Images of L4 stage Caenorhabtis elegans: 32 larvae at a compound concentration equal to 250 µg/mL. (A)—control group, the black arrow indicates a live larva, in its sinusoidal form; (B–F)—representative images of compounds 1, 3, 5, 11, and 12, respectively; the black arrows point to a live larva in its characteristic shape (sinusoidal) and the orange arrow shows a dead larva in its characteristic rod shape.
