Title: Inhalator of medicine and method of fluidization of powder medicine for inhalation
Inventor: VILLAX PETER
IPC: A61M16/00
Filed: 1995-02-01
Abstract: A new inhalation device, which during operation causes an aerosol to be formed inside a chamber such as a capsule (4) which occludes one end (3) of the inhalation tube (1), the capsule having holes at its extremities (7,8) which admit airflow. The airflow causes the powder contained inside the capsule to be surprisingly transported to the capsule extremity contrary to the direction of inhalation, that is towards the air entry holes in the capsule, and then to form an aerosol until all powder has been removed from the capsule or chamber through the tube (1), the duration of inhalation being chiefly regulated by the size and proportion of the capsule holes. The tube (1) has air inlets downstream of the capsule to permit a balanced airflow that will transport the finely suspended powder into the lungs, maximizing the fraction of medicament deposited therein. <IMAGE>

Abstract: This invention relates to matrix metalloproteinase (MMP) inhibiting compounds of the formula: <CHEM> where R<1> is C1-C12 alkyl, straight or branched and optionally substituted by halogen, hydroxy, C1-C6 alkoxy, amino, carboxyl, C1-C6 alkoxycarbonyl, carboxamido, nitrile, mono- or di-(C1-C6)alkylamino, thio, C1-C6 alkylthio, aryl, -Oaryl or -OCH2aryl where aryl is optionally substituted with C1-C6 alkyl, C1-C6 alkoxy, carboxy, halogen, cyano, nitro, carboxamido, or hydroxy; and C1-C6 alkanesulfonyloxy. R<2> is  alpha -OH or  beta -OH and R<6> is H or R<2> and R<6> together are carbonyl; the chemical intermediates; and processes for the preparation of these compounds and the intermediates thereto. Matrix metalloproteinases (MMP) are a family of zinc-containing calcium dependent proteinases, including stromelysins, collagenases, and gelatinases. These MMP enzymes are capable of degrading the proteinaceous components of connective tissue and appear to be involved in tissue remodeling, i.e., wound healing and connective tissue turnover. Unexpectedly, the mercaptoalcohols with the S-configuration at the hydroxyl-bearing carbon have been found to be at least 4 times more potent than the analogous (R)-alcohols both in vitro and in vivo in inhibiting the MMP enzyme..
