Interaction of doxorubicin hydrochloride in the presence of, mixed aggregate of ibuprofen sodium and cationic lipid

This research was highlighted the importance of mixed aggregates based on drug-lipid to improve the interaction of one or more drugs in aqueous medium. This mixed aggregate can significantly inhibit the growth of MCF-7 cells, and has great potential for anti-inflammatory and cancer treatment after tumor removal. The cationic lipid (CL) has been synthesized with multistep reaction and is characterized by 1H NMR and mass spectroscopy. CL and ibuprofen (IBF) physiochemical analysis was investigated using surface tension, conductance, dynamic light scattering (DLS), and electron microscope transmission (TEM). The strong synergism between mixed aggregate (LIB) system CL and IBF was observed. The study on UV spectroscopy measured that the LIB mixed aggregate showed optimum binding to doxorubicin hydrochloride (DOX) and the binding constant Log Kb was 6.17 compared to single CL, the Log Kb was 5.83. Binding results indicated that the DOX was more encapsulated in mixed LIB aggregates compared to single CL aggregates. This mixed aggregate LIB has excellent performance in controlling the release of drugs. For single CL aggregate, approximately 62.5percent DOX was released after 72 h (pH = 7.4). However, LIB such as, (0.1αCL+ 0.9αIBF), the release of DOX decreased to 16.08percent. Finally, LIB mixed aggregate applicability has been used to minimize the cytotoxicity of MCF-7 cells, and it has been found that DOX in LIB mixed aggregates has a higher inhibitory effect on cell growth than DOX in CL.

Use of quaternary polysiloxanes in cleaning and care compositions

The invention relates to the use of polysiloxanes which comprise a plurality of quaternary ammonium groups in the molecule in cosmetic or pharmaceutical compositions for the cleaning and care of keratin fibers, in particular of human hair. The improvement in the shine and in the color protection of the hair is achieved if the polysiloxanes are used in an amount in the range from 0.01 to 30%.

Synthesis of carbamate-linked lipids for gene delivery

Series of lipids 1a-d and 2a,b, with carbamate linkages between hydrocarbon chains and ammonium or tertiary amine head, which were pH sensitive, were synthesized for liposome-mediated gene delivery. The variable length of carbon chains and quaternary ammonium or neutral tertiary amine heads allowed to find the structure-function relationship of how these factors affect cationic lipids on gene delivery performance.

Process for the preparation of glyceraldehyde and derivatives thereof

The invention pertains to a process for the preparation of glyceraldehyde, or an acetal or a hemiacetal thereof, characterized in that 3-butene-1,2-diol is dissolved in a lower alkanol and is subjected to ozonolysis to obtain a 3-hydroperoxy-3-alkoxy-propane-1,2-diol, which is subjected to a reductive treatment to obtain a hemiacetal of glyceraldehyde, which optionally may be converted into glyceraldehyde or an acetal or hemiacetal thereof, and to a process wherein the hemiacetal of glyceraldehyde is converted to a 3-aminopropane-1,2-diol derivative, by subjecting the hemiacetal of glyceraldehyde to a reductive treatment in the presence of ammonia or a primary or secondary amine. Preferably, the hemiacetal of glyceraldehyde is subjected to a reductive treatment in the presence of an amine with the formula R1R2NH, wherein R1 and R2 independently are hydrogen or an alkyl group with 1-18 carbon atoms, or R1 and R2 together with the nitrogen atom to which they are bonded form a 5- or 6-membered ring, to give a compound with the formula R1R2N—CH2—CHOH—CH2OH, wherein R1 and R2 have the previously given meanings

Synthesis, redox and electrochemical properties of new anthraquinone- attached micelle- and vesicle-forming cationic amphiphiles

Three new cationic amphiphiles bearing anthraquinone moieties at the polar headgroup region were synthesized. The single-chain amphiphile, N,N-dimethyl-N-octadecyl-N-(9,10-dihydro-9,10-dioxoanthracen-2-ylmethyl) ammonium bromide 1, in the presence of cetyltrimethylammonium bromide upon dispersion in water gave co-micellar aggregates containing covalently attached anthraquinone residues at the polar aqueous interfaces. The other two double-chain amphiphiles, N,N-dioctadecyl-N-methyl-N-(9,10-dihydro-9,10- dioxoanthracen-2-ylmethyl)ammoniurn bromide 2 and N,N-dimethyl-N-(1,2- bispalmitoyloxypropanyl)-N-(9,10-dihydro-9110-dioxanthracen-2-ylmethyl)ammonium bromide 3, however, on dispersion in aqueous media produced vesicular aggregates. The critical temperatures for the gel to liquid-crystalline-like phase transition processes for the vesicular systems were determined by following temperature-dependent changes in the ratios of keto-enol tautomeric forms of benzoylacetanilide doped within respective vesicular assemblies. The redox chemistry of the these supramolecular assemblies was also studied by following the time-dependent changes in the UV-VIS absorption spectroscopy in the presence of exogenous reducing or oxidizing agents. Electrochemical studies using glassy carbon electrodes reveal that redox-active amphiphiles adsorb on to the glassy carbon surfaces to form electroactive deposits when dipped into aqueous suspensions of either of these aggregates irrespective of the micellar or vesicular nature of the dispersions.
