Preparation of α-aryl acetophenones from styryl ethers and aryldiazonium salts is described. The reaction is catalyzed by palladium acetate at room temperature in the absence of ligand and base. The developed method is highly attractive in terms of reaction conditions, substrate scope, functional group tolerance and yields. Synthetic applications of the present method are demonstrated by preparing α-aryl indoles and 3-aryl isocoumarin from styryl ethers.

A series of (E)-1,2-diarylethylidenehydrazine carboximidamides 2a–j were synthesized and characterized by NOESY experiment as anticonvulsant agents and their antiseizure activity was evaluated by intracerebroventricular administration of compounds. Most of the compounds had significant protection against tonic-clonic seizures and 2a was found to be as equipotent as carbamazepine in seizures control. In order to find their anticonvulsant mechanism of action, 2a was subjected to further electrophysiological studies using patch-clamp technique. The results confirmed that this compound is neither a voltage-gated sodium channel blocker nor a NMDA/AMPA antagonist. Although 2a did not show any direct GABA agonistic activity, it could decrease EPSP and increase IPSP frequency without any change in amplitude. Finally, the results indicated most likely a presynaptic GABA-mediated mechanism of 2a for its antiseizure activity such as inhibition of the GABA-T which was validated by molecular docking.

In order to find novel cyclooxygenase (COX)-2 inhibitors for treating inflammatory-based diseases such as Alzheimer's disease (AD), an ethyl carboxylate side chain was added to 5-(4-chlorophenyl)-6-(4-(methylsulfonyl)phenyl)-3-(methylthio)-1,2,4-triazine

The treatment of Human African trypanosomiasis remains a major unmet health need in sub-Saharan Africa. Approaches involving new molecular targets are important; pteridine reductase 1 (PTR1), an enzyme that reduces dihydrobiopterin in Trypanosoma spp., has been identified as a candidate target, and it has been shown previously that substituted pyrrolo[2,3-d]pyrimidines are inhibitors of PTR1 from Trypanosoma brucei (J. Med. Chem. 2010, 53, 221-229). In this study, 61 new pyrrolo[2,3-d]pyrimidines have been prepared, designed with input from new crystal structures of 23 of these compounds complexed with PTR1, and evaluated in screens for enzyme inhibitory activity against PTR1 and in vitro antitrypanosomal activity. Eight compounds were sufficiently active in both screens to take forward to in vivo evaluation. Thus, although evidence for trypanocidal activity in a stage I disease model in mice was obtained, the compounds were too toxic to mice for further development.

A series of combretastatin A-4 analogs in which cis-olefinic bond replaced by thiazole ring were prepared by reaction of α-bromo-1,2-(p-substituted) diaryl-1-ethanones and dithiocarbamate derivatives. The cytotoxicity of these compounds was determined against three cancer cell lines (HT-29), (MCF-7), (AGS) as well as fibroblastic cell line (NIH-3T3) using MTT assay. Inhibition of tubulin polymerization for some potent compounds was evaluated. These biological studies proved that 6j and 6o were the most potent compounds in this series. Furthermore 2-(methylthio)-substituted compounds show moderate or no activity. Docking studies involving 6j and 6o demonstrated that this analogs could be successfully docked in the colchicine binding site of α,β-tubulin.
