1,10-Phenanthroline anhydrous 66-71-7 in stock for sales

o-Phenanthroline (anhydrous) is a heterocyclic organic compound, also named as 1,10-Phenanthroline, 1,10-diazaphenanthrene. It is an inhibitor of metallopeptidases, with one of the first observed instances reported in carboxypeptidase A. Inhibition of the enzyme occurs by removal and chelation of the metal ion required for catalytic activity, leaving an inactive apoenzyme. 1,10-Phenanthroline targets mainly zinc metallopeptidases, with a much lower affinity for calcium.
