Ribosomal S6 Kinase (RSK) Inhibitor

RMC-7977 is an orally active triple-complex RAS inhibitor that can simultaneously bind to cyclophilin A (CYPA) (K_d = 195 nM) and KRAS (G12V) (K_d = 292 μM). It exhibits broad-spectrum inhibitory activity against KRAS, NRAS, and HRAS proteins and their various wild-type and mutant variants. RMC-7977 induces apoptosis by inhibiting the phosphorylation of ERK, CRAF, and RSK, as well as increasing PARP cleavage. This leads to tumor regression, reduces resistance in KRAS^G12C cancer models, and demonstrates good tolerability across various RAS cancer models.

Sapanisertib (INK-128; MLN0128; TAK-228) is an orally active dual mTORC1/mTORC2 inhibitor.

Sapanisertib is applicable to research on melanoma, ovarian cancer, pulmonary fibrosis, and hematological malignancies.

Carnosol is a potent Ribosomal S6 Kinase (RSK2) inhibitor that could be useful for treating gastric cancer, with an IC₅₀ of ~5.5 μM. Carnosol, a Nrf2 activator, increases the nuclear levels of Nrf2 and can promote the expression of heme oxygenase 1 (HMOX1).

Brassinin is an indole derivative found in cruciferous plants. Brassinin acts as an IDO inhibitor (K_i = 97.7 μM). Brassinin inhibits angiogenesis and induces apoptosis, autophagy, paraptosis, ROS production, and ER stress. Brassinin selectively stimulates lysosomal degradation of Tie2 and promotes lysosomal and proteasomal degradation of FGFR1 in endothelial cells, downregulating AKT and ERK phosphorylation. Brassinin inhibits endothelial cell proliferation, migration, tube formation, spheroid sprouting, and angiogenesis. Brassinin inhibits PI3K/Akt/mTOR/S6K1 signaling, upregulates p21 and p27, and induces G1 phase cell cycle arrest through RB hypophosphorylation. Brassinin inhibits tyrosinase catalytic activity, reduces tyrosinase mRNA, and inhibits MITF nuclear translocation. Brassinin is used for research on triple-negative breast cancer, chronic myeloid leukemia, colon cancer, glioma, atherosclerosis, and skin cancer.
