N-(3-nitro-4-alkoxybenzoyl)amino acid compounds as well as preparation method and application thereof

The invention discloses N-(3-nitro-4-alkoxybenzoyl)amino acid compounds as well as a preparation method and an application thereof and belongs to the field of medicines. 4-hydroxy-3-nitrobenzoic acidis subjected to methanol esterification, bromo-alkane substitution, hydrolysis and chlorination and then acylated with L-phenylglycine, R2 which is L-phenylglycine sodium salt is obtained, and the N-(3-nitro-4-alkoxybenzoyl)amino acid compounds are obtained after hydrolysis. The N-(3-nitro-4-alkoxybenzoyl)amino acid compounds have novel chemical structures, have good effects in an in-vitro xanthine oxidase inhibition activity test and can be used for treating and preventing gout diseases.

Amphiphilic α-helix mimetics based on a benzoylurea scaffold

The design and synthesis of amphiphilic benzoylurea α-helix mimetics is described. These conformationally constrained molecules allow for the correct angular and spatial projection of hydrophobic and hydrophilic groups and thus the reproduction of side-chains on both faces of an α-helix.

PROCESS FOR PRODUCING 3-NITRO-4-ALKOXYBENZOIC ACID

The present invention provides a process for preparing 3-nitro-4-alkoxybenzoic acid, which comprises the step of subjecting a mixture comprising 4-alkoxybenzoic acid and 40-80% nitric acid, wherein the amount of the 40-80% nitric acid is equal to or more than 8 times that of 4-alkoxybenzoic acid by weight, to a reaction at a temperature of 30-100°C.

AMINE COMPOUNDS

The present invention provide a compound of the formula:wherein ring A represents an aromatic ring optionally having substituents; B, Y and Ya are the same or different and each represents a bond, etc.; R1 and R2 are the same or different and each represents a hydrogen atom, etc.; R3 represents a hydrogen atom, etc.; R4 and R5 are the same or different and each represents a hydrogen, etc.; R6 represents an indolyl group optionally having substituents; and Z and Za are the same or different and each represents a hydrogen atom, etc.; or a salt thereof or a prodrug thereof, having a somatostatin receptor binding inhibition activity and is useful for preventing and/or treating diseases associated with somatostatin.
