Benzyl isothiocyanate, and other isothiocyanates in general, were found to be protective against pancreatic carcinogenesis in vitro [3] via expression of the p21/WAF1 gene. [4] A recent published study showed its restraining impact on obesity, fatty liver, and insulin resistance in diet-induced obesity mouse model.
They are all members of the order Brassicales, which is characterized by the production of glucosinolates, and of the enzyme myrosinase, which acts on glucosinolates to release isothiocyanates. [1] Sinigrin is the precursor to allyl isothiocyanate; Glucotropaeolin is the precursor to benzyl isothiocyanate
The main complication with this route is the competing formation of alkyisothiocyanates. "SN1-type" substrates (e.g., benzyl halides) tend to give the isothiocyanate derivatives. Some organic thiocyanates are generated by cyanation of some organosulfur compounds.
Isothiocyanates are conventionally written as two words. [4] The following are some glucosinolates and their isothiocyanate products: [4] Allylglucosinolate is the precursor of allyl isothiocyanate; Benzylglucosinolate (glucotropaeolin) is the precursor of benzyl isothiocyanate
The isothiocyanate further decomposes into hydroxybenzyl alcohols with the release of thiocyanates. [1] [2] [3] In the presence of a nitrile-specifier protein, the less toxic 4-hydroxyphenylacetonitrile is formed from the mustard oil glycoside instead. The cabbage butterfly exploits this mechanism to avoid the toxic effects of the ...
Glucotropaeolin or benzyl glucosinolate is a glucosinolate found in cruciferous vegetables, particularly garden cress. [1] Upon enzymatic activity, it is transformed into benzyl isothiocyanate , which contributes to the characteristic flavor of these brassicas .

MDI is commonly used in the manufacture of rigid foams and surface coating. [1] Polyurethane foam boards are used in construction for insulation. TDI is commonly used in applications where flexible foams are used, such as furniture and bedding. Both MDI and TDI are used in the making of adhesives and sealants due to weather-resistant properties.
