Development of Efficient Covalent Inactivators of a Fungal Aspartate Semialdehyde Dehydrogenase
Aspartate semialdehyde dehydrogenase (ASADH) catalyzes the second step in the fungal pathway towards the synthesis of threonine, isoleucine, and methionine, and it has been identified as a viable target for antifungal drug development. Our previous work produced a group of vinyl sulfones that function as irreversible covalent inactivators of this enzyme. We have now expanded this initial set to produce vinyl sulfones with higher kinetic efficiency as covalent inactivators of ASADH purified from the pathogenic fungal species Candida albicans. The catalytic efficiency of these inactivators has also been compared to related classes of irreversible inactivators, vinyl sulfonamides, acrylamides, and sulfonyl ketones.
期刊介绍：
Drug Development Research focuses on research topics related to the discovery and development of new therapeutic entities. The journal publishes original research articles on medicinal chemistry, pharmacology, biotechnology and biopharmaceuticals, toxicology, and drug delivery, formulation, and pharmacokinetics. The journal welcomes manuscripts on new compounds and technologies in all areas focused on human therapeutics, as well as global management, health care policy, and regulatory issues involving the drug discovery and development process. In addition to full-length articles, Drug Development Research publishes Brief Reports on important and timely new research findings, as well as in-depth review articles. The journal also features periodic special thematic issues devoted to specific compound classes, new technologies, and broad aspects of drug discovery and development.
