got1

GOT1 inhibitor-1 (GOT1 inhibitor 2c) 是一种新型的、非共价的谷氨酸草酰乙酸转氨酶 1 (GOT1) 抑制剂(IC50:8.2 uM)，是一种戊酸衍生物。 它可用于以及胰腺导管腺癌 (PDAC) 。

iGOT1-01 是一种天冬氨酸转氨酶 1 (谷氨酸草酰乙酸转氨酶 1；GOT1) 抑制剂，在 GOT1/GLOX/HRP 测定中IC50为 11.3 μM，在 MDH 偶联 GOT1 酶法测定中IC50为 85 μM。它显示出抗癌活性。

Adapalene (CD271) 是一种合成类视黄醇，局部应用于痤疮。它以非竞争性方式抑制 GOT1的酶活性，具有抗肿瘤活性。它是一种 RAR 激动剂，对 RARβ、RARγ、RARα的AC50值分别为 2.3 nM、9.3 nM 和 22 nM。

Aspulvinone O is a fungal metabolite that has been found in P. variotti and has antioxidant and anticancer activities.1,2 It scavenges 2,2-diphenyl-1-picrylhydrazyl radicals in a cell-free assay (IC50 = 11.6 μM).1 Aspulvinone O inhibits aspartate transaminase 1 (GOT1; Kd = 3.32 μM) and is cytotoxic to PANC-1, AsPC-1, and SW1990 pancreatic cancer cells (IC50s = 20.54-26.8 μM).2 It reduces the oxygen consumption rate (OCR) and induces apoptosis in SW1990 cells. Aspulvinone O (2.5 and 5 mg kg) reduces tumor growth in an SW1990 mouse xenograft model. |1. Zhang, P., Li, X.-M., Wang, J.-N., et al.

MC3138 (10 μM, 24 h) 在PDAC细胞中抑制GOT1蛋白的赖氨酸乙酰化，降低其酶活性。

Aspulvinone H is a natural inhibitor of glutamic oxaloacetate transaminase 1 (GOT1), suppressing glutamine metabolism, making PDAC cells sensitive to oxidative stress and inhibiting cell proliferation, exhibiting potent in vivo antitumor activity in an SW1990-cell-induced xenograft model.
