  Method and compositions for targeted drug delivery to the lower GI tract

  摘要：

  一种用于将物质定向传递到下消化道的组合物和方法包括一个基础或支架载体，药物或前药被固定或共价连接在其中。当口服该化合物时，它会穿过患者的消化道到达下消化道，在那里细菌的偶氮还原酶酶会裂解键，释放药物或前药从基础或支架载体中释放，从而使药物传递到消化道中的目标细胞类型的附近。基础或支架作为副产品留在粪便中排出消化道。

  Abstract Dichloromethane is shown to be a useful solvent in catalytic hydrogenation reactions of easily reduced functional groups (alkenes, alkynes, imines, and nitroarenes) using palladium on carbon as the catalyst under mild conditions (ambient pressure and temperature).

• Design, Synthesis, and Testing of a Molecular Truck for Colonic Delivery of 5-Aminosalicylic Acid

  A molecular scaffold bearing eight terminal alkyne groups was synthesized from sucrose. Eight copies of an azide-terminated, azo-linked precursor to 5-aminosalicylic acid were attached to the scaffold via copper(I)-catalyzed azide alkyne cycloaddition. The resulting compound was evaluated in a DSS model of colitis in BALB/c mice against sulfasalazine as a control. Two independent studies verified that the novel pro-drug, administered in a dose calculated to result in an equimolar 5-ASA yield, outperformed sulfasalazine in terms of protection from mucosal inflammation and T cell activation. A separate study established that 5-ASA appeared in feces produced 24-48 h following administration of the pro-drug. Thus, a new, orally administered pro-drug form of 5-aminosalicylic acid has been developed and successfully demonstrated.

  The present invention provides a composition comprising a disaccharide where at least one of the hydroxyl groups of the disaccharide is attached to a linker. The terminal portion of the linker also includes a drug that is attached via a functional group that is capable of releasing the drug in vivo. Compositions of the invention are useful for delivering the drug at or near inter alia lower GI tract. In some embodiments, compositions of the invention are used for, but not limited to, treating diseases of the colon, and in particular, inflammatory bowel disease, microscopic colitis, and eosinophilic colitis.
