Discovery of FM-2665 as a Potent Arylpyrazole Insecticidal and Acaricidal Candidate: Rational Design via Pyridine Bioisosterism and Terminal Alkyl Optimization.
Sixteen novel arylpyrazole derivatives were designed using tigolaner as a scaffold reference and synthesized to examine the effects of pyridine bioisosterism and terminal alkyl modification. Among the synthesized compounds, FM-2665 (A14) showed the highest overall activity against Plutella xylostella, Tetranychus cinna...
