Running title: Hydrogen bonding in 7 nAChR function
A series of arylidene anabaseines were synthesized to probe the functional impact of hydrogen bonding on the human 7 nicotinic acetylcholine receptor (nAChR) activation and desensitization. The aryl groups were either hydrogen bond acceptors (furans), donors (pyrroles) or neither (thiophenes). These compounds were tested against a series of point mutants of the ligand binding domain residue Q5...

molecules to evolve in the test tube. With the discovery of catalytic RNA, and advances in nucleic acid amplification techniques such as the polymerase chain reaction, it became possible to construct laboratory systems that allow the Darwinian evolution of functional RNA (and later DNA) molecules. This is not evolution based on natural selection, but rather directed evolution based on selection...
متن کاملHydrogen Bonding in Water
Hydrogen bonding occurs when an atom of hydrogen is attracted by rather strong forces to two atoms instead of only one, so that it may be considered to be acting as a bond between them [99]. Typically hydrogen bonding occurs where the partially positively charged hydrogen atom lies between partially negatively charged oxygen and/or nitrogen atoms, but is also found elsewhere, such as between fl...
متن کاملExtensive hydrogen and halogen bonding, and absence of intramolecular hydrogen bonding between alcohol and nitro groups in a series of endo-nitronorbornanol compounds.
The influence of the substituent at the C2 position on the hydrogen-bonding patterns is compared for a series of five related compounds, namely (±)-3-exo,6-exo-dibromo-5-endo-hydroxy-3-endo-nitrobicyclo[2.2.1]heptane-2-exo-carbonitrile, C(8)H(8)Br(2)N(2)O(3), (II), (±)-3-exo,6-exo-dibromo-6-endo-nitro-5-exo-phenylbicyclo[2.2.1]heptan-2-endo-ol, C(13)H(13)Br(2)NO(3), (III), (±)-methyl 3-exo,6-ex...
متن کاملStudy of Nitro Factor Dislodgement in Fox-7
Since FOX-7 (1, 1-diamino-2, 2-dinitroethylene) is a relatively new energetic material, little is known about its physical and chemical properties. Therefore, first-principles quantum chemical calculations are used to predict the energies of atoms of FOX-7. Under gentle heating (thermolysis) is likely to cause hydrogen transfer between molecules, producing highly reactive chemical species. Conv...
