Disclosed herein are novel motuporamine compounds that act as anti-metastatic agents with low toxicity and high anti-migration activity. The non-toxic, anti-metastatic agents may be given to patients with potential or actual metastatic cancers, such as pancreatic cancers, alone in combination with known and/or new therapies to help block the growth and spread of tumor(s)..

The motuporamines isolated from the sea sponge Xestospongia exigua are of biological interest because of their unique antimigration and antiangiogenic properties. Key bioactive features were found to be a saturated 15-membered heterocycle and a norspermidine motif. This paper describes new analogues that modulate the cytotoxicity of this compound class and have enhanced antimigration properties. By movement of the polyamine chain outside the ring, new carbocycles were discovered that doubled the antimigration potency and reduced compound toxicity by 133-fold. Mice injected with metastatic human L3.6pl pancreatic cancer cells demonstrated significant reduction in liver metastases when treated with N-1-(3-aminopropyl)-N-3-(cyclopentadecylmethyl)propane-1,3-diamine compared with dihydromotuporamine C. Significant changes in specific ceramide populations (N16:0 and N22:1) were noted in L3.6pl cells treated with dihydromotuporamine C but not for the cyclopentadecylmethylnorspermidine derivative, which had lower toxicity. Both compounds gave increased levels of specific low molecular weight sphingomyelins, suggesting that they may act upon sphingomyelin processing enzymes.
