(-)N-(chloroethyl)norapomorphine inhibits striatal dopamine function via irreversible receptor binding

B CostallV Nohria


beta-Haloalkylamine derivatives such as phenoxybenzamine are thought to irreversibly inactivate noradrenaline receptors by a process involving the formation of a reactive ethyleneimmonium cation which is followed by ring scission yielding the reactive carbonium ion which can then react further with a nucleophilic centre located on the receptor. Further study of catecholamine function has awaited the development of similar agents which can alkylate the dopamine receptor. We report here on the structure (Fig. 1) and evaluation of one agent with such potential, (--)N-(chloroethyl)norapomorphine [(--)NCA], and that this compound may be of significant value as a pharmacological and biochemical probe of the dopamine receptor.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
