BACKGROUND Since the mid-2000s synthetic cannabinoids have been abused as recreational drugs, prompting scheduling of these substances in many countries. To circumvent legislation, manufacturers constantly market new compounds; [1-(5-fluoropentyl)indol-3-yl]-(2,2,3,3-tetramethylcyclopropyl)methanone (XLR-11), the fluorinated UR-144 analog, is one of the most recent and widely abused drugs, and ...

In this work a Schiff base ester derived ligand [H2L1] were synthesized in three steps, first Synthesis of the pentanoiyl chloride from reaction thionyl with pentanoic acid.
 second step precursosr (W1), 4-[3-(3-hydroxy-1-methyl- butylideneamino)- 4-methyl-phenylimino]-pentan-2-ol ,was prepared by acetylaceton tolylen2,4-diamin . theird ligands precursor (W1)with to produce[H2L1] 1:2 mole ...

Thirty-two different volatile oils were identified from Allomyrina dichotoma (A. dichotoma) larvae by gas chromatography/mass spectrometry (GC/MS). The major volatile components were 2,2,4-trimethyl-3-carboxyisopropyl pentanoic acid isobutyl ester (5.83%), phenol,2,6-bis(a,a-dimethyl ethyl)-4-(1-methyl-1-phenylethyl) (5.72%), heptacosane (5.49%) and phenol,2,4-bis(1-methyl-1-phenylethyl) (5.47%...

The rancidity of rice bran is predominantly triggered by lipophilic enzyme activities. Bran stabilisation and defatting are the typical processes to inactivate that cause rancidity. However, little known about how this impacts development volatile compounds related odour in bran. effects post-milling process on secondary oxidation during storage were investigated. Based identified metabolites, ...

Valproic acid (2-propyl pentanoic acid) is a drug used for the treatment of epilepsy and bipolar disorder. Although very rare, side effects such as spina bifida and other defects of neural tube closure indicate that valproic acid interferes with developmental regulatory pathways. Recently obtained data show that valproic acid affects cell growth, differentiation, apoptosis and immunogenicity of...

Incubation of carboxyl-labeled fatty acids (RCi400H) with liver slices gave rise to Cl402 and labeled acetoacetic acid (1, 2). In the case of even numbered acids, much more of the radiocarbon appeared in the keto acid than was oxidized to C1402; however, the reverse situation occurred when acids of an odd number of carbons were used (2). Previously, studies made with non-labeled acids had yield...
