AI Article Synopsis
Article Abstract
A structure-activity relationship study on polyamine derivatives led to the synthesis and the determination of antikinetoplastid activity of 17 compounds. Among them, a spermidine derivative (compound 13) was specifically active in vitro against Leishmania donovani axenic amastigotes (IC50 at 5.4μM; Selectivity Index >18.5) and a spermine derivative (compound 28) specifically active against Trypanosoma brucei gambiense (IC50 at 1.9μM; Selectivity Index >52).

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.
