- Metal-free synthesis of β-aminoketones by the reductive hydroamination of ynones
-
This study describes a cascade method for the synthesis of β-aminoketones through the reductive hydroamination of alkynes under very mild metal-free conditions. It allows for the rapid conversion of ynones and amines into corresponding β-aminoketones with a broad substrate scope and diverse functionalities. This straightforward and easy-to-handle reaction process can be successfully applied for the synthesis of Proroxan and Propipocaine, offering a potential option for the synthesis of drug molecules with the β-aminoketone skeleton.

- Design, synthesis and biological evaluation of novel triaryldimethylaminobutan-2-ol derivatives against Mycobacterium tuberculosis
-
Bedaquiline (TMC207), a typical diarylquinoline anti-tuberculosis drug, has been approved by FDA to specifically treat MDR-TB. Herein we describe design, synthesis, and in vitro biological evaluation against Mycobacterium tuberculosis of a series of triaryldimethylaminobutan-2-ol derivatives obtaining from the structural modification of TMC207. Compounds 23, 25, 28, 32, 39 and 43 provided superior anti-mycobacterial activity than positive control PC01 which shows the same configuration and contains TMC207. Compounds 16, 20, 29, 34, 37, 45 and 47 exhibited the similar activity to positive control PC01. Most importantly, the series of compounds showed excellent activity against XDR-Mtb. The result of acute toxicity suggested that this class of triaryldimethylaminobutan-2-ol derivatives should be graded as low. Further SAR analysis indicates that a large steric bulk of triaryl and 7-Br, 3-OCH3 on 1-naphthyl are critical.

- Optimization of isochromanone based urotensin II receptor agonists
-
A series of novel isochromanone based urotensin II receptor agonists have been synthesized and evaluated for their activity using a functional cell based assay (R-SAT). Several potent and efficacious derivatives were identified with 3-(3,4-dichlorophenyl)-6,7-dimethyl-3-(2-dimethylaminoethyl)isochroman-1-one (28) being the most potent compound showing an EC50-value of 51 nM, thereby being the most potent compound so far within the isochromanone series. In addition, two other heterocyclic systems (isochromanes and tetrahydroisoquinolinones) were investigated and these derivatives were found to be both potent and efficacious. The activity of the isochromane derivatives implies that the carbonyl group of the isochromanone is not necessary for activity. Furthermore it was found that the geometry of the heterocycles was more important for receptor interaction than the composition of the heteroatoms present.

- Further exploration of 1-{2-[Bis-(4-fluorophenyl)methoxy]ethyl}piperazine (GBR 12909): Role of N-aromatic, N-heteroaromatic, and 3-oxygenated N-phenylpropyl substituents on affinity for the dopamine and serotonin transporter
-
A series of N-aromatic, N-heteroaromatic, and oxygenated N-phenylpropyl derivatives of 1-(2-benzhydryloxyethyl)-piperazine and 1-{2-[bis-(4-fluorophenyl)methoxy]ethyl}piperazine, analogues of GBR 12909 (1a) and 12935 (1b), was synthesized and examined for their dopamine (DAT) and serotonin (SERT) transporter binding properties. One of these compounds, racemic 3-[4-(2-benzhydryloxyethyl)piperazin-1-yl]-1-(3-fluorophenyl)-propan-1-ol (33), had DAT affinity as good as, or better than, GBR 12909 and 12935, and was more selective for DAT over SERT than the GBR compounds. Both trans- (43) and cis- (47) (±)-2-(4-{2-[bis-(4-fluorophenyl)-methoxy]ethyl}piperazin-1- ylmethyl)-6-methoxy-1,2,3,4-tetrahydronaphthalen-1-ol had relatively good SERT selectivity and, as well, showed high affinity for SERT.
