All told, the chemist of the School of Sciences synthesized 51 compounds whose biological characteristics were evaluated by two of the most prestigious groups in this area: the Mediterranean Institute of Neurobiology, located in Italy, and the Department of Pharmacology of the University of Oslo.
The results obtained formed part of his doctoral dissertation, entitled “Design, synthesis and preliminary biological evaluation of new derivatives of benzo[b]-thiophene in the Search for Agents for a New Anti-Depressant Therapy.”
As the researcher explained, the new molecules which he designed affect two brain targets which are considered to be keys in the development of processes of depression. One of these is the serotonin transporter, whose reuptake reduction has already been shown to improve mood; the other is the serotoninergic receptor 5-HT7, a therapeutic target for serotonin whose modulation can provoke anti-depressant effects.
Trials in vivo
In order to study these two key targets, Luis Berrade developed chemical structures via the fusion of two similar chemical compounds: the benzo[b]-thiophene ring and arilamine. Following this, he compared the new compounds with a drug currently on the market, Fluoxetine. As a result of this research, he explained, we discovered that nine of these compounds demonstrated greater affinity, in this sense, than the commercial drug. As a consequence of this discovery, in January in vivo trials were begun in order to test their anti-depressant activity in mice.
This study, one of the first in the world in this specialty, was undertaken in collaboration with the Department of Pharmacology of the University of Navarra. Among its objectives was discovering whether these new compounds could reduce the minimum time required for anti-depressant drugs to ameliorate the symptoms of the disease: Currently, the time for an antidepressant to take effect is from three to six weeks, and this is an important factor in patient refusal to continue with these treatments; as a result it is very important to shorten the time required for the positive effects to appear.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
