Thiourea catalysts accelerate aminolysis of N-acyl homoserine lactones (AHLs), molecules integral to bacterial quorum sensing. The catalysts afford rate enhancement of up to 10 times the control in CD3CN. Mild catalysis in other polar aprotic solvents is still observed, while the activity is attenuated in polar protic solvents.

氨基溶解,AHLs 是细菌法定人数感应不可或缺的分子。催化剂在 CD3CN 中的速率可提高到对照组的 10 倍。在其他极性非质子溶剂中仍能观察到温和的催化作用,而在极性质子溶剂中活性则有所减弱。
