Physical description & handling notes

• White or off-white crystalline powder; [MSDSonline]
• Solid
• >18.5 [ug/mL] (The mean of the results at pH 7.4)
• 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.

Documented Uses

• Iron-chelating agent that inhibits DNA synthesis; may interfere with iron-dependent production of stable free organic radical which is essential for ribonucleotide reductase formation of deoxyribonucleotides. [ChemIDplus]
• Synthetic Polymer MALDI Matrix Compounds
• 2-Pyridinecarboxylic acid: ACTIVE
• Investigated for use/treatment in acne, herpes labialis infections (cold sores), and venereal disease.
• 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.
• As 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.
