"There are few reported methods for combining two or three different imaging dyes, metals, or dye-metal combinations, followed by the conjugation of a disease- targeting group to enable the use a given imaging system for multiple imaging applications. Previously, peptides have been used as scaffolds for dyes and metals used in diagnostic techniques such as optical molecular imaging (OMI), positron emission tomography (PET), and magnetic resonance imaging (MRI). The aim of this project was to reassemble peptide-based imaging agents through a modular method by coupling together modules comprised of amino acids with imaging agents attached to their side chains to form “imaging peptides,” followed by attaching a cancer-targeting group in the final step. This new modular approach for the synthesis of a diverse set of targeted molecular imaging agents (TMIAs) was optimized and exemplified by the synthesis of dual modal PET-MRI, dual OMI-MRI and dual metal (di-gadolinium for MRI), and the partial synthesis of a tri-modal OMI-PET-MRI agent. The dual modal imaging peptides were conjugated through a linker to targeting groups for lung cancer (A549 cells) and prostate cancer (PSMA positive C4-2) cells. In addition to imaging applications for early detection, active surveillance, image guided biopsies and surgery, this modular approach could potentially be used for creating therapeutic agents to treat cancer patients."--Abstract.

Molecular imaging is a rapidly emerging field that translates many concepts developed for molecular biology and cellular imaging to the in vivo imaging of intact organisms. The technique allows the study of molecular biological events in their full context and will therefore become an indispensable tool for biomedical research and drug discovery and development.This volume familiarizes the reader with the concepts of imaging and molecular imaging in particular. Basic principles of imaging technologies, reporter moieties for the various imaging modalities and the design of target reporter constructs are described in the first part. The second part illustrates how these tools can be used to visualize relevant molecular events: the biodistribution of drugs/ligands, the expression of drug targets (receptors, enzymes), and the consequences of the molecular drug-target interactions (pathway activations, system responses). A final chapter deals with visualization of cell migration (cell therapies).

Over the past decades, the field of molecular imaging has been rapidly growing involving multiple disciplines such as medicine, biology, chemistry, pharmacology and biomedical engineering. Any molecular imaging procedure requires an imaging probe that is an agent used to visualize, characterize and quantify biological processes in living systems. Such a probe typically consists of an agent that usually produces signal for imaging purpose, a targeting moiety, and a linker connecting the targeting moiety and the signaling agent. Many challenging problems of molecular imaging can be addressed by exploiting the great possibilities offered by modern synthetic organic and coordination chemistry and the powerful procedures provided by conjugation chemistry. Thus, chemistry plays a decisive role in the development of this cutting-edge methodology. Currently, the diagnostic imaging modalities include Magnetic Resonance Imaging (MRI), Computed Tomography (CT), Ultrasound (US), Nuclear Imaging (PET, SPECT), Optical Imaging (OI) and Photoacoustic Imaging (PAI). Each of these imaging modalities has its own advantages and disadvantages, and therefore, a multimodal approach combining two techniques is often adopted to generate complementary anatomical and functional information of the disease. The basis for designing imaging probes for a given application is dictated by the chosen imaging modality, which in turn is dependent upon the concentration and localization profile (vascular, extracellular matrix, cell membrane, intracellular, near or at the cell nucleus) of the target molecule. The development of high-affinity ligands and their conjugation to the targeting vector is also one of the key steps for pursuing efficient molecular imaging probes. Other excellent reviews, text and monographs describe the principles of biomedical imaging, focusing on molecular biology or on the physics behind the techniques. This Research Topic aims to show how chemistry can offer molecular imaging the opportunity to express all its potential.
