Conditions:

Thiouracil or 2-thiouracil was introduced in 1943 as the first thionamide anti-thyroid drug. Owing to a high frequency of adverse reactions, especially agranulocytosis, use of thiouracil was abandoned in favor of other, less toxic drugs. Thiouracil is not currently used as a thyrostatic drug in humans. Thiouracil inhibits thyroid activity by blocking the enzyme thyroid peroxidase. It is also it is a highly selective inhibitor of neuronal nitric oxide synthase, by interfering with the substrate- and tetrahydrobiopterin (BH(4))-binding to the enzyme. Due to its ability selectively accumulating in de novo-synthesized melanin in overactive melanin-producing cells and thus providing a means to localize melanoma cells, thiouracil can represent a useful new tool to identify modulators of human hair pigmentation.

Allyl isothiocyanate (AITC), also known as mustard oil, is one of the most common naturally occurring isothiocyanates, which occurs in many common cruciferous vegetables. Besides antimicrobial activity against a wide spectrum of pathogens, it showed anticancer activity in both cultured cancer cells and animal models, although the underlining mechanisms remain largely undefined. Allyl isothiocyanate is a TRPA1 and TRPV1 agonist and pungency and lachrymatory effects of Allyl isothiocyanate are mediated through the TRPA1 and TRPV1 ion channels. Allyl isothiocyanate irritates the mucous membranes and induces eczematous or vesicular skin reactions.
