The isothiocyanates present in the cruciferous plants were proved to have the antiproliferative and cytotoxic effect on cancer cell lines. Natural compounds in combination with chemotherapy agents enhance anticancer activities of drugs and reduce their toxicity. The aim of the presented study was to determine an effect of isothiocyanates and 5-fluorouracil used alone or in combination (in seque...

antifungal and antibacterial activities at concentrations of 7.8 to 15,6uglml, respectively, and that a possible target of the ITC compounds might be the cellular sulfhydryl group, In recent years, a number of multidrug transporters have been found in various organisms including bacteria and human cells.3) A promising way to conquer such multidrug resistance is to inactivate the eMux protein in...

Carbon-substituted isocyanates and isothiocyanates are common building blocks in organic synthesis. In contrast, synthetic uses of N-substituted isocyanates and isothiocyanates are severely underdeveloped: few have been reported and their reactivity had not been compared. Herein, we compare the reactivity of blocked (masked) N-isocyanate and N-isothiocyanate precursors in cascade reactions. Div...

An efficient synthesis of 1,3-thiazole drivatives is described via a three component reaction isothiocyanates, tetramethyl thiourea and ethyl bromopyruvate.

A one-pot, tandem process has been developed for the synthesis of a library of tetrazoles from aryl isothiocyanates. Condensation of aryl isothiocyanates with ammonia, and aryl amines (R-NH(2)) provided mono, 1,3-disubstituted symmetrical and unsymmetrical thioureas, which on desulfurization with molecular iodine (I(2)) led to formation of the corresponding heterocumulene (cyanamides or carbodi...

This paper deals with the synthesis of three up to date not described 4-(£>-terphenylyl)isothiocyanates and their six intermediates, two of which having not been described, too. A procedure was developed to identify £>-terphenyl derivatives by means of thin layer chromatography on alumina, as well as by gas chromatography. Infra-red and ultra-violet spectra were taken of the synthetized 4-(30-t...

PURPOSE Tamoxifen has been used for the treatment of estrogen receptor (ER)-positive breast cancers and in women who are at an increased risk of breast cancer. Acquired resistance to this drug and its toxicity still pose a clinically significant problem, especially in the prevention setting. Isothiocyanates present in cruciferous plants, such as sulforaphane or erucin, have been shown to reduce...

Isothiocyanates are bioactive dietary phytochemicals that react readily with protein thiol groups. We find that isothiocyanates are time-dependent inactivators of cysteine-dependent protein tyrosine phosphatases (PTPs). Rate constants for the inactivation of PTP1B and SHP-2 by allyl isothiocyanate and sulforaphane range from 2 to 16 M(-1)s(-1). Results in the context of PTP1B are consistent wit...

Isothiocyanates are versatile starting materials for a wide range of chemical reactions. However, their high nucleophilic susceptibility means they are best prepared and used immediately. We report here on a flow platform for the fast and efficient formation of isothiocyanates by the direct conversion of easily prepared chloroximes. To expedite this chemistry a flow insert cartridge containing ...
