Summary: In this study, a library of 19 analogues of Vorinostat was developed and tested for their HDAC inhibition and cytotoxic effects on cancer and normal cell lines. Three compounds based on dibenzo[b,f]azocin-6(5H)-one, 11,12-dihydrodibenzo[b,f]azocin-6(5H)-one, and benzo[b]naphtho[2,3-f][1,5]diazocine-6,14(5H,13H)-dione scaffolds showed better HDAC inhibition and lower IC50 values in leukemic and lymphoma cell lines compared to Vorinostat. These compounds exhibited higher activity and selectivity against specific cancer cell lines and a correlation between HDAC inhibition and cytotoxic effects was observed.

Summary: This study identifies hydroxamic acid as a potent inhibitor of tyrosinase by interacting with dicopper atoms. Hydroxamate-containing molecules, including anticancer drugs targeting histone deacetylase, have been found to significantly inhibit tyrosinase activity. Experiments with cell lysates confirm the inhibitory effects of these inhibitors on mammalian tyrosinase. Docking simulation data reveal the molecular interactions between hydroxamate-containing molecules and tyrosinase.

Summary: This study reveals a novel mechanism by which histone deacetylase inhibitors suppress basal-like breast cancer (BLBC) by promoting proteasomal degradation of KLF5 protein through ubiquitination. The acetylation of KLF5 at lysine 369 decreases its binding with deubiquitinase BAP1, leading to decreased BLBC cell viability and proliferation.

Our findings showed that compounds 7 e-f were the most active HDAC inhibitors and had good anticancer activity. Docking assays revealed the binding mode and selectivity of compound 7 f towards 8 HDAC isoforms.

Summary: In recent years, histone deacetylases (HDACs) have been identified as promising targets for cancer treatment. The use of HDAC inhibitors (HDACis) to inhibit HDACs has shown great potential. Various types of HDACis, such as hydroxamic acids, benzamides, thiols, short-chain fatty acids, and cyclic peptides, are classified based on their chemical structures. The introduction of fluorine into the chemical structure of HDACis can increase potency and selectivity towards specific isoforms of HDACs. However, the impact of fluorination is not always clear and can affect lipophilicity, solubility, and permeability, thus influencing the potency. The addition of fluorine is also commonly used for labeling purposes in the investigation of newly synthesized fluorine-containing active compounds.

Summary: This paper investigates the bioaccumulation of vanadium and its correlation with cellular and molecular developmental pathways in sea urchin embryos. The results indicate that vanadium accumulation interferes with calcium uptake and disrupts biomineralization during sea urchin development. Moreover, vanadium is found to modulate cell signaling pathways and activate cell-selective apoptosis. This study highlights the suitability of sea urchin embryos as an experimental model for studying metal-related cellular and molecular responses.

Summary: This study investigated the effects of vanadium on sea urchin embryo development and proteolytic activity of gelatinases. The results showed that vanadium exposure caused morphological aberrations, reduced embryonic cell distribution, and altered embryo volume. Additionally, vanadium affected the expression and activity of gelatinases, particularly MMP-14. These findings suggest that an integrated approach combining morphology, proteolytic activity, and MMP-14 expression is important for studying the effects of vanadium.
