22-(4′-py)-JA
22-(4′-py)-JA is a semisynthetic derivative of junamycin A (JA) that can be isolated from the Thai blue sponge (Xestospongia sp.). 22-(4′-py)-JA has antimetastatic activity and can inhibit AKT/mTOR/p70S6K signaling. 22-(4′-py)-JA inhibits tumor cell invasion and tube formation in human umbilical vein endothelial cells (HUVEC), downregulates metalloproteinases (MMP-2 and MMP-9), hypoxia-inducible factor 1α (HIF-1α) and vascular endothelial growth factor (VEGF). 22-(4′-py)-JA has potent anticancer activity against non-small cell lung cancer (NSCLC)[1].
