Abstract

To find $\alpha$-glucosidase inhibitors produced by Actinomycetes, bacteria belonging to Actinomycetes were isolated from soil sample using Bennett's medium. The inhibitory activity induced by these bacteria on $\alpha$-glucosidase, which is the key enzymes far carbohydrates digestion and the prevention of diabetic complications, was investigated. A strain of these bacteria, PM718 potently inhibited $\alpha$-glucosidase activity in vitro.

탄수화물분해 효소인 $\alpha$-glucosidase의 활성을 저해하는 물질을 생성하는 미생물을 검색하기 위하여 토양시료로 부터 수종의 미생물을 검색하였다. 토양 시료에서 강력한 $\alpha$-glucosidase 저해제를 생성하는 방선균PM718을 분리하였고 그 저해제의 활성을 기지물질인 acarbose와 비교 측정한 결과 우수한 활성을 나타냄을 확인하였다. 또한 그 활성은 pH 변화에도 안정된 활성을 유지하는 것을 확인하였다.
