LADW
LADW is a tetrapeptide derived from the hydrolysate of tuna skeletal muscle myosin, with dual inhibitory activities against angiotensin-converting enzyme 1 (ACE1) and α-glucosidase. The IC50 value of LADW against ACE1 is 28.02 μM, while its IC50 value against Saccharomyces cerevisiae α-glucosidase is 4.40 mM. LADW binds competitively to the active site of ACE1, stabilizes the enzyme conformation, and blocks substrate binding. LADW binds to α-glucosidase to inhibit carbohydrate hydrolysis and can also alter starch structure. LADW can be used in studies related to hypertension and diabetes.

生物活性
LADW is a competitive inhibitor of purified ACE1, which binds to the active site of the enzyme or its adjacent region to block substrate binding. It potently inhibits purified ACE1 with an IC50 of 28 μM, exhibiting a concentration-dependent inhibitory effect[1].
LADW (150-300 μM; 24 h) promotes NO release and inhibits ET-1 secretion in EA.hy926 vascular endothelial cells in a concentration-dependent manner[1].
LADW forms strong interactions with eNOS, ECE-1 and Furin via hydrogen bonds and van der Waals forces and binds to the key active residues of these proteins according to molecular docking results[1].
LADW (15 min pre-incubation followed by 15 min reaction) potently inhibits α-glucosidase derived from Saccharomyces cerevisiae, with an IC50 value of 4.40 mM, and its inhibitory activity is stronger than that of EEAEGT[2].
LADW inhibits the hydrolysis of soluble starch during simulated gastrointestinal digestion by altering starch structure, reducing the production of reducing sugars by 39.56%[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
