Abstract
- To discover new agrochemicals with prominent pesticidal properties, a series of novel β-naphthol derivatives containing benzothiazolylamino and various heteroaryl groups (8a-q) were efficiently synthesised via Betti reaction. The bioassay results showed that most of the synthesised compounds exhibited favourable insecticidal potentials, particularly towards oriental armyworm (50-100% at 200mg⋅L-1) and diamondback moth (50-95% at 10mg⋅L-1). Compounds 8b, 8f, 8g, 8j, 8k, 8n, and 8o possessed LC50 values of 0.0988-5.8864 mg⋅L-1 against diamondback moth. Compounds 8i, 8l, and 8 m also displayed lethality rates of 30-90% against spider mite at the concentration of 100mg⋅L-1. Overall, some compounds could be considered as new insecticidal/acaricidal leading structures for further investigation. The calcium imaging experiments revealed that 8h, 8i, and viii could activate the release of calcium ions in insect (M. separata) central neurons at a higher concentration (50mg⋅L-1). The SAR analysis provided valuable information for further structural modifications. [ABSTRACT FROM AUTHOR]
