摘要:
This document describes biochemical pathways for producing 7-hydroxyheptanoic acid using a polypeptide having monooxygenase activity to form a 8-hydroxynonanoate intermediate, which can be converted to 7-hydroxyheptanoate using a polypeptide having monooxygenase activity, a polypeptide having secondary alcohol dehydrogenase activity, and a polypeptide having esterase activity. 7-hydroxyheptanoic acid can be enzymatically converted to pimelic acid, 7-aminoheptanoic acid, heptamethylenediamine or 1,7 heptanediol. This document also describes recombinant hosts producing 7-hydroxyheptanoic acid as well as pimelic acid, 7-aminoheptanoic acid, heptamethylenediamine and 1,7 heptanediol.
摘要:
The invention provides a method for obtaining the intermediate (II), useful for manufacturing Valsartan and a drug directed to a treatment of arterial hypertension or heart failure. The process comprises a) Imination of the aldehyde group of a compound (VII) by L-Valine (IV) salts with organic or inorganic bases and a polar solvent or water, where X means halogen or an —OSO2R group, where R is CF3, tolyl, methyl or F; to give an imine-type compound (VIII), where B+ is the protonated form of an organic base or an alkaline cation; b) Reduction of the imine group of the compound (VIII) followed by acidification, to give the compound (VI); and c) N-Acylation of the compound (VI) with valeryl chloride to give the compound (II). Steps a) and b) can be performed in a “one pot” reaction.

This invention relates to polymerizable ultraviolet light absorbers and yellow colorants and their use in ophthalmic lenses. In particular, this invention relates to polymerizable ultraviolet light absorbing methine compounds and yellow compounds of the methine and anthraquinone classes that block ultraviolet light and/or violet-blue light transmission through ophthalmic lenses.
摘要:
Disclosed is a process for producing a benzylamine derivative represented by the general formula (3): wherein X1, R1 and R2 are as defined below, which comprises reacting a benzyl derivative represented by the general formula (1): wherein X1 represents a halogen atom and R1 represents an acyl group, with a haloacyl compound represented by the general formula (2): R2—X2 (2) wherein X2 represents a halogen atom and R2 represents an acyl group, in the presence of Lewis acid. According to this method, a benzylamine derivative as an intermediate, which is useful for the preparation of a carbamate-based agricultural or horticultural bactericide, can be preferably prepared.
摘要:
The present invention provides a drug delivery vehicle that can improve the pharmacokinetics of pharmacological agents. The invention relates to a multifunctional carrier capable of delivering a carried material such as a pharmacological agent or genetic material to a recipient. The multifunctional carrier includes a multifunctional core and a plurality of adduct molecules bonded thereto. The molecular carrier has surface functional groups which can be associated with a carried material. The carried material can be associated with the molecular carrier through covalent interactions or ionic interactions. The polyvalent core can be ethylene-diamine tetraacetic acid (EDTA) or succinic acid. The invention also relates to methods for producing and using such molecules.
