Synthesis and Biological Properties of Amino Acid Amide Ligand-Based Pyridinioalkanoyl Thioesters as Anti-HIV Agents
摘要:
Hyper-mutable retroviruses such as HIV can become rapidly resistant to drugs used to treat infection, Strategies for coping with drug-resistant strains of virus include combination therapies. using viral protease and reverse transcriptase inhibitors. Another approach is the development of antiviral agents that attack mutationally nonpermissive targets that have functions essential for viral replication. Thus, the highly conserved nucleocapsid protein. NCp7, was chosen as a prime target in our search for novel anti-HIV agents that can overcome the problem of viral drug resistance. Recently, we reported (J. Med. Chem. 1999 42, 67) a novel chemotype, the pyridinioalkanoyl thioesters (PATEs), based on 2-mercaptobenzamides as the thiol component and having its amide nitrogen substituted with various phenylsulfonyl moieties. These compounds were identified as relatively nontoxic anti-HIV agents in the XTT cytoprotection assay. In this study. we wish to report a separate genre of active PATEs wherein the thiol component consists of an N-2-mercaptobenzoyl-amino acid derivative. Active derivatives (EC50 < 10 muM) reported herein were confined to amino acid primary amides or methyl amides having side chains no larger than isobutyl. Amino acids terminating in free carboxyl or carboxylic acid ester groups were mostly inactive. Selected compounds were shown to be active on chronically infected CEM/SK-1, TNFalpha-induced U1. ACH-2 cells and virucidal on cell-free virus, latently infected U I cells and acutely infected primary peripheral blood mononuclear cells (PBMCs). (C) 2002 Elsevier Science Ltd. All rights reserved.

The HIV-1 nucleocapsid protein NCp7, which contains two highly conserved zinc fingers, is being used as a novel target for AIDS therapy due to its pivotal role in viral replication and its mutationally intolerant nature. Herein we report a new class of NCp7 inhibitors that possess good antiviral activity with low cellular toxicity.

Certain thiol and acylthiol compounds inhibit retrovirus growth by attacking the highly conserved zinc finger regions of essential viral proteins. These compounds, compositions containing them, and methods of using them to treat retroviral infections such as HIV are described. These compounds are also useful for preparation of vaccines comprised of inactivated retroviruses such as HIV, prevention of the transmission of such retroviruses, and detection of retroviral proteins.
