3,3′,4′,5-Tetrachlorosalicylanilide (TCSA) is an apoptosis-inducing photosensitizer for keratinocytes. It was studied as a causative agent of photo contact dermatitis and drug photosensitivity. TCSA was used as a metabolic uncoupler in activated sludge biological wastewater treatment systems to reduce the amount of the produced sludge.

Sample Use Guides

BALB/c mice were painted with 5 uL of 0.1% TCSA on the earlobes and irradiated with 16 J/cm2 (at 365 nm) of UVA.
Route of Administration: Topical
In Vitro Use Guide
Curator's Comment: Without UVA, caspase-3 was not activated. TCSA was identified as apoptosis-inducing photosensitizers for keratinocytes.
HaCaT keratinocytes were incubated with 3,3',4',5-tetrachlorosalicylanilide (TCSA), bithionol, diphenylhydramine, chlorpromazine, 6-methylcoumarin, sparfloxacin, and enoxacin at 10(-7) to 10(-4)M and irradiated with UVA at 4J/cm(2). In a comparison with non-irradiated cells, significant apoptosis was found in TCSA, bithionol, chlorpromazine, sparfloxacin and enoxacin at 10(-4) or 10(-5)M as well as 8-MOP as assessed by both annexin V and active caspase-3 stainings, while necrosis occurred in most of these chemicals at 10(-4)M.
