Chitin synthase inhibitor 4 (compound 4fh) is a chitin synthase inhibitor with fungicidal effect. Chitin synthase inhibitor 4 is a potential chitin synthase-based fungicide in agriculture[1].
Chitin synthase inhibitor 4 shows good antifungal activities against V. mali and S. sclerotiorum with EC50 values of 0.71 and 2.47 μg/mL, respectively[1].
Chitin synthase inhibitor 4 (50 μg/mL) displays potency inhibition against V. mali and S. sclerotiorum with inhibition rates of 90.3% and 88.7%, respectively[1].
Chitin synthase inhibitor 4 (1 μg/mL) blocks the phae growth, results abnormal growth, with inducing cell content decreasing, cell wall degradation, and plasmolysis[1].
Chitin synthase inhibitor 4 (50 μM; 3 h) exhibits inhibition against chitin synthase and polyoxin D with inhibition rates of 68.08% and 63.84%, respectively[1].
Chitin synthase inhibitor 4 (50 μg/mL) has considerable curative and protective effects against S. sclerotiorum vivo, and no obvious ptotoxicity [1].
Chitin synthase inhibitor 4 has low acute toxicity, with no carcinogenic and mutagenic toxicity risk[1].
