Structure-guided optimization of small molecules inhibiting human immunodeficiency virus 1 Tat association with the human coactivator p300/CREB binding protein-associated factor.

چکیده
Human immunodeficiency virus 1 (HIV-1) trans-activator Tat recruits the human transcriptional coactivator PCAF (p300/CREB binding protein-associated factor) to facilitate transcription of the integrated HIV-1 provirus. We report here structure-based lead optimization of small-molecule inhibitors that block selectively Tat and PCAF association in cells. Our lead optimization was guided by grand-canonical ensemble simulation of the receptor/lead complex that leads to definition of chemical modifications with improved lead affinity through displacing weakly bound water molecules at the ligand-receptor interface.

Interaction of human immunodeficiency virus type 1 Tat with the transcriptional coactivators p300 and CREB binding protein.
Human immunodeficiency virus type 1 (HIV-1) encodes the transactivator protein Tat, which is essential for viral replication and progression to disease. Here we demonstrate that transcriptional activation by HIV-1 Tat involves p300 or the related cellular transcriptional coactivator CREB binding protein (CBP). Tat transactivation was inhibited by the 12S form of the adenovirus E1A gene product,...
متن کاملHIV-1 Tat interactions with p300 and PCAF transcriptional coactivators inhibit histone acetylation and neurotrophin signaling through CREB.
The human immunodeficiency virus type-1 (HIV-1) infects microglia, macrophages, and astrocytes in the central nervous system (CNS) and may cause severe neurological diseases, such as AIDS-related dementias or progressive encephalopathies, as a result of CNS inflammation and neurotrophin signaling defects associated with expression of viral antigens and HIV-1 replication in the brain. The HIV Ta...
متن کاملEnhancement of Nuclear Factor- B Acetylation by Coactivator p300 and HIV-1 Tat Proteins*
Nuclear factor (NF)B transcription factors are involved in the control of a large number of normal cellular and organismal processes, such as immune and inflammatory responses, developmental processes, cellular growth, and apoptosis. Transcription of the human immunodeficiency virus type 1 (HIV-1) genome depends on the intracellular environment where the integrate viral DNA is regulated by a co...
متن کاملHIV-1 tat transactivator recruits p300 and CREB-binding protein histone acetyltransferases to the viral promoter.
In cells infected with HIV type 1 (HIV-1), the integrated viral promoter is present in a chromatin-bound conformation and is transcriptionally silent in the absence of stimulation. The HIV-1 Tat protein binds to a stem-loop structure at the 5' end of viral mRNA and relieves this inhibition by inducing a remodeling of the nucleosome arrangement downstream of the transcription-initiation site. He...
متن کاملStructural basis of lysine-acetylated HIV-1 Tat recognition by PCAF bromodomain.
The human immunodeficiency virus type 1 (HIV-1) trans-activator protein Tat stimulates transcription of the integrated HIV-1 genome and promotes viral replication in infected cells. Tat transactivation activity is dependent on lysine acetylation and its association with nuclear histone acetyltransferases p300/CBP (CREB binding protein) and p300/CBP-associated factor (PCAF). Here, we show that t...
