摘要:
The present invention relates to novel cyclic peptides that may be conjugated with imaging agents, including novel imaging agents. Specifically, it includes c(KRGDf; SEQ ID NO. 3) NIR imaging compositions and novel cyclic HWGFTL (SEQ ID NO. 5) polypeptides which may be used inter alia in NIR, MRI and nuclear imaging as well as therapy. Additionally, the invention includes novel imaging agents, such as TS-ICG derivatives. The invention also relates to methods of making and using such compounds. Such uses include both pre-operative and intraoperative detection of tumor cells and treatment monitoring.

摘要:
The present invention provides nonradioactive NIR optical imaging agents based up on the structure of retinoid acid derivatives. The nonradioactive NIR optical imaging agent has been evaluated at the cellular level by confocal microscopy, and in vivo in a whole animal using a various xenograft models. The specific uptake of this agent in human cancer cells and multiple xenograft models demonstrate that nonradioactive near infrared dye labeled retinoid metabolites and/or analogs are useful for early stage cancer studies and diagnoses. Also, the present invention provides that nonradioactive near infrared dye labeled retinoid metabolites and/or analogs are useful for visualization of drug redistribution within the body which is useful in determining the optimal biological dose. Ultimately, the visualization data can be used as an analytical tool to reduce any systemic toxicity.
摘要:
Multi-modal tumor imaging of neuroblastoma is essential for tumor staging, response evaluation and detection of relapsed diseased. The present invention provides a norepinephine analogue with a near-infrared (near-IR) dye, W765-BG, that efficiently and stably detects neuroblastoma in vivo using near-IR optical imaging. Confocal microscopy and optical imaging of neuroblastoma xenografts shows cell specific uptake and reveals exceptional tumor retention with a high tumor-to-tissue ratio up to 7 days after injection of W765-BG.
