- Synthesis and structure–activity relationship of N-(piperidin-4-yl)benzamide derivatives as activators of hypoxia-inducible factor 1 pathways
-
Guided by bioisosterism and pharmacokinetic parameters, we designed and synthesized a series of novel benzamide derivatives. Preliminary in vitro studies indicated that compounds 10b and 10j show significant inhibitory bioactivity in HepG2 cells (IC50 values of 0.12 and 0.13?μM, respectively). Compounds 10b and 10j induced the expression of HIF-1α protein and downstream target gene p21, and upregulated the expression of cleaved caspase-3 to promote tumor cells apoptosis.

- Discovery of N-{1-[3-(3-Oxo-2,3-dihydrobenzo[1,4]oxazin-4-yl)propyl] piperidin-4-yl}-2-phenylacetamide (Lu AE51090): An allosteric muscarinic M 1 receptor agonist with unprecedented selectivity and procognitive potential
-
The discovery and Structure-activity relationship (SAR) of a series of allosteric muscarinic M1 receptor agonists are described. Compound 17 (Lu AE51090) was identified as a representative compound from the series, based on its high selectivity as an agonist at the muscarinic M1 receptor across a panel of muscarinic receptor subtypes. Furthermore, 17 displayed a high degree of selectivity when tested in a broad panel of G-protein-coupled receptors, ion channels, transporters, and enzymes, and 17 showed an acceptable pharmacokinetic profile and sufficient brain exposure in rodents in order to characterize the compound in vivo. Hence, in a rodent model of learning and memory, 17 reversed delay-induced natural forgetting, suggesting a procognitive potential of 17.

- 4-Aminopiperidine derivatives as a new class of potent cognition enhancing drugs
-
Extrusion of one of the nitrogens of the piperazine ring of potent nootropic drugs previously described gave 4-aminopiperidine analogues that maintained high cognition enhancing activity in the mouse passive avoidance test. One of the new compounds (9, active at 0.01 mg/kg ip) may represent a new lead for the development of cognition enhancers useful to treat the cognitive deficit produced by neurodegenerative pathologies like Alzheimer's disease.
