Zoxamide
Based on 1 Customer Validation
Zoxamide (RH-7281) is an oomycete Fungicide and covalent β-tubulin inhibitor. RH-7281 inhibits the assembly of tubulin into microtubules in vitro. Zoxamide binds covalently to β-tubulin, disrupting microtubule assembly and the cytoskeleton. Zoxamide blocks nuclear division in germinated hyphae of Phytophthora capsici and inhibits hyphal growth of Phytophthora capsici.

Biological Activity
Studies show that all field-collected isolates of Phytophthora cactorum are sensitive to zoxamide (0.02-1.0 mg/L; 6 days), with a mean EC50 value of 0.14 mg/L for inhibiting radial mycelial growth[1].
Zoxamide (0-1 ppm) rapidly and potently inhibits nuclear division in Phytophthora capsici seedlings[2].
Zoxamide (0.05 ppm; 30 min) completely disrupts the microtubule cytoskeleton in germ tubes of *Phytophthora capsici*, eliminating detectable microtubule filaments[2].
Zoxamide (5-30 μM; 1-8 h) inhibits in vitro microtubule assembly of tubulin isolated from bovine brain in a dose-dependent manner, and its inhibitory potency increases with prolonged pre-incubation time[2].
Zoxamide (16 h) potently inhibits the mycelial growth of *Phytophthora capsici* in microtiter plate assays, with an EC50 of 0.0031 ppm[2].
