Chemical Synthesis of a Functional Fluorescent-Tagged α-Bungarotoxin

open access: yesToxins, 2022
α-bungarotoxin is a large, 74 amino acid toxin containing five disulphide bridges, initially identified in the venom of Bungarus multicinctus snake. Like most large toxins, chemical synthesis of α-bungarotoxin is challenging, explaining why all previous ...

Synthesis of 1,4-dihydro-2-methyl-4-oxo-nicotinic acid: Ochiai's route failed

open access: yes, 2006
The synthesis of 1,4-dihydro-2-methyl- and 1,4-dihydro-1,2-dimethyl-4-oxo-nicotinic acids was accomplished following a route other than Ochiai’s procedure, which yielded the isomer 1,6-dihydro-2-methyl-6-oxo-nicotinic acid ethyl ester, and not the 4-oxo ...

Structural correlates of affinity in fetal versus adult endplate nicotinic receptors

open access: yesNature Communications, 2016
Adult and fetal nicotinic acetylcholine receptors (AChRs) have different functional requirements and affinity for ACh. Here, the authors use molecular dynamics and electrophysiology to investigate this affinity, and identify four amino acids that when ...

NACHO Engages N-Glycosylation ER Chaperone Pathways for α7 Nicotinic Receptor Assembly

open access: yesCell Reports, 2020
Summary: The α7 nicotinic acetylcholine receptor participates in diverse aspects of brain physiology and disease. Neurons tightly control α7 assembly, which relies upon NACHO, an endoplasmic reticulum (ER)-localized integral membrane protein.

The effects of solvents and structure on the electronic absorption spectra of the isomeric pyridine carboxylic acid N-oxides [PDF]

open access: yesChemical Industry and Chemical Engineering Quarterly, 2013
The ultraviolet absorption spectra of the carboxyl group of three isomeric pyridine carboxylic acids N-oxides (picolinic acid N-oxide, nicotinic acid N-oxide and isonicotinic acid N-oxide) were determined in fourteen solvents in the wavelength range ...

Structurally similar allosteric modulators of α7 nicotinic acetylcholine receptors exhibit five distinct pharmacological effects. [PDF]

open access: yes, 2015
Activation of nicotinic acetylcholine receptors (nAChRs) is associated with the binding of agonists such as acetylcholine to an extracellular site that is located at the interface between two adjacent receptor subunits.

Pyridinium salts of dithiophosphoric acids on the basis of nicotinic acids and their isomers, 3-hydroxypyridine, and 3-pyridinemethanol

open access: yes, 2019
A new series of chiral carboxypyridinium dithiophosphates were synthesized by the reactions of nicotinic, isonicotinic, and picolinic acids with dithiophosphoric acid on the basis (1S)-endo-(–)-borneol in benzene or ethanol.
