umifoxolaner (ML-878) is a γ-aminobutyric acid (GABA) regulated chloride channels antagonist. Umifoxolaner is an anti-parasitic agent[1]. | [Production Methods]
The synthesis of umifoxolaner involves constructing a chiral isoxazoline ring system and attaching multiple fluorinated aromatic groups to enhance its lipophilicity and target specificity. The process begins with a [3+2] cycloaddition reaction to form the (5S)-configured isoxazoline core, which is then functionalised with a 3-chloro-4-fluoro-5-(trifluoromethyl)phenyl group and a second trifluoromethyl substituent to boost metabolic stability and receptor binding. Separately, a naphthalene-1-carboxamide moiety is synthesised and linked via an amide bond to a difluoroethylamino-oxoethyl side chain, completing the pharmacophore. | [Mechanism of action]
