Background:
Captopril-d3 is intended for use as an internal standard for the quantification of captopril by GC- or LC-MS. Captopril is a first generation nonpeptidic ACE inhibitor (IC50 = 6.3 nM) that was designed based on bradykinin-potentiating peptides isolated from the venom of B. jararaca, a pit viper native to Brazil. 1,2,3 It does not exhibit a domain preference for binding either the C- or N-terminal active sites of the somatic form of ACE.1 Acute and chronic administration of captopril reduces blood pressure in spontaneously hypertensive Wistar-Kyoto rats and does not induce hypotension in salt-repleted normotensive Wistar-Kyoto rats.4 Captopril is also a competitive and reversible inhibitor of leukotriene (LTA4) hydrolase, which results in the disruption of LTB4 synthesis with an IC50 value of 14 μM.5
