Halogen Attached Directly To The Diazine Ring By Nonionic Bonding Patents (Class 544/334)
  • Patent number: 7045660
    Abstract: This invention is directed to a [di(ether or thioether)heteroaryl or fluoro substituted aryl] compound or an N-oxide thereof or a pharmaceutically acceptable salt thereof, which is useful for inhibiting the production or physiological effects of TNF in the treatment of a patient suffering from a disease state associated with a physiologically detrimental excess of tumor necrosis factor (TNF). Compounds within the scope of the present invention also inhibit cyclic AMP phosphodiesterase, and are useful in treating a disease state associated with pathological conditions that are modulated by inhibiting cyclic AMP phosphodiesterase, such disease states including inflammatory and autoimmune diseases, in particular type IV cyclic AMP phosphodiesterase. The present invention is therefore directed to their pharmacological use for inhibiting TNF and/or cyclic AMP phosphodiesterase, pharmacological compositions comprising the compounds and methods for their preparation.

  • Patent number: RE39056
    Abstract: Compounds of structural Formula (I) and pharmacologically acceptable salts and esters thereof possess 5?-reductase inhibitory activity. These compounds inhibit 5?-reductase type 1 and type 2. The compounds of structural Formula I are useful in the systemic, including oral, and parenteral, including topical, treatment and prevention of hyperandrogenic conditions including prostatic carcinoma, benign prostatic hyperplasia, acne vulgaris, seborrhea, androgenic alopecia (also called androgenetic alopecia) which includes male- and female-pattern baldness, female hirsutism, and prostatitis. A class of compounds of the present invention are also potent antiandrogens. The present invention also relates to novel compositions containing such compounds, methods of their use and methods of their manufacture.
