Pharmacology of novel psychoactive substances [PDF]

open access: yes, 2016
This PhD work consists of an in vitro and in vivo part. In the in vivo part, we investigated the role of dopamine in the acute clinical effects of 3,4-methylenedioxymethamphetamine (MDMA, “ecstasy”) in healthy human subjects.

Nickel–NHC-Catalyzed Cross-Coupling of 2-Methylsulfanylbenzofurans with Alkyl Grignard Reagents [PDF]

open access: yes, 2014
NiCl2(PPh3)(IPr) catalyzes cross-coupling reactions of 2-methylsulfanylbenzofurans with alkyl Grignard reagents. Other nickel complexes such as NiCl2(dppe) failed to catalyze the same reaction. The alkylation is applicable to the synthesis of a couple of

Benzofuran derivatives and the thyroid [PDF]

open access: yesClinical Endocrinology, 2008
SummaryAmiodarone and dronedarone are two clinically important benzofuran derivatives. Amiodarone has been used widely for treating resistant tachyarrhythmias in the past three decades. However amiodarone and its main metabolically active metabolite desethylamiodarone can adversely affect many organs, including the thyroid gland.

Zinc–gold cooperative catalysis for the direct alkynylation of benzofurans

open access: yesBeilstein Journal of Organic Chemistry, 2013
The direct alkynylation of benzofurans was achieved for the first time using the hypervalent iodine reagent 1-[(triisopropylsilyl)ethynyl]-1,2-benziodoxol-3(1H)-one (TIPS-EBX) based on the cooperative effect between a gold catalyst and a zinc Lewis acid.

Processing waste printed circuit boards for material recovery [PDF]

open access: yes, 2007
PURPOSE We have investigated the use of pyrolysis for the processing of waste printed circuit boards (PCBs). The aim was to make the process of separating the organic, metallic, and glass fibre fractions of PCBs much easier and therefore make ...

Combined in vitro and in silico approaches to the assessment of stimulant properties of novel psychoactive substances – The case of the benzofuran 5-MAPB [PDF]

open access: yes, 2016
Novel psychoactive substances (NPS) are increasingly prevalent world-wide although their pharmacological characteristics are largely unknown; those with stimulant properties, due to interactions with the dopamine transporter (DAT), have addictive ...
