FRONTIER ORBITALS AND IR FREQUENCIES OF CYCLIC HYDROXAMIC ACIDS RELATED TO ANTIMICROBIAL ACTIVITY
(Sociedad Chilena de Química, 2001)
A screen of worldwide wheat cultivars for hydroxamic acid levels and aphid antixenosis
(1992)
In a screen of seedlings of a worldwide range of 47 cultivars of Triticum (mainly T. aestivum) the concentration of the hydroxamic acid DIMBOA ranged between 1 and 8 mmol/kg fresh wt. In a bioassay in which alatae of the ...
Hydroxamic acid content of triticum species
(Kluwer Academic Publishers, 1988)
Fifty-five accessions of Triticum species were analyzed for content of hydroxamic acids (Hx), a natural resistance factor against various organisms. Hx were found in all accessions analyzed. Extreme values were found in ...
Accumulation of hydroxamic acids during wheat germination
(1999)
Hydroxamic acids, quantified by HPLC, varied in concentration between three cultivars of wheat. Seeds, roots, leaves and the entire plants were analysed separately. No hydroxamic acids were present in seeds throughout the ...
Chemosensitizing activity of histone deacetylases inhibitory cyclic hydroxamic acids for combination chemotherapy of lymphatic leukemia
(Bentham Science Publishers B.V., 2018)
Allelopathic effect of hydroxamic acids from cereals on Avena sativa and A. Fatua
(1990)
2,4-Dihydroxy-7-methoxy- 1,4-benzoxazin-3-one (DIMBOA), the main hydroxamic acid of wheat, and its decomposition product 6-methoxy-benzoxazolin-2-one (MBOA), inhibited 50% root growth of wild oat, Avena fatua at concentrations ...
Substrate specificity of a glucosyltransferase and an N-hydroxylase involved in the biosynthesis of cyclic hydroxamic acids in gramineae
(1994)
Microsomal preparations from maize seedlings exhibited N-hydroxylase activity with 2-hydroxy-1,4-benzoxazin-3-one (HBOA) as substrate, but not with its 7-methoxy analogue (HMBOA), or their corresponding 2-O-β-d-glucosides. ...
The HNO donor ability of hydroxamic acids upon oxidation with cyanoferrates(III)
(Taylor & Francis Ltd, 2015-09)
The hydroxamic acids (RC(O)NHOH, HA) exhibit diverse biological activity, including hypotensive properties associated with formation of nitroxyl (HNO) or nitric oxide (NO). Oxidation of two HAs, benzohydroxamic and ...
An efficient method for the quantification of hydroxamic acids from wheat by thin layer chromatography-densitometry
(John Wiley and Sons Ltd, 1998)
A new method is described for the quantification of 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA) and 2,4-dihydroxy-1,4-benzoxazin-3-one (DIBOA), the main hydroxamic acids in wheat and rye extracts, respectively, ...
