Synthesis, Insecticidal Activities, and 3D-QASR of N-Pyridylpyrazole Amide Derivatives Containing a Phthalimide as Potential Ryanodine Receptor Activators
摘要:
To develop potent and environment-friendly insecticides, novel N-pyridylpyrazole amide derivatives containing a phthalimide were designed and synthesized. The preliminary bioassay results showed that most of the target compounds exhibited good insecticidal activities. For oriental armyworm (Mythimna separata), compounds E5, E29, E30, and E33 displayed higher than 90% lethal rates at 25 mg L-1. In particular, compound E33 displayed 60% mortality at a lower concentration of 6.25 mg L-1. Besides, compound E33 also showed a 30% lethal rate at 5 mg L-1 against diamondback moth (DBM) (Plutella xylostella). Molecular docking between the most active compound E33 and DBM ryanodine receptor (RyR), comparative molecular field analysis (CoMFA), and density functional theory (DFT) calculations were conducted and discussed. Furthermore, according to vitro studies using a calcium imaging technique, compound E33 was a potent novel lead targeting insect RyR.

A series of compounds including N-aryl substituents of phthalimide and 4-nitrophthalimide were synthesized and evaluated for their anticonvulsant properties. The in vivo screening data suggest that all the analogs have the ability to protect against pentylenetetrazole-induced seizures. These compounds exerted their maximal effects 30 min after administration. The most potent compound in both, tonic and clonic seizure was 1-naphthyl derivative (comp. 6), which was more active than the reference drug known as Phenytoin. Using an open pore model of the Na channel, these anticonvulsants were docked in the active site and examined in relation to the residues identified by mutagenesis as important for their binding energies. Docking studies revealed that all compounds (1-13) interacted mainly with residues II-S6 of NaV1.2 by making hydrogen bonds and additional hydrophobic interactions with domain I and II in the channel's inner pore.
