It is well known that allosteric modulators of muscarinic acetylcholine receptors can both diminish and increase the affinity of receptors for their antagonists. We investigated whether the allosteric modulators can also increase the affinity of receptors for their agonists. Twelve agonists and five allosteric modulators were tested in experiments on membranes of CHO cells that had been stably ...
The experimental vibrational circular dichroism, electronic circular dichroism, and optical rotatory dispersion spectra and corresponding quantum chemical predictions of 3,3'-diphenyl-[2,2'-binaphthalene]-1,1'-diol (VANOL) are used to confirm its absolute configuration as (+)(589)-(aR) or (-)(589)-(aS). A discrepancy in the literature crystal structure has been resolved by determining the X-ray...
Levene and Jacobs have formulated the structure of yeast nucleic acid as a tetranucleotide. The facts that led up to their formulation were: 1. The formation of four nucleosides on neutral or ammonia hydrolysis. 2. The formation of simpler nucleotides on hydrolysis with dilute mineral acids. 3. The presence of a phosphorus to nitrogen ratio which agreed quite well for t.he tetranucleotide theor...
