, R1, R2, and n are defined in the detailed description and claims. The chitosan polymer derivatives of formula I bind to or associate with alpha-4-beta-1 (α4β1) and alpha-V-beta-3 (αVβ3) integrin dimers and can be used in delivery formulations to deliver drugs, nucleic acids, or other therapeutic compounds to tissues or cells expressing such integrins.
This invention provides compounds of Formula I having the structure

Substituted phenylsulfonamides are selective .beta..sub.3 adrenergic receptor agonists with very little .beta..sub.1 and .beta..sub.2 adrenergic receptor activity and as such the compounds are capable of increasing lipolysis and energy expenditure in cells. The compounds thus have potent activity in the treatment of Type II diabetes and obesity. The compounds can also be used to lower triglyceride levels and cholesterol levels or raise high density lipoprotein levels or to decrease gut motility. In addition, the compounds can be used to reduced neurogenic inflammation or as antidepressant agents. The compounds are prepared by coupling an aminoalkylphenyl-sulfonamide with an appropriately substituted alkyl epoxide. Compositions and methods for the use of the compounds in the treatment of diabetes and obesity and for lowering triglyceride levels and cholesterol levels or raising high density lipoprotein levels or for increasing gut motility are also disclosed.
The present invention relates to trisubstituted pyrimidines of formula
