JNJ-64619178 是一种选择性的、口服活性的、假不可逆的蛋白质精氨酸甲基转移酶 5 抑制剂，IC50为 0.14 nM，有用于肺癌的研究潜力。

JNJ-64619178 is a selective, orally active, and pseudo-irreversible inhibitor of protein arginine methyltransferase 5 (IC50: 0.14 nM). It has effective activity In lung cancer.

JNJ-64619178 displays effective and broad inhibition of cellular growth. JNJ-64619178 binds simultaneously to the S-adenosylmethionine (SAM)- and protein substrate- binding pockets of the PRMT5/MEP50 complex with a pseudo-irreversible mode-of-action [1].

In several non-small cell lung cancer and small cell lung cancer mouse xenograft models, JNJ-64619178 (p.o.) causes efficient inhibition of dimethylation of SMD1/3 proteins, components of the splicing machinery and direct substrates of the methylosome [1].
