The second largest cause of cancer-related death worldwide, Hepatocellular Carcinoma (HCC) is also the most common primary liver cancer. HCC typically arises in patients with liver cirrhosis. Existing synthetic medicines for treating chronic liver disease are ineffective and come with undesirable side effects. Although herbal remedies have widespread popularity, there is still a long road ahead before they are fully accepted by the scientific community. Secondary metabolites and phytochemicals found in plants are abundant in both the human diet and the non-human environment. Natural plant chemicals have been shown to be beneficial as therapeutic and chemopreventive treatments for a wide variety of chronic disorders. Many diseases, including HCC, can be effectively treated with the help of phytochemicals found in food. Resveratrol, curcumin, urolithin A, silibinin, quercetin, N-trans-feruloyl octopamine, emodin, lycopene, caffeine, and phloretin are all examples. Approximately, 60% of all anticancer medications are determined to be derived from natural substances, according to recent studies. Plant derivatives have played an important role in cancer due to their capacity to scavenge free radicals, limit cell proliferation, and set off apoptosis. The progression of HCC is linked to inflammatory signaling pathways, and this study sought to look at how novel approaches, such as phytomedicines, are being used to fight cancer. Recent advancements in molecular mechanisms and drug targeting for HCC have been discussed in this review.

The family of proteins known as Bromodomain and Extra-Terminal (BET) proteins has become a key participant in the control of gene expression, having a significant impact on numerous physiological and pathological mechanisms. This review offers a thorough investigation of the BET protein family, clarifying its various roles in essential cellular processes and its connection to a variety of illnesses, from inflammatory disorders to cancer. The article explores the structural and functional features of BET proteins, emphasizing their special bromodomain modules that control chromatin dynamics by identifying acetylated histones. BET proteins' complex roles in the development of cardiovascular, neurodegenerative, and cancer diseases are carefully investigated, providing insight into possible treatment avenues. In addition, the review carefully examines the history and relevance of BET inhibitors, demonstrating their capacity to modify gene expression profiles and specifically target BET proteins. The encouraging outcomes of preclinical and clinical research highlight BET inhibitors' therapeutic potential across a range of disease contexts. The article summarizes the state of BET inhibitors today and makes predictions about the challenges and future directions of the field. This article provides insights into the changing field of BET protein-targeted interventions by discussing the potential of personalized medicine and combination therapies involving BET inhibitors. This thorough analysis combines many aspects of BET proteins, such as their physiological roles and their roles in pathophysiological conditions. As such, it is an invaluable tool for scientists and medical professionals who are trying to figure out how to treat patients by using this fascinating protein family.

Background: Nitazoxanide not only exhibits a broad spectrum of activities against various pathogens infecting animals and humans but also induces cellular autophagy. Currently, the pattern of action and subcellular targets of nitazoxanide-induced cellular autophagy are still unclear.

Methods: To identify potential targets of nitazoxanide in mammalian cells, we developed an af-finity chromatography system using tizoxanide, a deacetyl derivative of nitazoxanide, as a ligand. Affinity chromatography was performed using VERO cell extracts on tizoxanide-biotin, and the isolated binding proteins were identified by mass spectrometry. Candidate target proteins ob-tained using affinity chromatography were co-analysed with the drug affinity response target sta-bility method. Fluorescent probes obtained by coupling rhodamine B to nitazoxanide were used for intracellular localisation of the binding targets. Solvent-induced protein precipitation profiling and thermal proteome profiling were used to further validate the binding proteins.

Results: The joint analysis of the drug affinity response target stability method and affinity chro-matography resulted in the screening of six possible candidate target proteins. Fluorescent probes localised the nitazoxanide-binding protein around the nuclear membrane. Molecular docking re-vealed that the binding proteins mainly formed hydrogen bonds with the nitro group of nitazoxa-nide. Solvent-induced protein precipitation profiling and thermal proteome profiling further vali-dated SEC61A, PSMD12, and PRKAG1 as potential target proteins of nitazoxanide.

Conclusion: The data supports the idea that nitazoxanide is a multifunctional compound with multiple targets.

An important sensation that warns of potential harm to a specific area of the body is pain. The prevalence of pain-related conditions globally is a significant and growing public health issue. Chronic pain affects an estimated 1.5 billion people worldwide, with prevalence rates varying by region and demographic factors. Along with diabetes, cardiovascular disease, and cancer, pain is among the most frequent medical diseases. Opioid analgesics are the mainstay of current pain therapies, which are ineffective. Opioid addiction and its potentially fatal side effects necessitate novel treatment strategies. Nanotechnology offers potential advantages in pain management by enabling targeted drug delivery, which can enhance the efficacy and reduce the side effects of analgesic medications. Additionally, nanoparticles can be designed to release drugs in a controlled manner, improving pain relief duration and consistency. This approach also allows for the delivery of therapeutics across biological barriers, potentially enhancing treatment outcomes for chronic pain conditions. Nanomedicine enables sensitive and focused treatments with fewer side effects than existing clinical pain medicines; it is worth exploring as a potential solution to these problems. Furthermore, medication delivery systems that use nanomaterials are being used to treat pain. Whether it's the distribution of a single medication or a combination of therapies, this review seeks to summarise the ways in which drug delivery systems based on nanomaterials can be utilised to successfully treat and alleviate pain. For the purpose of writing this paper, we consulted several online libraries, including Pubmed, Science Direct, Pubmed Prime, and the Cochrane Library, to gather fresh and up-to-date material. This overview delves into the ins and outs of pain's pathophysiology, the present state of pain treatment, potential new pain treatment targets, and the various initiatives that have been launched and are still in the works to address pain with nanotechnology. Recent developments in nanomaterials-based scavenging, gene therapy for pain aetiology, and nanoparticle-based medicine delivery for side effect reduction are highlighted. Analgesics have been further covered in our discussion on FDA-approved pharmaceuticals and clinical advancements.

Diabetes is a metabolic disorder caused by high glucose levels, leading to serious threats such as diabetic neuropathy and cardiovascular diseases. One of the most reliable measures for controlling postprandial hyperglycemia is to reduce the glucose level by inhibiting enzymes in the digestive system, such as Alpha-Glucosidase and Alpha-Amylase. Here, we have investigated the use of inhibitors to inhibit carbohydrate metabolism in order to restrict glucose levels in diabetic patients. Acarbose, Voglibose, and Miglitol are three inhibitors approved by the FDA that efficiently inhibit these two enzymes and thereby minimising hyperglycemia but are al-so significantly helpful in reducing the risk of cardiovascular effects. We also provide insight into the other known inhibitors currently available in the market. The adverse effects associated with other inhibitors emphasise the demand for the latest in silico screening and in vitro validation in the development of potent inhibitors with greater efficacy and safety for the treatment of Type 2 diabetes. The recent findings suggest that Alpha-Glucosidase and Alpha-Amylase play a major role in carbohydrate metabolism and triggering the increase in glucose levels. This review pro-vides the latest scientific literature findings related to these two enzymes as well as the role of primary and secondary inhibitors as potential candidates. Moreover, this review elaborates the framework on the mechanism of action, different plant sources of extraction of these enzymes, as well as kinetic assay of inhibitors and their interaction that can be used in future prospects to de-velop potential leads to combat Type 2 diabetes.
