drug design (see above, Figure 3) remains quite promising to creative science. Indeed, targetedreceptor<br />

screening of synthetic chemical libraries of highly modified peptide molecules (e.g., Nsubstituted<br />

Gly “peptoids” [21] is rapidly expanding our database of structurally diverse ligands. Such<br />

structurally unique lead compounds will provide the opportunity for further pharmacophore modeling<br />

strategies to be used in the discovery of novel agonists or antagonists at GPCR and other receptor types.<br />
