Renin Inhibitors in Foodstuffs: Structure-Function Relationship
نویسندگان
چکیده
Renin, a highly specific aspartic proteinase originated from kidney, is a ratelimiting enzyme in renin-angiotensin system. Recently, we developed effective expression system for recombinant human (rh) renin using baculovirus-insect cell expression system, and simple and rapid assay method for rh-renin using internally quenched fluorogenic (IQF) substrate. Using the purified rh-renin and the IQF substrate, we constructed rapid and sensitive renin inhibitor screening system. Using the system, we found renin inhibitors in various foodstuffs. The isolation and characterization of renin inhibitors from soybean, rice, and wild vegetables and structure-function relationship of the inhibitors are also discussed.

متن کاملDevelopment and Validation of a Robust QSAR Model For Piperazine and Keto Piperazine Derivatives as Renin Inhibitors
Background: The renin is a key performer in the renin–angiotensin system, and it offers a resource for the beneficial action of hypertension and heart malfunction. The keto piperazine based renin inhibitors have shown greater potential and good biavaibility. Objective: To develop a highly efficient QSAR model for 80 piperazines and keto piperazines to predict renin enzyme inhibitory activity. M...
متن کاملThe renin-angiotensin system and right ventricular structure and function: The MESA-Right Ventricle Study
The pulmonary vasculature is an important site of renin-angiotensin metabolism. While angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers (collectively AIABs) have a role in left ventricular (LV) disease, the impact of AIABs on right ventricular (RV) function is unknown. AIAB use was determined by medication inventory during the Multi-Ethnic Study of Atherosclerosis ba...
