Article Synopsis
  • The increasing issue of multidrug resistance (MDR) in pathogenic bacteria like Staphylococcus aureus has prompted the search for new treatment methods, including FDA-drug repurposing.
  • Ambroxol was tested against clinical MDR S. aureus isolates and showed effective antibacterial activity, with concentrations needed to inhibit growth between 0.75 to 1.5 mg/mL, and also disrupted biofilm formation in about 42% of the isolates.
  • In vivo studies demonstrated ambroxol's ability to enhance skin tissue healing in S. aureus infected burn injuries by reducing bacterial presence and inflammation, with further investigations suggesting its action may involve binding to several targets in the bacterium.

Ethnopharmacological Relevance: Inflammation is a biological process in response to injury, resulting in altered blood flow, increased vascular permeability, tissue destruction, and the production of reactive oxygen species (ROS) and inflammatory mediators. Zygophyllum simplex L., a medicinal plant traditionally used in the Arabian Peninsula for inflammatory disorders, has demonstrated promising in vitro anti-inflammatory activity due to its phenolic content.

Hesperidin (Hes) functions as a strong antioxidant and anti-inflammatory to guard against damage to the heart, liver, and kidneys. Nevertheless, due to its restricted solubility and bioavailability, a delivery method is required for it to reach a specific organ. In this study, ion gelation was used to synthesize a chitosan/hesperidin nanoformulation.

Cancer stem cells (CSCs) are cancer cells that can self-renew and give rise to tumors. The multipotency of CSCs enables the generation of diverse cancer cell types and their potential for differentiation and resilience against chemotherapy and radiation. Additionally, specific biomarkers have been identified for them, such as CD24, CD34, CD44, CD47, CD90, and CD133.

This study uses the aerial parts of total extract (PMTE) to synthesize silver nanoparticles (AgNPs) in an environmentally friendly manner. TEM, SEM, FTIR, X-ray powder diffraction (XRD), Zeta potential, UV, and FTIR were used to characterize the green silver nanoparticles (PM-AgNPs). PM-AgNPs were evaluated as anticancer agents compared to (PMTE) against breast (MCF-7), lung (A549), and ovary adenocarcinoma (SKOV3) human tumour cells.

The vast dissemination of resistance to different antibiotics among bacterial pathogens, especially foodborne pathogens, has drawn major research attention. Thus, many attempts have been made to reveal novel alternatives to the current antibiotics. Due to their variable pharmacologically active phytochemicals, plants represent a good solution for this issue.

The increasing rates of morbidity and mortality owing to bacterial infections, particularly have necessitated finding solutions to face this issue. Thus, we elucidated the phytochemical constituents and antibacterial potential of extract (CDE). Using LC-ESI-MS/MS, the main phytoconstituents of CDE were explored, which were kaempferol-3,7--bis-alpha-L-rhamnoside, isorhamnetin, cyanidin-3-glucoside, kaempferide, kaempferol-3--alpha-L-rhamnoside, caffeic acid, isoquercitrin, quinic acid, isocitrate, mannitol, apigenin, acacetin, and naringenin.

The widespread dissemination of bacterial resistance has led to great attention being paid to finding substitutes for traditionally used antibiotics. Plants are rich in various phytochemicals that could be used as antibacterial therapies. Here, we elucidate the phytochemical profile of ethanol extract (EMEE) and then elucidate the antibacterial potential of ECEE against clinical isolates.

Objective: Both humoral and cellular immunity can be significantly influenced by the immunological responses to vaccination, and both responses are essential. Vaccination is the most consistent, safe, and cost-efficient practice for controlling the COVID-19 pandemic.

Patients And Methods: Blood samples were collected from participants who received two vaccine doses of COVID-19 Pfizer/BioNTech (BNT162b2) before and on days 7 and 10 after the first and second immunization.

This study investigated the antioxidant, anticancer, antibacterial properties of Dioon rzedowskii extract, which had not been previously explored. We aimed to determine the extract's effect on liver and breast cancer cell lines and on solid Ehrlich carcinoma (SEC) mouse model to investigate the underlying molecular mechanisms. Three female albino mice groups were established: a tumor control group, a group treated with 100 mg/kg of the extract (D100), and a group treated with 200 mg/kg of the extract (D200) for 16 days after tumor development.

Parkinson's disease (PD) is a progressive neurodegenerative disease as a result of the degeneration of dopaminergic neurons in the substantia nigra pars compacta (SNpc). The fundamental features of PD are motor and non-motor symptoms. PD symptoms develop due to the disruption of dopaminergic neurotransmitters and other neurotransmitters such as γ-aminobutyric acid (GABA).

Triple-negative breast cancer (TNBC) comprises 10 % to 20 % of breast cancer, however, it is more dangerous than other types of breast cancer, because it lacks druggable targets, such as the estrogen receptors (ER) and the progesterone receptor (PR), and has under expressed receptor tyrosine kinase, ErbB2. Present targeted therapies are not very effective and other choices include invasive procedures like surgery or less invasive ones like radiotherapy and chemotherapy. This study investigated the potential anticancer activity of some novel quinazolinone derivatives that were designed on the structural framework of two approved anticancer drugs, Ispinesib (KSP inhibitor) and Idelalisib (PI3Kδ inhibitor), to find out solutions for TNBC.

Multiple sclerosis (MS) is the most frequent inflammatory and demyelinating disease of the central nervous system (CNS). The underlying pathophysiology of MS is the destruction of myelin sheath by immune cells. The formation of myelin plaques, inflammation, and injury of neuronal myelin sheath characterizes its neuropathology.
