  • Patent number: 6323201
    Abstract: Novel, heterocyclic compounds having at least one ring nitrogen, disclosed side chains and, in some embodiments, an oxygen ortho to the ring nitrogen inhibit inflammatory responses associated with TNF-&agr; and fibroblast proliferation in vivo and in vitro. The compounds of the invention neither appreciably inhibit the activity of cAMP phosphodiesterase nor the hydrolysis of phosphatidic acid, and are neither cytotoxic nor cytostatic. Preferred compounds of the invention are esters. Methods for the use of the novel compounds to inhibit ceramide-mediated intracellular responses in stimuli in vivo (particularly TN-&agr;) are also described. The methods are expected to be of use in reducing inflammatory responses (for example, after angioplasty), in limiting fibrosis (for example, of the liver in cirrhosis), in inhibiting cell senescence, cell apoptosis and UV induced cutaneous immune suppression.

  • Patent number: 6310204
    Abstract: Calculated performance improvements are expected from a particularly new class of compounds, geminal-bis(difluoramino)-substituted heterocyclic nitramines, when formulated into explosives and propellants. This invention involves novel and nonintuitive methods for the preparation of certain derivatives of 2,2-bis(difluoramino)-N-nitro-1,3-propanediamine which are suitable precursors leading to 5,5-bis(difluoramino)hexahydro-1,3-dinitropyrimidine (RNFX). The invention also involves novel and nonintuitive methods for the preparation of RNFX, a specific member of a general class of compounds with the substructure 2,2-bis(difluoramino)-N-nitro-1,3-propanediamine. RNFX is produced by the use of key intermediates, including tetrahydropyrimidin-5(4H)-ones, which allow formation of the target structural subcomponent, 2,2-bis(difluoramino)-N-nitro-1,3-propanediamine, and a more specific substructure of 2,2-bis(difluoramino)-N,N′-dinitro-1,3-propanediamine.
