Thiophanate-Methyl exhibits a broad range of bioactivities, including notable antifungal, antiviral, and enzyme-inhibitory properties. It demonstrates substantial antifungal activity against a variety of pathogens, such as Colletotrichum fragariae, Fusarium oxysporum, Pestalotiopsis microspora, and Thanatephorus cucumeris, with significant inhibitory effects on mycelial growth, conidium germination, and disease control in plants. Specifically, it inhibits mycelial growth with Minimum Inhibitory Concentration (MIC) values of 4000.0 ppm for Cochliobolus pallescens, Fusarium oxysporum, and Glomerella tucumanensis, and shows an EC50 as low as 10.84 ug/mL against Rhizoctonia solani AG-1 IA and 1.03 ug/mL against Botryotinia fuckeliana.
In addition to its antifungal properties, Thiophanate-Methyl has antiviral activity against SARS-CoV-2, inhibiting cytotoxicity in Caco-2 and VERO-6 cells at a concentration of 10 uM and demonstrating -3.43% and 0.14% inhibition respectively. It also inhibits the SARS-CoV-2 3CL-Pro protease by 11.73% at 20 µM.
Enzyme inhibition studies reveal that Thiophanate-Methyl is a potent inhibitor of various enzymes including HSD17B4, ALDH1A1, and Bacillus subtilis Sfp PPTase, with potencies ranging from 316.2 nM to 50118.7 nM. It also inhibits human FAAH at 1 uM with an 8.37% inhibition rate, and HDAC6 enzyme with mixed results depending on the substrate used.
Overall, Thiophanate-Methyl displays a diverse spectrum of biological activities, making it a promising candidate for further research in antifungal therapy, antiviral treatment, and enzyme inhibition applications..
