This chemical is called L-Proline, 5-oxo-L-prolyl-L-tryptophyl-L-prolyl-L-arginyl-L-prolyl-L-glutaminyl-L-isoleucyl-L-prolyl-, and it's also named as Bradykinin potentiator B, 2-L-tryptophan-3-de-L-leucine-4-de-L-proline-8-L-glutamine-. With the molecular formula of C₅₃H₇₆N₁₄O₁₂, its molecular weight is classification codes are Angiotensin-converting enzyme inhibitors; Antihypertensive agents; Cardiovascular Agents; Enzyme Inhibitors; Enzyme inhibitor [angiotensin-converting]. The CAS registry number of this chemical is 35115-60-7. Additionally, it's a synthetic nonapeptide (Pyr-Trp-Pro-Arg-Pro-Gln-Ile-Pro-Pro) which is identical to the peptide from the venom of the snake, bothrops jararaca. It inhibits kininase II and angiotensin I and has been proposed as an antihypertensive agent.
