4-aroylpiperidines and 4-(alpha-hydroxyphenyl)piperidines as selective sigma-1 receptor ligands: Synthesis, preliminary pharmacological evaluation and computational studies

Background: Sigma (sigma) receptors are membrane-bound proteins characterised by an unusual promiscuous ability to bind a wide variety of drugs and their high affinity for typical neuroleptic drugs, such as haloperidol, and their potential as alternative targets for antipsychotic agents. Sigma receptors display diverse biological activities and represent potential fruitful targets for therapeutic development in combating many human diseases. Therefore, they present an interesting avenue for further exploration. It was our goal to evaluate the potential of ring opened spipethiane (1) analogues as functional ligands (agonists) for sigma receptors by chemical modification. Results: Chemical modification of the core structure of the lead compound, (1), by replacement of the sulphur atom with a carbonyl group, hydroxyl group and 3-bromobenzylamine with the simultaneous presence of 4-fluorobenzoyl replacing the spirofusion afforded novel potent sigma-1 receptor ligands 7a-f, 8a-f and 9d-e. The sigma-1 receptor affinities of 7e, 8a and 8f were slightly lower than that of 1 and their selectivities for this receptor two to threefold greater than that of 1. Conclusions: It was found that these compounds have higher selectivities for sigma-1 receptors compared to 1. Quantitatitive structure-activity relationship studies revealed that sigma-1 binding is driven by hydrophobic interactions. Graphical abstract Identified pharmacophore features for sigma binding.

The influence of lateral substituents on the mesophase behaviour of banana-shaped mesogens. Part II

New materials are presented, derived from the original banana compounds where the first smectic phases with polar switching (SmCP) were detected. Our results demonstrate that the introduction of lateral substituents on the central ring (F, Cl, CN, NO2, CH3) and/or on the terminal rings (Cl, Br, CH3) can significantly change the mesophase behaviour. The influence of such substituents is much more pronounced than in comparable calamitic compounds. The clearing temperatures are more or less depressed depending on the number, position and type of lateral substituents. In most cases the laterally substituted compounds form SmCPA phases. Of basic and theoretical interest are compounds where substituents (e.g. 4-cyano; 4,6-dichloro) on the central core enhance the bending angle giving rise to polymorphism variants with conventional smectic and nematic phases as well as “banana phases”: N-SmCPA; SmA-SmCPA; SmA-SmC-SmCPA; SmA-SmAPA-SmCPA. The last mentioned phase sequence has not been reported for single compounds up to now. Furthermore, the pool of materials allows us to compare the significant influence of lateral halogen atoms F, Cl, Br on the mesophase behaviour of bent-core mesogens for the first time. Nevertheless, up to now it has not been possible to predict the mesophase behaviour of bent core mesogens on the basis of the molecular architecture. The Royal Society of Chemistry 2005.

SnAP reagents for the synthesis of piperazines and morpholines

Substituted piperazines and morpholines are valuable structural motifs in biologically active compounds, but are not easily prepared by contemporary cross-coupling approaches. In this report, we introduce SnAP reagents for the transformation of aldehydes into N-unprotected piperazines and morpholines. This approach offers simple, mild conditions compatible with aromatic, heteroaromatic, aliphatic, and glyoxylic aldehydes and provides mono- and disubstituted N-heterocycles in a single step.

Cytotoxic activity and DNA binding property of new aminopyrimidine derivatives

Background: Chromene and anilinopyrimidine heterocyclics are attractive anticancer compounds that have inspired many researchers to design novel derivatives bearing improved an-ticancer activity. Method: A series of pyrimidine-fused benzo[f]chromene derivatives 6a-x were synthesized as an-ticancer hybrids of 1H-benzo[f]chromenes and anilinopyrimidines. The inhibitory activity of the synthesized compounds 6a-x against cell viability of human chronic myelogenous leukemia (K562), human acute lymphoblastic leukemia (MOLT-4) and human breast adenocarcinoma (MCF-7) cell lines was evaluated using MTT assay. The interaction of the most promising compound with calf-thymus DNA was also studied using spectrometric titrations and Circular Dichro-ism (CD) spectroscopy. Results: Most compounds showed promising activity against tested cell lines. Among them, 2,4-dimethoxyanilino derivative 6g exhibited the best profile of activity against tested cell lines (IC50s = 1.6-6.1 muM) with no toxicity against NIH3T3 normal cell (IC50 >200 muM). The spectro-metric studies exhibited that compound 6g binds to DNA strongly and may change DNA conformation significantly, presumably via a groove binding mechanism. Conclusion: The results of this study suggest that the prototype compound 6g can be considered as a novel lead compound for the design and discovery of novel anticancer agents.
