Stops, prevents or reduces the activity of an endopeptidase, any enzyme that hydrolyzes nonterminal peptide linkages in polypeptides.

Stops, prevents or reduces the activity of serine-type endopeptidases, enzymes that catalyze the hydrolysis of nonterminal peptide linkages in oligopeptides or polypeptides; a serine residue (and a histidine residue) are at the active center of the enzyme.
