Glucosinolates from seed meals of Erysimum hieracifoliwn and l\1alcolmia mantlma were treated with thioglucosidase (EC 3.2.3.1). and the resultant aglucon products investigated. A major product from E. hieracifoliwll was 3-hydroxypropyl isothiocyanate from the novel precursor 3-hydroxypropylglucosinolate. Other aglucon products were 3-methylsulfonylpropyL 3-methylsulfinylpropyl. 3-methylthiopro...

sulforaphane, an isothiocyanate found in broccoli and other cruciferous vegetables. it is an antioxidantand anti-cancer agent, and reduces blood pressure, and also has anti-allergic effects.in this article, six theoretical methods have been used for calculation of physical parameters insolforaphane and several similar compounds. we calculated physical parameters like atomic charges.energy (ae) ...

UNLABELLED Although widely used in air quality regulatory frameworks, the term "volatile organic compound" (VOC) is poorly defined. Numerous standardized tests are currently used in regulations to determine VOC content (and thus volatility), but in many cases the tests do not agree with each other, nor do they always accurately represent actual evaporation rates under ambient conditions. The pa...

A series of five membered heterocyclics was synthesized by the reaction between isoniazid and various substituted isothiocyanates and was tested for their anticonvulsant activity by determining their ability to provide protection against convulsions induced by electroconvulsometer. Among the synthesized compounds, (IIf) 2-(4-chlorophenyl)amino-5-(4-pyridyl)-1,3,4-thiadiazole and (IIIf) 2-(4-chl...

Ethyl pyruvate (EP) on reacting with malononitrile or isothiocyanates gives the pyridine derivati ves 5 and 9a , b , respecti vely. Chalcone deri vati ve of EP reacts with malononitrile to yield the pyran derivative which in turn IS transformed into pyridine derivative 14. Reactivity of 5 and 9a towards di fferent organic reagents has been investigated . Antimicrobial activity of some newly syn...

The isoxazole derivatives are interesting objects for synthesis in the search for various sorts of biological activity. Looking for more active immunomodulators we synthesized a series of 5-amino-3-methyl-4-isoxazolecarboxylic acid semicarbazides and thiosemicarbazides in the reaction of 5-amino-3-methyl-4-isoxazolecarboxylic acid hydrazide with isocyanates and isothiocyanates. The biological e...

Starting with 35 grams of ethyl aminoacetate we recovered practically one-half of the aminoacid ester in the form of its hydrochloride, and obtained 19 grams of the isothiocyanacetate. This reaction isbeing investigated further and will be applied for the preparation of other new types of polyketide mustard oils. If this method of synthesis finds as wide an application as we anticipate, it will...

Hydroxy isothiocyanates, especially 2-(4-hydroxyphenyl)ethyl isothiocyanate (hITC), were examined for antimicrobial synergism with streptomycin (SM) against Escherichia coli. On the course of those experiments, a peculiar suppression of SM by a low concentration of hITC was observed, besides the antibacterial synergism of hITC with SM. Further, bactericidal activity of SM in physiological salin...
