A peptidyl transferase ribozyme capable of combinatorial peptide synthesis
摘要:
The formation of peptide bonds is a key step in both the chemical and biological synthesis of peptides. The ribozyme can use a wide range of amino acids as its substrate for the dipeptide synthesis. A library containing 29 peptides whose synthesis was catalyzed by this unique ribozyme was analyzed by mass spectrometry. These results implicate that ribozyme may have potential application in the peptide synthesis. (C) 2003 Elsevier Ltd. All rights reserved.

target in AML treatment. Here, we designed and developed an antibody drug conjugate (CD123-CPT) by integrating anti-CD123 antibody with a chemotherapeutic agent, Camptothecin (CPT), via a disulfide linker. The linker is biodegradable in the presence of Glutathione (GSH, an endogenous component in cells), which leads to release of CPT. Anti-CD123 antibody conjugates showed significant higher cellular

The present invention is directed to novel natural product-derived ratjadone-based compounds useful as payloads (or toxins) in drug-conjugates constructs with cell target binding moieties (CTBM) and payload-linker compounds useful in connection with drug conjugates. The present invention further relates to new ratjadone compositions including the aforementioned payloads, payload-linkers and drug conjugates, and methods for using these payloads, payload-linkers and drug conjugates, to treat pathological conditions including cancer, inflammatory and infectious diseases.
