摘要:
Activity-based probes, which are specific for certain active cysteine proteases (caspase, cathepsin and legumain) and carry radioactive labels, are disclosed. The present probes comprise an acyloxymethyketone (AOMK) “warhead” that binds only to active enzyme. The probes further comprise peptide-like structure that targets the probe to a specific cysteine protease or protease family, and a radiolabel on the probe, which is bound to the targeted enzyme. It has been found that the present probes are stable in vivo and give specific target images distinguishable over background. The preferred probes are labeled with a positron-emitting agent such as 64Cu, 125I (SPECT) and 99mTc (PET). The probes show in vivo half-life and stability well suited for imaging.

摘要:
An composition in a method for noninvasively monitoring the expression of therapeutic transgene delivered ex vivo and in vivo for the treatment of diseases includes the step of quantitatively imaging a reporter gene expression which is coupled to a therapeutic gene on a plasmid vector to infer levels, location, or duration of the therapeutic gene expression in the targeted tissues or organs. The reporter gene is imaged using a radiopharmaceutical for scintigraphic imaging of the gene expression interactions with the reporter gene, namely positron emission tomography, gamma camera or single-photon emission computed tomography. The genes are delivered with a liposome encapsulated reporter-therapeutic linked transgene vector with balanced reporter/therapeutic transgene expression. A transgene composition includes the reporter gene linked to the therapeutic gene or genes incorporated in and delivered by a liposome encapsulated reporter-therapeutic linked transgene vector.
