Abstract
Purpose of ReviewThis article provides a brief overview of electrochemical potential-biological activity relationships of natural and synthetic cyclic sulfur-containing molecules against Steinernema feltiae, Botrytis cinerea, and Neuro 2a cell line (from murine neuroblastoma).Recent FindingsThis article finds natural cyclic sulfur-containing molecules and their synthetic analogues were more reducing than glutathione (GSH) and therefore apparently did not react with GSH. The nematicidal assay indicated that cyclic disulfide compound of 1 (3-vinyl-4H-1,2-dithiin, 1,2-VDT) was more active against Steinernema feltiae with the LD50 value 151.93 ± 1.3 μM, while dithiole thione group compounds showed moderate activity against this nematode. The article also finds compound 7 (3H-1,2-dithiole-3-thione or dithiolethione, DT) has a strong activity against all different strains of Botrytis cinerea in the range concentration of 0.1–0.5 mM. This article also finds that compounds 3 (1,2-dithiane, 1,2-DT), 4 (1,5-dithiacyclooctane, 1,5-DTCO), and 7 (3H-1,2-dithiole-3-thione or dithiolethione, DT) possess some moderate activity on Neuro 2a cell lines.SummaryAntinematode, antifungal, and anticancer activity of cyclic sulfur-containing molecules indicated that they could be promising candidates for “green pesticides” or phytoprotectans and for cancer prevention.
