The GC-MS properties of the synthetic cannabinoid drug of abuse 3-(1-naphthoyl)-1-pentylindole (JWH-018) and all 5 of its' regioisomeric 1-naphthoyl substituted 1-n-pentylindoles are compared in this report. These compounds have the 1-naphthoyl-group attached at each of the possible substituent positions of the indole ring. The six compounds have the same(More)
A series of ten homologous and regioisomeric aminoketones related to the designer synthetic cathinone derivative MDPV were evaluated in this study. These compounds were prepared from a common precursor chemical, piperonal (3,4-methylenedioxybenzaldehyde). These aminoketones show major peaks in their mass spectra corresponding to the regioisomeric and(More)
A variety of N-(phenylsulfonyl)-N-phenylglycines 5, N-(phenylsulfonyl)-2-phenylglycines 6, and N-(phenylsulfonyl)anthranilic acids 7 were prepared as analogues of the N-(phenylsulfonyl)glycine 1 aldose reductase inhibitors. In the rat lens assay, several derivatives of 5 display greater inhibitory activity than the corresponding glycines 1, suggesting that(More)
A number of 4,7-disubstituted benzopyran-2-ones were synthesized and evaluated for crude rat lens aldose reductase inhibitory activity. Substituents on position 4 included CH3, CO2H, CH2CO2H, CH = CHCO2H, and CH2CH2CO2H. The aromatic substituents included OH, OCH3, OCOCH3, CH2CH3, and Cl. Also included in the study were(More)
A series of substituted N-[[(4-benzoylamino)phenyl]sulfonyl]amino acids (BAPS-amino acids) were synthesized by established methods, and the stereochemistry of the products was confirmed by HPLC analysis after chiral derivatization. When tested against aldose reductase (alditol:NADP+ oxidoreductase; EC 1.1.1.21; ALR2) isolated from rat lens, all of the(More)
The birth of the twenty first century has provoked a substantial rise in the use of designer drugs, such as synthetic cathinones, because of a decrease in the availability and purity of other drugs of abuse. The khat plant or Catha edulis, contains cathinone, the parent compound. Synthetic cathinones are sold under the name "bath salts" as a ploy to(More)
The stereochemical course of the synthesis of amphetamine from norephedrine and norpseudoephedrine is investigated using liquid chromatography. The results show that the chiral carbon common to both compounds remains unaffected during the reaction sequence. The presence of individual amphetamine enantiomers in the reaction products is determined by(More)
The effects of 4-bromo-2,5-dimethoxyphenethylamine (Nexus), 3,4-methylenedioxyamphetamine (MDA), 3,4-methylenedioxyphenyl-2-butanamine (BDB), and cathinone were studied in the newly hatched chicken and compared to the effects of d-amphetamine and three hallucinogens in the same species. Cathinone, a psychomotor stimulant in man (6), produced effects that(More)
AIMS There is a rapid increase in the use of methylenedioxymethamphetamine (MDMA) and its structural congeners/analogs globally. MDMA and MDMA-analogs have been synthesized illegally in furtive dwellings and are abused due to its addictive potential. Furthermore, MDMA and MDMA-analogs have shown to have induced several adverse effects. Hence, understanding(More)
