摘要:The present invention relates to a novel synthesis method for acyl-pantetheine derivatives. The present invention further relates to the use of said synthesized acyl-pantetheine derivatives as a starting material in the enzymatic synthesis of acyl-coenzyme A derivatives. According to a first aspect thereof, the present invention provides a method for the synthesis of acyl-pantetheine derivatives, the method including the steps of: a) providing a source of pantetheine; b) providing a source of acyl ester; and c) contacting the source of pantetheine with the source of acyl ester to form the corresponding acyl-pantetheine derivative, having the general formula (I), wherein R is an acyl group.The present invention also provides a method for the synthesis of acyl-coenzyme A derivatives as well as the use of a source of pantetheine and a source of acyl ester in the preparation steps of these two methods.

摘要:In the synthesis of ascofranone, a compound represented by formula (III), (IV), (V) or (VII) or an optical isomer thereof is used as an intermediate for the synthesis. [In the formulae, R 1 and R 2 independently represent a hydrogen atom, a C 1-7 alkyl group, a phenoxyalkyl group having a halogen atom on a carbon atom in a benzene ring therein, or a phenyl group having a C 1-7 alkoxy group or a C 1-7 alkoxycarbonyl group on a carbon atom in a benzene ring therein; and X represents a halogen atom or a group R 5 SO 3 (wherein R 5 represents a C 1-7 alkyl group or a phenyl group having a C 1-7 alkyl group on a carbon atom in a benzene ring therein).] By using the compound, it becomes possible to reduce the number of steps required for the total synthesis of ascofranone to 7 or 8 from 12 which is a number of the steps required for the conventional ascofranone total synthesis processes.

摘要:The present invention is directed to compositions and methods for enhancing synthesis of nucleic acid molecules, particularly GC-rich nucleic acid molecules. Specifically, the invention provides compositions comprising one or more nitrogen-containing organic compounds having a formula selected from the group consisting of formula I and formula II (or salts or derivatives thereof), preferably 4-methylmorpholine N-oxide or betaine (carboxymethyltrimethylammonium), and further comprising one or more compounds selected from the group consisting of proline and an N-alkylimidazole compound, and more preferably proline, 1-methylimidazole or 4-methylimidazole. The invention further relates to methods for enhanced, high-fidelity synthesis of nucleic acid molecules, including via amplification (particularly PCR), reverse transcription, and sequencing methods. The invention also relates to nucleic acid molecules synthesized by these methods, to fragments or derivatives thereof, and to vectors and host cells comprising such nucleic acid molecules, fragments, or derivatives. The invention also relates to kits for synthesizing, amplifying, reverse transcribing or sequencing nucleic acid molecules comprising one or more of the compositions of the invention.

标题 :Bio-intermediates for use in the chemical synthesis of polyketides
发明人：SANTI DANIEL; ASHLEY GARY; MYLES DAVID C
摘要:The present invention relates to compounds made by a subset of modules from one or more polyketide synthase (“PKSâ€?) genes that are used as starting material in the chemical synthesis of novel molecules, particularly naturally occurring polyketides or derivatives thereof. The biologically derived intermediates (“bio-intermediatesâ€?) generally represent particularly difficult compounds to synthesize using traditional chemical approaches due to one or more stereocenters. In one aspect of the invention, an intermediate in the synthesis of epothilone is provided that feeds into the synthetic protocol of Danishefsky and co-workers. In another aspect of the invention, intermediates in the synthesis of discodermolide are provided that feed into the synthetic protocol of Smith and co-workers. By taking advantage of the inherent stereochemical specificity of biological processes, the syntheses of key intermediates and thus the overall syntheses of compounds like epothilone and discodermolide are greaty simplified.

摘要:The present invention provides an efficient and versatile method for the synthesis and screening of combinatorial libraries of benzimidazoles, benzoxazoles, benzothiazoles, and derivatives thereof. In order to expedite the synthesis of large arrays of compounds possessing these core structures, a general methodology for solid phase synthesis of these derivatives is provided. Arrays of benzimidazoles, benzoxazoles, benzothiazoles, and derivatives thereof useful as peptidomimetics and for the identification of agents having antifungal, antiviral, antimicrobial, anticoagulant, and antiulcer activity, or use in the treatment of inflammation, hypertension, cancer, and other conditions can be prepared by this method.
