[PMID: 38701310 PMCID: PMC11062656 DOI: 10.1097/md.0000000000038023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2023] [Accepted: 04/05/2024] [Indexed: 05/05/2024] Open
Abstract
Cancer remains a significant challenge in the field of oncology, with the search for novel and effective treatments ongoing. Calycosin (CA), a phytoestrogen derived from traditional Chinese medicine, has garnered attention as a promising candidate. With its high targeting and low toxicity profile, CA has demonstrated medicinal potential across various diseases, including cancers, inflammation, and cardiovascular disease. Studies have revealed that CA possesses inhibitory effects against a diverse array of cancers. The underlying mechanism of action involves a reduction in tumor cell proliferation, induction of tumor cell apoptosis, and suppression of tumor cell migration and invasion. Furthermore, CA has been shown to enhance the efficacy of certain chemotherapeutic drugs, making it a potential component in treating malignant tumors. Given its high efficacy, low toxicity, and multi-targeting characteristics, CA holds considerable promise as a therapeutic agent for cancer treatment. The objective of this review is to present a synthesis of the current understanding of the antitumor mechanism of CA and its research progress.

[PMID: 37922652 DOI: 10.1016/j.biopha.2023.115811] [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: 09/09/2023] [Revised: 10/21/2023] [Accepted: 10/26/2023] [Indexed: 11/07/2023] Open
Abstract
Currently, cancer is one of the main research topics, due to its high incidence and drug resistance to existing anti-cancer drugs. Formononetin, a natural product with phytoestrogenic properties and diverse biological functions, has attracted the attention of researchers working on anticancer drugs. Formononetin emerges as an intriguing bioactive substance compared to other isoflavones as it exhibits potent chemotherapeutic activity with less toxicity. Formononetin effectively plays a significant role in inhibiting cell proliferation, invasion, and metastatic abilities of cancer cells by targeting major signaling pathways at the junction of interconnected pathways. It also induces apoptosis and cell cycle arrest by modulating mediator proteins. It causes upregulation of key factors such as p-AKT, p38, p21, and p53 and downregulation of NF-κB. Furthermore, formononetin regulates the neoplastic microenvironment by inactivating the ERK1/2 pathway and lamin A/C signaling and has been reported to inactivate JAK/STAT, PKB or AKT, and mitogen-activated protein kinase pathways and to suppress cell migration, invasion, and angiogenesis in human cancer cells. To assist researchers in further exploring formononetin as a potential anticancer therapeutic candidate, this review focuses on both in vitro and in vivo proof of concept studies, patents, and clinical trials pertinent to formononetin's anticancer properties. Overall, this review discusses formononetin from a comprehensive perspective to highlight its potential benefits as an anticancer agent.

Semilicoisoflavone B Induces Apoptosis of Oral Cancer Cells by Inducing ROS Production and Downregulating MAPK and Ras/Raf/MEK Signaling. Int J Mol Sci 2023; 24:4505. [PMID: 36901935 PMCID: PMC10003514 DOI: 10.3390/ijms24054505] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Revised: 01/26/2023] [Accepted: 01/27/2023] [Indexed: 03/02/2023] Open
Abstract
Oral squamous cell carcinoma (OSCC) is the sixth most common type of cancer worldwide. Despite advancement in treatment, advanced-stage OSCC is associated with poor prognosis and high mortality. The present study aimed to investigate the anticancer activities of semilicoisoflavone B (SFB), which is a natural phenolic compound isolated from Glycyrrhiza species. The results revealed that SFB reduces OSCC cell viability by targeting cell cycle and apoptosis. The compound caused cell cycle arrest at the G2/M phase and downregulated the expressions of cell cycle regulators including cyclin A and cyclin-dependent kinase (CDK) 2, 6, and 4. Moreover, SFB induced apoptosis by activating poly-ADP-ribose polymerase (PARP) and caspases 3, 8, and 9. It increased the expressions of pro-apoptotic proteins Bax and Bak, reduced the expressions of anti-apoptotic proteins Bcl-2 and Bcl-xL, and increased the expressions of the death receptor pathway protein Fas cell surface death receptor (FAS), Fas-associated death domain protein (FADD), and TNFR1-associated death domain protein (TRADD). SFB was found to mediate oral cancer cell apoptosis by increasing reactive oxygen species (ROS) production. The treatment of the cells with N-acetyl cysteine (NAC) caused a reduction in pro-apoptotic potential of SFB. Regarding upstream signaling, SFB reduced the phosphorylation of AKT, ERK1/2, p38, and JNK1/2 and suppressed the activation of Ras, Raf, and MEK. The human apoptosis array conducted in the study identified that SFB downregulated survivin expression to induce oral cancer cell apoptosis. Taken together, the study identifies SFB as a potent anticancer agent that might be used clinically to manage human OSCC.

Abstract
Staphylococcus aureus is a common cause of severe infections, and its widespread antibiotic resistance necessitates search for alternative therapies, such as inhibition of virulence. As S. aureus produces multiple individual virulence factors, inhibition of an entire regulatory system might provide better effects than targeting each virulence factor separately. Herein, we describe two novel inhibitors of S. aureus two-component regulatory system ArlRS: 3,4'-dimethoxyflavone and homopterocarpin. Unlike other putative ArlRS inhibitors previously identified, these two compounds were effective and specific. In vitro kinase assays indicated that 3,4'-dimethoxyflavone directly inhibits ArlS autophosphorylation, while homopterocarpin did not exhibit such effect, suggesting that two inhibitors work through distinct mechanisms. Application of the inhibitors to methicillin-resistant S. aureus (MRSA) in vitro blocked ArlRS signaling, inducing an abnormal gene expression pattern that was reflected in changes at the protein level, enhanced sensitivity to oxacillin, and led to the loss of numerous cellular virulence traits, including the ability to clump, adhere to host ligands, and evade innate immunity. The pleiotropic antivirulence effect of inhibiting a single regulatory system resulted in a marked therapeutic potential, demonstrated by the ability of inhibitors to decrease severity of MRSA infection in mice. Altogether, this study demonstrated the feasibility of ArlRS inhibition as anti-S. aureus treatment, and identified new lead compounds for therapeutic development.

Abstract
BACKGROUND Besides the numerous biologic and pharmacologic functions in the human body that act as potent antioxidants, flavonoids (flavones, flavanones, flavonols, flavanols and isoflavones) are noted as cancer preventive or therapeutic agents. METHODS This review summarizes the published data using PubMed, Science Direct, and Scopus. RESULTS In this context, recognition and introduction of the most active cytotoxic flavonoids as promising agents for cancer therapy gives insight for further evaluations. However, there are some critical points that may affect the entering of flavonoids as active cytotoxic phytochemicals in the clinical phase. Issues such as the abundance of active species in nature, the methods of extraction and purification, solubility, pharmacokinetic profile, presence of the chiral moieties, method of synthesis, and structure modification may limit the entry of a selected compound for use in humans. Although plenty of basic evidence exists for cytotoxic/antitumor activity of the versatility of flavonoids for entry into clinical trials, the above-mentioned concerns must be considered. CONCLUSION This review is an effort to introduce cytotoxic natural flavonoids (IC50< 10 µM) that may have the potential to be used against various tumor cells. Also, active constituents, molecular mechanisms, and related clinical trials have been discussed as well as the limitations and challenges of using flavonoids in clinic.

Abstract
Cancer, a complex yet common disease, is caused by uncontrolled cell division and abnormal cell growth due to a variety of gene mutations. Seeking effective treatments for cancer is a major research focus, as the incidence of cancer is on the rise and drug resistance to existing anti-cancer drugs is major concern. Natural products have the potential to yield unique molecules and combinations of substances that may be effective against cancer with relatively low toxicity/better side effect profile compared to standard anticancer therapy. Drug discovery work with natural products has demonstrated that natural compounds display a wide range of biological activities correlating to anticancer effects. In this review, we discuss formononetin (C16H12O4), which originates mainly from red clovers and the Chinese herb Astragalus membranaceus. The compound comes from a class of 7-hydroisoflavones with a substitution of methoxy group at position 4. Formononetin elicits antitumorigenic properties in vitro and in vivo by modulating numerous signaling pathways to induce cell apoptosis (by intrinsic pathway involving Bax, Bcl-2, and caspase-3 proteins) and cell cycle arrest (by regulating mediators like cyclin A, cyclin B1, and cyclin D1), suppress cell proliferation [by signal transducer and activator of transcription (STAT) activation, phosphatidylinositol 3-kinase/protein kinase-B (PI3K/AKT), and mitogen-activated protein kinase (MAPK) signaling pathway], and inhibit cell invasion [by regulating growth factors vascular endothelial growth factor (VEGF) and Fibroblast growth factor 2 (FGF2), and matrix metalloproteinase (MMP)-2 and MMP-9 proteins]. Co-treatment with other chemotherapy drugs such as bortezomib, LY2940002, U0126, sunitinib, epirubicin, doxorubicin, temozolomide, and metformin enhances the anticancer potential of both formononetin and the respective drugs through synergistic effect. Compiling the evidence thus far highlights the potential of formononetin to be a promising candidate for chemoprevention and chemotherapy.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2019; 58:152872. [PMID: 30826527 DOI: 10.1016/j.phymed.2019.152872] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/18/2018] [Revised: 01/01/2019] [Accepted: 02/19/2019] [Indexed: 06/09/2023]
Abstract
BACKGROUND Glycyrrhiza (licorice) species are rich in bioactive secondary metabolites and their roots are used traditionally for the treatment of several diseases. In recent years, secondary metabolites of licorice are gaining popularity, especially due to their significant cytotoxic and antitumor effects. However, Glycyrrhiza iconica, an endemic species to Turkey, was not investigated in terms of its anticancer secondary metabolites previously. PURPOSE This study aimed to isolate the cytotoxic compounds from G. iconica through bioactivity-guided fractionation and to elucidate mechanisms of action of the most potent compounds. METHODS Total MeOH extract and CHCl3, EtOAc, n-buOH and rH2O subextracts were prepared from G. iconica roots. Sequential chromatographic techniques were conducted for the isolation studies. The chemical structures of the isolates were established based on NMR and HR-MS analysis. Sulforhodamine B assay was used to evaluate the cytotoxic activity of extracts, main fractions as well as isolates against hepatocellular (Huh7), breast (MCF7) and colorectal (HCT116) cancer cell lines. The mechanisms underlying the cytotoxicity of the most active compounds in Huh7 cells were elucidated by using Hoechst staining, Fluorescence-activated cell sorting and Western blot assays. RESULTS A new dihydrochalcone, iconichalcone (1) along with 15 known phenolic compounds were isolated from the active CHCl3, EtOAc and n-buOH subextracts. Compounds 2-5, 7-16 were found to be responsible for the in vitro cytotoxic activity of G. iconica against all tested cancer cell lines with IC50 values ranging from 2.4 to 33 µM. Amongst these compounds, licoricidin (10), dehydroglyasperin C (12), iconisoflaven (13) and 1-methoxyficifolinol (15) were found to be the most active compounds according to SRB and real time bioactivity assays and submitted to further mechanistic investigations in Huh7 cells. Compounds 10, 12, 13 and 15 caused accumulation of cells in different phases of cell cycle. Moreover, 10, 12, 13 and 15 induced apoptosis through caspase activation. Besides, 12 showed activation of p53 expression and thus G2/M arrest as well as a condensed nuclei, established very promising results. CONCLUSION The results demonstrated that the aforementioned compounds, particularly 12 could be potential lead molecules for anticancer drug development that deserve further in vivo and clinical investigations.

Abstract
The scope of this review is to sensitize the natural product chemists to the underestimated problem related to artifact, comprising contaminants and improbable natural compounds. This review wants to give an overview about the various facets of this problem and to provide some hints to avoid incurring these situations. It does not pretend to report exhaustively about all the cases available in literature. The issue of artifacts has always existed and is quite impossible to completely eliminate because the results of phytochemical analysis are known only at the end of the work and in many cases there is not the possibility to compare the results. Therefore, it is important to take the necessary precautions during the workout in order to minimize the possibility that an unexpected event may occur. In second instance, anyone involved in these studies should increase the level of self-criticism with respect to the obtained experimental results.

Abstract
Vestitol and neovestitol are bioactive isoflavonoids isolated from Brazilian red propolis, a unique Apis melifera type of propolis botanically originated from Dalbergia ecastophyllum. Although these molecules have relevant biological effects, including anticancer and immunomodulatory activities, their mechanism(s) of action and the affected pathways remain largely unknown. Here, we carried out a pharmacogenomic analysis to investigate the effects of vestitol and neovestitol on the whole-genome expression in human tumor cells, particularly cancer-related target proteins. HeLa cells were exposed to the compounds at IC20 and genomic information of treated cells was analyzed using the Illumina transcriptome system and GeneGo MetaCore software. Our results showed that vestitol (IC20 = 214.7 μM) reduced the expression of genes enrolled with the alpha tubulin (fold -3.7), tubulin in microtubules (fold -3.7), and histone h3 (fold = -3.03), and that treatment with neovestitol (IC20 = 102.91 μM) downregulated prostaglandin E synthase gene (fold = -3.12), which are considered ideal targets for anticancer therapy. These data open avenues for the study of vestitol and neovestitol as potential promising candidates for anticancer therapy. Toxicological, non-clinical, and clinical validation of the findings presented herein is needed.
