MedKoo Cat#: 555391 | Name: PF3450074
Featured New

Description:

WARNING: This product is for research use only, not for human or veterinary use.

PF-3450074, also known as PF74, is a HIV-1 inhibitor that targets HIV capsid protein. PF74 binds specifically to HIV-1 particles and triggers premature HIV-1 uncoating in target cells. PF74 Inhibits HIV-1 Integration by Altering the Composition of the Preintegration Complex. PF74 Reinforces the HIV-1 Capsid To Impair Reverse Transcription-Induced Uncoating.

More Info
Biological target:
PF-3450074 (PF-74) is a specifical inhibitor of HIV-1 capsid protein (CA) and displays a broad-spectrum inhibition of HIV isolates with submicromolar potency (EC50=8-640 nM).
In vitro activity:
It was assessed whether PF74 could additionally antagonize NUP153C engagement by CA in the context of HIV-1 infection, given the caveat that one could not unambiguously correlate data from protein binding assays with effects from PF74-induced capsid destabilization in cells. PF74 exhibited dose-dependent inhibition of WT HIV-1 and N74D CA mutant viral infection, but had no effect on CA mutant T54A/N57A, which lacks the critical Asn57 side-chain necessary for PF74 binding. WT virus was noticeably less sensitive to PF74 in Trim-NUP153C expressing cells, with an EC90 of 5.65 µM as opposed to 0.65 µM in control cells. The competing effect of PF74 on Trim-NUP153C inhibition seemingly occurred between the concentrations of 0.1 and 1 µM, as the inhibition curves within the two cell lines were nearly superimposable outside of these concentrations. N74D CA mutant virus also exhibited a shift in the PF74 EC90 concentration in Trim-NUP153C cells, though this occurred at higher PF74 concentrations than with the WT virus. Reference: PLoS Pathog. 2013;9(10):e1003693. https://pubmed.ncbi.nlm.nih.gov/24130490/
In vivo activity:
The altered dependence of 4Mut and 5Mut infection on expression of TNPO3 and RanBP2 prompted examination of the fitness of 4Mut in primary targets of HIV-1 replication in vivo—i.e., CD4+ T cells and macrophages. Activated primary CD4+ T cells supported robust replication of wild-type X4- and R5-tropic HIV-1 (Fig. 9A). In contrast, and as observed with the CEM T cell line, 4Mut was markedly attenuated, as was 5Mut. Addition of PF74 or BI-2 promoted 4Mut replication in the cells. In macrophages, in contrast, replication of the 4Mut virus (rendered CCR5 dependent by replacement of the NL4-3 env by that of HIV-1.BaL) was severely impaired and was not stimulated by PF74 or BI-2. Surprisingly, replication of the N74D mutant, which we had included as a control, was markedly stimulated by PF74 and BI-2 in macrophages at drug concentrations that were only moderately inhibitory toward the wild-type virus. We conclude that the 4Mut virus, while exhibiting features of the N74D mutant in terms of host factor requirement, responds differently to capsid-targeting inhibitors in macrophages.
