摘要:
Described herein are methods of preparing cutin-derived monomers, oligomers, or combinations thereof from cutin-containing plant matter. The methods can include heating the cutin-derived plant matter in a solvent at elevated temperature and pressure. In some preferred embodiments, the methods can be carried out without the use of additional acidic or basic species.
摘要:
The invention relates to a method for decarboxylating C—C bond formation by reacting carboxylic salts with carbon electrophiles in the presence of transition metal compounds as catalysts. The method represents a decarboxylating C—C bond formation of carboxylic acid salts with carbon electrophiles, wherein the catalyst contains two transition metals and/or transition metal compounds, from which one is present, preferably, in the oxidation step, which are different from each other by one unit, and catalyzes a radical decarboxylation which is absorbed during the second oxidation steps, which are different from each other by two units and catalyzes the two electron processes of a C—C bond formation reaction.

摘要:
A cyclohexane derivative having the function of reducing a blood sugar level and having preferable properties required of medicines, such as long-lasting drug activity, metabolic stability, and safety; and a medicinal composition for use in the prevention or treatment of diseases attributable to hyperglycemia, such as diabetes, e.g., insulin dependent diabetes mellitus (type 1 diabetes) or noninsulin-dependent diabetes mellitus (type 2 diabetes), complications of diabetes, and obesity. The derivative is a compound represented by the formula (I): (wherein A is —O—, —CH2—, or —NH—; n is an integer selected between 0 and 1; R6 and R7 each independently is hydrogen or C1-6 alkyl; m is an integer selected among 1-3; Q is selected among the following formulae Q1 to Q5; Ar1 is optionally substituted arylene or optionally substituted heteroarylene, provided that the heteroarylene may be bonded to an aromatic carbocycle or aromatic heterocycle to form a fused ring; and Ar2 is optionally substituted aryl or optionally substituted heteroaryl), a prodrug of the compound, or a pharmaceutically acceptable salt of either. Also provided are a medicine, a medicinal composition, or the like each containing the compound.
摘要:
The invention particularly discloses a process for preparing aryl alkyl carboxylic acid salts by preparing aqueous alkali solution, adding aryl alkyl carboxylic acid to said alkali solution at a temperature ranging from 4° to 121° C. for obtaining a clear solution, preferably by heating and/or stirring and concentrating and cooling to obtain aryl alkyl carboxylic acid salt The invention therefore discloses solid oral dosage forms and compositions of aryl alkyl carboxylic acid salts which are free of organic solvent/so. The solid oral dose compositions of aryl alkyl carboxylic acid salts of the invention are prepared in situ from aryl alkyl carboxylic acids and bases to obtain aryl acid alkyl carboxylic acid sails in crystalline/powder form with or without the use of pharmaceutical excipients.
