INHIBITORY NEUROTRANSMITTERS AND THEIR INFLUENCE ON TUMOR IN PATIENTS WITH GLIOMAS

Сибирский онкологический журнал, 2016
The review deals with the problem of activity of gamma-aminobutyric acid (GABA), the major inhibitory neurotransmitter, in gliomas. It has been shown that GABA has an antitumor activity in most models and cancer patients have an increased level of GABA ...

Rubrolides A, D, P, T, U: Total Syntheses and Antibacterial Evaluation of Highly Brominated Marine Natural Products

ChemistryEurope, EarlyView.
Following the Danube Flow. The first total syntheses of highly brominated rubrolides T, U, and U‐analog, together with the efficient and divergent syntheses of rubrolides A, D, and P. The dibrominated key intermediate, obtained via a Suzuki‐Miyaura cross‐coupling reaction, is the centerpiece of the synthesis.

Detection of acetylcholinesterase activity and gamma-aminobutyric acid binding sites in Dicrocoelium dendriticum

Parasite, 2000
In the present study we report the presence of acetylcholinesterase activity and gamma-aminobutyric acid binding sites in crude extracts of Dicrocoelium dendriticum. This indirectly demonstrates the presence of acetylcholine and GABA.
