    While human beings are still facing the challenges of the pandemic coronavirus disease (COVID-19), a new viral disease, monkeypox raises concerns among healthcare authorities about this new threat. Since May 2022, thousands of people have been affected by a continuous monkeypox outbreak linked to close contact transmission in numbers of nonendemic nations. The Food and Drug Administration (FDA) has not yet approved any medications to treat monkeypox in humans. However, medications created for smallpox patients, such as antivirals and other medical countermeasures, might also be effective against monkeypox. Tecovirimat (TPOXX), brincidofovir, cidofovir antivirals and Vaccinia Immune Globulin Intravenous (VIGIV) are the medical countermeasures for the treatment of monkeypox. The second and third generations of smallpox vaccinations have been developed after many years of research. Some of these vaccines may also be beneficial for monkeypox. Three vaccinations, MVA-BN, LC16, or ACAM2000 can be used for monkeypox. Two of these (MVA-BN and LC16) have received approval for the purpose of preventing monkeypox. Considering the current vaccine shortage, widespread immunisation is not advised. Therefore, prevention is the best policy to keep everyone safe. The current review highlights the treatment available for the management of monkeypox. It also reviewed the preventive measures that human beings should take to protect themselves from monkeypox infection

    A new strain of the old pandemic, Monkeypox (MPX), has emerged with a more complicated clinical appearance. It is a source of relief that the fatality rate in the new monkeypox is lower, but communicability is higher. This infection’s diagnosis and therapy are still challenging and unknown. Researchers are reporting increased human-to-human transmission in the modified version of MPX. There have been several reports of the updated version of monkeypox in the European and American areas. Brazil, Colombia, France, Spain, Germany, Peru, the United Kingdom, and the United States of America have recorded over three thousand new cases of monkeypox through October 2022. Few antiviral medicines and vaccines are available on the market, making treatment of this condition difficult. MPX was previously declared an epidemic disease, but ignorance about it can bring devastation in the shape of the next pandemic-like COVID-19. This review aims to assess the virology, transmission, diagnosis, and therapy of MPX

    Background: Mumps virus (MuV) can trigger severe infections, such as parotitis, epididymo-orchitis, and meningitis. The effectiveness of MuV vaccine administration has been proven, but current outbreaks warrant the development of antivirals against MuV. Zingiber officinale var. Roscoe or ginger is often used as an alternative remedy. Currently, there are no known in vitro or in vivo studies that investigate ginger as an MuV antiviral. Purpose: This study aims to evaluate the antiviral potency of the bioactive compounds in Zingiber officinale var. Roscoe against MuV. Methods: Antiviral activity screening was conducted by druglikeness analysis, antiviral probability, molecular docking, and molecular dynamic simulation. Results: As an antiviral, 6-shogaol from Zingiber officinale var. Roscoe has potency against MuV. It has a good binding affinity and can establish interactions with the binding domain of the target protein by forming hydrogen, Van der Waals, and alkyl bonds. Conclusion: The complex of 6-shogaol_NP was predicted to be volatile but stable for triggering inhibitory activity. However, these results must be proved by in vivo and in vitro approaches to strengthen the scientific evidence

    Context: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has rapidly spread, causing a global pandemic with diverse symptoms and increased risk of mortality. Various symptoms and comorbidities contribute to a higher likelihood of death in patients. Additionally, existing antiviral drugs have shown incomplete efficacy. Rafflesia sp. and Sapria sp. are parasitic plants with potential medical applications as anti-SARS-CoV-2 agents. Aims: To evaluate the bioactive compounds derived from Rafflesia sp. and Sapria sp. as dual inhibitors against SARS-CoV-2. Methods: Ligand samples were obtained from the PubChem database. Target proteins essential for SARS-CoV-2 entry were obtained from the RCSB PDB. The antiviral potential of the bioactive compounds was evaluated using the Pass Online webserver. The bioactivity and inhibitory potential of selected ligands were analyzed using the SwissADME and Molinspiration web servers. In addition, a specific docking method was performed using PyRx software to determine binding activity and molecular interactions. Results: Computational analysis revealed that leucoanthocyanidin, ellagic acid, and catechin functioned as dual inhibitors, targeting angiotensin-converting enzyme 2 (ACE2), transmembrane protease serine 2 (TMPRSS2), furin, and cathepsin L for antiviral activity. However, valrubicin and diminazene, serving as control drugs for ACE2 and furin, respectively, demonstrated the most effective results through this mechanism. Further studies are required to validate these findings. Conclusions: The combination of bioactive compounds derived from Rafflesia sp. and Sapria sp. shows potential antiviral activity through a dual inhibitor mechanism involving leucoanthocyanidin, ellagic acid, and catechin, which target SARS-CoV-2 proteins, namely ACE2, TMPRSS2, furin, and cathepsin L

    Triple-negative breast cancer (TNBC) has been known as havoc among females globally. It is a heterogeneous group of cancer encompassing many breast cancers basically distinct by the lack of estrogen receptor, progesterone receptor, and overextension of the human epidermal growth factor receptor-2 gene. It can be caused by various factors, namely unbalanced diet, beverage consumption, smoking, hormonal imbalance, medication, genetic factor, and decreased levels of physical activity. It represents one of the most aggressive types of breast cancer, and researchers revealed that the chemical components of cardamom, namely limonene, cymene, pinene, linalool, borneol, cardamonin, indole-3-carbinol, and diindolylmethane, primarily target the programmed cell death lignin-1 gene of cancer which is more abundant in cancer cells than in healthy cells. There is no standard chemotherapy session for eradicating TNBC because targeted receptor absents in cancer cells as present in common breast cancer. Cardamonin has been identified as an effective component that targets most of the signaling pathways against TNBC. Metallic chelates of cardamonin with copper ion help to improve lipophilicity and bioavailability in cancer cells. The literature included in this review was assessed from the international databases, namely PubMed, Elsevier, Scopus, Google Scholar, Bentham, and Research Gate journals published between 2010 and 2023. Utilizing keywords for literature searching are breast cancer, triple negative breast cancer, cardamom, bioavailability, and cardamonin. A safe and efficient targeted therapy for this cancer has been difficult to develop due to its rapid proliferation and indefinite signaling pathway. Literature investigation enlightened that phytoconstituent reported in the cardamom reporting anticancer potential action against TNBC. Data concluded from this review can prove beneficial to the communal population in the treatment of TNBC and improve the health indicator in the future

    Many Asian countries use the bark of the Magnolia for medicinal purposes. Magnolia has many medical uses, including regulating GI motility, treating cough and asthma, preventing cardiovascular disease, and treating mental illness and brain disorders. To date, 118 magnolia species have been discovered. However, the International Union for Conservation of Nature has designated 231 species as vulnerable and critically endangered. Magnolia leaves yielded 20 isolated chemicals, including 16 lignans with 6 distinct structural types, such as honokiol, veraguensin, sitosterol, and magliflonenone. Magnolia species show pharmacological activities like Neuroprotective, anti-cancer, Anti-microbial, Antiplatelets, Anti-asthmatic, Gastrointestinal, and Hormone regulation. Magnolia bark extracts such as honokiol 2',6-di-(5-propenyl)-1,1'-biphenyl-2,2'-diol, have been demonstrated to benefit health. In recent in vitro and preclinical research, honokiol was found to have anti-inflammatory, anti-angiogenic, anti-oxidative, and anti-cancer activities. Honokiol and magnolol prevented the thromboxane B2 synthesis in response to thrombin, arachidonic acid, and collagen. So, soon, if we cultivate and save the endangered magnolia species through biotechnological means, it will be a boon for mankind

    Aflatoxin-B1 (AFB1) is a common contaminant for staple foods during the storage process. Chronic exposure to AFB1 is widely known to induce the development of hepatocellular carcinoma (HCC). However, there is a lack of understanding of AFBi role in HCC mechanism. This research aims to identify protein(s) in HCC that might interact with AFB1 and to predict the pathway effected by AFB1. Analyses were performed using bioinformatics tools. SMILES notation of AFB1 was submitted into Swiss Target Prediction. Interaction among predicted proteins were analyzed by using STRING. The 3D structure of target protein was constructed by homology modeling. Reverse docking was performed, and the result was ranked based on binding affinity score. Furthermore, protein interaction network was constructed and analyzed by using Cytoscape. Results showed that three protein groups were predicted as target of AFB1, such as kinases, phosphatases, and G protein-coupled receptor with probability of 46.7%, 20%, and 6.7%, respectively. Seven proteins of kinases were strongly related to HCC, including RAF1, MAPK1, MAPK3, AKT1, EGFR, GSK3B, and mTOR. Reverse docking considered the AKT1-AFB1 as the most potential complex with the lowest affinity score -10.2 kcal.mol-1. It has hydrophobic bonds in Trp80, Val270, Tyr272, Asp292, Thr211, Leu210, Leu264, and Lys268 residues, whereas hydrogen bond in Ser205 residues. Moreover, further analysis demonstrated that interaction of AKT1-AFB1 is related to the metastasis pathway in HCC mechanism
