bacterial ribosome and inhibits peptide bond formation. As an approach for modifying and potentially improving properties of this inhibitor, we explored ribosome binding and inhibitory activity of a number of aminoacidanalogs of CHL. The L-histidyl analog binds to the ribosome with the affinity exceeding that of CHL by 10 fold. Several of the newly synthesized analogs were able to inhibit protein synthesis
This invention relates to a novel class of compounds which are cysteine protease inhibitors, including but not limited to, inhibitors of Cathepsins K and L. These compounds are useful for treating diseases in which inhibition of bone resorption is indicated, such as osteoporosis.
Amino Acids and Peptides; 60.<sup>1</sup>Synthesis of Biologically Active Cyclopeptides; 10. Synthesis of 16 Structural Isomers of Dolastatin 3; II:<sup>2</sup>Synthesis of the Linear Educts and the Cyclopeptides
Sixteen isomers of the cancerostatic cyclopeptide Dolastatin 3 of marine origin are synthesized. The proposed structure of Dolastatin 3 is proved to be not correct.

Background Kahalalide F (KF) and its isomer iso-kahalalide F (isoKF), both of which can be isolated from the molluskElysiarufescens and itsdiet alga Bryopsis pennata, are potent cytotoxic agents that have advanced through five clinical trials. Due to a short half-life, narrow spectrum of activity, and a modest response in patients, further efforts to modify the molecule are required to address its limitations
