  • Antiosteoporotic agents
    Patent number: 4125621
    Abstract: It is disclosed that compounds of the formula: ##STR1## WHEREIN Y represents (C.dbd.O).sub.m in which m has a value of 0 or 1; n has a value of 0 or 1; and X represents S, NH or O; provided that there is a COOH substituent at the 1, 2 or 3 position relative to the X group; and further provided that when X is NH and n is 0, the COOH group cannot be at the 2 position; or a nontoxic, pharmaceutically acceptable salt thereof are capable of decreasing the ratio of the rates of bone resorption to bone deposition in a host animal, e.g., in the treatment of osteoporosis.

  • Process of forming a polymeric emulsion which comprises copolymerizing in aqueous dispersion an ethylenically-unsaturated monomer containing quaternary nitrogen
    Patent number: 4064091
    Abstract: A novel class of monomeric emulsion stabilizers consists of certain types of ethylenically unsaturated radicals covalently linked to a quaternary nitrogen atom which in turn is covalently linked to a lipophilic radical. Such monomers will polymerize with other ethylenically unsaturated radicals forming self-stabilized, surfactant-free polymeric dispersions.
    Type: Grant
    Filed: December 19, 1975
    Date of Patent: December 20, 1977
    Assignee: The Kendall Co.
    Inventors: Carlos M. Samour, Mildred C. Richards
  • Process for preparing N-mono(alkoxymethyl) phenobarbitals
    Patent number: 4054565
    Abstract: N-mono (alkoxymethyl)phenobarbitals wherein the alkoxy group has 1 to 4 carbon atoms are disclosed. The compounds are prepared by reacting the dialkali metal salt of thiophenobarbital with chloromethyl alkyl ether followed by treating the resultant N,S-bis(alkoxymethyl)thiophenobarbital with an oxidizing agent. The compounds are useful as anticonvulsant agents.
    Type: Grant
    Filed: September 24, 1975
    Date of Patent: October 18, 1977
    Assignee: Bristol-Myers Company
    Inventors: Julius A. Vida, Carlos M. Samour
  • Monomeric emulsion stabilizers derived from alkyl/alkenyl succinic anhydride
    Patent number: 4051158
    Abstract: Quaternary ammonium salts having a lipophilic group covalently linked to the quaternary nitrogen through hydroxysuccinyloxy or hydroxysuccinylamino radicals are disclosed. These quaternary ammonium salts are useful as monomeric emulsion stabilizers.
    Type: Grant

    Date of Patent: September 27, 1977
    Assignee: The Kendall Company
    Inventors: Carlos M. Samour, Mildred C. Richards
  • Certain barbituric acid derivatives used as anticonvulsant agents
    Patent number: 4046894
    Abstract: Various derivatives of barbituric acid and of diphenylhydantoin are described in which alkoxymethyl or benzyloxymethyl groups are attached to the nitrogen atoms of the rings. Therapeutic compositions containing these compounds and their use as anticonvulsant agents are described.
    Type: Grant

    Date of Patent: September 6, 1977
    Assignee: Bristol-Myers Company
    Inventors: Carlos M. Samour, Julius A. Vida
  • Monomeric morpholinium emulsion stabilizers
    Patent number: 4029658
    Abstract: A novel class of monomeric emulsion stabilizers is prepared by reacting certain quaternary ammonium halides with anionic surfactants. In polymerization reactions these stabilizers become a part of the polymer molecule, which is thereby self-stabilized in aqueous dispersion.
