Abstract: This invention relates to a new synthetic process for the preparation of anti-tumor agent Etoposide (VP16-213). the process, which has shorten reaction route, simple procedure, high yield and low materials cost, therefore facilitates the commercial manufacture of etoposide.

Abstract: The invention provides an antidote to blood anticoagulants comprising Factor VIII or fragments of Factor VIII which retain its activity or a substance which increases its concentration in blood.

Abstract: Circulating heparin in a mammal may be neutralized without substantial depletion of platelets or leukocytes by administering to the mammal a heparin neutralizing amount of purified PF4 or rPF4 or a heparin neutralizing fragment thereof.

Abstract: The present invention relates to novel sweet compounds derived from the leaves of the subtropical weed Abrus precatorius, and their use as sweeteners. In particular, the present invention contemplates four novel sweet compounds isolated from A. precatorius or A. fruticulosus, and particularly, Abrusosides A, B, C and D and related compounds. The present invention also contemplates the use of these abrusosides and related compounds as sugar substitutes. The present invention contemplates the use of Abrusosides A-D as individual components or in mixtures, in a method for sweetening comestibles, foodstuffs, beverages and medicinal agents.

Abstract: A purified oligosaccharide consisting of a hexasaccharide with a native molecular weight of 959 which can be isolated from the cell walls of Streptococcus oralis. The oligosaccharide is able to significantly block the interaction between the human oral plaque bacteria Streptococcus oralis H1 and Capnocytophaga ochracea ATCC 33596. This purified oligosaccharide contains saccharide components found to inhibit many know interactions between plaque bacteria and may be effective in prevention, inhibition and reversal of dental plaque deposits. The oligosaccharide may be applied effectively when incorporated in toothpastes, mouth wash, etc.
