General description

2-Methyl-4-isothiazolin-3-one hydrochloride (MIT) is a derivative of the synthetic isothiazolinone.

Application

Methylisothiazolinone (MIT) has been used:
  • as a cytotoxic substance to investigate its effect on bronchial epithelial cells (BEAS-2B cells) and its role in apoptotic cell death
  • to study the effects of tyrosine phosphorylation on focal adhesion kinase (FAK) activity in the development of neural axons and dendrites

Biochem/physiol Actions

2-Methyl-4-isothiazolin-3-one hydrochloride (MIT) is a skin sensitizer known to cause contact dermatitis and allergy. It is extensively used in the cosmetic industry as a preservative. MIT is a neurotoxin and its prolonged exposure may lead to neuronal death and inhibition of neurite outgrowth.
