Oncrasin-1 is an RNA polymerase inhibitor. Oncrasin-1 suppresses the phosphorylation of the largest subunit of RNA polymerase II and the expression of intronless reporter genes in sensitive cells. Oncrasin-1 effectively kills various human lung cancer cells with K-Ras mutations. Oncrasin-1 leads to coaggregation of PKCι and splicing factors into megaspliceosomes. Oncrasin-1 induces malfunction in the RNA processing machinery. Oncrasin-1 is an anti-cancer agent and can therefore be studied in research for lung cancer.

ARS-1323 is a KRAS G12C inhibitor. ARS-1323 specifically binds to the cysteine residue on the mutant K-Ras protein, locks it in the GDP-bound conformation, thereby blocking K-Ras activation and downstream signaling pathways. ARS-1323 can be used to investigate the signal transduction mechanisms and growth characteristics of tumor cells driven by K-Ras G12C.

PHT-7.3 is a selective inhibitor of connector enhancer of kinase suppressor of Ras 1 (Cnk1) pleckstrin homology (PH) domain (K_d=4.7 μM). PHT-7.3 inhibits mut-KRas, but not wild-type KRas cancer cell and tumor growth and signaling. PHT-7.3 has antitumor activity.

ADT-1004 is an orally active prodrug of ADT-007 (HY-157887). ADT-007 is a reversible, highly potent and selective pan-RAS inhibitor that binds to the nucleotide-free conformation of RAS proteins and blocks their GTP activation, thereby inhibiting the downstream MAPK and AKT signaling pathways. ADT-1004 can be used for the research of pancreatic ductal adenocarcinoma.

Salvianolic acid F is a KRAS inhibitor, especially for KRAS G12D. Salvianolic acid F inhibits NF-kB, MMP-9, and NO simultaneously. Salvianolic acid F inhibits cancer cell growth, invasion, and migration and induces apoptosis via the EP300/PI3K/AKT pathway in vitro. Salvianolic acid F inhibits the growth of KRAS-dependent lung cancer cells via the PI3K/AKT signaling pathway in vivo. Salvianolic acid F can be used in the research of various cancers, including KRAS G12D-driven non-small cell lung cancer (NSCLC) and ovarian cancer.

VVD-442 is an inhibitor targeting PI3Kα. VVD-442 covalently binds to Cys242 in the RAS-binding domain of PI3K p110α, induces conformational changes, and disrupts the interaction between PI3K p110α and RAS proteins. VVD-442 also blocks RAS-mediated PI3K activation. VVD-442 can be used in research related to RAS-mutant cancers and HER2-overexpressing cancers.
