The X-ray crystal structure determination of the glutaric acid-amide derivative, 4-ClC6H4N(H)C(=O)(CH2)3C(=O)OH (1), is described. The backbone of the molecule adopts an extended, all-trans configuration but the terminal carboxylic acid and phenyl resides are twisted out of the plane through the bridging atoms, as seen in the torsion angles of O(carboxylic acid)–C(m)–C(m)–C(m) [13.9(5)°] and C(m)–N–C(p)–C(p) [47.1(4)°]; m = methylene and p = phenyl.

Abstract:
Summary Emission of volatile organic compounds (VOCs) in plants is triggered by several biotic and abiotic factors, such as nutrient deficiency, environmental stress, and pathogenic attacks. For instance, plants suffering from limited or excessive nitrogen (N) supply may experience internal stress which can ultimately lower their stability and immunity making them susceptible to infection and infestation. In this study, VOCs from Capsicum annuum var. longum (Solanaceae) exposed to nitrogen (1.8 g/L, 4.5 g/L, and 9 g/L urea) were extracted using a 100 μm Solid Phase Microextraction (SPME) fiber

Background:Hydrazide-hydrazones constitute an important class of compounds for new drug development. In this study, a series of 39 new acylhydrazones (3-41), derived from (2S)-3-methyl- 2-[[(4-methylphenyl)sulfonyl]amino]butanoic acid hydrazide were synthesized with further aim to achieve biologically active acylhydrazones carrying an amino acid side chain.Methods:Compounds 3-41 were synthesized by microwave-assisted method. All synthesized compounds have been tested for their anti-HIV activity compound 21 was subjected to a new set of 2DNMR analysis for the characterization of the isomers in

Abstract:
An analogue of DL-methionine, Alimet, was evaluated for its commercial potential for increasing wool growth in Merino sheep in pen and grazing experiments. This was done by administering Alimet as a drench, in drinking water, or via rumen or abomasal fistula, and measuring wool growth rate and plasma methionine concentrations. In vivo data indicated that significant wool growth responses (23-35%) to Alimet as a drench or in drinking water occurred at low rates (estimated 5-6 g/sheep.day) of basal wool production when sheep were fed a lucerne diet to maintain liveweight.

Juglone (500 μM) promoted tobacco (Nicotiana tabacum L. ‘McNair 944’) callus growth, whereas catechol and phloroglucinol (500 μM) increased adventitious shoot formation, but not callus growth. Tannic acid increased the frequency of vitreous shoots. No phenolic compounds stimulated axillary shoot proliferation in blackberry (Rubus sp. ‘Dirkson Thornless’), and phloroglucinol (1 mM) inhibited shoot elongation. A
