Total synthesis and absolute stereochemistry of the proteasome inhibitors cystargolides A and B

The absolute stereochemistry of the cystargolides was determined by total synthesis. Evaluation of synthetic cystargolides and derivatives showed that the natural (2S,3R) stereochemistry is essential for activity. Moreover, benzyl esters (-)-10 and (-)-15 were found to be about 100 times more potent, and to selectively kill MCF-7 cancerous cells.

(Equation presented) Enantiomerically pure 5-acetyl-3-amino-3,4-dihydro-2H- 1-benzopyran and methyl 3-amino-3,4-dihydro-2H-1-benzopyran-5-carboxylate were successfully synthesized starting from D- or L-serine. The formation of the benzopyran ring involved a radical cyclization step. The enantiomeric purities of the final aminochroman derivatives were determined by capillary electrophoresis using beta-cyclodextrins as a chiral selector.

A Synthesis of D-erythro- And L-threo-Sphingosine and Sphinganine Diastereomers via the Biomimetic Precursor 3-Ketosphinganine

The four stereoisomers of sphingosine and sphinganine can be produced in protected form by a short, convergent, biomimetic synthesis from serine. Yields are good (26-38% overall from commercially available serine derivatives), and the stereoselectivities are excellent (>92% de, >95% ee). Several sphingosine L-threo-sphingosine analogues with modified, functionalized tails were prepared to demonstrate the versatility of the method.

N-Carboxy-L-aspartic anhydride benzyl ester

The structure of the title compound, benzyl (1,2,3,4-tetrahydro-2,5-dioxo-1,3-oxazol-4-yl)acetate, C12H11NO5, has been determined in an attempt to explain the polymerization observed in the solid state. The molecules are linked by intermolecular hydrogen bonds between the imino group of the five-membered ring and an adjacent carbonyl O atom, along the c axis. Intramolecular hydrogen bonds are also formed, between the imino group and the carbonyl O atom of the ester group. The five-membered rings are arranged in a layer, sandwiched by layers incorporating the benzyl groups. This structure is thought to be preferable for the polymerization of the compound in the solid state, because the five-membered rings can react with each other in the layer.

Mixed pH-sensitive polymeric micelles for combination drug delivery

Purpose: To prepare mixed polymeric micelles that can carry two different drugs, doxorubicin (DOX) and 17-hydroxyethylamino-17-demethoxygeldanamycin (GDM-OH), for combination cancer chemotherapy. Methods: The pH-sensitive micelles were prepared from poly(ethylene glycol)-poly(aspartate hydrazide) block copolymers to which either DOX or GDM-OH is conjugated through acid-labile hydrazone bond (individual micelles). Mixed micelles were formed not only by simply mixing two different individual micelles in aqueous solutions (aqueous mixed micelles) but also by evaporating organic solvents from the organic/aqueous mixed solvents in which two block copolymers possessing different drugs were dissolved homogeneously (organic mixed micelles). Particle size measurements, pH-dependent drug release tests, cytotoxicity assays and western blot analysis were subsequently conducted. Results: Individual and aqueous/organic mixed micelles showed clinically relevant particle size (<100 nm) and pH-dependent drug release patterns. Mixed polymer micelles suppress cancer cell growth effectively in a drug concentration, mixing method and schedule-dependent way. Conclusion: Combination chemotherapy using polymeric micelles seems to minimize a schedule-dependent change in combination drug efficacy in comparison to drug combination using DMSO formulations. 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.Quality Control of (S)-Benzyl 2-(2,5-dioxooxazolidin-4-yl)acetate, you can also check out more blogs about13590-42-6
