- Study of the synthesis, antiviral bioactivity and interaction mechanisms of novel chalcone derivatives that contain the 1,1-dichloropropene moiety
-
A series of novel chalcone derivatives that contain the 1,1-dichloropropene moiety was designed and synthesized. Bioactivity assays showed that most of the target compounds exhibited moderate to good antiviral activity against tobacco mosaic virus (TMV) at 500?μg/mL. Among the target compounds, compound 7h showed the highest in vivo inactivation activity against TMV with the EC50 and EC90 value of 45.6 and 327.5?μg/mL, respectively, which was similar to that of Ningnanmycin (46.9 and 329.4?μg/mL) and superior to that of Ribavirin (145.1 and 793.1?μg/mL). Meanwhile, the microscale thermophoresis and fluorescence spectroscopy experiments showed that the compound 7h had a strong interaction with the tobacco mosaic virus coat protein.

- Design, synthesis and insecticidal evaluation of aryloxy dihalopropene derivatives
-
Plutella xylostella (P. xylostella) is a highly migratory, cosmopolitan species and one of the most important pest of cruciferous crops worldwide. Pyridalyl as a novel class of insecticides has good efficacy against P. xylostella. On the basis of the commercial insecticide pyridalyl, a series of new aryloxy dihalopropene derivatives were designed and synthesized by using Intermediate Derivatization Methods. Their chemical structures were confirmed by 1H NMR, high-resolution mass spectrum (HRMS), and single-crystal X-ray diffraction analysis. The insecticidal activities of the new compounds against P. xylostella were evaluated. The results of bioassays indicated that most of the compounds showed moderate to high activities at the tested concentration, especially compounds 10e and 10g displayed more than 75% insecticidal activity against P. xylostella at 6.25 mg/L, while pyridalyl showed 50% insecticidal activity at the same concentration. The field trials result of the insecticidal activities showed that compound 10e as a 10% emulsifiable concentrate (EC) was effective in the control of P. xylostella at 75-150 g a.i./ha, and the mortality of P. xylostella for treatment with compound 10e at 75 g a.i./ha was equivalent to pyridalyl at 105 g a.i./ha.

- Synthesis and Insecticidal Activity of Novel Nitropyridyl-Based Dichloropropene Ethers
-
Dihalopropene ether insecticides are known for good features such as no cross-resistance to other insecticide classes and safety for mammals. Pyridalyl is the only currently commercialized dichloropropene ether insecticide; however, it contains a trifluoromethyl group, the synthesis of which requires harsh reagents and reaction conditions. To search for novel dihalopropene ethers with unique biological activities but without trifluoromethyl groups, a series of nitropyridyl-based dichloropropene ether analogues were synthesized by reacting nitro-based halopyridine with 2,6-dichloro-4-(3,3-dichloroallyloxy)phenol or 2,6-dichloro-4-(3,3-dichloroallyloxy)phenyl 3-hydroxypropyl ether. Bioassay showed that the compounds exhibited potent insecticidal activities against various lepidopteran pests. Particularly, 2,6-dichloro-4-(3,3-dichloroallyloxy)phenyl 3-(5-nitro-2-pyridyloxy)propyl ether (8e) was active against major agricultural pests, and its insecticidal potency was comparable to that of Pyridalyl. Besides the trifluoromethyl group in Pyridalyl, a nitro group on the 5-position of the pyridyl ring is also viable for the development of optimal insecticidal activity.
