Journal ArticleDOI

Optimization, biological evaluation and microPET imaging of copper-64-labeled bombesin agonists, [64Cu-NO2A-(X)-BBN(7–14)NH2], in a prostate tumor xenografted mouse model

TL;DR: No2A chelator sufficiently stabilizes copper(II) radiometal under in vivo conditions, producing conjugates with very high uptake and retention in targeted GRPr in tumor-bearing mice and preclinical evaluation in patients provides some impetus for clinical evaluation in human patients.
Journal ArticleDOI

Evidence for the Influence of Diet on Cranial Form and Robusticity

TL;DR: Analysis of three‐dimensional coordinate landmark data indicate that the basicrania of hard/tough diet rabbits exhibit more robust middle cranial fossae and pterygoid plates, as well as altered overall morphology of the caudal Cranial fossa, suggesting that long‐term variation in masticatory forces associated with differences in dietary properties can contribute to the complex and multifactorial development of neurocranial morphology.
Journal ArticleDOI

Pyrazolyl conjugates of bombesin: a new tridentate ligand framework for the stabilization of fac-[M(CO)3]+ moiety

TL;DR: The tridentate pyrazolyl ligand framework is suggested to be an ideal candidate for the design and development of low-valent (99m)Tc-based diagnostic radiopharmaceuticals based on BBN or other targeting vectors.
Journal ArticleDOI

Evaluation of the pharmacokinetic effects of various linking group using the 111In-DOTA-X-BBN(7-14)NH2 structural paradigm in a prostate cancer model.

TL;DR: Evaluating the pharmacokinetic profile of aliphatic hydrocarbon, aromatic, and poly(ethylene glycol) (ether) functional groups indicated that radioconjugates incorporating aromatic linking groups generally demonstrated enhanced retention in BB2r expressing tissues in comparison to either the hydrocarbon or ether linking moieties.
Journal ArticleDOI

In vitro and in vivo analysis of [64Cu-NO2A-8-Aoc-BBN(7–14)NH2]: a site-directed radiopharmaceutical for positron-emission tomography imaging of T-47D human breast cancer tumors

TL;DR: The pharmacokinetic profile justifies investigation of this bioconjugate as a potentially useful diagnostic/therapeutic agent and would serve as a good starting point for modification and optimization of similar agents to maximize tumor uptake and minimize nontarget accumulation.
