The invention relates to a compound of formula I, and a preparation method and use thereof. The compound has a bacterial quorum-sensing regulatory effect, and can be used for prevention and/or treatment of a disease caused by a bacterial infection. 

Bacterial quorum sensing regulator and medical use thereof

A derivative of homoserine lactone represented by formula I, and a preparation method and use thereof. The compound has a bacterial quorum-sensing regulatory effect, and can be used for prevention and/or treatment of a disease caused by a bacterial infection. 

Derivative of homoserine lactone, and preparation method and use thereof

Aspects of this disclosure relate to protecting a circuit, such as an amplifier, from transient overdrive events and/or average overdrive events. In one embodiment, an indication of average power, such as root mean squared (RMS) power of a radio frequency (RF) signal, can be compared to a first threshold and an indication of a peak RF power can be compared to a second threshold. When the indication of average power exceeds the first threshold, an average overdrive event can be detected. When the indication of peak power exceeds the second threshold, a peak overdrive event can be detected. If either a transient overdrive event or an average overdrive event is detected, a circuit, such as an amplifier, can be protected.
