Abstract: Disclosed is a phenyl boronic acid compound represented by Structural Formula (I): Ar is a substituted or unsubstituted aryl group. Z and Z? are independently —O—, —NH— or —S—. X is an electron withdrawing group. R is a substituted or unsubstituted straight chained hydrocarbyl group optionally comprising one or more amine, ammonium, ether, thioether or phenylene linking groups and Y is —H, an amine, —[NH—(CH2)q]r—NH2, halogen, —CF3, thiol, ammonium, alcohol, —COOH, —SO3H, —OSO3H or phosphonium group covalently bonded to the terminal position of R. Each —NH— in —[NH—(CH2)q]r—NH2 is optionally N-alkylated or N,N-dialkylated and —NH2 in —[NH—CH2)q]r—NH2 is optionally N-alkylated, N,N-dialkylated or N,N,N-trialkylated. q is an integer from 2 to about 10 and r is an integer from 1 to about 5.

Abstract: The invention relates to a method for removing bile salts from a patient in need thereof and compositions useful in the method. The method comprises administering to the patient a therapeutically effective amount of a salt of an alkylated and crosslinked polymer. The alkylated and crosslinked polymer salt comprises the reaction product of crosslinked polymers, or salts and copolymers thereof having amine containing repeat units, with at least one aliphatic alkylating agent.

Abstract: A method for removing bile salts from a patient that includes administering to the patient a therapeutically effective amount of a non-absorbable amine polymers characterized by a repeat unit having the formula: and salts thereof, where n is a positive integer and x is zero or an integer between 1 and about 4.

Abstract: Phosphate-binding polymers are provided for removing phosphate from the gastrointestinal tract. The polymers are orally administered, and are useful for the treatment of hyperphosphatemia.

Abstract: Disclosed are polymers comprising one or more phenyl boronate ester, boronamide or boronate thioester groups. The phenyl boronate ester, boronamide and boronate thioester groups are represented by one of the following structural formulas: Ar in Structural Formulas (I) and (II) is substituted or unsubstituted; and each Z is —O—, —NH— or —S— and is independently selected. Pharmaceutically acceptable salts of the polymer are also included. The aryl boronate ester, boronamide or boronate thioester can be cleaved to release the corresponding aryl boronic acid. Also disclosed are pharmaceutical compositions comprising the polymers of the present invention and a pharmaceutically acceptable carrier or diluent; and methods of treating a subject for obesity with the polymers of the present invention.
