Biological Activity

Tetramisole HCl is a racemic mixture and anthelmintic agent that targets nematode nicotinic acetylcholine receptors and inhibits alkaline phosphatase activity. By activating somatic nicotinic receptors, it causes persistent muscle depolarization, leading to spastic paralysis of susceptible parasites. Additionally, its inhibition of alkaline phosphatase modulates phosphate metabolism and cellular signaling pathways, contributing to its broad antiparasitic effects and utility in biochemical research.

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
