BRD7552 是PDX1转录因子诱导剂，它能够上调人类原代胰岛和导管细胞中 PDX1 的表达，诱导 PDX1 启动子的表观遗传变化与转录激活一致，提高胰岛素表达。其中 PDX1 是参与胰腺发育和β细胞功能的关键转录因子。

Protectin D1 (also known as neuroprotectin D1 when produced in neuronal tissues) is a DHA-derived dihydroxy fatty acid that exhibits potent protective and anti-inflammatory activities. 10(S),17(S)-DiHDHA is a DHA metabolite, also referred to as protectin DX (PDX). It is produced by an apparent double lipoxygenase (LO)-mediated reaction in murine peritonitis exudates, in suspensions of human leukocytes, or by soybean 15-LO incubated with DHA. It differs from protectin D1 with respect to the stereochemistry of the C-10 hydroxyl and the double bond configuration at the 13 and 15 positions. 10(S),17(S)-DiHDHA blocks neutrophil infiltration in murine peritonitis by 20-25% at a dose of 1 ng mouse. It also inhibits platelet activation by both impairing thromboxane (TX) synthesis and TX receptor activation.

W1131 是一种有效的STAT3抑制剂，可引发铁死亡。W1131 在胃癌皮下异种移植模型、类器官模型和 PDX 模型中抑制癌症进展。W1131 有效减轻癌细胞对 5-FU 化学耐药性。W1131 调节细胞周期、DNA 损伤反应和氧化磷酸化，包括IL6-JAK-STAT3通路和铁死亡 (ferroptosis) 通路。

Flotetuzumab (MGD006; S80880) 是一种双特异性 CD123 CD3双亲和再靶向 (DART) 抗体。Flotetuzumab 通过同时结合靶细胞的 CD123和效应 T 细胞的CD3，而重新激活 T 细胞，导致 T 细胞介导的靶细胞的细胞毒性。Flotetuzumab 对小鼠中急性髓系白血病 (AML) 患者来源异种移植物 (PDX) 模型具有抑制效力。

YK-029A为口服活性的EGFR突变抑制剂，特异性针对EGFRT790M及EGFRex20ins。该化合物在PDX模型上对肿瘤展现良好的抑制效果，显示出明显的抗肿瘤活性。

W1131 TFA 是一种抑制STAT3并诱导铁死亡(ferroptosis)的有效化合物。在胃癌的皮下异种移植模型、类器官模型以及PDX模型中，它都能显著阻止疾病的发展。此外，W1131能有效缓解癌细胞对5-FU的化学耐药性。该化合物还通过调节IL6-JAK-STAT3和铁死亡(ferroptosis)通路来影响细胞周期、DNA损伤响应和氧化磷酸化过程。
