A method of producing a complex of a lamellar inorganic compound and an organic compound includes: heat-treating a particular non-swelling lamellar inorganic compound within a pyrolysis temperature range of the non-swelling lamellar inorganic compound; and intercalating an organic compound into the non-swelling lamellar inorganic compound in a dispersion liquid in which the heat-treated non-swelling lamellar inorganic compound is dispersed in a medium, thereby inserting the organic compound into an interlamellar space of the non-swelling lamellar inorganic compound.

A novel protocol for the general hydrogenation of nitriles in the absence of basic additives is described. The system is based on the combination of [Ru(cod)(methylallyl)2] (cod=cyclooctadiene) and L2. A variety of aromatic and aliphatic nitriles is hydrogenated under mild conditions (50 °C and 15 bar H2) with this system. Kinetic studies revealed higher activity in the case of aromatic nitriles compared with aliphatic ones.
A 13C and 15N experimental NMR and theoretical study of the structure of linear primary aliphatic amines and ammonium salts: From C1 to C18

experimental part, p. 4633 - 4639 (2011/07/09)
Eighteen aliphatic linear amines, from methylamine to stearylamine, have been experimentally studied by NMR and theoretically calculated at the GIAO/B3LYP/6-311++G(d,p) level. A partial exploration of their conformation has been carried out, mainly to determine the effect on the chemical shifts. In solution and for neutral amines, 15N chemical shifts indicate a mixture of two conformations. In the solid state (CPMAS NMR) only the subset of solid amines has been studied (from C14 to C18). The 15N signals of the corresponding ammonium salts in the solid state depend on the counteranions, Cl- and CF3CO2-, a result that is theoretically proven.
Hydrosiloxane-Ti(OiPr)4: An efficient system for the reduction of primary amides into primary amines as their hydrochloride salts
Laval, Stéphane,Dayoub, Wissam,Pehlivan, Leyla,Métay, Estelle,Favre-Réguillon, Alain,Delbrayelle, Dominique,Mignani, Gérard,Lemaire, Marc
experimental part, p. 4072 - 4075 (2011/09/12)
A simple and useful method for the reduction of primary amides into the corresponding amines using a polymethylhydrosiloxane (PMHS)-Ti(OiPr)4 reducing system is described. Aromatic as well as aliphatic primary amides are reduced in high selectivity and excellent yields. The reduction could proceed via dehydration of the primary amide group into the corresponding nitrile which is then reduced into the corresponding primary amine.
ANTIMICROBIAL POLYMERS AND THEIR USES
-
Page/Page column 23-24, (2009/12/28)
Polymers with non-leaching antimicrobial activity and their use as surface coatings or bulk resins for medical devices. The antimicrobial polymers are prepared with antimicrobial moieties covalently bonded to a polymer chain end or to a polymer backbone at a side chain end. The antimicrobial moiety-containing endgroups include surface active (or surface assembling) moieties which promote enrichment of antimicrobial endgroups at the polymer surface and thus formation of an antimicrobially active surface. Polymers with built-in antimicrobial endgroups can be used as bulk resins, as antimicrobial additives, or as infection preventative coatings in the manufacture of medical devices (e.g., catheters, vascular access devices, peripheral lines, IV sites, drains, gastric feeding and tubes, and other implantable devices). Such materials can also be used as antimicrobial and antifouling coatings on structures in contact with microorganism in environments that require control of biofilm formation, such as marine products.
Lipophilic oligopeptides with immunomodulating activity
-
, (2008/06/13)
New, small and structurally simple immunomodulating oligopeptides are disclosed. The oligopeptides of this invention possess a long, lipophilic alkyl chain. These immunomodulating oligopeptides can be used in conjunction with anti-viral or anti-cancer agents in the treatment of human and animal diseases. Processes for the syntheses of immunomodulating chemicals are also disclosed.
