BPI-9016M is an effective, orally active, and selective dual inhibitor of c-Met and AXL tyrosine kinases. It suppresses tumor cell growth, invasion, and migration of lung adenocarcinoma.
Aspulvinone O is a fungal metabolite that has been found in P. variotti and has antioxidant and anticancer activities.1,2 It scavenges 2,2-diphenyl-1-picrylhydrazyl radicals in a cell-free assay (IC50 = 11.6 μM).1 Aspulvinone O inhibits aspartate transaminase 1 (GOT1; Kd = 3.32 μM) and is cytotoxic to PANC-1, AsPC-1, and SW1990 pancreatic cancer cells (IC50s = 20.54-26.8 μM).2 It reduces the oxygen consumption rate (OCR) and induces apoptosis in SW1990 cells. Aspulvinone O (2.5 and 5 mg/kg) reduces tumor growth in an SW1990 mouse xenograft model.

Chromomycin A2 is an aureolic acid that has been found in several marine actinomycetes and has antibacterial and anticancer activities. Chromomycin A2 inhibits the growth of B. subtilis in an agar diffusion assay. It also inhibits the growth of human SGC7901 gastric cancer, HepG2 hepatocellular carcinoma, A549 lung epithelial adenocarcinoma, HCT116 colon cancer, and COC1 ovarian cancer cells, as well as human umbilical vein endothelial cells (HUVECs; IC50s = 4, 0.5, 3, 5, 5, and 8 nM, respectively). Chromomycin A2 (30 nM) halts the cell cycle in the G0/G1 phase and increases the protein levels of LC3A and LC3B in MALME-3M melanoma cells, indicating that it induces autophagy. It also increases the levels and promoter activity of the autophagic proteins ATG7 and ATG10 and reduces cell viability to 50% in human SCC-11 squamous cell carcinoma cells when used at a concentration of 30 nM.
Antitumor agent-44 (Compound 5n) elicits potent antitumor effects by inducing disruption of mitochondrial homeostasis, cell cycle arrest, and apoptosis in human adenocarcinoma cells. Moreover, Antitumor agent-44 demonstrates significant anti-tumor activity in a lung cancer cell xenograft mice model [1].
