Icrucumab (Anti-VEGFR1/FLT1 Reference Antibody; IMC-18F1) is an IgG1 antibody inhibitor targeting VEGFR-1/FLT1 with anti-tumor activity. By blocking ligand-dependent phosphorylation and downstream signal transduction, Icrucumab reduces the activities of MAPK and Akt in breast cancer xenograft models, inhibits the proliferation and invasion of VEGFR-1-positive tumor cells, and reverses the conversion of M1 macrophages to the pro-tumor M2-like phenotype. Icrucumab also inhibits tumor cell proliferation, promotes apoptosis, and effectively suppresses tumor growth through direct targeting of tumors and host support mechanisms. In addition, Icrucumab exhibits a synergistic effect when combined with chemotherapeutic agents, and it is used in research related to various cancers including advanced solid malignancies, thyroid cancer, melanoma, and lung cancer.

SSGJ-707 (PF-08634404) is a bispecific antibody targeting VEGF and PD-1. SSGJ-707 exerts dual anti-tumor effects by neutralizing VEGF and blocking the PD-1 signaling pathway. SSGJ-707 can be combined with platinum-based chemotherapy to inhibit advanced non-small cell lung cancer (NSCLC), and its inhibitory effect is not limited by PD-L1 expression levels. In the HARMONi-2 trial, the objective response rate of SSGJ-707 correlates with the PD-L1 tumor proportion score, and the incidence of grade ≥3 adverse events is comparable to that of Inetetamab (HY-P99969). SSGJ-707 is being extensively investigated for a variety of malignancies including advanced NSCLC, colorectal cancer and small cell lung cancer.

Raddeanin A is an oleanane-type triterpenoid saponin with oral activity. Raddeanin A inhibits SRC, mTOR, JNK, VEGFR2, NLRP3 inflammasome, Wnt/β-catenin, Wee1, PI3K/AKT signaling pathway, MAPK/ERK signaling pathway, AR-FL, AR-Vs, and downregulates the expression of p-PI3K and p-AKT. Raddeanin A inhibits osteoclast formation, bone resorption, osteolysis, cancer cell invasion, migration, proliferation, angiogenesis and epithelial-mesenchymal transition, while induces apoptosis, cell cycle arrest, ROS production, immunogenic cell death and dendritic cell maturation. Raddeanin A improves blood-retinal barrier function, alleviates inflammation, regulates the tumor microenvironment, and enhances the activity of anti-PD-1 antibody. Raddeanin A is applicable to the research of breast cancer-associated osteolysis, human osteosarcoma, colorectal cancer, glioblastoma, Alzheimer's disease, cholangiocarcinoma, melanoma, non-small cell lung cancer, castration-resistant prostate cancer and multiple myeloma.

Talmapimod (SCIO-469) is an orally active and selective inhibitor of p38α MAPK with an IC₅₀ of 9 nM. Talmapimod inhibits the secretion of inflammatory factors (such as TNFα, IL-1β, IL-6, and VEGF) by suppressing the p38α MAPK pathway, and it also inhibits angiogenesis and osteoclast activation. Talmapimod inhibits the growth of multiple myeloma cells and induces apoptosis. Talmapimod can be used to study various hematological malignancies (such as multiple myeloma, myelodysplastic syndrome).
