LC-MS/MS method for the quantification of new psychoactive substances and evaluation of their urinary detection in humans for doping control analysis

The constant legal adaptation of new psychoactive substances (NPS), challenges their evaluation in different fields. In sports, NPS are prohibited in competition with a reporting limit (RL) of 50 ng/mL for the parent compound or a metabolite. However, there is a lack of comprehensive methodologies and excretion studies for monitoring NPS. This work aims to develop an analytical methodology for the NPS quantification and to evaluate the suitability of monitoring the urinary parent stimulants after NPS misuse. A method for the quantification of 14 common NPS was developed and validated. The method was found to be linear in the range 1-1000 ng/mL, and was shown to be accurate and precise. A lowest limit of quantification (LLOQ) of 1 ng/mL was established for all analytes except for benzylpiperazine (5 ng/mL). The method was able to confirm the identity of the analytes at the LLOQ for most NPS. The methodology was applied to the quantification of the parent compound in urine samples collected from an observational study where several healthy volunteers (n >= 6 per drug) ingested active doses of mephedrone (MEPH), methylone (MDMC), 2,5-dimetoxy-4-ethylphenetylamine (2C-E), or 6-(2-aminopropyl)benzofuran (6-APB). It was observed that for MDMC and 6-APB, the quantification of the urinary parent drug at the current RL is a proper strategy for detecting their misuse. However, this strategy seems to be insufficient for evaluating MEPH and 2C-E misuse. Monitoring the most abundant metabolite of MEPH (4 ‘-carboxy-MEPH) and the reduction of the RL to 10 ng/mL for the 2C-E evaluation are proposed.

Determination of the chain termination rate constants of the radical chain oxidation of organic compounds on antioxidant molecules by the QSPR method

A quantitative analysis of the structure-antioxidant activity relationship was performed for 128 derivatives of phenols, amines, uracil, benzopyrane, and benzofuran using the GUSAR 2013 program. Nine statistically significant QSAR consensus models characterized by a high accuracy of prediction of the chain termination rate constant of oxidation on the antioxidant molecules were constructed. The results of the structural analysis performed in the GUSAR 2013 program are in good agreement with the literature data.

Novel oxindole/benzofuran hybrids as potential dual CDK2/GSK-3 beta inhibitors targeting breast cancer: design, synthesis, biological evaluation, and in silico studies

The serine/threonine protein kinases CDK2 and GSK-3 beta are key oncotargets in breast cancer cell lines, therefore, in the present study three series of oxindole-benzofuran hybrids were designed and synthesised as dual CDK2/GSK-3 beta inhibitors targeting breast cancer (5a-g, 7a-h, and 13a-b). The N-1 -unsubstituted oxindole derivatives, series 5, showed moderate to potent activity on both MCF-7 and T-47D breast cancer cell lines. Compounds 5d-f showed the most potent cytotoxic activity with IC50 of 3.41, 3.45 and 2.27 mu M, respectively, on MCF-7 and of 3.82, 4.53 and 7.80 mu M, respectively, on T-47D cell lines, in comparison to the used reference standard (staurosporine) IC50 of 4.81 and 4.34 mu M, respectively. On the other hand, the N-1-substituted oxindole derivatives, series 7 and 13, showed moderate to weak cytotoxic activity on both breast cancer cell lines. CDK2 and GSK-3 beta enzyme inhibition assay of series 5 revealed that compounds 5d and 5f are showing potent dual CDK2/GSK-3 beta inhibitory activity with IC50 of 37.77 and 52.75 nM, respectively, on CDK2 and 32.09 and 40.13 nM, respectively, on GSK-3 beta. The most potent compounds 5d-f caused cell cycle arrest in the G2/M phase in MCF-7 cells inducing cell apoptosis because of the CDK2/GSK-3 beta inhibition. Molecular docking studies showed that the newly synthesised N-1-unsubstituted oxindole hybrids have comparable binding patterns in both CDK2 and GSK-3 beta. The oxindole ring is accommodated in the hinge region interacting through hydrogen bonding with the backbone CO and NH of the key amino acids Glu81 and Leu83, respectively, in CDK2 and Asp133 and Val135, respectively, in GSK-3 beta. Whereas, in series 7 and 13, the N-1-substitutions on the oxindole nucleus hinder the compounds from achieving these key interactions with hinge region amino acids what rationalises their moderate to low anti-proliferative activity.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 591-11-7 help many people in the next few years. Product Details of 591-11-7.

Pd(II)-Catalyzed, Bidentate Directing Group-aided Alkylation of sp(3)gamma-C-H Bonds: Access to 3-Alkylated Thiophene/Furan and Benzothiophene/Benzofuran Motifs

We report the Pd(II)-catalyzed bidentate directing group 8-aminoquinoline-aided sp(3)gamma-C-H alkylation of 3-methyl- thiophene/furan-2-carboxylic acid and 3-methyl- benzothiophene/benzofuran-2-carboxylic acid systems. While the 8-aminoquinoline-aided sp(3)gamma-C-H functionalization including arylation or amidation or amination of carboxylic acid derivatives are well known, however, the Pd(II)-catalyzed bidentate directing group 8-aminoquinoline-aided sp(3)gamma-C-H alkylation is not explored. Notably, 2- and/or 3-alkylated thiophene/furan and benzothiophene/benzofuran motifs are found in pharmaceutically active molecules. Accordingly, this work reveals the scope of the 8-aminoquinoline-aided sp(3)gamma-C-H alkylation method, and its usefulness by enriching the libraries of 3-alkylated thiophene/furan and benzothiophene/benzofuran motifs.
