PF-3450074 (Synonyms:PF-74)
目录号 : KM6994 CAS No. : 1352879-65-2 纯度 : 98%

PF-3450074 (PF-74) 是 HIV-1 衣壳蛋白 (HIV-1 CA) 的特异性抑制剂,对 HIV 分离株表现出广谱抑制作用,显示出亚微摩尔级别的效价 (EC50=8-640 nM)。PF-3450074 (PF-74) 在 HIV-1 感染的早期阶段起作用,通过与 CPSF6 和 NUP153 的结合直接竞争来抑制病毒复制,并阻断病毒生命周期的脱膜,组装和逆转录步骤。CPSF6:核宿主因子裂解和聚腺苷酸特异性因子 6;NUP153:核孔蛋白 153。

生物活性

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). PF-3450074 (PF-74) acts at an early stage of HIV-1 infection, inhibits viral replication by directly competing with the binding of CPSF6 and NUP153, and blocks the uncoating, assembly, and the reverse transcription steps of the viral life cycle. CPSF6: nuclear host factors cleavage and polyadenylation specific factor 6; NUP153: nucleoporin 153.

体外研究

PF-3450074 (PF-74) exhibits anti-viral activities against HIV wild type NL4-3 and HIV T107N mutant with EC50 values of 0.72 μM and 4.5μM, respectively.
PF-3450074 (PF-74) displays a good potency in primary human peripheral blood mononuclear cells (PBMCs), inhibits HIV-193RW025, HIV-1JR-CSF and HIV-193MW965 with IC50 values of 1.5 ± 0.9 μM; 0.6 ± 0.20 μM; and 0.6 ± 0.10 μM, respectively. This compound shows Median IC50 and CC50 values of 0.9 ± 0.5 μM and 90.5 ± 5.9 μM, respectively.
The KD for the interaction between PF-74 and the CA hexamer, derived in the same manner as for NUP153, is determined to be 176 ± 78 nM.
PF-3450074 (PF-74) (10 μM; 8 hours) results in a marked reduction in late products of reverse transcription in HeLa-P4 cells with DNase I-treated stocks of Env-defective HIV-1 (R9.Env).

    请依序添加每种溶剂: 10% DMSO    90% corn oil

    Solubility: ≥ 6.25 mg/mL (14.69 mM); Clear solution

    此方案可获得 ≥ 6.25 mg/mL (14.69 mM,饱和度未知) 的澄清溶液,此方案不适用于实验周期在半个月以上的实验。

    以 1 mL 工作液为例,取 100 μL 62.5 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中,混合均匀。
