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.
In organic chemistry, isothiocyanate is a functional group as found in compounds with the formula R−N=C=S. Isothiocyanates are the more common isomers of thiocyanates , which have the formula R−S−C≡N .
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 ...
Hence, this enzyme has one substrate, benzyl isothiocyanate, and one product, benzyl thiocyanate. This enzyme belongs to the family of isomerases, specifically those other isomerases sole sub-subclass for isomerases that do not belong in the other subclasses. The systematic name of this enzyme class is benzyl-thiocyanate isomerase.
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.
Thiocyanate complexes are not widely used commercially. Possibly the oldest application of thiocyanate complexes was the use of thiocyanate as a test for ferric ions in aqueous solution. [15] The reverse was also used: testing for the presence of thiocyanate by the addition of ferric salts. The 1:1 complex of thiocyanate and iron is deeply red.

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.
