The S(H)i reaction at silicon – A new entry into cyclic alkoxysilanes

A new mild radical method for the preparation of cyclic five-membered alkoxysilanes is reported. This method comprises an intramolecular homolytic substitution reaction at silicon (S(H)i). Various leaving groups (SiMe3, GeMe3, SnMe3) were tested in the homolytic substitution reaction. We found that high yields were only obtained for silanes bearing a trimethyl-stannyl functionality as leaving group in the S(H)i reaction. Rate constants for the cyclization reaction were estimated by conducting standard competition experiments. Based on the kinetic data, more elaborate reaction sequences such as radical addition reactions with a subsequent S(H)i step were carried out. Stereoselective cyclization reactions were also investigated. Excellent 1,2 diastereoselectivities were observed. The products of the S(H)i reaction, cyclic alkoxysilanes, can easily be converted to the corresponding diol derivatives by Tamao-Fleming oxidation as demonstrated for several examples.

Enantioselective Functionalization of Enamides at the beta-Carbon Center with Indoles

We report an enantioconvergent approach for the functionalization of enamides at the beta-carbon atom, which involves a chiral Br¡ãnsted acid induced tautomerization of 2-amidoallyl into 1-amidoallyl cations. These putative reactive intermediates were produced by ionization of racemic alpha-hydroxy enamides with a chiral Br¡ãnsted acid and captured with substituted indoles in a highly regio- and enantioselective manner.

Design and Characterization of Novel EphA2 Agonists for Targeted Delivery of Chemotherapy to Cancer Cells

Summary The development of novel, targeted delivery agents for anti-cancer therapies requires the design and optimization of potent and selective tumor-targeting agents that are stable and amenable to conjugation with chemotherapeutic drugs. While short peptides represent potentially an excellent platform for these purposes, they often get degraded and are eliminated too rapidly in vivo. In this study, we used a combination of nuclear magnetic resonance-guided structure-activity relationships along with biochemical and cellular studies to derive a novel tumor-homing agent, named 123B9, targeting the EphA2 tyrosine kinase receptor ligand-binding domain. Conjugating 123B9 to the chemotherapeutic drug paclitaxel (PTX) via a stable linker results in an agent that is significantly more effective than the unconjugated drug in both a pancreatic cancer xenograft model and a melanoma lung colonization and metastases model. Hence, 123B9 could represent a promising strategy for the development of novel targeted therapies for cancer.

Manganese-catalyzed synthesis of monofluoroalkenes: Via C-H activation and C-F cleavage

The manganese-catalyzed alpha-fluoroalkenylation of arenes via C-H activation and C-F cleavage has been described. This protocol provides a very useful method for the synthesis of monofluoroalkenes with predominant unconventional E-isomer selectivity which complements the existing strategies for the access to these molecular architectures. In addition, the selectivity of beta-defluorination in the catalytic cycle not only determines the configurations of the products but also obviates the use of external oxidants, providing a good example in the exploitation of manganese-catalyzed redox-neutral C-H transformations.

Determination of eumelanin and pheomelanin in melanomas using solid-phase extraction and high performance liquid chromatography?diode array detection (HPLC-DAD) analysis

Determination of eumelanin and pheomelanin in melanomas that exhibit different pigmentation was carried using a solid-phase extraction (SPE) preparation method based on weak anion exchange chemistry. This extraction significantly enhanced the chromatographic profile obtained by reverse phase high performance liquid chromatography-diode array detection (RP-HPLC-DAD). The SPE method was developed using aqueous standards of melanin markers: thiazole-2,4,5-tricarboxylic acid (TTCA), thiazole-4,5-dicarboxylic acid (TDCA), pyrrole-2,3-dicarboxylic acid (PDCA) and pyrrole-2,3,5-tricarboxylic acid (PTCA) and non-pigmented cell lines spiked with those markers. An excellent average recovery, above 90%, was obtained for the four markers with a relative standard deviation below 7%. We have also optimized the stationary phase and the mobile phase (phosphate concentration and pH) to improve sensitivity and to reduce the analysis time. Elution of the four markers is achieved in 5 min and total analysis of biological samples is completed in 15 min. The quantification limits for TDCA, TTCA, PDCA and PTCA are 60, 50, 47 and 48 ng/mL respectively. Furthermore, DAD detection improves the marker identification in complex matrices through the analysis of UV spectra. We have successfully applied this method to melanoma tumors and cells. Murine B16BL6 tumor are highly pigmented with mostly eumelanin (98.1% of eumelanin) while human SK-MEL-3 tumor contain about 30% pheomelanin. B16BL6 and B16F10 are eumelanic cells lines and NHEM melanocytes contain about 24% of pheomelanin.
