Abstract:
The present invention relates to a curcumin derivative, a method for producing same, and a photo-acoustic imaging agent comprising the curcumin derivative for detecting beta-amyloid plaque. The curcumin derivative, expressed by chemical formula 1, according to the present invention exhibits superb selective bonding with beta-amyloid, thereby allowing beta-amyloid to be detected by means of an optical or photo-acoustic imaging methods, and, particularly, the curcumin derivative can highly effectively detect photo-acoustic signals with almost no noise by reacting to irradiation of light having a particular wavelength range, and thus can be useful as a composition for detecting beta-amyloid and for diagnosing diseases caused by excessive production of beta-amyloid.

Claim (Index 3):
The curcumin derivative or the pharmaceutically acceptable salt thereof according to  claim 1 , wherein R is 3-hydroxy or 4-hydroxy.
