Transition metal-catalyzed oxidativecleavage of carbon-carbon multiple bonds has emerged as a powerful tool in organic synthesis. High-valent oxometals, mostly of Ru, Os, Mn, Mo, W, and Re, were used catalytically as reactive oxygen transfer agents to the multiple bonds. Reported here for the first time are the organocatalytic versions of the oxidativecleavage reactions. Our method involves use of

The present invention provides immunogenic oligosaccharide compositions and methods of making and using them. In particular, the compositions comprise native O-linked and S-linked oligosaccharides coupled to a protein carrier via a linker, wherein the resultant conjugate elicits a protectively immunogenic response, particularly in vaccines against pathogenic
Candida
species and more particularly against
Candida albicans
. Preferably the pathogenic
Candida
species are those that possess cell wall oligosaccharide compositions similar to the β-mannan component of
Candida albicans
cell walls.
Novel maytansinoids of the formula:
wherein X is H or Cl, and R is a hydrocarbon residue or an azaheterocyclic group, said R group having at least one of water-soluble substituents, have antimitotic, antitumor and antimicrobial activities.
式中的新型美坦素类化合物
其中 X 是 H 或 Cl,R 是烃残基或杂环基团,所述 R 基团至少有一个水溶性取代基,具有抗杀菌、抗肿瘤和抗微生物活性。
