TCS PrP Inhibitor 13 (5-(4-Nitrophenyl)-2-Phenyl-4H-Pyrazol-3-One) 是一种抗朊病毒剂，可抑制蛋白酶抗性朊病毒蛋白的积累。它诱导神经鞘瘤细胞调亡，在ScN2a 和F3细胞株中均显示IC50值为3 nM。

1-(4-Methoxyphenyl)-3-methyl-1H-pyrazol-5(4H)-one (Compound 2) 在 ScN2a 及 F3 细胞系中表现出显著的抗朊病毒效果，其半抑制浓度(IC50)分别达到 13 nM 与 25 nM。

ARN1468 (compound 5) is a highly effective orally active inhibitor of serpins. Inhibition of serpins activity by ARN1468 enables release of proteases, thereby reducing prion accumulation. ARN1468 demonstrates pronounced anti-prion effects in ScGT1 RML, ScGT1 22L, ScN2a RML, and ScN2a 22L cell lines, with EC 50 values of 8.64, 19.3, 11.2, and 6.27 μM [1].
