  New Adamantane Phenylalkylamines with σ-Receptor Binding Affinity and Anticancer Activity, Associated with Putative Antagonism of Neuropathic Pain

  摘要：

  The synthesis of:the adamantane phenylalkylamines 2a-d, 3a-c, and 4a-e is described These compounds exhibited significant antiproliferative activity, in vitro, against eight cancer cell lines tested The sigma(1), sigma(2). and Sodium channel binding affinities of compounds 2a, 3a, 4a, and 4c-e were investigated The most interesting analogue, 4a, exhibited significant in vivo anticancer profile on, pancreas, prostate, leukemia, and ovarian cancer cell line Xenografts.-together with,apoptosis and caspase-3 activation. Inhibition of the Cancer cells cycle at the sub-G1 level was also Obtained with 4a. Finally, encouraging results were observed With 4a in vivo on mice, suggesting putative antimetastatic and analgesic activities of this compound.

  Reactions of difluorocarbene with benzyl and alkylzinc halides leading to fluorinated organozinc species have been described. The generated α-difluorinated organozinc reagents are reasonably stable in solution and can be quenched with external electrophiles (iodine, bromine, proton), affording compounds containing the CF2 fragment.

  methodology for the C(sp3)−C(sp3) functionalisation of saturated N-heterocyclic systems is disclosed. First, aminal derivatives are generated through the anodic oxidation of readily accessible carboxylic acids. Then, in the presence of BF3 ⋅ OEt2, iminium ions are unmasked and rapidly alkylated by organozinc reagents under flow conditions. Secondary, tertiary and quaternary carbon centers have been successfully

  quaternary carbons is a key challenge in organic and medicinal chemistry. We report a cobalt-catalyzed C(sp3)–C(sp3) cross-coupling that allows for the introduction of benzyl, heteroarylmethylzinc and allyl groups to halo-carbonyl substrates. The cross-coupling reaction is selective for C(sp3)-over C(sp2)-halides, in contrast to most used catalytic metals, and allows access to novel scaffolds of pharmaceutical
