18-Deoxyherboxidiene

18-Deoxyherboxidiene (RQN-18690A) is a potent angiogenesis inhibitor. 18-Deoxyherboxidiene targets SF3b, a spliceosome component that is a subcomplex of the U2 small nuclear ribonucleoprotein (snRNP) in the spliceosome. 18-Deoxyherboxidiene inhibits the migration and tube formation of human umbilical vein endothelial cells (HUVECs) without significant cell toxicity. 18-Deoxyherboxidiene has the potential for cancer research.
