Design and synthesis of dual inhibitors of HIV reverse transcriptase and integrase: Introducing a diketoacid functionality into delavirdine
摘要:
Cost and toxicity problems associated with highly active antiretroviral therapy (HAART) in HIV/AIDS treatment could be alleviated by using designed multiple ligands (DMLs). Dual inhibitors of HIV reverse transcriptase (RT) and integrase (IN) were rationally designed by introducing a diketoacid (DKA) functionality into the tolerant C-5 site of RT inhibitor delavirdine. The resulting compounds all demonstrate good activity against both RT and IN in enzymatic assays and HIV in cell-based assay, whereas their C-7 regioisomers are all inactive in these assays. Balanced activities were observed with C-3 halogenated inhibitors. (C) 2008 Elsevier Ltd. All rights reserved.

An extensive series of CBI analogues of the duocarmycins and CC-1065 exploring substituent effects within the first indole DNA binding subunit is detailed. In general, substitution at the indole C5 position led to cytotoxic potency enhancements that can be ≧1000-fold providing simplified analogues containing a single DNA binding subunit that are more potent (IC

=2-3 pM) than CBI-TMI, duocarmycin SA, or CC-1065. The increases in cytotoxicity correlate well with accompanying increases in the rate and efficiency of DNA alkylation. This effect is more pronounced with the CBI versus DSA or CPI based analogues. Moreover, this effect is largely insensitive to the electronic character of the C5 substituent but is sensitive to the size, rigid length, and shape (sp, sp
