본 발명은 전반적으로, 헤모글로빈의 일차 아민과 N 말단 발린에 숙신이미딜-발레르산염 활성화된 폴리에틸렌 글리콜의 접합에 의해 만들어진 폴리에틸렌 글리콜 (PEG) 접합된 헤모글로빈에 관계한다.
Description
도면 1은 메톡시 PEG 숙신이미딜 발레르산염 (mPEG-SVA)을 출발 물질로서 이용하여 아민 페길화된 헤모글로빈을 제조하기 위한 예시적인 방법의 흐름도를 묘사하고, 여기서 R1, R2와 R3은 헤모글로빈 주요 사슬의 부분이다.
도면 2는 (1) p-니트로페닐 탄산염-PEG (NPC-PEG), (2) 숙신이미딜탄산염-PEG (SC-PEG), (3) 말레이미드-PEG (Mal-PEG), 그리고 (4) 숙신이미딜 발레르산염-PEG (SVA-PEG)에 대한 화학적 구조와 결합 길이를 묘사하고, 여기서 화살표는 활성 기로부터 PEG 중추의 거리를 보여준다.
도면 3은 Mal-PEG (위쪽), SVA-PEG (중앙)와 SC-PEG (아래쪽)에 대한, 헤모글로빈을 갖는 연쇄 및 PEG 중추 사이에 거리를 묘사한다.
