N-[2-(2,2-Di­methyl­propanamido)­pyrimidin-4-yl]-2,2-di­methyl­propanamide n-hexane 0.25-solvate hemihydrate

2013

The asymmetric unit of the title compound, C14H22N4O2·0.25C6H14·0.5H2O, contains two independent molecules of 2,4-bis(pivaloylamino)pyrimidine (M) with similar conformations, one water molecule and one-halfn-hexane solvent molecule situated on an inversion center. In one independentMmolecule, one of the twotert-butyl groups is rotationally disordered between two orientations in a 3:2 ratio. Then-hexane solvent molecule is disordered between two conformations in the same ratio. The water molecule bridges two independentMmoleculesviaO—H...O, N—H...O and O—H...N hydrogen bonds into a 2M·H2O unit, and these units are further linked by N—H...N hydrogen bonds into chains running in the [010] dire…

(Z)-4-(2-Naphthylamino)pent-3-en-2-one

2011

The title compound, C15H15NO, which was synthesized under solvent-free conditions by the reaction of acetoacetone and 2-naphthylamine, adopts a Z conformation about the C=C bond. The enamine–ketone fragment is approximately planar [maximum deviation = 0.026 (3) Å] and forms a dihedral angle of 39.78 (3)° with the naphthalene ring system. An intramolecular N—H...O hydrogen bond is observed.

Methyl 4-[5-(4-fluorophenyl)-4-(pyridin-4-yl)-1H-imidazol-2-ylsulfanyl]butanoate

2008

The title compound, C19H18FN3O2S, was synthesized in the course of studies on 2-alkylsufanylimidazoles as p38 mitogen-activated protein kinase inhibitors. The synthesis was achieved by nucleophilic substitution of 4-(4-fluorophenyl)-5-(pyridin-4-yl)-1,3-dihydroimidazole-2-thione with methyl 4-bromobutanoate. The five-membered heterocycle makes dihedral angles of 32.4 (2) and 18.3 (2)° with the fluorophenyl and pyridinyl rings, respectively, indicating a low degree of conjugation between these rings. Intramolecular C—H...N and intermolecular N—H...N hydrogen bonds as well as C—H...π interactions seem to be effective in stabilization of the crystal stru…

(E)-7-(Pyren-1-yl)hept-6-enoic acid

2010

The title compound, C23H20O2, is a precursor of a pyrene-based supramolecular element for non-covalent attachment to a carbon nanotube. The asymmetric unit contains three independent molecules. The carboxylic acid group in each of these molecules serves as an intermolecular hydrogen-bond donor and acceptor, generating the commonly observed double O—H...O hydrogen-bond motif in an eight-membered ring. Weaker C—H...O, π–π [centroid–centroid distance = 3.968 (4) Å] and C—H...π interactions are also found in the crystal structure.

[Pharmacogenomics of antiretrovirals].

2008

HIV infection is a serious but treatable disease, yet current treatment is limited by development of resistance and high rates of adverse drug reactions. Antiretroviral therapy is especially suitable for pharmacogenomic investigation as both drug exposure and treatment response can be reliably measured. Increasing knowledge about genes implicated in pharmacokinetics, mode of action, efficacy, and toxicity of drugs has already provided relevant results for clinical practice, for example: The strong association of the abacavir hypersensitivity reaction with HLA-B*5701 permits testing patients for the allele, and if present avoiding the drug and therefore preventing the reaction. Persons with …
