General description

Methyl 1-(butylcarbamoyl)-2-benzimidazolecarbamate (Benomyl) is widely employed for the treatment of various fungal diseases in agriculture. It has been reported as an active constituent of DuPont Benlate fungicidal formulations. Kinetics of the degradation of benomyl in various organic solvents has been investigated by spectrophotometric methods. N,N′-Dibutylurea (DBU) has been reported as the major metabolite of benomyl.

Application

Methyl 1-(butylcarbamoyl)-2-benzimidazolecarbamate may be used as standard reagent for the HPLC quantification of benomyl in water, sediment and biota samples.

The antifungal agent benomyl [methyl-1-(butylcarbamoyl)-2-benzimidazolecarbamate] is used throughout the world against a wide range of agricultural fungal diseases. In this paper, we investigated the interaction of benomyl with mammalian brain tubulin and microtubules. Using the hydrophobic fluorescent probe 1-anilinonaphthalene-8-sulfonic acid

The neuronal cytoskeleton performs incredible feats during nervous system development. Extension of neuronal processes, migration, and synapse formation rely on the proper regulation of microtubules. Mutations that disrupt the primary α-tubulin expressed during brain development, TUBA1A, are associated with a
