Paragraph 0046; 0047; 0061; 0062, (2016/10/24)
A method for preparing polyamine by direct ammoniation of a polyhydroxy compound is disclosed. By using a polyhydroxy compound, ammonia gas or liquefied ammonia as a raw material and using a carrier-loaded liquid-phase reduced transition metal as a catalyst, an ammoniation reaction of the polyhydroxy compound under mild conditions is realized. The catalyst has high selectivity of polyamine. The catalyst can be recovered and recycled.

, (2008/06/13)
Methods are disclosed for preparing linear or/and partial precross-linked poly-g-glutamic acid nanoparticle products, their reaction with compounds which contain vinyl groups, and the polymerization by chemical initiation or photopolymerization of these by light of predetermined wavelength. The final products of the present invention are useful as local drug delivery systems, dental surgery, and for inhibition of post-surgical adhesion. The hydrogels made from the biopolymers of the present invention may also be used in controlled release devices, superabsorbent materials and biomaterials like enzyme immobilization.
A General Route to the Synthesis of N-Protected 1-Substituted and 1,2-Disubstituted Taurines

N-Benzyloxycarbonyl protected α-substituted and αβ- disubstituted taurines were synthesized from olefins and epoxides via N-benzyloxycarbonylamino alcohol thioacetates as key intermediates. They are important sulfur analogues of naturally occurring amino acids and building blocks for the synthesis of α-substituted and α,β- disubstituted β-sulfonopeptides.

Novel carbamic esters possessing a carbohydrate moiety derived from glycerol or D-glucose with two N,N-diethyldithiocarbamoyl groups and a series of bisdithiocarbamic esters having a ketone or an alkyl ester have been synthesized. The in vitro activity of these new compounds was evaluated against Fusarium oxysporum f. sp. lini. Some of the compounds [bis[1,3-S-(N,N-diethyldithiocarbamoyl)]-1,3-dideoxyglycerol) and diethyl N,N'-(1,3-dideoxyglycer-1,3-diyl)bis(dithiocarbamate)] were more active for inhibiting vegetative mycelium growth than, respectively, the commercial N,N-diethyldithiocarbamic acid sodium salt and Maneb. The structure activity of these new compounds is discussed.
