Title
(EN) CARBOXYLIC ACID-INTRODUCED PSMA-TARGETING COMPOUND AND USE THEREOF
(KO) 카르복시산이 도입된 PSMA-표적 화합물 및 그의 용도
Abstract
(EN)
The present invention relates to a ^18F-labeled compound for diagnosing prostate cancer and a use thereof. A carboxylic acid-introduced compound of the present invention forms strong ion-pair bonds (salt-bridge interactions) with arginine residues present at PSMA protein-binding sites, thereby showing high binding affinity, and also having rapid background radiation removal effects in vivo due to the hydrophilic properties of carboxylic acid, and less non-specific binding. COPYRIGHT KIPO 2021

본 발명은 전립선암 진단을 위한 F-표지된 화합물 및 그의 용도에 관한 것으로, 본 발명의 카르복실산이 도입된 화합물들은 PSMA 단백질 결합부위에 있는 아르기닌(arginine) 잔기와의 강한 이온쌍 결합(Salt Bridge Interaction)을 형성하여 결합친화력이 높고, 카르복실산의 친수성 성질로 생체 내 빠른 배경방사능 제거 효과와 낮은 비특이적 결합을 갖는 특징이 있다. 18
