Ni(II) protoporphyrin IX is a metalloporphyrin compound characterized by its limited propensity for axial ligation and its distortion upon binding to ferrochelatase.
Ga(III)protoporphyrin-IX, a model for interporphyrin interactions in malaria pigment, possesses potent antibacterial effects against gram-negative, gram-positive, and acid-fast bacteria. It exhibits high solubility in methanol (MeOH) and serves as a malarial pigment analogue for drug development, as well as a potential antibacterial agent.
