Are there any other known inhibitors of rabbit lung Angiotensin Converting Enzyme (ACE), Product A6778?
Idrapril, the prototype of a new class of angiotensin converting enzyme (ACE) inhibitors, competitively inhibits, with nanomolar apparent Ki, the hydrolysis of hippuryl-glycyl-glycine by rabbit lung ACE.  Kinetic Ki and kon and koff values were 470 pM, 3.0±1.5×106 M-1 sec-1 and 1.4±0.3×10-3 sec-1, respectively.  Reference: Biochemical Pharmacology, 45(6), 1358-1362 (1993).
What is the medical significance of Angiotensin Converting Enzyme (ACE), Product A6778?
Angiotensin-converting enzyme (ACE) produces angiotensin II, a substance that affects the cardiovascular system in numerous ways, including narrowing of blood vessels. This narrowing can cause high blood pressure and cause the heart to work harder.  ACE inhibitors treat a variety of conditions, such as high blood pressure, scleroderma and migraines. (Mayo Clinic)
What is the effect of bleomycin on Angiotensin Converting Enzyme (ACE) activity in vivo?
Bleomycin causes a marked reduction in rabbit lung ACE activity. Reference: Cancer Research, 40, 3621-3626, (1980).
