Bitertanol

Описание

Bitertanol is a broad-spectrum triazole fungicide that is active against a variety of fungi, including V. inaequalis and V. pirina, which are responsible for apple and pear scab, respectively, as well as S. mors-uvae and P. ribis, which are responsible for American gooseberry mildew and leaf spot in black currants, respectively. It is active against isolates of V. inaequalis (MICs = 0.6 and 1 μg/ml) but repeated use leads to resistance and cross-resistance (MICs = 9.8-13 μg/ml for bitertanol-resistant isolates). Bitertanol inhibits the cytochrome P450 (CYP450) isoform CYP3A4 (IC₅₀ = 2.74 μM) and inhibits androgenic activity induced by the androgen receptor agonist DHT in a yeast two-hybrid assay (IC₅₀ = 79.85 μM). In rats, bitertanol (10-300 mg/kg, i.p.) increases operant responding on one- and five-minute fixed interval schedules with no effect on motor activity.

Метаболический путь

Bitertanol is a mixture of two diastereoisomeric pairs and this complicates its metabolism, each biotransfonnation affording a mixture of isomers. Metabolism has been studied under environmental conditions and in plants and mammals. Degradation in soil and sediments is slow and only small quantities of products (other than CO₂ and bound residues) are produced. Most information is available for mammals in which metabolism occurs mainly by oxidative routes followed by conjugation. The information presented below is derived from the UK MAFF Pesticide Safety Directorate (PSD, 1994).
