3-deazaneplanocin

3-Deazaneplanocin A (DZNep) 是一种组蛋白甲基转移酶 (EZH2) 和 S-腺苷同型半胱氨酸水解酶 (AHCY) 双重抑制剂，具有抗正痘活性，可在动物模型中能够诱导其靶标的蛋白酶体降解并降低毒性，抑制肝脏、肾脏、腹膜和气道的纤维化。

3-deazaneplanocin A HCl 是组蛋白甲基转移酶 (EZH2) 和 S-腺苷同型半胱氨酸水解酶 (AHCY) 抑制剂。

PRIMA-1 (NSC-281668) 是一种突变型 p53复活剂，可恢复 TP53 突变型甲状腺癌细胞对组蛋白甲基化抑制剂 3-Deazaneplanocin A 的敏感性。

S-Adenosylhomocysteine (SAH) hydrolase is responsible for the reversible hydrolysis of SAH into adenosine and homocysteine. Inhibition of this enzyme leads to the accumulation of SAH within cells, thereby increasing the SAH to S-adenosylmethionine (SAM) ratio and subsequently inhibiting SAM-dependent methyltransferases. (−)-Neplanocin A, a potent and irreversible inhibitor of SAH hydrolase (Ki= 8.39 nM), exhibits significant antitumor activity against mouse leukemia L1210 cells and holds broad-spectrum antiviral properties. Its efficacy notably surpasses that of the reversible inhibitor 3-deazaneplanocin, especially in combating vesicular stomatitis, evidencing a higher potency with ID50 values of 0.07 μg/ml for Neplanocin A versus 0.3 μg/ml for 3-deazaneplanocin.
