The present invention relates to (3-fluoro-2-hydroxy)propyl-functionalized aryl derivatives or to the pharmaceutically acceptable salt thereof, to a method for preparing same, and to a pharmaceutical composition containing same as active ingredients for the diagnosis or treatment of neurodegenerative brain diseases. The aryl derivatives of the present invention are (3-fluoro-2-hydroxy)propyl-functionalized to increase the polarity thereof, and therefore the drugs containing the aryl derivatives can easily permeate into the cerebrovascular membrane, thus increasing the effectiveness of the drugs. As the aryl derivatives of the present invention strongly bind to β-amyloid, the aryl derivatives, when labeled with radioisotope, can be used as a diagnostic agent for non-invasively diagnosing early Alzheimer's disease. Further, the aryl derivatives of the present invention bind to low molecular β-amyloid peptide conjugates to inhibit the generation of malignant high molecular β-amyloid plaque, and thus can be effectively used as a therapeutic agent for neurodegenerative brain diseases such as Alzheimer's disease.

본 발명은 (3-플루오로-2-히드록시)프로필기가 도입된 아릴 유도체 또는 이의 약학적으로 허용가능한 염, 이의 제조방법 및 이를 유효성분으로 함유하는 퇴행성 뇌질환의 진단 또는 치료용 약학적 조성물에 관한 것으로, 상기 아릴 유도체는 3-플루오로-2-히드록시)프로필기가 도입되어 극성이 증가하므로 약물의 뇌-혈관막 침투가 용이하여 약물의 효과가 증대되고, β-아밀로이드에 강하게 결합하므로 방사성 동위원소로 표지할 경우 비침습적인 방법으로 알츠하이머 질병을 조기에 진단할 수 있는 진단시약으로 활용될 수 있을 뿐만 아니라, 저분자의 β-아밀로이드 펩타이드 결합체와 결합하여 악성의 고분자 β-아밀로이드 침전체의 생성을 억제시키므로 알츠하이머 질병과 같은 퇴행성 뇌질환의 치료제로 유용하게 이용될 수 있다.

lipophilicities of the compounds. Intriguingly, (S)-configured PET tracers, (S)-[18F]1b and (S)-[18F]1c, exhibited a 2.8 and 4.0-fold faster brain washout rate at a peak/30 min in the mouse brain than the corresponding (R)-configured PET tracers despite there being no meaningful difference in binding affinities toward Aβ plaque. A further evaluation of (S)-[18F]1c with healthy rhesus monkeys also revealed excellent
