Tolclofos-methyl
Based on 1 Customer Validation
Tolclofos-methyl is an organophosphorus fungicide. Tolclofos-methyl undergoes photoinduced oxidative degradation to form oxo-analog derivatives. Tolclofos-methyl inhibits spore division in fungi and oomycetes, induces cytoplasmic leakage, and interferes with flagellar movement. Tolclofos-methyl is rapidly metabolized and excreted in rodents. Tolclofos-methyl can be used in studies related to fungal infections.

Biological Activity
Tolclofos-methyl undergoes rapid photoinduced oxidation on kaolinite clay mineral films; biphasic photoinduced oxidation occurs on montmorillonite mineral films; this photoinduced oxidation is delayed by dehydration of the kaolinite and montmorillonite clay mineral films and the removal of molecular oxygen[1].
Tolclofos-methyl completely inhibits mycelial growth of Rhizoctonia solani, Corticium rolfsii, and Typhula incarnata[2].
Tolclofos-methyl (4 μg/mL; up to 26 hours) completely inhibits sporidial multiplication, alters cellular morphology, and causes cytoplasmic loss in Ustilago maydis sporidia after 26 hours, while allowing partial dry weight increase for several hours[2].
Tolclofos-methyl (1.9-100 μg/mL) inhibits Botrytis cinerea mycelial growth[2].
Tolclofos-methyl (20 μg/mL; 24 hours) causes cytoplasmic leakage via cell bursting in some Botrytis cinerea germinating conidia[2].
Tolclofos-methyl (4-8 μg/mL) rapidly inhibits swimming, induces abnormal flagella movement, triggers encystment, and causes cystospore bursting in Phytophthora capsici zoospores[2].
Tolclofos-methyl (4-8 μg/mL) inhibits swimming, induces circular movement (in Pseudoperonospora cubensis), triggers encystment, and causes cystospore bursting in zoospores of Pseudoperonospora cubensis, Phytophthora infestans, and Plasmopara viticola[2].

14C-Tolclofos-methyl (5-50 mg/kg; p.o.; single dose) results in 87.3-90.9% excretion of radiocarbon within 7 days, less than 1% whole-body residue at 7 days with 3,5-dichloro-4-hydroxybenzoic acid and its glycine conjugate as major metabolites in ICR mice[3].

Animal Model:Sprague-Dawley (male: 5-week-old, ~190 g; female: 5-week-old, ~140 g)[3]
-
Dosage:5 mg/kg
-
Administration:p.o.; single dose
-
Result:Excreted over 87% of radiocarbon via urine, feces and expired air within 7 days, with urine as the primary excretion route.
Retained less than 1% of radioactive substances in the whole body at day 7.
Produced low tissue residues in most tissues, and relatively high residues were detected in hair.
Displayed prominent radioactivity in digestive organs, liver and kidney at early stages, and the radioactivity declined sharply at 24 hours.
Identified 14 metabolites in excreta, and 3,5-dichloro-4-hydroxybenzoic acid was the predominant component.

Animal Model:ICR (male: 7-week-old, ~28 g; female: 7-week-old, ~24 g)[3]
-
Dosage:5 mg/kg; 50 mg/kg (for metabolite isolation in male mice)
-
Administration:p.o.; single dose
-
Result:Excreted most radiocarbon via urine, feces and expired air within 7 days, and urine was the major excretion pathway.
Retained less than 1% of the total radioactive dose in the body at day 7.
Detected at least 13 metabolites in excreta.
3,5-dichloro-4-hydroxybenzoic acid and its glycine conjugate were the predominant metabolites.
