标 题 :Synthesis of pharmaceutical compositions with lactams and β-lactams/oxo thia azabicyclo compounds
发明人：THIRUMALACHAR MANDAYAM JEERSAN; NARASIMHAN JR MANDAYAM JEERSAN
摘要:Pharmaceutical compositions with heretofore unknown and enhanced physical, chemical, and biological properties are prepared by combining known biologically active parent compounds with oxo thia azabicyclo compounds, such as lactam and beta -lactam compounds, capable of rapidly transporting the parent compounds in undegraded form to their target sites of action. A process for combining the parent compound with beta -lactam compounds consists of dissolving the parent compound in a polar solvent, adding a beta -lactam compound, incubating the resulting mixture, followed by drying, and subjecting the remaining solid material to solvent washing or extraction to further purify the new pharmaceutical composition. The new pharmaceutical composition possesses the biological and therapeutic activity of the parent compound and the barrier penetrating characteristics of the beta -lactam compound, which results in improved pharmacodynamics, including bioavailability, and an improved chemotherapeutic index, such that lower amounts of the parent may be used to avoid the toxic effects of the parent compound. Some of the new pharmaceutical compounds provide for the first time parent compounds in an orally administerable form.

标 题:Low temperature synthesis of vitreous bodies and their intermediates
发明人：SAMANTA M
权利人:SAMANTA M
摘要:A method of making glass of high purity and in virtually unlimited shapes via solution deposition on a porous self-supporting body by reaction between a first solution and a second solution; an a product made thereby. The rust solution containing at least one basic glass forming solute is confined within a porous container, the walls of which are substantially impermeable to the basic solute. The second solution containing at least one acidic solute is diffused into the porous container through its walls which are substantially permeable to the said acidic solute. The reaction between the rust solution and the second solution takes place within the porous container leading to the deposition of a self-supporting porous body on the inside walls of the container. The porous body which is crystalline, vitreous or intermediate between the two, is purified by leaching and/or washing, dried and thermally consolidated, to a transparent non-porous glass.

标 题 :Formation of lactams and other amides under mild conditions by action of cyanogen
发明人：DAY RICHARD A
权利人:UNIV CINCINNATI
摘要:A method for the formation of intramolecular amide bonds by the action of cyanogen, under mild reaction conditions, in the preparation of cyclic amides, including lactams, in biologically active compounds. A compound containing at least one carboxylic acid group and at least one primary or secondary amino group is reacted with cyanogen to form an intramolecular amide bond. The method has utility in the synthesis of B-lactam antibiotics, such as penicillins, cephalosporins, and their derivatives, in enzyme modification, in cyclization of peptides, and in covalent cross-linking of proteins.
