- Novel 3-(1H-indol-3-yl)-2-[3-(4-methoxyphenyl)ureido]propanamides as selective agonists of human formyl-peptide receptor 2
-
N-Formyl peptide receptors (FPRs) are G protein-coupled receptors (GPCRs) that play critical roles in inflammatory reactions, and FPR-specific interactions can possibly be used to facilitate the resolution of pathological inflammatory reactions. We here report the synthesis and biological evaluation of six pairs of chiral ureidopropanamido derivatives as potent and selective formyl peptide receptor-2 (FPR2) agonists that were designed starting from our lead agonist (S)-3-(1H-indol-3-yl)-2-[3-(4-methoxyphenyl)ureido]-N-[[1-(5-methoxy-2-pyridinyl)cyclohexyl]methyl]propanamide ((S)-9a). The new compounds were obtained in overall yields considerably higher than (S)-9a. Several of the new compounds showed agonist properties comparable to that of (S)-9a along with higher selectivity over FPR1. Molecular modeling was used to define chiral recognition by FPR2. In vitro metabolic stability of selected compounds was also assessed to obtain preliminary insight on drug-like properties of this class of compounds.

- Fe-catalyzed regiodivergent [1,2]-shift of α-aryl aldehydes
-
An Fe-catalyzed conversion of aldehydes to ketones via [1,2]-shift has been developed. This skeletal rearrangement shows a wide substrate scope and chemoselectivity profile while exhibiting an excellent [1,2]-aryl or [1,2]-alkyl shift selectivity that is easily switched by electronic effects.

- Synthesis and pharmacological evaluation of 1-alkyl-N-[2-ethyl-2-(4- fluorophenyl)butyl]piperidine-4-carboxamide derivatives as novel antihypertensive agents
-
We synthesized and evaluated inhibitory activity against T-type Ca 2+ channels for a series of 1-alkyl-N-[2-ethyl-2-(4-fluorophenyl) butyl]piperidine-4-carboxamide derivatives. Structure-activity relationship studies have revealed that dialkyl substituents at the benzylic position play an important role in increasing inhibitory activity. Oral administration of N-[2-ethyl-2-(4-fluorophenyl)butyl]-1-(2-phenylethyl)piperidine-4-carboxamide (20d) lowered blood pressure in spontaneously hypertensive rats without inducing reflex tachycardia, which is often caused by traditional L-type Ca2+ channel blockers.

- Discovery of N-methyl-1-(1-phenylcyclohexyl)methanamine, a novel triple serotonin, norepinephrine, and dopamine reuptake inhibitor
-
The current work discloses a novel cyclohexylarylamine chemotype with potent inhibition of the serotonin, norepinephrine, and dopamine transporters and potential for treatment of major depressive disorder. Optimized compounds 1 (SERT, NET, DAT, IC50 = 169, 85, 21 nM) and 42 (SERT, NET, DAT IC50 = 34, 295, 90 nM) were highly brain penetrant, active in vivo in the mouse tail suspension test at 30 mpk po and were not general motor stimulants.
