclic-based Au, Ag, and Cu complexes for the potential treatment of various cancers.

Long non-coding RNA (lncRNA) is a type of non-coding RNA distinguished by a length exceeding 200 nucleotides. Recent studies indicated that lncRNAs participate in various biological processes, such as chromatin remodeling, transcriptional and post-transcriptional regulation, and the modulation of cell proliferation, death, and differentiation, hence influencing gene expression and cellular function. ADAMTS9-AS1, an antisense long non-coding RNA situated on human chromosome 3p14.1, has garnered significant interest due to its pivotal involvement in the advancement and spread of diverse malignant tumors. ADAMTS9-AS1 functions as a competitive endogenous RNA (ceRNA) that interacts with multiple microRNAs (miRNAs) and plays a crucial role in regulating gene expression and cellular functions by modulating essential signaling pathways, including PI3K/AKT/mTOR, Wnt/β-catenin, and Ras/MAPK pathways. Dysregulation of this factor has been linked to tumor development, migration, invasion, and resistance to apoptotic mechanisms, including as iron-induced apoptosis, underscoring its intricate function in cancer pathology. While current research has clarified certain pathways involved in cancer formation, additional clinical and in vivo investigations are necessary to enhance comprehension of its specific involvement across various cancer types. This review encapsulates the recent discoveries on the correlation of ADAMTS9-AS1 with numerous malignancies, clarifying its molecular mechanisms and its prospective role as a therapeutic target in oncology. Furthermore, it identifies ADAMTS9-AS1 as a potential early diagnostic biomarker and therapeutic target, offering novel opportunities for targeted intervention in oncology.

Oral cancer, currently ranked 16th among the most prevalent malignancies worldwide according to GLOBOCAN, presents significant challenges to global oral health. Conventional treatment modalities such as surgery, radiation, and chemotherapy often have limitations, prompting the need for innovative therapeutic approaches. Tissue engineering has emerged as a promising solution aimed at developing biocompatible, functional, and biologically responsive tissue constructs. This approach involves the integration of cells, bioactive compounds, and scaffolds to enhance treatment efficacy. Electrospun nanofibers, mimicking the extracellular matrix, exhibit considerable potential in addressing complex oral health issues by influencing cellular behavior. The versatility of electrospinning technology allows for the fabrication of fiber scaffolds with high surface area, making them ideal for localized delivery of bioactive compounds or pharmaceuticals. Enhancing these electrospun scaffolds with growth factors, nanoparticles, and biologically active substances significantly increases their therapeutic appeal in oral cancer management. This review offers a comprehensive examination of the various applications of electrospun nanofibers in oral cancer therapy. Utilizing electronic databases such as PubMed, CrossREF, and Google Scholar, we conducted an extensive review of relevant literature concerning "electrospun nanofibers" and their therapeutic potential in oral cancer treatment. Key topics addressed include engineering methodologies, drug diffusion mechanisms, factors influencing nanofiber scaffold design, toxicity concerns, and clinical implications. The findings underscore the transformative potential of electrospun nanofibers in revolutionizing oral cancer therapy.

The alternative splicing (AS) of pre-mRNA is an important process in controlling the expression of human genes, which can enrich the diversity of the proteome and regulate gene function. On the contrary, aberrant splicing contributes significantly to numerous human diseases progression, including tumors, neurological diseases, metabolic diseases, infections, and immune diseases. The PUF60, a protein related to RNA splicing, plays critical functions in RNA splicing and gene transcription regulation. In addition, it can achieve synergistic binding with U2AF65 on RNA through interactions in the pyrimidine region, promoting the splicing of introns with weak 3'- splice sites and pyrimidine bundles. Nevertheless, an increasing amount of evidence supports that it shows a significant overexpression pattern in the vast majority of cancer cells and is crucial for embryonic development, indicating that PUF60 may hold the post of a potential therapeutic target for such diseases. These studies have significantly increased our interest in PUF60. Thus, we briefly reviewed the structural domain characteristics of the PUF60, splicing mutants of PUF60, and the roles and functions in human diseases, including various cancers, infections of bacterium and viruses, myositis, and Verheij syndrome. Furthermore, the targeted PUF60 inhibitors and boundedness of the current research were elaborated on in the article. The article effectively communicates critical perception and insight, making it a precious resource for those interested in PUF60 research and treatment.

In women globally, breast cancer ranks as the second most frequent cause of cancer-related deaths, making up about 25% of female cancer cases, which is pretty standard in affluent countries. Breast cancer is divided into subtypes based on aggressive, genetic and stage. The precise cause of the problem is still unknown. However, the following significant risk factors have been found: sex, age, heredity, not having children, breastfeeding, elevated hormone levels, and personal lifestyle. The presence or lack of three nuclear receptors ER, PR, and HER2/ERBB2 (triple negative) and the amplification of the HER2/ErbB2 gene are the clinical criteria used to classify breast cancer. Chemotherapy is still the cornerstone of treatment for triple-negative breast cancer (TNBC), even. If, for the first two groups of patients,receptor-specific therapy is used. The most often prescribed chemotherapy agents for the treatment of breast cancer include doxorubicin (DOX), curcumin paclitaxel (PTX), docetaxel (DCX), thioridazine (THZ), disulfiram (DSF), and camptothecin (CPT). Monoclonal antibodies (mAbs) were used in antibody-drug conjugates (ADCs) to bind tumor-associated target antigens selectively and deliver very effective cytotoxic agents. According to recent research, synthetic derivatives effectively combat both MCF- 7 and breast cancer cell lines that are resistant to many drugs. This review provides a wealth of information on the mechanism of action of synthetic derivatives on multidrug-resistant cell lines. This review includes information about how synthetic derivatives affect cancer cells that have developed multidrug resistance during chemotherapy. These mechanisms have been linked to factors such as increased drug efflux, genetic factors, growth factors, increased DNA repair capacity, and elevated xenobiotic metabolism. Because of this, more research is necessary to learn more about the effectiveness of synthetic derivatives against breast cancer and cell lines that are resistant to several drugs. This review aims to find recent prospects of various types of cellular signaling pathways (JAK/STAT, Akt, MAPK, etc.) involved in the progression of breast cancer disorder, and we also study different synthetic and natural drugs that are applied for treating breast cancer.

Lung cancer is correlated with a high death rate, with approximately 1.8 million mortality cases reported worldwide in 2022. Despite development in the control of lung cancer, most cases are detected at higher stages with short survival rates. This reveals a need to recognize novel techniques to treat malignancy and decrease the burden of lung cancer. Long noncoding RNAs (lncRNAs) manage vital cellular and biochemical functions. lncRNAs play crucial roles in transcriptional and translational processes and signaling cascades. Recently, lncRNAs have been reported to be associated with malignancy where their expression is deregulated, leading to abnormal cellular activities and signaling pathways. In various malignancies, including lung cancer, lncRNA deregulation disrupts normal cellular function, promoting tumorigenesis and influencing patient outcomes and treatment responses. Studies have shown that lncRNAs can act as both oncogenes and tumor suppressors, depending on the lung cancer subtype, specifically in Non-small Cell Lung Cancer (NSCLC) and Small Cell Lung Cancer (SCLC). This dual role of lncRNAs as critical biomarkers might provide insights into lung cancer development and progression. lncRNAs have been discussed as key biomarkers in lung cancer. A comprehensive understanding of the biological activities of lncRNAs in NSCLC and SCLC may improve prognosis, diagnosis, and therapeutic methods. Researchers are increasingly interested in lncRNAs as potential diagnostic biomarkers and therapeutic targets in cancer treatment. As researchers continue to explore lncRNAs, their pivotal roles in lung cancer become increasingly evident. This review highlights the function of lncRNAs in lung carcinogenesis and discusses their molecular mechanisms of function.
