Abstract: Cancer cells are usually recognized as foreign particles by the immune cells. Mounting evidence suggest an important link between toll-like receptors (TLRs) and carcinogenesis. This review article focused on the role of TLRs, especially TLR4, in breast cancer. Research data on TLRs and cancer was explored in PubMed, Scopus, Google Scholar and reviewed. Although some pioneer works are referenced, papers published in the last ten years were mostly cited. TLRs are widely investigated pattern recognition receptors (PRR), and TLR4 is the most studied TLRs, implicated with the occurrence of several types of cancers, including breast cancer. TLR4 activation occurs via the binding of its ligand lipopolysaccharide (LPS), a component of the outer membrane of gram-negative bacteria. Upon LPS binding, TLR4 dimerizes and recruits downstream signalling and/or adapter molecules, leading to gene expression related to cancer cell proliferation, survival, invasion, and metastasis. Although LPS/TLR4 signalling seems a single signal transduction pathway, the TLR4 activation results in the activation of multiple erse intracellular networks with huge cellular responses in both immune and cancer cells. The role of TLR4 in the growth, invasion, and metastasis of breast cancer is attracting huge attention in oncology research. Several clinical and preclinical studies utilize both TLR4 agonists and antagonists as a treatment option for cancer therapy, either as monotherapy or adjuvants for vaccine development. This review narrates the role of LPS/TLR4 signalling in breast cancer development and future prospects for targeting LPS/TLR4 axis in the treatment of breast cancer.

Abstract: Hesperidin belongs to flavanones class of flavonoids and is known to possess broad-spectrum applicability to prevent dreadful diseases such as cardiovascular disease, neurodegeneration, and cancer. The reported anticancer effects of hesperidin have been found to be associated with its anti-oxidant and anti-inflammatory activities. Hesperidin interacts with numerous recognized cellular targets and inhibits cancer cell proliferation by inducing apoptosis and cell cycle arrest. In addition, evidence has suggested its promising role in inhibiting tumor cell metastasis, angiogenesis, and chemoresistance. The present mini-review highlights the ongoing development to identify hesperidin targets in cancer. Furthermore, the potential of nano technology-based hesperidin combinations and delivery systems will also be discussed. Overall, this review highlights all the possible molecular targets affected by hesperidin in tumor cells on a single platform. Experimental findings from numerous studies have demonstrated the anticancer effects of hesperidin (Hesp) to be associated with anti-oxidant and anti-inflammatory activities along with its potential role in inhibiting the tumor cell metastasis and angiogenesis. Additionally, Hesp can also reverse drug resistance of cancer cells, which make it a promising candidate to be used in combination with existing anti-cancer drugs. This review will be helpful for upcoming researchers and scientific community to find out complete capsular package about cancer drug targets of Hesp and its role in modulating various important hallmarks of cancer.

Abstract: SARS-CoV-2 is a coronavirus, and the infection by SARS-CoV-2, termed as COVID-19, was first reported in Wuhan, China, at the end of 2019, and this outbreak became a pandemic in February of 2020. Till now, there is no effective drug or vaccine against this virus that can make a complete cure however, a number of drugs are in trials. In this review, we have focused on an alternative therapeutic approach using natural products utilizing the host anti-viral responses for resolving COVID-19 pathogenesis. We have searched databases like PubMed, Scopus, Web of Science, and Google Scholar for articles related to natural products and viral diseases, with a specific focus on coronaviruses, as well as other RNA viruses and recent updates on the COVID-19 pandemic, and collected articles and reviewed them comprehensively. Scientific studies clarified the viral pathogenesis that involved viral entrance into host cells and anti-viral response inside the cells, which can be effectively targeted by numerous natural compounds from different sources. Many of these compounds can potentially target viral genomic material or protein machinery. Natural products that were found effective against other coronaviruses, especially SARS-CoV or MERS-CoV (which emerged in 2002 and 2012, respectively), might be effective against SARS-CoV-2 due to their structural similarities. COVID-19 pandemic is a global emergency thus, urgent drug development is necessary. Natural products can be the biggest source of drugs, as they have been found to be effective in other coronaviruses previously however, time is required to establish the clinical success of these drugs for clinical applications.

Abstract: Reactive oxygen species (ROS) play a pivotal role in biological processes and continuous ROS production in normal cells is controlled by the appropriate regulation between the silver lining of low and high ROS concentration mediated effects. Interestingly, ROS also dynamically influences the tumor microenvironment and is known to initiate cancer angiogenesis, metastasis, and survival at different concentrations. At moderate concentration, ROS activates the cancer cell survival signaling cascade involving mitogen-activated protein kinase/extracellular signal-regulated protein kinases 1/2 (MAPK/ERK1/2), p38, c-Jun N-terminal kinase (JNK), and phosphoinositide-3-kinase/ protein kinase B (PI3K/Akt), which in turn activate the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), matrix metalloproteinases (MMPs), and vascular endothelial growth factor (VEGF). At high concentrations, ROS can cause cancer cell apoptosis. Hence, it critically depends upon the ROS levels, to either augment tumorigenesis or lead to apoptosis. The major issue is targeting the dual actions of ROS effectively with respect to the concentration bias, which needs to be monitored carefully to impede tumor angiogenesis and metastasis for ROS to serve as potential therapeutic targets exogenously/endogenously. Overall, additional research is required to comprehend the potential of ROS as an effective anti-tumor modality and therapeutic target for treating malignancies.

Abstract: Phytochemicals are being used for thousands of years to prevent dreadful malignancy. Side effects of existing allopathic treatment have also initiated intense research in the field of bioactive phytochemicals. Gallic acid, a natural polyphenolic compound, exists freely as well as in polymeric forms. The anti-cancer properties of gallic acid are indomitable by a variety of cellular pathways such as induction of programmed cell death, cell cycle apprehension, reticence of vasculature and tumor migration, and inflammation. Furthermore, gallic acid is found to show synergism with other existing chemotherapeutic drugs. Therefore, the antineoplastic role of gallic acid suggests its promising therapeutic candidature in the near future. The present review describes all these aspects of gallic acid at a single platform. In addition nanotechnology-mediated approaches are also discussed to enhance bioavailability and therapeutic efficacy.

Abstract: Currently, the present world is facing a new deadly challenge against a pandemic disease called COVID-19, which is caused by a coronavirus, named SARS-CoV-2. To date, there is no drug or vaccine that can treat COVID-19 completely, but some drugs have been used primarily, and they are in different stages of clinical trials. This review article discussed and compared those drugs which are running ahead in COVID-19 treatments. We have explored PUBMED, SCOPUS, WEB OF SCIENCE, as well as press release of WHO, NIH and FDA for articles about COVID-19, and reviewed them. Drugs like favipiravir, remdesivir, lopinavir/ritonavir, hydroxychloroquine, azithromycin, ivermectin, corticosteroids and interferons have been found effective in some extents, and partially approved by FDA and WHO to treat COVID-19 at different phases of pandemic. However, some of these drugs have been disapproved later, although clinical trials are going on. In parallel, plasma therapy has been found fruitful in some extents too, and a number of vaccine trails are going on. This review article discussed the epidemiologic and mechanistic characteristics of SARS-CoV-2, and how drugs could act on this virus with the comparative discussion on progress and backwards of major drugs used till date, which might be beneficial for choosing therapies against COVID-19 in different countries.
