A series of simple thiourea derivatives were designed based on the structure of natural product harmine and lead compound and synthesized from amines in one step. The antiviral activity of these thiourea derivatives was evaluated. Most of them exhibited significantly higher anti-TMV activity than commercial plant virucides ribavirin, harmine, and lead compound. The hydrogen bond was found to be important but not the more the better. The optimal compound (R,R)-20 showed the best anti-TMV activity in vitro and in vivo (in vitro activity, 75%/500 mu g/mL and 39%/100 mu g/mL; inactivation activity, 71%/500 mu g/mL and 35%/100 mu g/mL; curative activity, 73%/500 mu g/mL and 37%/100 mu g/mL; protection activity, 69%/500 mu g/mL and 33%/100 mu g/mL), which is significantly higher than that of Ningnanmycin. The systematic study provides strong evidence that these simple thiourea derivatives could become potential TMV inhibitors.
