BHUSARE NILAM, KUMAR MAUSHMI. A review on potential heterocycles for the treatment of glioblastoma targeting receptor tyrosine kinases. Oncol Res 2024; 32:849-875. [PMID: 38686058 PMCID: PMC11055995 DOI: 10.32604/or.2024.047042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Accepted: 01/10/2024] [Indexed: 05/02/2024] Open
Abstract
Glioblastoma, the most aggressive form of brain tumor, poses significant challenges in terms of treatment success and patient survival. Current treatment modalities for glioblastoma include radiation therapy, surgical intervention, and chemotherapy. Unfortunately, the median survival rate remains dishearteningly low at 12-15 months. One of the major obstacles in treating glioblastoma is the recurrence of tumors, making chemotherapy the primary approach for secondary glioma patients. However, the efficacy of drugs is hampered by the presence of the blood-brain barrier and multidrug resistance mechanisms. Consequently, considerable research efforts have been directed toward understanding the underlying signaling pathways involved in glioma and developing targeted drugs. To tackle glioma, numerous studies have examined kinase-downstream signaling pathways such as RAS-RAF-MEK-ERK-MPAK. By targeting specific signaling pathways, heterocyclic compounds have demonstrated efficacy in glioma therapeutics. Additionally, key kinases including phosphatidylinositol 3-kinase (PI3K), serine/threonine kinase, cytoplasmic tyrosine kinase (CTK), receptor tyrosine kinase (RTK) and lipid kinase (LK) have been considered for investigation. These pathways play crucial roles in drug effectiveness in glioma treatment. Heterocyclic compounds, encompassing pyrimidine, thiazole, quinazoline, imidazole, indole, acridone, triazine, and other derivatives, have shown promising results in targeting these pathways. As part of this review, we propose exploring novel structures with low toxicity and high potency for glioma treatment. The development of these compounds should strive to overcome multidrug resistance mechanisms and efficiently penetrate the blood-brain barrier. By optimizing the chemical properties and designing compounds with enhanced drug-like characteristics, we can maximize their therapeutic value and minimize adverse effects. Considering the complex nature of glioblastoma, these novel structures should be rigorously tested and evaluated for their efficacy and safety profiles.

Artemisia sieberi Besser essential oil inhibits the growth and migration of breast cancer cells via induction of S-phase arrest, caspase-independent cell death and downregulation of ERK. JOURNAL OF ETHNOPHARMACOLOGY 2023; 312:116492. [PMID: 37059248 DOI: 10.1016/j.jep.2023.116492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 03/30/2023] [Accepted: 04/11/2023] [Indexed: 05/08/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Artemisia sieberi Besser is a medicinal herb that has been traditionally used across the Middle East for the treatment of cancer. Further pharmacological studies on its extracts revealed that they possess cytotoxic activity against certain cancer cells, however, there were no studies conducted on the anticancer potential of Artemisia sieberi essential oil (ASEO). AIM OF THE STUDY To evaluate the anticancer potential of ASEO, elucidate the oil's mode of action for the first time and investigate its chemical composition. MATERIALS AND METHODS Artemisia sieberi was collected from Hail, Saudi Arabia, and its essential oil was obtained via hydrodistillation. The oil's activity against HCT116, HepG2, A549 and MCF-7 cells was assessed using SRB assay, while its anti-metastatic potential was assessed via a migration assay. Cell-cycle analysis and apoptosis assay were conducted via flow cytometry, while protein expression levels were investigated using Western blotting. The oil's chemical constituents were identified using GCMS. RESULTS ASEO exerted its highest cytotoxic activity against MCF-7 with an IC50 value of 38.7 μg/ml. Further studies showed that the oil inhibited MCF-7 cells' migration, induced S-phase arrest and apoptosis. Western blot analysis showed no change in the expression level of caspase-3 after treatment, indicating the induction of caspase-independent apoptosis-like cell death in MCF-7. Treatment of MCF-7 with the oil resulted in downregulation of the protein expression levels of total ERK and its downstream target, LC3, indicating that any potential activation of the ERK signalling pathway during the cancer cells' growth would be inhibited. Finally, GCMS analysis identified the oil's major components as cis-crysanthenyl acetate (48.56%), davanone (10.28%), 1,8-cineole (6.81%) and caryophyllene diepoxide (5.34%), whereby it is suggested that these compounds might be responsible for the oil's bioactivity. CONCLUSION ASEO possessed in vitro anticancer activity and modulated the ERK signalling pathway. This is the first study to explore the anticancer potential of ASEO in detail and reflects the significance of investigating essential oils from medicinal plants that have been traditionally used against cancer. This work might pave the way for further in vivo studies that could result in developing the oil into a natural effective anticancer treatment.

J Transl Med 2023; 21:532. [PMID: 37550679 PMCID: PMC10405494 DOI: 10.1186/s12967-023-04332-y] [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: 03/24/2023] [Accepted: 07/08/2023] [Indexed: 08/09/2023] Open
Abstract
BACKGROUND Glioblastoma (GBM) is a brain tumor with the highest level of malignancy and the worst prognosis in the central nervous system. Mitochondrial metabolism plays a vital role in the occurrence and development of cancer, which provides critical substances to support tumor anabolism. Mito-LND is a novel small-molecule inhibitor that can selectively inhibit the energy metabolism of tumor cells. However, the therapeutic effect of Mito-LND on GBM remains unclear. METHODS The present study evaluated the inhibitory effect of Mito-LND on the growth of GBM cells and elucidated its potential mechanism. RESULTS The results showed that Mito-LND could inhibit the survival, proliferation and colony formation of GBM cells. Moreover, Mito-LND induced cell cycle arrest and apoptosis. Mechanistically, Mito-LND inhibited the activity of mitochondrial respiratory chain complex I and reduced mitochondrial membrane potential, thus promoting ROS generation. Importantly, Mito-LND could inhibit the malignant proliferation of GBM by blocking the Raf/MEK/ERK signaling pathway. In vivo experiments showed that Mito-LND inhibited the growth of GBM xenografts in mice and significantly prolonged the survival time of tumor-bearing mice. CONCLUSION Taken together, the current findings support that targeting mitochondrial metabolism may be as a potential and promising strategy for GBM therapy, which will lay the theoretical foundation for further clinical trials on Mito-LND in the future.

Abstract
Glioblastoma (GBM) is a malignant tumor characterized by poor prognosis and low overall survival (OS) rate. Identification of novel biological markers for the diagnosis and treatment of GBM is crucial to developing interventions to improve patient survival. GNA13, a member of the G12 family, has been reported to play important roles in a variety of biological processes involved in tumorigenesis and development. However, its role in GBM is currently unknown. Here, we explored the expression patterns and functions of GNA13 in GBM, as wells its impact on metastasis process. Results showed that GNA13 was downregulated in GBM tissues and correlated with poor prognosis of GBM. Downregulation of GNA13 promoted the migration, invasion and proliferation of GBM cells; whereas its overexpression abolished these effects. Western blots revealed that GNA13 knockdown and overexpression upregulated and inhibited the phosphorylation of ERKs, respectively. Moreover, GNA13 was the upstream of ERKs signaling to regulating ERKs phosphorylation level. Furthermore, U0126 alleviated the metastasis effect induced by GNA13 knockdown. Bioinformatics analyses and qRT-PCR experiments demonstrated that GNA13 could regulate FOXO3, a downstream signaling molecule of ERKs pathway. Overall, our results demonstrate that GNA13 expression is negatively correlated with GBM and can suppress tumor metastasis by inhibiting the ERKs signaling pathway and upregulating FOXO3 expression.

Involvement of Phytochemical-Encapsulated Nanoparticles' Interaction with Cellular Signalling in the Amelioration of Benign and Malignant Brain Tumours. MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27113561. [PMID: 35684498 PMCID: PMC9182026 DOI: 10.3390/molecules27113561] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Revised: 05/24/2022] [Accepted: 05/24/2022] [Indexed: 12/05/2022]
Abstract
Brain tumours have unresolved challenges that include delay prognosis and lower patient survival rate. The increased understanding of the molecular pathways underlying cancer progression has aided in developing various anticancer medications. Brain cancer is the most malignant and invasive type of cancer, with several subtypes. According to the WHO, they are classified as ependymal tumours, chordomas, gangliocytomas, medulloblastomas, oligodendroglial tumours, diffuse astrocytomas, and other astrocytic tumours on the basis of their heterogeneity and molecular mechanisms. The present study is based on the most recent research trends, emphasising glioblastoma cells classified as astrocytoma. Brain cancer treatment is hindered by the failure of drugs to cross the blood–brain barrier (BBB), which is highly impregnableto foreign molecule entry. Moreover, currently available medications frequently fail to cross the BBB, whereas chemotherapy and radiotherapy are too expensive to be afforded by an average incomeperson and have many associated side effects. When compared to our current understanding of molecularly targeted chemotherapeutic agents, it appears that investigating the efficacy of specific phytochemicals in cancer treatment may be beneficial. Plants and their derivatives are game changers because they are efficacious, affordable, environmentally friendly, faster, and less toxic for the treatment of benign and malignant tumours. Over the past few years, nanotechnology has made a steady progress in diagnosing and treating cancers, particularly brain tumours. This article discusses the effects of phytochemicals encapsulated in nanoparticles on molecular targets in brain tumours, along with their limitations and potential challenges.

Abstract
Background and purpose Glioblastoma multiforme (GBM) is the most invasive type of cancer which starts inside the brain. GBM cells were found to have similar properties to glioblastoma cancer stem cells. CD44 can be used as a marker of the cancer stem cells in a subset of glioblastoma tumor cells. Recent studies showed that CD44 is involved in developing cancer cells via the protein kinase B (PKB or AKT) signaling pathway. Therefore, this study aimed to investigate the CD44 mRNA silencing effects on the glioblastoma cell cycle via AKT signaling pathway. Experimental approach To determine CD44 expression in the samples of the patients with GBM, we used the analysis of data extracted from TCGA database. qRT-PCR and western blotting were used to evaluate the expression level of genes and proteins. Different cell cycles were evaluated by DAPI staining and flow cytometry. Findings/Results Bioinformatics results showed that CD44 expression level in GBM tumor samples is higher than in normal samples. Effects of poly (ethylene imine)-polyethylene glycol (PEI-PEG)-loaded CD44 siRNA in cell cycle showed that CD44 silencing could inhibit cell cycle in G0-G1 phase by more than 20% compared to the negative control (P < 0.05). Furthermore, PEI-PEG-loaded CD44 siRNA reduces the expression of cyclin D1 and CKD-4. According to our findings, this structure also prevented AKT phosphorylation at Thr-308 and Ser-473. Conclusion and implications Our results suggest that PEI-PEG-loaded CD44 siRNA may attenuate the cell cycle by suppressing AKT signaling pathway.

Demethylzeylasteral (T-96) initiates extrinsic apoptosis against prostate cancer cells by inducing ROS-mediated ER stress and suppressing autophagic flux. Biol Res 2021; 54:27.

Abstract
Background Demethylzeylasteral (T-96) is a pharmacologically active triterpenoid monomer extracted from Tripterygium wilfordii Hook F (TWHF) that has been reported to exhibit anti-neoplastic effects against several types of cancer cells. However, the potential anti-tumour effects of T-96 against human Prostate cancer (CaP) cells and the possible underlying mechanisms have not been well studied. Results In the current study, T-96 exerted significant cytotoxicity to CaP cells in vitro and induced cell cycle arrest at S-phase in a dose-dependent manner. Mechanistically, T-96 promoted the initiation of autophagy but inhibited autophagic flux by inducing ROS-mediated endoplasmic reticulum (ER) stress which subsequently activated the extrinsic apoptosis pathway in CaP cells. These findings implied that T-96-induced ER stress activated the caspase-dependent apoptosis pathway to inhibit proliferation of CaP cells. Moreover, we observed that T-96 enhances the sensitivity of CaP cells to the chemotherapeutic drug, cisplatin. Conclusions Taken together, our data demonstrated that T-96 is a novel modulator of ER stress and autophagy, and has potential therapeutic applications against CaP in the clinic.

Recent developments in mitogen activated protein kinase inhibitors as potential anticancer agents. Bioorg Chem 2021; 114:105161.

Abstract
The mitogen activated protein kinase (MAPK) belongs to group of kinase that links the extracellular stimuli to intracellular response. The MAPK signalling pathway (RAS-RAF-MEK-ERK) involved in different pathological conditions like cancer, caused due to genetic or any other factor such as physical or environmental. Many studies have been conducted on the pathological view of MAPK cascade and its associated element like RAS, RAF, MEK, ERK or its isoforms, and still the research is going on particularly with respect to its activation, regulation and inhibition. The MAPK signalling pathway has become the area of research to identify new target for the management of cancer. A number of heterocyclics are key to fight with the cancer associated with these enzymes thus give some hope in the management of cancer by inhibiting MAPK cascade. In the present article, we have focussed on MAPK signalling pathway and role of different heterocyclic scaffolds bearing nitrogen, sulphur and oxygen and about their potential to block MAPK signalling pathway. The heterocyclics are gaining importance due to high potency and selectivity with less off-target effects against different targets involved in the MAPK signalling pathway. We have tried to cover recent advancements in the MAPK signalling pathway inhibitors with an aim to get better understanding of the mechanism of action of the compounds. Several compounds in the preclinical and clinical studies have been thoroughly dealt with. In addition to the synthetic compounds, a significant number of natural products containing heterocyclic moieties as MAPK signalling pathway inhibitors have been put together. The structure activity relationship along with docking studies have been discussed to apprehend the mechanistic studies of various compounds that will ultimately help to design and develop more MAPK signalling pathway inhibitors.

Abstract
A paradigm shift in treating the most aggressive and malignant form of glioma is continuously evolving; however, these strategies do not provide a better life and survival index. Currently, neurosurgical debulking, radiotherapy, and chemotherapy are the treatment options available for glioma, but these are non-specific in action. Patients invariably develop resistance to these therapies, leading to recurrence and death. Receptor Tyrosine Kinases (RTKs) are among the most common cell surface proteins in glioma and play a significant role in malignant progression; thus, these are currently being explored as therapeutic targets. RTKs belong to the family of cell surface receptors that are activated by ligands which in turn activates two major downstream signaling pathways via Rapidly Accelerating Sarcoma/mitogen activated protein kinase/extracellular-signal-regulated kinase (Ras/MAPK/ERK) and phosphatidylinositol 3-kinase/a serine/threonine protein kinase/mammalian target of rapamycin (PI3K/AKT/mTOR). These pathways are critically involved in regulating cell proliferation, invasion, metabolism, autophagy, and apoptosis. Dysregulation in these pathways results in uncontrolled glioma cell proliferation, invasion, angiogenesis, and cancer progression. Thus, RTK pathways are considered a potential target in glioma management. This review summarizes the possible risk factors involved in the growth of glioblastoma (GBM). The role of RTKs inhibitors (TKIs) and the intracellular signaling pathways involved, small molecules under clinical trials, and the updates were discussed. We have also compiled information on the outcomes from the various endothelial growth factor receptor (EGFR)-TKIs-based nanoformulations from the preclinical and clinical points of view. Aided by an extensive literature search, we propose the challenges and potential opportunities for future research on EGFR-TKIs-based nanodelivery systems.

[PMID: 32908894 PMCID: PMC7468608 DOI: 10.1155/2020/4929053] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/28/2020] [Accepted: 07/27/2020] [Indexed: 11/23/2022]
Abstract
Background Cancer remains a major clinical challenge because of the lack of effective drug for its treatment. To find out novel cancer chemotherapeutic molecules, we explored the anticancer effect of novel imidazopyridine compound 9i and also investigated the underlying molecular mechanism. Methods Human cervical cancer cell (HeLa) viability was measured by an MTT assay after treatment with compound 9i. Clonogenicity of HeLa cells was investigated by an in vitro colony formation assay. Cell death was visualized by propidium iodide (PI) staining. Fluorescence-activated cell sorting (FACS) was used to determine apoptosis and mitochondrial membrane potential in HeLa cells. The expression level of apoptosis-related proteins was also determined by western blot. Results Compound 9i suppressed HeLa cell viability in a time- and dose-dependent manner. Compound 9i induced mitochondrial outer membrane permeabilization (MOMP), activated caspase cascade, and finally resulted in apoptosis. Conclusion Compound 9i induces mitochondrial pathway-mediated apoptosis in human cervical cancer cells, suggesting that 9i could be a potential lead compound to be developed as a cancer therapeutic molecule.

AKT Inhibitor SC66 Inhibits Proliferation and Induces Apoptosis in Human Glioblastoma Through Down-Regulating AKT/β-Catenin Pathway. Front Pharmacol 2020; 11:1102. [PMID: 32848734 PMCID: PMC7411127 DOI: 10.3389/fphar.2020.01102] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2020] [Accepted: 07/06/2020] [Indexed: 12/19/2022] Open
Abstract
Glioblastoma multiforme (GBM) is the most common intracranial malignancy in adults with the highest degree of malignancy and mortality. Due to its nature of diffuse invasiveness and high migration, GBM lacks an effective treatment strategy and is associated with poor prognosis. SC66 is a novel AKT inhibitor that has been reported to exert antiproliferative activity in many types of cancer cells. However, it remains unclear whether SC66 has antitumor effects in GBM. In this study, we found SC66 obviously suppressed U87 and U251 cell proliferation and EMT- mediated cell migration and invasion. Moreover, SC66 induced GBM cells apoptosis and arrested cell cycle in G0/G1 phase. Furthermore, SC66 also downregulated AKT signaling pathway in a concentration dependent manner. We also found the level of β-catenin nuclear translocation was prominently downregulated after SC66 treatment. Meanwhile, TCF/LEF luciferase report assay indicated that the activity of TCF/LEF was remarkably suppressed. Elevating β-catenin activity by using IM12 rescued SC66 inhibition-mediated GBM cell proliferation and metastasis. In addition, SC66 showed significantly suppressed the tumorigenicity compared to the control group in the xenograft mouse model. In conclusion, our study demonstrated that SC66 exerts prominently antitumor efficiency in GBM cells in vivo and in vitro by downregulated AKT/β-catenin pathway.

Abstract
Cancer, still in the limelight due to its dreadful nature, shows overexpression of multiple signaling macromolecules leading to failure of many chemotherapeutic agents and acquired resistance to chemotherapy. These factors highlight the significance of shifting toward targeted therapy in cancer research. Recently, ERKs (ERK1 and 2) have been established as a promising target for the management of various types of solid tumors, due to their aberrant involvement in cell growth and progression. Several ERKs inhibitors have reached clinical trials for the management of cancer and their derivatives are being continuously reported with noteworthy anticancer effect. This review highlights the recent reports on various chemical classes involved in the development of ERKs inhibitors along with their in vitro and in vivo activity and structure-activity relationship profile.

Vascul Pharmacol 2019; 116:16-23. [PMID: 30822571 DOI: 10.1016/j.vph.2019.02.005] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2018] [Revised: 02/23/2019] [Accepted: 02/25/2019] [Indexed: 12/18/2022]
Abstract
Long noncoding RNA-steroid receptor RNA activator (LncRNA-SRA) is transcribed from a class of noncoding genes, and plays a critical role in regulating cell proliferation. However, the effect of lncRNA-SRA remains unclear in vascular proliferative diseases. In the present study, we overexpressed lncRNA-SRA in vitro, then investigated the biological consequences. A vascular damage mice model was constructed by performing femoral artery wire injury. LncRNA-SRA was overexpressed in the injured arteries, and significantly promoted the expression of ki67, thereby caused an overall increase in neointima formation. LncRNA-SRA overexpression led to the proliferation and migration of vascular smooth muscle cells (VSMCs). By stimulating the phosphorylation of MEK, ERK and CREB (cyclic nucleotide responsive element binding protein), lncRNA-SRA promoted VSMC proliferation. Meanwhile, these effects were blocked by the MEK inhibitor U0126. Therefore, lncRNA-SRA promoted VSMC proliferation by activating the MEK-ERK-CREB pathway. LncRNA-SRA could be a promising therapeutic target in vascular diseases characterized by neointimal hyperplasia.

Raf-ERK1/2 signalling pathways mediate steroid hormone synthesis in bovine ovarian granulosa cells. Reprod Domest Anim 2019; 54:741-749.

Abstract
Steroid hormones are required for normal reproductive function of female. The aim of this study was to investigate the role of Raf-ERK1/2 on steroid hormone synthesis in bovine ovarian granulosa cells. Immunohistochemistry assay showed that both B-Raf and C-Raf were expressed in granulosa cells, theca cells and Sertoli cells. The protein expression of Raf or ERK1/2 was clearly decreased by Raf inhibitor GSK2118436 or ERK1/2 inhibitor SCH772984, respectively (p < 0.05). In addition, western blotting was performed for investigating the crosstalk between Raf and ERK1/2, the data showed that Raf positively regulated ERK1/2, whereas ERK1/2 had a negative feedback effect on Raf. The biosynthesis of oestradiol or testosterone was significantly decreased by treatment with GSK2118436 or SCH772984 (p < 0.05). Conversely, the progesterone biosynthesis was clearly increased by treatment with those inhibitors (p < 0.05). Furthermore, the mRNA expression of STAR, aromatase and CYP17 was blocked by Raf-ERK1/2 signalling inhibition, which oppositely induced the mRNA expression of CYP11. Together, these findings suggested that Raf-ERK1/2 signalling pathways mediate steroid hormone synthesis via affecting the expression of steroidogenic enzymes.
