Patent number: 6455573Abstract: A method for synthesizing Salacinol, its stereoisomers, and non-naturally occurring selenium and nitrogen analogues thereof having the general formula (I): The compounds are potentially useful as glycosidase inhibitors. The synthetic schemes comprise reacting a cyclic sulfate with a 5-membered ring sugar containing a heteroatom (X). The heteroatom preferably comprises sulfur, selenium, or nitrogen. The cyclic sulfate and ring sugar reagents may be readily prepared from carbohydrate precursors, such as D-glucose, L-glucose, D-xylose and L-xylose. The target compounds are prepared by opening of the cyclic sulfates by nucleophilic attack of the heteroatoms on the 5-membered ring sugars. The resulting heterocyclic compounds have a stable, inner salt structure comprising a heteroatom cation and a sulfate anion. The synthetic schemes yield various stereoisomers of the target compounds in moderate to good yields with limited side-reactions.Type: GrantFiled: July 28, 2000Date of Patent: September 24, 2002Assignee: Simon Fraser UniversityInventors: B.

Patent number: 5648486Abstract: 2,5-Diaryl tetrahydrofurans, 2,5-diaryl tetrahydrothiophenes, 2,4-diaryl tetrahydrofurans, 2,4-diaryl tetrahydrothiophenes, 1,3-diaryl cyclopentanes, 2,4-diaryl pyrrolidines, and 2,5-diaryl pyrrolidines are disclosed that reduce the chemotaxis and respiratory burst leading to the formation of damaging oxygen radicals of polymorphonuclear leukocytes during an inflammatory or immune response. The compounds exhibit this biological activity by acting as PAF receptor antagonists, by inhibiting the enzyme 5-lipoxygenase, or by exhibiting dual activity, i.e., by acting as both a PAF receptor antagonist and inhibitor of 5-lipoxygenase.A method to treat disorders mediated by PAF or leukotrienes is also disclosed, that includes administering an effective amount of one or more of the above-identified compounds or a pharmaceutically acceptable salt thereof, optionally in a pharmaceutically acceptable carrier.Type: GrantFiled: May 12, 1993Date of Patent: July 15, 1997Assignee: CytoMed, Inc.Inventors: Xiong Cai, Sajjat Hussoin, San-Bao Hwang, David Killian, T.

Patent number: 5484872Abstract: The present invention provides a cyclic sulfide compound represented by a general formula (I) ##STR1## (where R.sup.1 represents --CH.sub.2 --CH.sub.2 --, --CH.sub.2 --CH.sub.2 --CH.sub.2 --, --CH.sub.2 --O--CH.sub.2 --, --CH.sub.2 --O--, or --CH.sub.2 --S--). According to this invention, a novel cyclic sulfide compound which gives high refractive index and high Abbe number can be obtained. The polymerizable compositions for manufacturing optical products with this compound as their main component can be readily molded into plastic lenses which give superhigh refractive indices and high Abbe numbers or those which give high refractive indices and high Abbe number with low sp.grs. in addition thereto. The castings obtained from said polymerizable compositions are useful as plastic lenses for glasses, manifesting optical uniformity and being excellent in processability, transparency, and thermal, impact and light resistance.Type: GrantFiled: March 14, 1995Date of Patent: January 16, 1996Assignee: Daiso Co., Ltd.Inventors: Hiroyuki Kanesaki, Tetsuyuki Saika, Masafumi Mikami
