1.	Neoplasms (Cancer) 09/01/2008 - "Our data show that spongistatin 1 represents a promising novel therapeutic agent for the treatment of leukemic tumor cells especially in the clinically highly relevant situation of chemoresistance due to overexpression of XIAP." 04/01/2013 - "Toward a more step-economical and scalable synthesis of spongistatin 1 to facilitate cancer drug development efforts." 09/01/2011 - "The marine natural product (+)-spongistatin 1 is an extremely potent growth inhibitory agent having activity against a wide variety of cancer cell lines, while exhibiting low cytotoxicity against quiescent human fibroblasts. " 09/01/2010 - "Spongistatin 1 significantly reduced tumor growth, which correlates with a strong apoptosis induction (DNA-fragmentation) and long-term effects on clonogenic survival of pancreatic tumor cells (L3.6pl) in vitro. " 09/01/2008 - "In apoptosis-resistant leukemic tumor cells overexpressing XIAP, spongistatin 1 effectively causes cell death and potentiates cell death induction by other apoptosis-promoting factors that might be caused by spongistatin 1-mediated degradation of XIAP. "
2.	Dehydration (Water Stress) 07/07/2005 - "Two structural analogues were also prepared and evaluated as growth inhibitory agents against a range of human tumour cell lines, including Taxol-resistant strains, alongside altohyrtin A and paclitaxel (Taxol), revealing that dehydration in the E-ring is tolerated and results in enhanced cytotoxicity (at the low picomolar level), whereas the presence of the full C44-C51 side-chain appears to be crucial for biological activity." 02/21/2003 - "Simplified analogues of the potent antimitotic marine macrolide spongistatin 1/altohyrtin A were synthesised and evaluated as growth inhibitory agents against a range of human tumour cell lines, including Taxol-resistant strains, revealing that E-ring dehydration leads to enhanced cytotoxicity at the low picomolar level while truncation of the side-chain at C46 results in a drastic decrease in activity."
3.	Prostatic Neoplasms (Prostate Cancer) 09/01/2011 - "Consistent with a microtubule-targeting mechanism of action, (+)-spongistatin 1 causes mitotic arrest in DU145 human prostate cancer cells. "

5.	Neoplasm Metastasis (Metastasis) 09/01/2010 - "The marine compound spongistatin 1 targets pancreatic tumor progression and metastasis." 09/01/2010 - "Taken together, spongistatin 1 not only proved to be a potent experimental drug but also served as a chemical tool to examine the role of the antiapoptotic protein Bcl-2 in pancreas carcinoma, thereby supporting the hypothesis of a link between apoptosis signaling and metastasis."
