Abametapir

Abametapir is a building block and an insectide.^1,2,3 It has been used in the synthesis of lanthanide coordination complexes with antifungal activity against C. albicans and divalent vancomycin derivatives with antibacterial activity against vancomycin-resistant enterococci.^1,2 Abametapir is ovicidal to DDT- and permethrin-resistant head louse eggs (LC₅₀s = 0.108, 0.121, and 0.16% in isopropanol for 0-2-, 3-5-, and 6-8-day-old eggs, respectively).³ Formulations containing abametapir have been used in the topical treatment of head lice infestation.
