22-(4′-py)-JA, a semisynthetic derivative of junamycin A isolated from the Thai blue sponge (Xestospongia sp.), exhibits antimetastatic properties by inhibiting the AKT mTOR p70S6K signaling pathway. It also impedes tumor cell invasion and angiogenesis in human umbilical vein endothelial cells (HUVEC), while suppressing the expression of metalloproteinases (MMP-2 and MMP-9), hypoxia-inducible factor 1α (HIF-1α), and vascular endothelial growth factor (VEGF). Its potent anticancer activity is particularly noted against non-small cell lung cancer (NSCLC) [1].
