Methylchloroisothiazolinone
Methylchloroisothiazolinone is a widely used fungicide and also an aquatic pollutant with pro-inflammatory activity and neurotoxicity. Methylchloroisothiazolinone induces the production of pro-inflammatory cytokines (such as IL-1β, TNF-α, IL-6) by activating the NF-κB signaling pathway and upregulating TLR4 expression, thereby triggering allergic contact dermatitis. Methylchloroisothiazolinone reduces cholinesterase activity and exacerbates oxidative stress by impairing catalase activity and disrupting redox balance. Methylchloroisothiazolinone poses significant harm to Mediterranean mussels, reducing the viability of hemocytes and digestive gland cells, inhibiting immune phagocytic function, and disrupting osmoregulatory capacity. Methylchloroisothiazolinone is used in studies on allergic contact dermatitis and related immunotoxicity mechanisms.

Methylchloroisothiazolinone (0.01-0.1 mg/L; 14 d) induces concentration-dependent cytotoxicity in hemocytes of the Mediterranean mussel (Mytilus galloprovincialis): cell viability decreases significantly at 0.01 mg/L, partially recovers at 0.1 mg/L, and lysosomal membrane stability reduces at both concentrations[2].
Methylchloroisothiazolinone (0.01-0.1 mg/L; 14 d) induces concentration-dependent cytotoxicity in isolated Mytilus galloprovincialis (Mediterranean mussel), with significant loss of cell viability and lysosomal stability at 0.01 mg/L, and partial recovery observed at 0.1 mg/L[2].
Methylchloroisothiazolinone (0.01-0.1 mg/L; 14 d) impairs the osmoregulatory capacity of digestive gland cells isolated from the Mediterranean mussel (Mytilus galloprovincialis)[2].
Methylchloroisothiazolinone (0.01-0.1 mg/L; 14 d) significantly reduces the phagocytic activity of hemocytes in Mediterranean mussels (Mytilus galloprovincialis)[2].
Methylchloroisothiazolinone (0.01-0.1 mg L-1; 14 days) induces concentration-dependent oxidative stress, biotransformation activation, and neurotoxicity in the digestive glands of Mediterranean mussels (Mytilus galloprovincialis)[2].
