Article Synopsis
  • * The article explores the synthesis of bis-thiazole derivatives as potential antiviral candidates against Coxsackievirus B, focusing on one particularly effective derivative, 7a, which inhibits both viral adsorption and replication.
  • * Molecular docking studies revealed that several compounds effectively bind to significant Cox B virus proteins, suggesting their ability to inhibit viral enzyme activity, while an ADMET study indicates these compounds meet favorable physicochemical criteria for drug development.

Background And Objective: Breast cancer is the most common form of cancer in women and is the leading cause of cancer-related deaths among women globally. In this study, we aimed to synthesize a series of tropane derivatives to investigate their Hsp90 inhibitory activity as well as their cytotoxic impact on breast cancer cells (MCF- 7 and MDA-MB-231).

Methods: Novel fused-tropane derivatives were created and produced as inhibitors of Hsp90, taking inspiration from XL888, a tropane medication used for treating cancer.

Silks are a class of proteins generated naturally by different arthropods, including silkworms, spiders, scorpions, mites, wasps, and bees. This review discusses the silk fibroin and silk sericin fabricated by Bombyx mori silkworm as versatile fibers. This silk fiber is predominantly composed of hydrophobic silk fibroin and hydrophilic silk sericin.

Article Synopsis
  • * The results indicated higher concentrations of heavy metals (like Fe, Cu, Zn, Mn, and Ni) in fish compared to water, particularly in Lake Brullus, which was identified as the most polluted site, while Lake Nasser showed the least contamination.
  • * Gender-specific responses to heavy metal exposure were observed, with males showing increased expression of antioxidant and inflammatory-related genes, while females had elevated immune-related gene expression; growth-related genes were generally downregulated in more polluted sites, contrasting with normal patterns in Lake Nasser.

Article Synopsis
  • The study explores how transcription factors (TFs) recognize specific DNA sequences, shapes, and flexibilities, which are essential for organism development.
  • The research focuses on 28 key TFs and reveals that they have unique preferences for the composition and structural properties of DNA near their binding sites.
  • The findings suggest that while some cofactors have similar binding preferences and are found close together, others with different preferences tend to bind farther apart, enhancing our understanding of TF interactions and transcriptional regulation.

New derivatives of tropane scaffold were prepared from the reaction of their thione or thioamide derivatives with α-halocarbonyl compounds. The structures of all new derivatives were assured and proved with their spectral data. The novel tropane derivatives were examined for their cytotoxicity on two colon tumor cell lines; Caco2 and HCT116 cells.

Introduction Uterine fibroids and breast fibroadenomas are common female benign neoplasms that are similarly derived from a single clonal origin and are modulated by estradiol concentration in blood. However, the association between these neoplasms has not yet been explored. Hence, this study aims to investigate the relationship between uterine fibroids and breast fibroadenomas.

Viral infections of the central nervous system (CNS) are common worldwide and result in considerable morbidity and mortality associated with neurologic illness. Until now, there have been no epidemiologic data regarding viruses causing aseptic meningitis, encephalitis, and CNS infections in Egypt. We investigated 1735 archived cerebrospinal fluid samples collected from Egyptian patients between 2016 and 2019 and performed molecular characterization for infection for12 different viruses: herpes simplex viruses 1 and 2 (HSV-1 and HSV-2), varicella-zoster virus (VZV), Epstein-Barr virus (EBV), cytomegalovirus (CMV), human herpesviruses 6 and 7 (HHV-6 and HHV-7), human enteroviruses (HEVs), human parechovirus (HPeV), parvovirus B19 (B19V), adenovirus (AdV), and mumps virus (MuV).

Background: The new immunotherapies have not only changed the oncological therapeutic approach but have also made it necessary to develop new imaging methods for assessing the response to treatment. Delta radiomics consists of the analysis of radiomic features variation between different medical images, usually before and after therapy.

Purpose: This review aims to evaluate the role of delta radiomics in the immunotherapy response assessment.

, the causative agent of tuberculosis, has evolved over time into a multidrug resistance strain that poses a serious global pandemic health threat. The ability to survive and remain dormant within the host macrophage relies on multiple transcription factors contributing to virulence. To date, very limited structural insights from crystallographic and NMR studies are available for TFs and TF-DNA binding events.

With the aim of developing cyclin-dependent kinase 2 (CDK2) inhibitors with strong antibreast cancer efficacy, new tricyclic and tetracyclic benzo[6,7]cycloheptane derivatives were synthesized. The newly synthesized tri- and tetracyclic derivatives were achieved from the reaction of 4-(4-morpholin-4-yl-phenyl)-1,3,4,5,6,7-hexahydro-benzo[6,7]cyclohepta[1,2-d]pyrimidine-2-thione (5) with α-haloketone derivatives as hydrazonyl chlorides, phenacyl bromide derivatives, chloroacetone, and ethyl substituted acetate derivatives. The MCF-7 and MDA-MB-231 breast cancer cell lines were utilized to examine the anticancer properties.
