Pharmakologische Informationen

Pharmacodynamics · 1 Eintrag

PCL-016 or Picolinic acid drug substance is a pyridine carboxylate metabolite of tryptophan. It acts as an anti-infective and immunomodulator through its role in zinc transport. ZFPs are involved in viral replication and packaging as well as normal cell homeostatic functions. Picolinic acid has been shown to be an anti-viral in vitro and in vivo.

Mechanism of ActionAs a therapeutic agent, the molecule works by binding to zinc finger proteins (ZFPs) in a way that changes their structures and disrupts zinc binding, inhibiting function.

MeSH Pharmacological Classification · 1 Eintrag

Organic chemicals that form two or more coordination links with an iron ion. Once coordination has occurred, the complex formed is called a chelate. The iron-binding porphyrin group of hemoglobin is an example of a metal chelate found in biological systems.
