By further optimizing compound A [2′-fluoro-N-methyl-[1,1′-biphenyl]-2-sulfonamide], we identified DSP-0565 [2-(2′-fluoro-[1,1′-biphenyl]-2-yl)acetamide, 17a] as a strong, broad-spectrum anti-epileptic drug (AED) candidate. Our efforts mainly focused on finding an alternative polar group for the sulfonamide in order to improve ADME profile of compound A including good metabolic stability and no reactive metabolic production. This led to the identification of biphenyl acetamide as a new scaffold for development of broad-spectrum AED candidates. DSP-0565 showed anti-convulsant activity in various models (scPTZ, MES, 6 Hz and amygdala kindling) with good safety margin, and was therefore selected as a clinical candidate.
Magnetic nanoparticles as an orthogonal support of polymer resins: Applications to solid-phase Suzuki cross-coupling reactions

Most of the reactants immobilized on conventional solid-phase resins are buried inside the interiors of lightly cross-linked polystyrene beads. An orthogonal support of solid-phase resins needs to be small enough to penetrate the interpolymeric chain spaces of a swollen resin to reach reaction sites. In this paper, we report the use of magnetic nanoparticles (~4 nm) as an orthogonal matrix to assist solid-phase reactions. A magnetic nanoparticle-supported homogeneous Pd catalyst was employed for promoting the Suzuki cross-coupling of an aryl halide on resins and an excessive arylboronic acid in solution. The workup separating three components (the catalyst, product, and remaining arylborate) is a chromatography-free process. The Pd catalyst was magnetically isolated and recycled from the reaction mixture by applying an external magnetic field. Then, a filtration process was followed to recover the excess borate reagent from the resins/product. Our work here presents the first example of an orthogonal matrix of solid-phase resins and shows the promise of employing nanomaterials in organic synthesis.

The synthesis of cepharadione-B and 2-demethoxy analogues is described. Starting from fluorenones, ring C was formed by cyclization of (biphenyl-2-yl)acetyl morpholines under Bischler-Napieralsky conditions. The photochemistry of chloroacetamides was used to form ring B. The cytotoxicity of these compounds on several tumor cell lines was evaluated.
