- Design and Synthesis of Novel Triazolyl Benzoxazine Derivatives and Evaluation of Their Antiproliferative and Antibacterial Activity
-
A series of novel triazolyl benzoxazine derivatives have been synthesized via Cu(I)-catalyzed ‘Click’ cycloaddition. All of the compounds were fully characterized from their spectral data, and their antiproliferative activity was evaluated against three selected human cancer cell lines: cervical cancer cells (HeLa), colorectal adenocarcinoma (HT-29), and ovarian adenocarcinoma (SKOV-3). A few representative compounds have also been evaluated for their antibacterial potential against two bacterial strains Pseudomonas aeruginosa and Bacillus subtilis.

- Synthesis, structure-activity relationships, and biological properties of 1-heteroaryl-4-[ω-(1H-indol-3-yl)alkyl]piperazines, novel potential antipsychotics combining potent dopamine D2 receptor antagonism with potent serotonin reuptake inhibition
-
A series of novel bicyclic 1-heteroaryl-4-[ω-(1H-indol-3-yl)alkyl] piperazines was synthesized and evaluated on binding to dopamine D2 receptors and serotonin reuptake sites. This class of compounds proved to be potent in vitro dopamine D2 receptor antagonists and in addition were highly active as serotonin reuptake inhibitors. Some key representatives showed potent pharmacological in vivo activities after oral dosing in both the antagonism of apomorphine-induced climbing and the potentiation of 5-HTP-induced behavior in mice. On the basis of the preclinical data, 8-{4-[3-(5-fluoro-1H- indol-3-yl)propyl]piperazin-1-yl}-4H-benzo[1,4]oxazin-(R)-2-methyl-3-one (45c, SLV314) was selected for clinical development. In vitro and in vivo studies revealed that 45c has favorable pharmacokinetic properties and a high CNS plasma ratio. Molecular modeling studies showed that the bifunctional activity of 45c can be explained by its ability to adopt two different conformations fitting either the dopamine D2 receptor pharmacophore or the serotonin transporter pharmacophore.
