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.

Copper salt-catalyzed azide-[3 + 2] cycloadditions of ynamides and bis-ynamides

A one-pot synthesis of amide-substituted triazoles from alkyl bromides and ynamides is described here along with syntheses of novel bis-ynamidesand their applications in [3 + 2] cycloadditions with azides to construct unique bis-triazoles.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 102029-44-7, you can also check out more blogs about102029-44-7

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.

Predictable and regioselective insertion of internal unsymmetrical alkynes in rhodium-catalyzed cycloadditions with alkenyl isocyanates

A regioselective, rhodium-catalyzed cycloaddition between a variety of internal, unsymmetrical alkynes is described. We document the impact of both steric and electronic properties of the alkyne on reaction course, efficiency, and enantioselectivity. The substituent that better stabilizes a positive charge or the larger group, all else being equal, inserts distal to the carbonyl moiety in a predictable and controllable fashion. The reaction scope is broad and the enantioselectivities are high, providing an “instruction manual” for substrate choice when utilizing this reaction as a synthetic tool.

Synthesis of azachrysenes and multi-nitrogenated derivatives

Azachrysenes are aromatic tetracyclic structures where one carbon atom is replaced by nitrogen in any symmetrically distinct position of the fused aromatic ring. They can be considered analogs of azasteroids, with recognized potential as drug candidates. The present review surveys the work carried out over the last three decades on the synthesis of mono-, di-, tri- and penta-azachryzene derivatives. Although a diversity of synthetic approaches were described in the literature, there are no recent review articles on this subject.

KCC-1 Supported Ruthenium-Salen-Bridged Ionic Networks as a Reusable Catalyst for the Cycloaddition of Propargylic Amines and CO2

Abstract: This study investigates the potential application of an efficient, easily recoverable and reusable KCC-1 nanoparticle-supported Salen/Ru(II) catalyst in the synthesis of 2-oxazolidinones from CO2, and propargylic amines. The KCC-1/Salen/Ru(II) NPs were thoroughly characterized by using TEM, SEM, TGA, FT-IR, ICP-MS, and BET. This observation was exploited in the direct and selective chemical fixation of CO2, affording high degrees of CO2 capture and conversion. The recycled catalyst has been analyzed by ICP-MS showing only minor changes in the morphology after the reaction, thus confirming the robustness of the catalyst.

Studies toward asymmetric synthesis of leiodelide A

An enantioselective route for oxazoline 4, a key fragment toward the asymmetric synthesis of leiodelide A, is described. We synthesized northern subunit 6 through a Julia-Lythgoe olefination and subsequent Sharpless asymmetric dihydroxylation. Moreover, a highly diastereoselective method using well-established Evans’ asymmetric aldol condensation was developed for preparation of southern fragment 5. The additional feature of this synthetic route is the formation of oxazoline 4 through DAST-promoted cyclization of the amidation product from subunits 5 and 6.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Product Details of 122709-21-1, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 122709-21-1, in my other articles.

Delta4-Oxazolin-2-ones and process therefor

Compounds having the formula STR1 wherein R is hydrogen or an acyl radical are prepared by chlorinating 3-acyl-oxazolidin-2-ones, followed by dehydrochlorination and optionally by saponification and reacylation. The compounds are useful as starting material for substitution and addition reactions and as vinyl monomers in homo- and copolymerizations, whereby oxazolidin-2-one rings containing polymers are formed. These polymers can be used as antistatic agents, dyeing auxiliaries and ion exchangers.
