摘要:
A process for the preparation of a fuel oil (diesel fuel or heating oil) composition which is a mixture of an alkanol tranesterified fatty acid ester triglyceride and an acetal of glycerol is described. The process preferably provides a prestep of the formation of at least some of the alkanol transesterif ied triglyceride containing the glycerol for use in the formation of the acetal of glycerol . The composition can also be formed from a reaction of 1,1- dimethoxy- or 1, l-diethoxye thane and glycerol to form the acetal in the alkanol transesterif ied triglyceride.
摘要:
An euthanasia solution based upon gamma-hydroxybutramide and a cardiotoxic amount of a compound selected from chloroquine and quinacrine is described. The composition provides effective euthanasia without unwanted side effects.
摘要:
A process for producing organic acid esters using continuous countercurrent reactive distillation using acid catalysts in a structured packing in a single column (10) is described. In the reactive distillation an organic acid ester is formed by chemical reaction and can be purified to its final state within the single column. Organic acid esters are produced at relatively low cost, with less waste production, and in a less complicated manner than prior processes. Organic acid ester havé uses as solvents, as intermediate chemicals, and in consumer products.
摘要:
A process for producing 2-thiaquiolizidines which are glycosidase and glycosyltransferase inhibitors is described. The compounds are of the formula:
摘要:
The present invention provides compositions and methods for the prevention and treatment of primary and metastatic neoplastic diseases and infectious diseases, for stimulating an immune response in a subject, and for use as an alternative to interleukin-12 (IL-12) treatment. In particular, the present invention provides Apicomplexa-related proteins (ARPs) that have immune stimulatory activity and thus have uses in the treatment and prevention of cancer and infectious diseases and in immune modulation. Compositions comprising an ARP are provided. Methods of use of an ARP for the prevention and/or treatment of cancer and/or infectious diseases, for use as an alternative to interleukin-12 (IL-12) treatment, and for eliciting an immune response in a subject, are also provided.
摘要:
The present invention relates to compositions and methods for the production of Betaine lipids. The methods of the present invention comprise the expression of recombinant enzymes (e.g. from Rhodobacter sphaeroides) in host cells (e.g. bacteria, yeast, and plants) to produce Betaine lipid compounds including, but not limited to, Diacylglyceryl-O-4'-(N,N,N,-trimethyl) homoserine (DGTS). The methods and compositions of the present invention may be utilized such that the amount of phosphate containing fertilizer required for the growth of a particular plant is decreased.
摘要:
Chitin has been discovered to accumulate in the diseased tissue of mammals, including humans, afflicted with a disease characterized by formation of congo red-staining plaques. Such diseases include Alzheimer's disease, spongiform encepalopathies, type II diabetes, atrial amyloidosis, and the like. A method for detecting the chitin in the mammal is described which is useful for diagnosing disease caused by accumulation of the chitin or amyloid plaques comprising chitin in tissue. Further described is a method for treating a disease in the mammal caused by the accumulation of chitin or amyloid plaques comprising chitin by administering a composition which inhibits formation of the chitin or degrades the chitin.

摘要:
A process for preparing N-(substituted)-C- (substituted methyl)-oxazolidinones, C-(substituted methyl)-oxazolidinones, and N-(substituted)-C- (substituted ethyl)-oxazolidinones, preferably chiral, from optically active C-(protected oxymethyl) oxazolidinones is described. The process can be used to produce combinatorial libraries of the above substituted oxazolidinones in a two or three step reaction comprising a plurality of reagents differing in numbers of carbons or particular substituted oxazolidinones. A number of substituted oxazolidinones produced using the above process have been discovered to have antimicrobial activity.
