Sigma receptors (SRs) are recognized as valuable targets for the treatment of neurodegenerative disorders. A series of novel SRs ligands were designed by combining key pharmacophoric amines (i.e., benzylpiperidine or benzylpiperazine) with new 1,3-dithiolane-based heterocycles and their bioisosters. The new compounds exhibited a low nanomolar affinity for sigma-1 and sigma-2 receptors. Five selected compounds were evaluated for their neuroprotective capacity on SH-SY5Y neuroblastoma cell line. They were able to counteract the neurotoxicity induced by rotenone, oligomycin and NMDA. Competition studies with PB212, a S1R antagonist, confirmed the involvement of S1R in neuroprotection from the oxidative stress induced by rotenone. Electrophysiological experiments performed on cortical neurons in culture highlighted the compounds ability to reduce NMDA-evoked currents, suggesting a negative allosteric modulator activity toward the NMDA receptor. Altogether these results qualify our novel dithiolane derivatives as potential agents for fighting neurodegeneration.

Paragraph 0072; 0073-0075, (2016/10/09)
The invention provides a double amide derivative containing a sulfur ether and N-sulfur cyano (sulphone) imine structure and replacing pyrazolecarboxamide and a preparing method and purpose thereof, and relates to double amide derivatives containing the pyrazolecarboxamide. The double amide derivative containing the pyrazolecarboxamide has a chemical structure general formula as shown in the map I. The structure general formula and the synthetic method of the double amide derivative and the purpose for being used as insecticides, antiseptics, a plant virus resistance agent and a plant activator are disclosed. The double amide derivative containing the sulfur ether and N-sulfur cayano (sulphone) imine structure and replacing the pyrazolecarboxamide can be mixed with auxiliaries or synergists which are acceptable in agriculture to form a processing technology to be used for preparing the insecticides, the antiseptics, the plant virus resistance agent and the plant activator. The invention further discloses the purpose and preparing method of the double amide derivative containing the sulfur ether and N-sulfur cyano (sulphone) imine structure and replacing the pyrazolecarboxamide combining with commodity insecticides, commodity antiseptics, commodity plant virus resistance agents and commodity plant activators to be used for preventing and curing plant diseases, insect pests, virus diseases in agriculture, forestry and horticulture.

The fast and efficient conversion of epoxides into 2,2-dimethyl-1,3- dioxolanes was studied with catalytic amounts of phosphomolybdic acid (PMA) (0.1-0.2 mol %) at room temperature in solution and under solvent-free conditions. The products were obtained in high to excellent yields within 1-2 min. Copyright Taylor & Francis Group, LLC.
