Abstract
Description
도 2는 본 발명의 실시예에 따라 제조된 엠파글리플로진/시트릭산 공결정, 공지된 엠파글리플로진, 시트릭산, 그리고 엠파글리플로진/시트릭산 혼합물의 분말 X선 회절(PXRD)패턴 결과를 보여준다. 이 패턴에서 파란색은 엠파글리플로진/시트릭산 공결정, 검정색은 엠파글리플로진, 빨간색은 시트릭산 그리고 연두색은 엠파글리플로진/시트릭산 혼합물을 보여주는데 피크가 서로 상이하게 다르다는 것을 보여준다.
도 3은 본 발명의 실시예에 따라 제조된 엠파글리플로진/시트릭산 공결정의 온도시차주사열량(DSC)의 열량곡선 결과를 보여준다.
도 4는 본 발명의 실시예에 따라 제조된 엠파글리플로진/시트릭산 공결정, 공지된 엠파글리플로진, 시트릭산, 그리고 엠파글리플로진/시트릭산 혼합물의 온도시차주사열량(DSC)의 열량곡선 결과를 보여준다. 이 결과에서 엠파글리플로진/시트릭산 공결정은 새로운 흡열피크를 갖는다는 것이 확인된다.
도 5는 본 발명의 실시예에 따라 제조된 엠파글리플로진/시트릭산 공결정의 핵자기공명분광(NMR) 1H-NMR 스펙트럼 결과를 보여주는데, 이 결과에서 엠파글리플로진/시트릭산의 화학양론적 비율이 1:1로 정확하게 그 피크가 적분 되어 나타난다.
도 6은 본 발명의 실시예에 따라 제조된 엠파글리플로진/시트릭산 공결정 그리고 엠파글리플로진 결정형의 1 mg/mL의 농도의 수용해성을 비교 시험한 결과이다. 이때 본 발명의 엠파글리플로진/시트릭산 공결정은 모두 용해가 되었지만 엠파글리플로진 결정형은 용해도가 낮아서 용해되지 않는다.
