Peptidyl hydroxamic acids as methionine aminopeptidase inhibitors
摘要:
A new class of methionine aminopeptidase (MetAP) inhibitors, which contain an internal hydroxamate (N-acyl-N-alkylhydroxylamine) core as the metal-chelating group, has been designed, synthesized, and tested. The compounds exhibited reversible, competitive inhibition against Escherichia coli MetAP as well as human MetAP-l and MetAP-2. The most potent inhibitor had a K-i value of 2.5 muM and > 20-fold selectivity toward E. coli MAP. (C) 2003 Elsevier Ltd. All rights reserved.

a molecular logic system, by which a combinatorial recognition of the input signals is utilized to efficiently processchemically encoded information. Each chemical input can target simultaneously multiple domains on the same molecular platform, resulting in a unique combination of chemical states, each with its characteristic fluorescence output. Simple alteration of the input reagents changes the

protected at the molecular scale. By harnessing the principles of molecular Boolean logic, we have designed a moleculardevice that mimics the operation of an electronic keypad lock, e.g., a common security circuit used for numerous applications, in which access to an object or data is to be restricted to a limited number of persons. What distinguishes this lock from a simple molecular logic gate is the

The present invention relates to novel disulfur bridge linkers containing hydrazine used for the specific conjugation of compounds/cytotoxic agents to a cell-binding molecule, through bridge linking a pair of thiols on the cell-binding molecule. The invention also relates to methods of making such linkers, and of using such linkers in making homogeneous conjugates, as well as of application of the conjugates in treatment of cancers, infections and autoimmune disorders.
