Abstract
Description
도 2는 ATIPC-THAM-락토비온산(Lactobionic acid; LBA) (ATIPC-THAM-LBA; ATL)의 1H-NMR 스펙트럼 결과를 나타낸 것이다.
도 3은 ATIPC-THAM-LBA의 푸리에 변환 적외선 분광법(FT-IR) 결과를 나타낸 것이다.
도 6은 요오드가 포함된 생체적합성 단분자 CT 조영제를 투여한 후, X-선 감쇄 효과를 micro-CT 분석으로 확인한 것이다.
도 7은 요오드가 포함된 생체적합성 단분자 CT 조영제(ATL)를 투여한 후, 생체 수용체와의 친화도를 공초점 현미경으로 확인한 것이다.
도 8은 요오드가 포함된 생체적합성 단분자 CT 조영제(ATL)를 투여한 후, 시간에 따른 체내 CT 이미지 변화를 확인한 것이다.
도 9는 요오드가 포함된 생체적합성 단분자 CT 조영제(ATL)를 투여한 후, 시간에 따른 주요 장기별 CT 신호 강도의 변화를 확인한 것이다.
도 10은 요오드가 포함된 생체적합성 단분자 CT 조영제(ATL)를 투여한 후, 시간에 따른 담낭과 담도의 CT 이미지 및 조영 증강 분포 변화를 확인한 것이다.
도 11은 담도질병 모방 랫드 동물모델에서 요오드가 포함된 생체적합성 단분자 CT 조영제(ATL)의 담도 이상 여부 진단 능력을 확인한 것이다.
도 12는 요오드가 포함된 생체적합성 단분자 CT 조영제(ATL)를 투여한 후, 체내 안정성을 각 조직에서의 헤마톡실린 & 에오신 염색으로 확인한 것이다.
바람직하게는, 상기 화학식 1로 표시되는 화합물은 아시알로당단백질 수용체(asialoglycoprotein receptor; ASGPR)와 결합하여 담도를 특이적으로 조영할 수 있다.
