Abstract: Long chain N-alkyl amino and imino compounds, oxa-substituted derivatives thereof, and pharmaceutical compositions including such compounds are described. The long chain N-alkyl group is a C8-C16 alkyl group. The long chain N-alkyl compounds and oxa-substituted derivatives thereof can be used in the treatment of viral infections, in particular hepatitis B virus or hepatitis C virus, in a cell or an individual. For example, the long chain N-alkyl compounds or oxa-substituted derivatives thereof can be derived from piperidines, pyrrolidines, phenylamines, pyridines, pyrroles, or amino acids.

Abstract: The present invention provides a method by which to reversibly render male mammals infertile. Thus, the disclosed N-substituted imino compounds, and pharmaceutical compositions thereof, completely impair the fertility of male mammals, but exhibit no effect on that of female mammals, and are thus useful as male contraceptives.

Abstract: Methods for treating lipid storage diseases using compounds that inhibit glucosyltransferase enzymes are disclosed herein. The invention relates to the treatment of lipid storage disease with compounds that inhibit glucosyltransferase activity in the affected cells. It relates particularly to the use of 1,5-dideoxy-1,5-imino-D-glucitol and derivatives thereof.

Abstract: A novel method is disclosed for the treatment of a patient affected with Gaucher's disease or other such glycolipid storage diseases. The method comprises administering to said patient a therapeutically effective amount of a long-chain N-alkyl derivative of deoxynojirimycin to alleviate or inhibit the glycolipid storage disease. The long-chain alkyl group has from nine to about 20 carbon atoms and preferably is nonyl or decyl.

Abstract: Novel N-alkyl derivatives of deoxygalactonojirimycin are provided in which said alkyl contains from 3-6 carbon atoms. These novel compounds are useful for selectively inhibiting glycolipid synthesis.

Abstract: A method is disclosed for modifying the carbohydrate moiety on glycoproteins to facilitate the structural and functional analysis of said glycoproteins such as by NMR spectroscopic analysis and crystallography which comprises treating glycoprotein-secreting mammalian cells having low endomannosidase activity under cell culture maintenance conditions with a glucosidase I inhibitor, and after secretion and purification, subsequent treatment of the active glycoprotein with endoglycosidase H to thereby provide a glycoprotein with a single GlcNAc residue at each glycosylation sequon. The preferred mammalian cells are CHO cells and the preferred glucosidase I inhibitor is N-butyl deoxynojirimycin.

Abstract: A method is disclosed for the treatment of Tay-Sachs disease comprising subjecting said cells to a glycolipid inhibitory effective amount of an N-alkyl derivative of 1,5-dideoxy-1,5-imino-D-glucitol in which said alkyl contains from 2-8 carbon atoms.

Abstract: A method is disclosed for the in vivo treatment of patients having a lysosomal storage disease with a significant central nervous system (CNS) involvement. Said method comprises administration to said patient a small but storage-inhibitory effective amount of an N-alkyl derivative of a 1,5-iminosugar in which said alkyl group contains from about 2 to about 8 carbon atoms and said 1,5-iminosugar is 1,5-dideoxy-1,5-imino-D-glucitol, or 1,5-dideoxy-1,5-imino-D-galactitol, or an O-acylated pro-drug of said 1,5-iminosugar. In an illustrative example, CNS storage of GM2 ganglioside is inhibited in Tay-Sachs mice by administration of 1,5-(butylimino)-1,5-dideoxy-D-glucitol.
