A copper-catalyzed carbonylative four-component reaction of ethene and aliphatic olefins

To have a balance between reactivity and selectivity has been a long-standing challenge in multicomponent reactions. In this communication, a carbonylative four-component reaction has been developed. With copper as the catalyst, using ethene including other aliphatic alkenes, alcohols and acetonitrile as the substrates under CO pressure, various desired products were produced in moderate to good yields. The obtained products can be applied in the synthesis of delta-valerolactams. Good functional group tolerance and reaction efficiency can be observed here.

Solid lipid particles, particles of bioactive agents and methods for the manufacture and use thereof

The present invention is in the area of administration forms and delivery systems for drugs, vaccines and other biologically active agents. More specifically the invention is related to the preparation of suspensions of colloidal solid lipid particles (SLPs) of predominantly anisometrical shape with the lipid matrix being in a stable polymorphic modification and of suspensions of micron and submicron particles of bioactive agents (PBAs); as well as to the use of such suspensions or the lyophilizates thereof as delivery systems primarily for the parenteral administration of preferably poorly water-soluble bioactive substances, particularly drugs, and to their use in cosmetic, food and agricultural products. SLPs and PBAs are prepared by the following emulsification process: (1) A solid lipid or bioactive agent or a mixture of solid lipids or bioactive agents is melted. (2) Stabilizers are added either to the lipid or bioactive agent and to the aqueous phase or to the aqueous phase only depending on their physicochemical characteristics. (3) Drugs or other bioactive substances to be incorporated into the SLPs may be melted together with the lipids if the physicochemical characteristics of the substance permit or may be dissolved, solubilized or dispersed in the lipid melt before homogenization. (4) The aqueous phase is heated to the temperature of the melt before mixing and may contain for example stabilizers, isotonicity agents, buffering substances, cryoprotectants and/or preservatives. (5) The molten lipid compounds and the bioactive agents are emulsified in an aqueous phase preferably by high-pressure homogenization.

Discovery of cytotoxic and pro-apoptotic compounds against leukemia cells: Tert-butyl-4-[(3-nitrophenoxy) methyl]-2,2-dimethyloxazolidine-3-carboxylate

Aims: We evaluated biological activity in leukemia cells lines of R and S enantiomers of tert-butyl 4-[(3-nitrophenoxy)-methyl]-2,2-dimethyloxazolidine-3- carboxylate (BNDC). Main methods: Cytotoxic activity was assessed by MTT assay. Flow cytometry assays were used to determined DNA fragmentation (Propidium Iodide-PI staining) and phosphatidylserine exposure (Annexin-V and PI staining). DNA condensation was evaluated by fluorescence microscopy using double-staining in leukemia cells (Hoechst and PI). Caspase activities were measured using Z-VAD-FMK, a non-selective caspase inhibitor, by flow cytometry and Z-DEVD-AMC, a selective caspase-3 substrate, by fluorescence spectrometry. Key findings: Both enantiomers displayed cytotoxic activity against leukemia cell lines (HL60, HL60.Bcl-2, HL60.Bcl-XL and Jurkat) with low toxicity against human peripheral blood mononuclear cell – PBMC based on IC50 values. In HL60 cell lines, compounds induce exposure of phosphatidylserine and DNA fragmentation, which could be blocked by pretreatment of cells with Z-VAD-FMK. Confirming this observation, both enantiomers induced caspase-3 activation. Additional analysis revealed an increased percentage of apoptotic cells (defined as those with fragmented nuclei and condensed chromatin) after treatment with compounds. Significance: Taken together, the results indicate that BNDC compounds exhibited cytotoxic and pro-apoptotic activities and have a potential for developing a new class of anticancer drugs.
