Spired by the chemical structure of Cilostazol, a selective phosphodiesterase 3A (PDE3A) inhibitor, several novel hybrid compounds of nucleobases (uracil, 6-azauracil, 2-thiuracil, adenine, guanine, theophylline and theobromine) and tetrazole were designed and successfully synthesized and their inhibitory effects on PDE3A as well as their cytotoxicity on HeLa and MCF-7 cancerous cell lines were studied. Obtained results show the linear correlation between the inhibitory effect of synthesized compounds and their cytotoxicity. In some cases, the PDE3A inhibitory effects of synthesized compounds are higher than the Cilostazol. Besides, compared to a standard anticancer drug methotrexate, some of the synthesized compounds showed the higher cytotoxicity against the HeLa and MCF-7 cancerous cell lines.

Previous studies on natural samples of pampaloite (AuSbTe) revealed the crystal structure of a potentially cleavable and/or exfoliable material, while studies on natural and synthetic montbrayite (Sb-containing AuTe) claimed various chemical compositions for this low-symmetry compound. Few investigations of synthetic samples have been reported for both materials, leaving much of their chemical, thermal, and electronic characteristics unknown. Here, we investigate the stability, electronic properties, and synthesis of the gold antimony tellurides AuSbTe and AuSbTe (montbrayite).

Acrolein (ACR) present in vivo and in vitro can damage proteins and DNA, linking it to various chronic diseases. In this paper, ergothioneine (EGT), abundant in edible mushrooms, has been studied for its ability to trap ACR and its reaction pathway with ACR at high temperatures using ultraperformance liquid chromatography-mass spectrometry (UPLC-MS/MS). We synthesized the adducts (EGT-ACR-1 and EGT-ACR-2), elucidating their structure and reaction site through HRMS and nuclear magnetic resonance.

ConspectusThe advancement of synthetic methodologies is fundamentally driven by a deeper understanding of the structure-reactivity relationships of reactive key intermediates. Carbyne anions are compounds featuring a monovalent anionic carbon possessing four nonbonding valence electrons, which were historically confined to theoretical constructs or observed solely within the environment of gas-phase studies. These species possess potential for applications across diverse domains of synthetic chemistry and ancillary fields.

During batch fermentation, a variety of compounds are synthesized, as microorganisms undergo distinct growth phases: lag, exponential, growth-no-growth transition, stationary, and decay. A detailed understanding of the metabolic pathways involved in these phases is crucial for optimizing the production of target compounds. Dynamic flux balance analysis (dFBA) offers insight into the dynamics of metabolic pathways.
