摘要:
A pharmaceutical composition includes, as an active ingredient, a compound according to formula 1436 as shown in FIG. 1, or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable carrier or excipient. Various pharmaceutical products may be produced including this pharmaceutical composition. Such pharmaceutical products may be used for the treatment of obesity or diabetes. Methods for using the pharmaceutical compositions also are described. In these methods, various diseases are treated or other body functions are activated or inhibited by administering an effective amount of the pharmaceutical composition. For example, diabetes and obesity may be treated by administering an effective amount of the pharmaceutical compositions. Weight gain and growth factor production can be inhibited by administering an effective amount of these pharmaceutical compositions. Appetite can be suppressed by administering an effective amount of the pharmaceutical compositions, and a diuretic effect can be produced.

摘要:
Aminosterol compounds are described that are useful as inhibitors of the sodium/proton exchanger (NHE). Methods of using such aminosterols compounds are also enclosed, including those employing compounds that are inhibitors of a spectrum of NHEs as well as those using compounds that are inhibitors of only one specific NHE. Advantageous screening techniques and assays for evaluating a compound's therapeutic activity are also disclosed.
