Indolebutyric acid (IBA) is a plant hormone in the auxin family. IBA promoted plant rooting and used commercially world wide to root many plant species. IBA considered to be toxic to animals and human. IBA demonstrated antineoplastic action in animal model. According to in silico and in vitro study IBA can act as competitive inhibitor to the phospholipase A₂ and may be used as anti inflammatory agent.

Apocholic acid is a product of mild dehydration of cholic acid. Apocholic acid is powerful complexing and enolizing agent, giving stable addition-compounds (“choleric acids”) with numerous organic molecules. It was shown, that apocholic acid is able to produce tumors in situ. Apocholic acid was found to have a decreasing effect on the cholesterol level of both the plasma and the liver of rats.

Penicillic acid (PA) is a polyketide mycotoxin produced by several species of Aspergillus and Penicillium species showed antibacterial activity against various plant pathogenic bacteria and can be as a lead molecule for the development of synthetic agrochemicals to control plant bacterial diseases. In addition, PA induces single-strand DNA breaks and inhibits DNA synthesis, demonstrating mutagenic and cytotoxic effects. Penicillic acid irreversibly inhibits GDP-mannose dehydrogenase (DMG), an alginate synthesis enzyme, interrupting the committed step in alginate biosynthesis.
