Novel Endocytosis Inhibitors Block Entry of HIV-1 Tat into Neural Cells.

Many pathogens including viruses enter cells by endocytosis. We identified and evaluated novel endocytosis inhibitors capable of blocking the entry of the HIV-1 Tat protein into neuronal cells and investigated their potential protective properties against Tat-induced neurotoxicity. In this study, the compounds Les-6631 and Les-6633 were synthesized and assessed.

Selected Markers of Inflammation in the Saliva of Children Infected with .

has been of interest to scientists and clinicians for many years, often causing diagnostic difficulties, especially in the youngest age group, in children. The presence of this bacterium in the population depends on the geographic region. However, it is assumed that even half of the world's population may be infected with .

Trastuzumab Potentiates Antitumor Activity of Thiopyrano[2,3-]Thiazole Derivative in AGS Gastric Cancer Cells.

Gastric cancer remains a significant therapeutic challenge, highlighting the need for new strategies to improve treatment efficacy. This study investigates the potential of combined therapy with the novel Thiopyrano[2,3-]Thiazole derivative LES-6400 and the anti-HER2 antibody trastuzumab in AGS gastric cancer cells. The antitumor effects of the combined therapy were evaluated using various techniques, including the MTT assay for cell viability, [H]-thymidine incorporation for DNA synthesis, and flow cytometry to assess apoptosis (Annexin V-FITC/PI staining), mitochondrial membrane potential (MMP), and inflammatory cytokine levels.

The Anticancer Potential of Edible Mushrooms: A Review of Selected Species from Roztocze, Poland.

Edible mushrooms are not only a valued culinary ingredient but also have several potential medicinal and industrial applications. They are a rich source of protein, fiber, vitamins, minerals, and bioactive compounds such as polysaccharides and terpenoids, and thus have the capacity to support human health. Some species have been shown to have antioxidant, anti-inflammatory, anticancer, and immunomodulatory properties.

The Proapoptotic Action of Pyrrolidinedione-Thiazolidinone Hybrids towards Human Breast Carcinoma Cells Does Not Depend on Their Genotype.

The development of new, effective agents for the treatment of breast cancer remains a high-priority task in oncology. A strategy of treatment for this pathology depends significantly on the genotype and phenotype of human breast cancer cells. We aimed to investigate the antitumor activity of new pyrrolidinedione-thiazolidinone hybrid molecules , , and towards different types of human breast cancer cells of MDA-MB-231, MCF-7, T-47D, and HCC1954 lines and murine breast cancer 4T1 cells by using the MTT, clonogenic and [H]-Thymidine incorporation assays, flow cytometry, ELISA, and qPCR.
