Abstract: The present invention provides a compound of formula (I) or the salt thereof: wherein R is at least one selected from the group consisting of unsubstituted C1-4 alkyl, C1-4 alkyl substituted by C6-18 aryl or —OR1, and —C(?O)Z. The compound is a type-S protein kinase inhibitor, which binds to an ATP-binding site and a substrate-recognition site of a protein kinase simultaneously. The present invention further provides a pharmaceutical composition, which includes a compound of formula (I) or a salt and a pharmaceutically acceptable carrier thereof. The present invention further provides a use of a compound of formula (I) or a salt thereof, which is for the manufacture of a protein kinase inhibitor as a drug.

Abstract: A hinged mobile electronic device. The hinged mobile electronic device comprises a body, a cover, a connecting portion, and a keyboard portion. The cover is hinged to the body between a first position and a second position. The connecting portion, connected between the body and the cover, comprises a control portion. The keyboard, disposed on the body, comprises a plurality of keys and an actuator connected to each key. When the cover hinges to the first position, the control portion exerts pressure on the actuator to actuate the keys. When the cover hinges to the second position, the control portion decompresses the actuator such that the keys become inoperative.
