Aminopeptidase B Inhibitors

Aminopeptidase B inhibitors span multiple chemical classes, ranging from direct enzyme inhibitors to those that act more peripherally by modifying the enzyme's operational environment. Direct inhibitors such as Bestatin, Amastatin, and Actinonin, function by binding to the active site of Aminopeptidase B. This impedes the enzymes capacity to hydrolyze peptide bonds, especially in removing basic amino acids from peptides. These chemicals exert their effects without the need for intermediary steps, providing immediate inhibitory action. Metal chelating agents like EDTA and Phenanthroline operate by sequestering metal ions that are crucial for the enzymes catalytic activity. By doing so, these agents result in a direct inhibition of the enzyme's function, affecting its role in amino acid modification.Other inhibitors, such as Leupeptin and PMSF, affect the availability of substrates on which Aminopeptidase B acts. These chemicals inhibit serine and cysteine proteases, which are upstream in the proteolytic cascade that eventually provides substrates for Aminopeptidase B. Puromycin and Chloroquine operate via a different mechanism. Puromycin inhibits protein synthesis at the ribosomal level, thereby reducing the number of peptide substrates available for Aminopeptidase B to act upon. Chloroquine disrupts endosomal acidification, which could alter the intracellular pH conditions under which Aminopeptidase B operates optimally. This represents an indirect modulation of the enzymes function by changing the cellular milieu to conditions less favorable for its activity.
