Abstract:
The subject invention pertains to a modified MCIR peptide ligand comprising a peptide that is a melanocortin 1 receptor (MCIR) ligand and a functionality or linker, such as a click functionality, for conjugation to a surface or agent. The modified MCIR peptide ligand can be coupled, e.g. , via a click reaction with a complementary click functionality attached, to a moiety to form an MClR-targeted agent. Drugs, contrast agents, polymers, particles, micelles, surfaces of larger structures, or other moieties can be targeted to the MCIR. The subject invention also pertains to a MCIR peptide ligand-micelle complex comprising a peptide that is a melanocortin 1 receptor ligand connected via a click reaction product to a micelle. The micelle is stable in vivo and can target melanoma tumor cells by association of the peptide ligand with the MCIR or the tumor and selectively provide a detectable and/or therapeutic agent (such as an imageable contrast agent and/or anti-cancer agent) selectively to the tumor cell.
Abstract:
A sorting apparatus and method for directed sort combinatorial chemical synthesis is provided. This invention relates to a directed flexible, sorting apparatus and method for combinatorial chemical synthesis using a directed split and recombine process. The process utilizes one algorithm that is universal in directing and sorting a library of any size. This invention further provides a method of sorting solid supports for combinatorial chemical synthesis comprising delivering one or more supports which are organized in a one dimensional linear array in one or more reaction vessels, to an isolation and transfer chamber, transferring one or more support from each of said reaction vessels to one or more subsequent reaction vessels, in a patterned distribution; wherein the patterned distribution of supports in each subsequent transfer is identical and the position of each support in a reaction vessel codes for its previous synthesis history. In another aspect, the invention provides a directed sort apparatus wherein all members of a set at a given point in time are reacted with the same chemical building blocks throughout synthesis.
Abstract:
Cellular targets on cancer cells have been identified that can be used with targeted molecular imaging to detect the cancer cells in vivo. Non-invasive methods for detecting cancer cells, such as metastasized cancer cells, are therefore provided. Also provided are compositions and kits for use in the disclosed methods.
