Non-biomimetic route to deoxyadenosine adducts of carcinogenic polycyclic aromatic hydrocarbons
(Elsevier, 1991-10-21)
Aminotriols are prepared by direct aminolysis of the diol epoxides of polycyclic aromatic hydrocarbons, providing a substantial improvement over literature methods. The condensation of aminotriols with 6-halopurine ...
The measurement of molecular diversity by receptor site interaction simulation
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-09)
The assembly of large compound libraries for the purpose of screening against various receptor targets to identify chemical leads for drug discovery programs has created a need for methods to measure the molecular diversity ...
Complementarity of Δ opioid ligand pharmacophore and receptor models
(John Wiley & Sons, Inc., 1999)
The elaboration of a pharmacophore model for the Δ opioid receptor selective ligand JOM-13 (Tyr–c[ D -Cys–Phe– D -Pen]OH) and the parallel, independent development of a structural model of the Δ receptor are summarized. ...
Objective models for steroid binding sites of human globulins
(Kluwer Academic Publishers; Springer Science+Business Media, 1997-01)
We report the application of a recently developed alignment-free 3D QSAR method [Crippen,G.M., J. Comput. Chem., 16 (1995) 486] to a benchmark-type problem. The test systeminvolves the binding of 31 steroid compounds to ...
Determination of an empirical energy function for protein conformational analysis by energy embedding
(John Wiley & Sons, Inc., 1987-10)
It is quite easy to propose an empirical potential for conformational analysis such that given crystal structures lie near local minima. What is much more difficult, is to devise a function such that the native structure ...
Microscale sample deposition onto hydrophobic target plates for trace level detection of neuropeptides in brain tissue by MALDI-MS
(John Wiley & Sons, Ltd., 2005-10)
A sample preparation method that combines a modified target plate with a nanoscale reversed-phase column (nanocolumn) was developed for detection of neuropeptides by matrix-assisted laser desorption/ionization time-of-flight ...
Discriminative stimulus effects of a centrally administered, delta-opioid peptide ( d -Pen 2 - d -Pen 5 -enkephalin) in pigeons
(Springer-Verlag, 1996-10)
The present study assessed the discriminative stimulus effects of the delta-opioid agonist [ d -Pen 2 - d -Pen 5 ]enkephalin (DPDPE) in pigeons. Food-restricted pigeons were trained to discriminate between ICV injections ...
A potential function for protein folding
(Kluwer Academic Publishers; J. C. Baltzer AG, Scientific Publishing Company ; Springer Science+Business Media, 1991-12)
One of the most difficult problems in computational chemistry is the prediction of the three-dimensional structure of a protein molecule given only its amino acid sequence. Although there are several programs for calculating ...
