The present invention relates to a pharmaceutical composition for inhibiting angiogenesis and a novel sulfonyl amide derivative compound which can be useful for the prevention or treatment of angiogenesis-related diseases or disorders. Since the compound used as an active ingredient in the pharmaceutical composition of the invention is specifically bound to UQCRB and inhibits biological functions thereof, apoptosis is not induced and angiogenic responses are inhibited. Therefore, the compound used as an active ingredient in the pharmaceutical composition of the invention can be useful as an effective and safe angiogenesis inhibitory agent.

Recently we identified a novel therapeutic target and small molecule for regulating angiogenesis. Our study showed that ubiquinol-cytochrome c-reductase binding protein (UQCRB) of the mitochondrial complex III plays a crucial role in hypoxia-induced angiogenesis via mitochondrial reactive oxygen species (ROS) mediated signaling. Herein, we developed new synthetic small molecules that specifically bind to UQCRB and regulate its function. To improve the pharmacological properties of 6-((1-hydroxynaphthalen 4-ylamino)dioxysulfone) 2H naphtho[1,8-bc]thiophen-2-one (HDNT), a small molecule that targets UQCRB, a series of HDNT derivatives were designed and synthesied. Several derivatives showed a significant increase in hypoxia inducible factor 1 alpha (HIF-1 alpha) inhibitory potency. compared to HDNT. The compounds bound to UQCRB and suppressed mitochondrial ROS-mediated hypoxic signaling, resulting in potent inhibitor of angiogenesis without inducing cytotoxicity. Notably, one of these new derivatives significantly suppressed tumor growth in a mouse xenograft model. Therefore, these mitochondrial UQCRB modulators could be potential leads for the development of novel antiangiogen agents.
Novel Arylsulfoanilide−Oxindole Hybrid as an Anticancer Agent That Inhibits Translation Initiation
Structure-activity relationship studies of substituted arylsulfoanilides as antiproliferatives, which are mediated by the partial depletion of intracellular Ca2+ stores, resulted in the identification of compounds with micromolar activity against lung cancer cells in a growth inhibition assay. Incorporating the substitution pattern of the best arylsulfoanilides onto the 3-phenyloxindole scaffold resulted in a potent arylsulfoanilide-oxindole hybrid, 27. Compound 27 inhibits cancer cell growth by partial depletion of intracellular Ca2+ stores and phosphorylation of eIF2alpha.
