atf 2

ATF4-IN-2 (Compound 29)，具有47.71 nM的IC50值，是一种有效的ATF4抑制剂，常用于神经退行性疾病的研究。

EIF2α activator 1（Compound 40）为真核生物起始因子2α（eIF2α）磷酸化的激活剂，能够提高EIF2α下游蛋白ATF和CHOP的表达水平。该化合物对K562细胞和PBMC细胞展现出抗增殖活性，其IC50值分别为4.00 μM和19.3 μM。

Melatonin D5, a deuterium-labeled version of melatonin, is a hormone produced by the pineal gland, known for its role as a selective ATF-6 inhibitor that promotes apoptosis in human hepatoma cells via COX-2 downregulation. Additionally, it activates melatonin receptors and exhibits antioxidative and anti-inflammatory properties.
