Pseudoginsenoside Rh2 has cytotoxicity, it induces mitochondrial apoptosis in A549 cells and is responsible for excessive activation of the Ras/Raf/ERK/p53 pathway. (20Z) -Pseudoginsenoside Rh2 and (20E)-Pseudoginsenoside Rh2 have antioxidative activity.

Tinlorafenib (PF-07284890) (compound 10) 是一种口服具有活力的、具有中枢神经系统 (CNS) 渗透性的 BRAF kinase 抑制剂，能够作用于 BRAFV600E (IC50: 4.25 nM) 和 V600K (IC50: 2.7 nM)。Tinlorafenib 能够用于 BRAF 相关的中枢神经系统恶性和良性肿瘤以及颅外恶性肿瘤的研究。

PF-07284892(ARRY-558)是一种具有口服活性的变构SHP2抑制剂(IC50=21 nM)，能够降低pERK的表达，可用于研究实体瘤。

7alpha,15-Dihydroxydehydroabietic acid may exhibit significant cytotoxic activity.

ADTL-EI1712 is a dual inhibitor of ERK1 and ERK5 (IC50s = 40.43 and 64.5 nM, respectively).1It reduces ERK1 and ERK5 activity by 93.5% and 89.4%, respectively, but also inhibits ERK2 activity by 92.7%, in a panel of 100 kinases at 1 μM. ADTL-EI1712 inhibits proliferation of HL-60 and MKN74, but not HeLa, cancer cells (IC50s = 1.26, 2.55, and >50 μM, respectively). It reduces tumor growth and intratumor phosphorylation of ERK1/2 and ERK5 in an MKN74 mouse xenograft model when administered at a dose of 50 mg/kg per day. 1.Wang, G., Zhao, Y., Liu, Y., et al.Discovery of a novel dual-target inhibitor of ERK1 and ERK5 that induces regulated cell death to overcome compensatory mechanism in specific tumor typesJ.
