摘要:
Disclosed are thioglycoside analogs of gangliosides represented by the formula ##STR1## in which Y represents a radical of the following formula ##STR2## and X represents a radical of the formula ##STR3## wherein m is an integer of 15 to 25, l is an integer of 0 to 3 and n is an integer of 11 to 15. The thioglycoside analogs are expected to exert specific enzyme-inhibitory effects.

摘要:
The present invention provides novel ruthenium compounds of Formula (I): or salts, isomers, hydrates, or solvates thereof, or combinations thereof; wherein E, R1, R2, R3, R4, R5, X1, and X2 are as defined herein, and pharmaceutical compositions thereof. Also provided are methods of use and treatment. Such compounds have been found useful in the treatment of malaria infection. Such compounds may also be useful in the treatment of inflammatory conditions, such as acute lung injury and acute resipiratory distress syndrome, which optionally may be associated with a malaria infection.

摘要:
A combinatorial chemical library of compounds structurally related to the moenomycin class of antibiotics has the formula ##STR1## wherein D is a donor mono- or disaccharide, A is an acceptor monosaccharide, and P-R is a lipophosphoglycerate mimetic group. Members of the library have a glycosidic linkage between the anomeric carbon of D and the C2 carbon of A, and the D-A moiety is in turn covalently linked through the anomeric carbon of A to the P-R group. Members of the library exhibit their greatest structural diversity in terms of substitutions occurring at the C3 position of the A residue, substitutions at the C2 position of the D residue, and different P-R groups used in assembling the compounds. Members of the library are preferably synthesized by solid phase techniques involving stepwise coupling of the respective units to a support, functionalizing the A and/or D saccharides either before or after immobilizing them on the support, and cleaving the assembled compounds from the support. Preferred functionalities attached to the sugar residues are amides, carbamates, ureas, sulfonamides, substituted amines, esters, carbonates, and sulfates. Exemplary P-R groups are derivatives of homoserine, glyceric acid, salicylates and mandelic acid. Members of the library can be screened for anti-microbial activity by contacting them with a culture of microbes and monitoring the growth rate of the microbes.

The present invention relates to compounds and compositions useful as antioxidants and in particular to selenium containing compounds of formula (I): wherein n is 1, 2, or 3; m is 2, 3, 4, or 5; and each R] is independently —(optionally substituted C1-C3 alkylene) p-OH, where p is 0 or 1, or a salt thereof. The invention also relates to the use of these seleno-compounds in the treatment of diseases or conditions associated with increased levels of oxidants produced by myeloperoxidase (MPO), such as for instance, atherosclerosis.
