产品描述 Description

PCI-34051 is a potent and selective HDAC8 inhibitor with an IC₅₀ of 10nM^[1]. Histone deacetylase 8 (HDAC8) is a class I histone deacetylase that modulates chromatin structureplays by removing acetyl groups from histones and influences transcriptional activity^[2]. PCI-34051 is usually used to study the mechanisms of tumor cell apoptosis and the regulation of related signaling pathways^[3].

In vitro, treatment of wild-type p53 ovarian cancer cells with PCI-34051 (20µM; 24-72h) significantly suppresses cell proliferation, enhances cell apoptosis, and inhibits cell migration^[4]. Treatment of human bronchial epithelial cells (HBECs) with PCI-34051 (10µM; 4 days) induced the release of exosomes containing miR-381-3p, inhibited cell proliferation, and triggered cell apoptosis^[5].

In vivo, PCI-34051 (0.5mg/kg; intraperitoneal injection at days 0, 7, and 14) significantly reduced airway hyperresponsiveness, inflammation and airway remodeling in the ovalbumin-sensitized and challenged asthma mice model^[6]. PCI-34051 (20mg/kg; intraperitoneal injection before cisplatin and daily thereafter) significantly reduced renal tubular damage, apoptosis, and DNA damage, and promoted homologous recombination repair in a mice model of cisplatin-induced acute kidney injury (AKI)^[7].

PCI-34051是一种高效且选择性的HDAC8抑制剂，其IC₅₀为10nM^[1]。组蛋白去乙酰化酶 8（HDAC8）是一种Ⅰ类组蛋白去乙酰化酶，通过去除组蛋白上的乙酰基团调节染色质结构，进而影响转录活性^[2]。PCI-34051常用于研究肿瘤细胞凋亡及相关信号通路的调控机制^[3]。

体外实验中，用PCI-34051（3µM；24小时）处理野生型p53卵巢癌细胞可显著抑制细胞增殖，增强细胞凋亡，并抑制细胞迁移^[4]。 PCI-34051（10µM；4天）处理人支气管上皮细胞（HBECs）可诱导释放含有miR-381-3p的外泌体，抑制细胞增殖并触发细胞凋亡^[5]。

体内实验中，在卵清蛋白致敏和刺激的哮喘小鼠模型中，PCI-34051（0.5mg/kg；腹腔注射于第0、7、14天）显著降低了气道高反应性、炎症和气道重塑^[6]。在顺铂诱导的急性肾损伤（AKI）小鼠模型中，PCI-34051（20mg/kg；顺铂治疗前腹腔注射；此后每日注射）显著减轻了肾小管损伤、细胞凋亡和DNA损伤，并促进了同源重组修复^[7]。

实验参考方法 Experimental Reference Method

Cell experiment [1]:
Cell lines	human ovarian cancer cell line, TOV-21G (p53-WT) and A2780 (p53-WT)
Preparation Method	The human ovarian cancer cell line, TOV-21G (p53-WT) and A2780 (p53-WT) were cultured in Roswell Park Memorial Institute medium (RPMI) contained 10% fetal bovine serum, 100U/mL penicillin, and 100µg/mL streptomycin. Cell lines were maintained in 5% CO₂ and 37℃ humidified incubators. Cells were subcultured every 3-4 days. Cells were seeded in 96-well plates containing 130µL medium (3×10³ cells per well). Following overnight incubation, PCI-34051 was treated for 24h, 48h, and 72h. Cell growth and viability were determined by CCK-8 assay. Cell apoptosis was determined Annexin V-FITC Apoptosis Detection Kit. Cells were seeded in the upper chamber of the transwell insert plate (PET membrane, 8µM pore) in a 400µL serum-free medium (1×10⁵ cells per well) and 500µL of medium containing 10% FBS was placed in the lower chamber for Transwell Migration Assay.
Reaction Conditions	20µM; 24-72h
Applications	Treatment of wild-type p53 ovarian cancer cells with PCI-34051 significantly suppresses cell proliferation, enhances cell apoptosis, and inhibits cell migration.
Animal experiment [2]:
Animal models	SPF-grade female BABL/c mice
Preparation Method	SPF-grade female BABL/c mice aged 6-8 weeks and weighing 20±2g were housed in an SPF-grade room for one week and provided water and food ad libitum. Mice were randomly divided into three groups (n=6 for each group): healthy control (con), mice with asthma (ova), and PCI-34051 treatment (pci). Mice of the ova and pci groups were sensitized by intraperitoneal injection of 0.2mL OVA solution (20μg OVA and 2mg aluminum hydroxide in 0.2mL normal saline) at days 0, 7, and 14 to create the asthma model. The OVA challenge was conducted on day 21 using a 2% OVA saline solution with a nebulizer for 30min daily, three times per week for eight weeks, while mice in the control group were administered saline. In the pci groups, PCI-34051 (0.5mg/kg) was administered intraperitoneally before each challenge, and the con and ova groups were administered saline as a control. Airway resistance was estimated using noninvasive wholebody plethysmography. Cytokine levels were measured by Luminex-based immunoassays. Anesthetized mice were sacrificed by cervical dislocation 1 hour after the last OVA challenge. The left lung was fixed with 0.1mL iced 4% polyoxymethylene, removed, and fixed in 4% polyoxymethylene for 24 hours. After rehydration by running tap water for 6 hours, dehydration and embedding in paraffin were performed, and 4μm sections were cut for further analysis. Proteins and RNA were extracted for further analyses.
Dosage form	0.5mg/kg; intraperitoneal injection at days 0, 7, and 14
Applications	PCI-34051 significantly reduced airway hyperresponsiveness, inflammation and airway remodeling in the ovalbumin-sensitized and challenged asthma mice model.
