  • Patent number: 11857520
    Abstract: A nasal spray formulation and a method of using a locally acting sodium channel blocker to treat pain is disclosed, wherein the nasal spray formulation comprises from about 5% to about 30% w/v of a locally active sodium channel blocker, from about 0.25% to about 5% w/v of a buffering agent, and from about 5 to about 99% w/v of a pharmaceutically acceptable carrier for nasal administration. The nasal spray formulation is preferably contained in a mechanical multi-dose pump which sprays a unit dose of the nasal spray formulation with a wide plume and small droplet size, such that the unit dose is administered by actuating the mechanical multi-dose spray pump device and spraying a volume of the nasal spray formulation into each nostril of a human subject. Preferably, the nasal spray formulation does not include a preservative.

  • Patent number: 9676679
    Abstract: The present disclosure is directed to a traceless directing group in a radical cascade. The chemo- and regioselectivity of the initial attack in skipped oligoalkynes is controlled by a propargyl alkoxy moiety. Radical translocations lead to the boomerang return of radical center to the site of initial attack where it assists to the elimination of the directing functionality via ?-scission in the last step of the cascade. In some aspects, the reaction of the present invention is catalyzed by a stannane moiety, which allows further via facile reactions with electrophiles as well as Stille and Suzuki cross-coupling reactions. This selective radical transformation opens a new approach for the controlled transformation of skipped oligoalkynes into polycyclic ribbons of tunable dimensions.
