Identification of novel scaffolds for potential anti- Helicobacter pylori agents based on the crystal structure of H. pylori 3-deoxy- d -manno-octulosonate 8-phosphate synthase (Hp KDO8PS)

The crystal structure of 3-deoxy-d-manno-octulosonate-8-phosphate synthase (KDO8PS) from Helicobacter pylori (HpKDO8PS) was determined alone and within various complexes, revealing an extra helix (HE) that is absent in the structures of KDO8PS from other

Structure-activity relationship studies of novel 4-[2-[bis(4- fluorophenyl)methoxy]ethyl]-1-(3-phenylpropyl)piperidine analogs: Synthesis and biological evaluation at the dopamine and serotonin transporter sites

Several analogs of the potent dopamine (DA) transporter ligand 4-[2- [bis(4-fluorophenyl)-methoxy]ethyl]-1-(3-phenylpropyl)piperidine, 1b, were made and biologically evaluated for their binding at the DA and serotonin (5HT) transporters in rat striatal membranes. Different alkyl chain lengths and substitutions were introduced in these molecules to generate an optimum activity and selectivity for the DA transporter. In general, unsubstituted and fluoro-substituted compounds were the most active and selective for the DA transporter. The compound 4-[2(diphenylmethoxy)ethyl]-1-benzylpiperidine, 9a, showed high potency and was the most selective for the DA transporter (5HT/DA = 49) in this series of compounds. Some of these novel analogs were found to be more selective in binding at the DA transporter than the original GBR 12909 molecule, 1-[2-[bis(4-fluorophenyl)methoxy]ethyl]-4-(3- phenylpropyl)piperidine.

Synthesis and pharmacological evaluation of a new class of 2-oxo-8- azaspiro (4,5)decan-1-ones as analogues of the muscarinic agonist RS-86

A new series of 8-substituted-2-oxo-8-azapsiro (4,5)decan-1-ones has been synthesized and compounds tested for their cholinergic properties in comparison with the muscarinic agonist RS-86. Preliminary in vitro and in vivo pharmacological data indicate that none of them is provided with significant cholinergic effects either at central or peripheral level. A possible explanation for the lack of activity is given on the basis of conformational studies.

Novel piperidine σ receptor ligands as potential antipsychotic drugs

σ receptor ligands represent a new class of potential antipsychotic drugs. This paper presents the structure-activity relationships leading to novel disubstituted piperidine σ ligands, which have little or no affinity for dopamine D2 receptors. Selectivity for σ sites over dopamine D2 or serotonin 5-HT2 receptors appears to be governed by the chemical nature of the piperidine nitrogen substituent, its distance from the basic nitrogen, and its orientation relative to the other piperidine substituent. Several of these compounds have good oral potency in some animal models used to evaluate potential antipsychotic drugs. The N-cyclopropylmethyl ketones and ethers (e.g. 6i (DuP 734), 6q, 18a, and 18n) have the best in vivo potency. Compounds 6i (DuP 734) and 6q did not cause catalepsy in the rat, even at very high doses. On the basis of the pharmacology profiles of these σ ligands, we propose these compounds may be effective antipsychotic drugs, which do not induce extrapyramidal side effects or tardive dyskinesia.
