177Lu-AMBA: Synthesis and characterization of a selective 177Lu-labeled GRP-R agonist for systemic radiotherapy of prostate cancer.
UNLABELLED Gastrin-releasing peptide receptors (GRP-R) are upregulated in many cancers, including prostate, breast, and lung. We describe a new radiolabeled bombesin (BBN) analog for imaging and… Expand

Preclinical evaluation of an 131I-labeled benzamide for targeted radiotherapy of metastatic melanoma.
Radiolabeled benzamides are attractive candidates for targeted radiotherapy of metastatic melanoma as they bind melanin and exhibit high tumor uptake and retention. One such benzamide,… Expand

In vitro and in vivo metabolism of Lu-AMBA, a GRP-receptor binding compound, and the synthesis and characterization of its metabolites.
The metabolism of (177)Lu-AMBA (AMBA = DO3A-CH(2)CO-G-(4-aminobenzoyl)-QWAVGHLM-NH(2)), a radiotherapeutic compound in clinical development that binds to GRP and NMB receptors, was studied in vitro… Expand

Radioiodination of Rhenium Cyclized α-Melanocyte-Stimulating Hormone Resulting in Enhanced Radioactivity Localization and Retention in Melanoma
Radiohalogenated α-melanocyte-stimulating hormone (α-MSH) analogs were proposed for melanoma imaging and potential radiotherapy because α-MSH receptors are overexpressed on both mouse and human… Expand

Modification of the structure of a metallopeptide: synthesis and biological evaluation of (111)In-labeled DOTA-conjugated rhenium-cyclized alpha-MSH analogues.
Rhenium-cyclized CCMSH analogues are novel melanoma-targeting metallopeptides with high tumor uptake, long tumor retention, and low background in normal tissues, which make these metallopeptides an… Expand

Melanoma-targeting properties of (99m)technetium-labeled cyclic alpha-melanocyte-stimulating hormone peptide analogues.
Preliminary reports have demonstrated that (99m)technetium (Tc)-labeled cyclic [Cys(3,4,10), D-Phe7]alpha-MSH(3-13) (CCMSH) exhibits high tumor uptake and retention values in a murine melanoma mouse… Expand
