Phenthiazamine was developed by Sekizawa et al. as a centrally acting anesthetic for fish. The time required to reduce the positive ganglionic potential in the sympathetic ganglion by phenthiazamine was prolonged in the presence of higher concentrations of Ca2+. The Ca2+-dependent action potential of guinea-pig ureter was reduced by this compound, whereas it did not affect the Na+-dependent action potential.

Erucic acid is a monounsaturated omega-9 fatty acid found mainly in the Brassica family of plants such as canola, rapeseed, wallflower seed, mustard seed as well as Brussels spouts and broccoli. Erucic acid has many of the same uses as mineral oils but with the advantage that it is more readily biodegradable. Its high tolerance to temperature makes it suitable for transmission oil. Its ability to polymerize and dry means it can be - and is - used as a binder for oil paints. Increased levels of eicosenoic acid (20:ln9) and erucic acid (22:1n9) have been found in the red blood cell membranes of autistic subjects with developmental regression. While studies done on laboratory animals in the early 1970s show that erucic acid appears to have toxic effects on the heart at high enough doses, an association between the consumption of rapeseed oil and increased myocardial lipidosis, or heart disease, has not been established for humans. While there are reports of toxicity from long-term use of Lorenzo's oil (which contains erucic acid and other ingredients), there are no reports of harm to people from dietary consumption of erucic acid. In 2003, Food Standards Australia set a provisional tolerable daily intake (PTDI) for an average adult of about 500 mg/day of erucic acid, extrapolated based on "the level that is associated with increased myocardial lipidosis in nursing pigs."
