(Elsevier Inc., 2022-07-27T00:00:00) Tuli, Hardeep Singh; Sak, Katrin; Garg, Vivek Kumar; Kumar, Ajay; Adhikary, Shubham; Kaur, Ginpreet; Parashar, Nidarshana Chaturvedi; Parashar, Gaurav; Mukherjee, Tapan Kumar; Sharma, Uttam; Jain, Aklank; Mohapatra, Ranjan K.; Dhama, Kuldeep; Kumar, Manoj; Singh, Tejveer
Cancer is being considered as a serious threat to human health globally due to limited availability and efficacy of therapeutics. In addition, existing chemotherapeutic drugs possess a diverse range of toxic side effects. Therefore, more research is welcomed to investigate the chemo-preventive action of plant-based metabolites. Ampelopsin (dihydromyricetin) is one among the biologically active plant-based chemicals with promising anti-cancer actions. It modulates the expression of various cellular molecules that are involved in cancer progressions. For instance, ampelopsin enhances the expression of apoptosis inducing proteins. It regulates the expression of angiogenic and metastatic proteins to inhibit tumor growth. Expression of inflammatory markers has also been found to be suppressed by ampelopsin in cancer cells. The present review article describes various anti-tumor cellular targets of ampelopsin at a single podium which will help the researchers to understand mechanistic insight of this phytochemical. � 2022 The Authors
Galangin: A metabolite that suppresses anti-neoplastic activities through modulation of oncogenic targets
(SAGE Publications Inc., 2021-12-14T00:00:00) Tuli, Hardeep Singh; Sak, Katrin; Adhikary, Shubham; Kaur, Ginpreet; Aggarwal, Diwakar; Kaur, Jagjit; Kumar, Manoj; Parashar, Nidarshana Chaturvedi; Parashar, Gaurav; Sharma, Uttam; Jain, Aklank
With the dramatic increase in cancer incidence all over the world in the last decades, studies on identifying novel efficient anti-cancer agents have been intensified. Historically, natural products have represented one of the most important sources of new lead compounds with a wide range of biological activities. In this article, the multifaceted anti-cancer action of propolis-derived flavonoid, galangin, is presented, discussing its antioxidant, anti-inflammatory, antiproliferative, pro-apoptotic, anti-angiogenic, and anti-metastatic effects in various cancer cells. In addition, co-effects with standard chemotherapeutic drugs as well as other natural compounds are also under discussion, besides highlighting modern nanotechnological advancements for overcoming the low bioavailability issue characteristic of galangin. Although further studies are needed for confirming the anti-cancer potential of galangin in vivo malignant systems, exploring this natural compound might open new perspectives in molecular oncology. � 2021 by the Society for Experimental Biology and Medicine.
Molecular mechanisms of action of epigallocatechin gallate in cancer: Recent trends and advancement
(Academic Press, 2020-05-24T00:00:00) Aggarwal, Vaishali; Tuli, Hardeep Singh; Tania, Mousumi; Srivastava, Saumya; Ritzer, Erin E.; Pandey, Anjana; Aggarwal, Diwakar; Barwal, Tushar Singh; Jain, Aklank; Kaur, Ginpreet; Sak, Katrin; Varol, Mehmet; Bishayee, Anupam
Epigallocatechin gallate (EGCG), also known as epigallocatechin-3-gallate, is an ester of epigallocatechin and gallic acid. EGCG, abundantly found in tea, is a polyphenolic flavonoid that has the potential to affect human health and disease. EGCG interacts with various recognized cellular targets and inhibits cancer cell proliferation by inducing apoptosis and cell cycle arrest. In addition, scientific evidence has illustrated the promising role of EGCG in inhibiting tumor cell metastasis and angiogenesis. It has also been found that EGCG may reverse drug resistance of cancer cells and could be a promising candidate for synergism studies. The prospective importance of EGCG in cancer treatment is owed to its natural origin, safety, and low cost which presents it as an attractive target for further development of novel cancer therapeutics. A major challenge with EGCG is its low bioavailability which is being targeted for improvement by encapsulating EGCG in nano-sized vehicles for further delivery. However, there are major limitations of the studies on EGCG, including study design, experimental bias, and inconsistent results and reproducibility among different study cohorts. Additionally, it is important to identify specific EGCG pharmacological targets in the tumor-specific signaling pathways for development of novel combined therapeutic treatments with EGCG. The present review highlights the ongoing development to identify cellular and molecular targets of EGCG in cancer. Furthermore, the role of nanotechnology-mediated EGCG combinations and delivery systems will also be discussed. � 2020 Elsevier Ltd
Path of Silibinin from diet to medicine: A dietary polyphenolic flavonoid having potential anti-cancer therapeutic significance
(Academic Press, 2020-10-29T00:00:00) Tuli, Hardeep Singh; Mittal, Sonam; Aggarwal, Diwakar; Parashar, Gaurav; Parashar, Nidarshana Chaturvedi; Upadhyay, Sushil Kumar; Barwal, Tushar Singh; Jain, Aklank; Kaur, Ginpreet; Savla, Raj; Sak, Katrin; Kumar, Manoj; Varol, Mehmet; Iqubal, Ashif; Sharma, Anil Kumar
In the last few decades, targeting cancer by the use of dietary phytochemicals has gained enormous attention. The plausible reason and believe or mind set behind this fact is attributed to either lesser or no side effects of natural compounds as compared to the modern chemotherapeutics, or due to their conventional use as dietary components by mankind for thousands of years. Silibinin is a naturally derived polyphenol (a flavonolignans), possess following biochemical features; molecular formula C25H22O10, Molar mass: 482.44 g/mol, Boiling point 793 �C, with strikingly high antioxidant and anti-tumorigenic properties. The anti-cancer properties of Silibinin are determined by a variety of cellular pathways which include induction of apoptosis, cell cycle arrest, inhibition of angiogenesis and metastasis. In addition, Silibinin controls modulation of the expression of aberrant miRNAs, inflammatory response, and synergism with existing anti-cancer drugs. Therefore, modulation of a vast array of cellular responses and homeostatic aspects makes Silibinin an attractive chemotherapeutic agent. However, like other polyphenols, the major hurdle to declare Silibinin a translational chemotherapeutic agent, is its lesser bioavailability. After summarizing the chemistry and metabolic aspects of Silibinin, this extensive review focuses on functional aspects governed by Silibinin in chemoprevention with an ultimate goal of summarizing the evidence supporting the chemopreventive potential of Silibinin and clinical trials that are currently ongoing, at a single platform. � 2020 Elsevier Ltd
Temozolomide and flavonoids against glioma: from absorption and metabolism to exosomal delivery
(Springer Science and Business Media Deutschland GmbH, 2023-08-11T00:00:00) Verma, Priyanka; Joshi, Hemant; Singh, Tejveer; Sharma, Bunty; Sharma, Ujjawal; Ramniwas, Seema; Rana, Rashmi; Gupta, Madhu; Kaur, Ginpreet; Tuli, Hardeep Singh
Patients with glioblastoma multiforme and anaplastic astrocytoma are treated with temozolomide. Although it has been demonstrated that temozolomide increases GBM patient survival, it has also been connected to negative immune-related adverse effects. Numerous research investigations have shown that flavonoids have strong antioxidant and chemo-preventive effects. Consequently, it might lessen chemotherapeutic medicines� side effects while also increasing therapeutic effectiveness. The need for creating innovative, secure, and efficient drug carriers for cancer therapy has increased over time. Recent research indicates that exosomes have enormous potential to serve as carriers and cutting-edge drug delivery systems to the target cell. In recent years, researchers have been paying considerable attention to exosomes because of their favorable biodistribution, biocompatibility, and low immunogenicity. In the present review, the mechanistic information of the anti-glioblastoma effects of temozolomide and flavonoids coupled with their exosomal delivery to the targeted cell has been discussed. In addition, we discuss the safety aspects of temozolomide and flavonoids against glioma. The in-depth information of temozolomide and flavonoids action via exosomal delivery can unravel novel strategies to target Glioma. � 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.
