Disclosed herein, the invention pertains to methods and compositions that find use in radiosensitization of tumors and tumor samples based on the ability of a tumor sample to cleave a MTS molecule of the present invention. The MTS molecules of the present invention have a formula as disclosed herein and wherein A is a peptide with a sequence comprising 5 to 9 consecutive acidic amino acids, wherein the amino acids are selected from: aspartates and glutamates; B is a peptide with a sequence comprising 5 to 20 consecutive basic amino acids; X and Y are linkers; P is an optional pre-targeting moiety; M is an optional macromolecular carrier; and T is a radiosensitization agent for delivery to a target, including for example a therapeutic compound.

Tumor radiosensitization with monomethyl auristatin E (MMAE) and derivatives thereof

Disclosed herein, the invention pertains to methods and compositions that find use in treatment, diagnosis, prognosis and characterization of disease and disease samples based on the ability of a disease sample to cleave a MTS molecule of the present invention. The MTS molecules of the present invention have a formula as disclosed herein and wherein A is a peptide with a sequence comprising 5 to 9 consecutive acidic amino acids, wherein the amino acids are selected from: aspartates and glutamates; B is a peptide with a sequence comprising 5 to 20 consecutive basic amino acids; X and Y are linkers; P is a pre-targeting moiety; M is a macromolecular carrier, C is a detectable moiety; and T is a compound for delivery to a target, including for example a therapeutic compound.

Pretargeted activatable cell penetrating peptide with intracellularly releasable prodrug

The invention provides compositions useful as molecular probes. In particular, the invention provides activatable cell penetrating peptides comprising a fluorescence donor and a fluorescence acceptor. Exemplary fluorescence donors and fluorescence acceptors include compounds derived from cyanine. Also provided are ratiometric, multispectral, and excitation lifetime imaging methods for detecting the molecular probes provided herein.
