Although many anti-PVY agents are designed to focus on the functionally important coat protein (CP) of virus, how these drugs act on CP to inactivate viral pathogenicity, remains largely unknown. Herein, a PVY CP inhibitor -3j (S) is disclosed, which is accessed by developing unusually efficient (up to 99% yield) and chemo-selective (> 99:1 er in most cases) carbene-catalyzed [3+4] cycloaddition reactions. Compound -3j bears a unique arylimidazole-fused diazepine skeleton and shows chirality-preferred performance against PVY. In addition, -3j (S) as a mediator allows ARG191 (R¹⁹¹) of CP to be identified as a key amino acid site responsible for intercellular movement of virions. R¹⁹¹ is further demonstrated to be critical for the interaction between PVY CP and the plant functional protein NtCPIP, enabling virions to cross plasmodesmata. This key step can be significantly inhibited through bonding with the -3j (S) to further impair pathogenic behaviors involving systemic infection and particle assembly. The study reveals the in-depth mechanism of action of antiviral agents targeting PVY CP, and contributes to new drug structures and synthetic strategies for PVY management.21:T426,A total of 35 piperazine derivatives were designed and synthesized, and their activities against tomato spotted wilt virus (TSWV) were evaluated systematically. Compounds 34 and 35 with significant anti-TSWV activity were obtained. Their EC₅₀ values were 62.4 and 59.9 μg/mL, prominently better than the control agents ningnanmycin (113.7 μg/mL) and ribavirin (591.1 μg/mL). To explore the mechanism
