Abstract:
본 발명은 허혈성 조직 영상을 위한 플루오르-18 표지 트리아자노난 유도체 또는 이의 약학적으로 허용가능한 염에 관한 것이다. 본 발명에 의한 트리아자노난 유도체 또는 이의 약학적으로 허용가능한 염은 금속 및 F-18과 팔면체 구조로 안정하게 착체를 형성하여 F-18을 80-90%의 우수한 수율로 표지할 수 있으므로 양전자 방출 방사선 의약품 제조시, 유용하게 사용될 수 있어, 간질, 뇌혈관 질환, 각종 암, 뇌신경계질환 및 관상동맥질환 등을 판단하는 양전자 단층촬영에 유용하게 이용될 수 있다.
Abstract:
PURPOSE: A fluorine-18 labeled triazanonane derivative for ischemic tissue imaging is provided to stably form a complex and to enable PET(Positron Emission Tomography) for determining stroma, cerebrovascular diseases, cancer, nervous diseases, and coronary artery diseases. CONSTITUTION: A triazanonane derivative is denoted by chemical formula 1. The derivative of chemical formula 1 forms a complex together with metals and fluoride. The metal includes aluminum, gallium, indium, thallium, yttrium, or ruthenium. A radiopharmaceutical product contains the derivative of chemical formula 1 and the complex of metals and fluoride as an active ingredient. A method for preparing the derivative of chemical formula 1 comprises: a step of dissolving NODA compounds of chemical formula 2 and a base in an organic solvent; a step of adding nitroimidazole or nitrotriazole compounds to prepare a compound of chemical formula 3; and a step of dissolving the compound of chemical formula 3 in the organic solvent and performing deprotection.

Abstract:
PURPOSE: A combination of bifunctional chelating agent and mannosyl phosphorus serum albumin and radioactive isotope labeling compound thereof are provided to easily label a compound and to ensure high lymphatic system absorption rate. CONSTITUTION: A bifunctional chelating agent-mannosyl phosphorus serum albumin is denoted by chemical formula 1, (Man-L_1)_n-A-(L_2-BCA)_m. In chemical formula 1, Man is mannosyl group; L1 and L2 are linker or direct bond; A is phosphorus serum albumin; BCA is bifunctional chelating agent of 4,7,10-tetraazecyclododecane-1,4,7,10-tetraacetic acid(DOTA) or 1,4,7-triazacyclononane-1,4,7-triacetic acid(NOTA). A drug for imaging immunocytes contains a radioactive isotope labeling compound. The immunocytes are lymphatic system or reticuloendothelial system.
