New possible Research Chemicals – RC´s
New possible Research Chemicals – RC´s
(Attachment: Tabular initial self tests in English)
During the „
interview with a RC chemist“, it is expressed that pharmakologically reasoned proposals are searched for new Research-Chemicals with possible psychodelica character for synthesis and testing.
„War On Drugs“ will go on, and we must be possibly always one step ahead! Legalisation of the psychedelics makes progress only at a snail's pace, if at all.
I synthesized some new RC´s and made initial tests with myself. The results range from encouraging to disappointing. Details may be found in the English-written attachment.
The examples are intended as stimulations to others for further "Researches". It is important that one does not focus himself exclusively on the affinity constant K to the 5-HT2A-Receptor: higher binding affinity (smaller K value!) is not always combined with a higher psychedelic potency.
If one is interested, I can send on request (annabolaine[at]rocketmail.com) the two copies of the original literature (1.1 and 2.4MB!) I cited in the attachments (see below):
Lit.1: Schulze-Alexandru, Meike; Kovar, Karl-Artur; Vedani, Angelo (Institute of Pharmacy, University of Tubingen, 72076 Tubingen, Germany): „Quasi-atomistic Receptor Surrogates for the 5-HT2A Receptor: A 3D-QSAR* Study on Hallucinogenic Substances“, Quant. Struct.-Act. Relat. 1999, 18(6), 548-560, Wiley-VCH Verlag GmbH.
(*Quantitative Structure-Activity Relationship)
The last three sentences of this literatur: „The most promising candidate compound is a molecule which represents a hybrid structure between LSD and phenylalkylamines such as DOI. The binding affinity of this compound towards the 5-HT
2A-receptor is predicted to be K=3.2 nM, close to the experimental binding affinity of LSD (K
exp=2.5 nM). Some of these compounds have been synthesized in the meantime, allowing for a critical evaluation of our model.”
(These compounds have simple structures between amphetamines and LSD. I never found any article dealing with such compounds from 1999 till 2010.)
Lit.2: Molecular Pharmacology Fast Forward. Published on September 25, 2006 as doi:10.1124 / mol.106.0287; MOL #28720:
“Molecular interaction of serotonin 5-HT2A receptor residues Phe339(6.51) and Phe340(6.52) with super-potent N-benzyl phenethylamine agonists”,
Michael R. Braden, Jason C. Parrish, John C. Naylor, David E. Nichols, Department of Medicinal Chemistry and Molecular Pharmacology, School of Pharmacy and Pharmaceutical Sciences, Purdue University, West Lafayette, IN 47907.
This artikel deals with the known PEA-NBOMe.
Hope, that rocketmail accepts such big attachments.
Since I am still not able to post any attachments (I am still a greenlighter), You may find them here:
