Muscarinic thioligands with cyclopentane nucleus
Bioorganic & Medicinal Chemistry, 1996Some thio- and the benzoyl-derivatives of deoxamuscarine were synthesized and tested as muscarinic agonists using radioligand binding assays and functional tests. In comparison with deoxamuscarine, used as reference compound, no dimension/distance modification is tolerated for correct lipophilic pocket recognition.

Cyclopentane Peptide Nucleic Acids
2013Incorporating a cyclopentane ring into the two-carbon unit of a peptide nucleic acid backbone increases its binding affinity to complementary nucleic acid sequences. This approach is a general method to improve binding and can be applied at either purine or pyrimidine bases.

Equilibrium of Hydrogen + Cyclopentane and Carbon Dioxide + Cyclopentane Binary Hydrates
Journal of Chemical & Engineering Data, 2008Cyclopentane (CP) forms sII hydrates, in which CP only occupies the large cavities. Small gas molecules such as hydrogen and carbon dioxide can be encaged in the small cavities. However, there are no reported data on the equilibrium conditions of CP + H2 and CP + CO2 binary hydrates, which are essential to developing CO2 capturing or H2 enriching ...

Helvetica Chimica Acta, 1975
AbstractThe mass spectra of the three cyclopentane‐1,2,3‐triols, six cyclopentane‐tetrols and four cyclopentane‐pentols stereoisomers have been studied. Complex processes, especially regarding the H2O eliminations, were detected by extensive deuterium labelling.

Hydrate Equilibrium Conditions for Cyclopentane and a Quaternary Cyclopentane-Rich Mixture
Journal of Chemical & Engineering Data, 2001Experimental data on hydrate formation of cyclopentane and a 98.40 mass % purity cyclopentane mixture containing three impurities (0.48 mass % pentane, 0.48 mass % 2-methyl butane, and 0.72 mass % 2-methyl propane) in water were measured. The measurements were carried out in a transparent sapphire cell (100-cm3 effective volume) by applying a pressure ...

The pure rotational Raman spectrum of cyclopentane-d0 and cyclopentane-d10
Journal of Molecular Spectroscopy, 1963The pure rotational Raman spectra of C5H10 and C5D10 were photographed under high dispersion in the 13th order of a 300 grooves/mm plane grating using the line Hg 4358 A for excitation. The spectra are quite weak and diffuse and resemble that of a symmetric top rotator.

Infrared Spectra of Crystalline Cyclopentane and Cyclopentane-d10
The Journal of Chemical Physics, 1969Infrared spectra of crystalline cyclopentane and cyclopentane-d10 have been measured at different temperatures between 4000 and 200 cm−1. Spectroscopic evidence shows that form I (− 120°C) and form II (− 140°C) have the same degree of disorder as the liquid. In the ordered crystal form III (− 180°C) the molecule has a rigid bent conformation.

The Journal of Chemical Thermodynamics, 1974
Abstract Excess enthalpies for cyclopentane+cycloheptane at 288.15, 298.15, and 308.15 K and excess enthalpies for cyclohexane+cyclo-octane at 288.15, 298.15, 308.15, and 318.15 K have been measured with an isothermal displacement calorimeter. The excess volumes for cyclopentane+cyclohexane and cyclopentane+cycloheptane have been measured over a ...

Decomposition of cyclopentane on Ni(755): peculiar decomposition behavior of cyclopentane
Surface Science Letters, 1993Abstract Decomposition of cyclopentane on Ni(755) and −(111) has been investigated by temperature-programmed desorption (TPD). Adsorption of cyclopentane occurs on both surfaces by a precursor-mediated mechanism. On the (755) surface cyclopentane decomposes almost completely into adsorbed carbon and gaseous hydrogen while heating up from 123 to 573 K.
