CD BioGlyco has many years of experience in the scalable production of Marine Biomolecules, including Marine Carbohydrates, Marine Glycoproteins, Marine Lectins, Marine Glycosides, and Marine Glycolipids. In this service, CD BioGlyco ensures high purity and yield of crambescidins which are crucial marine glycoproteins from sponges for pharmaceutical and research applications. Marine sponges (phylum Porifera) stand as a paramount reservoir of novel bioactive compounds among marine organisms, consistently yielding over 200 newly documented compounds annually. These organisms synthesize a diverse array of secondary metabolites primarily for defensive purposes, safeguarding against threats posed by competitors, predators, and pathogens. Moreover, sponges often harbor microbial symbionts, recognized as pivotal contributors of bioactive agents.
We mainly explore the extraction methods of the bioactive compounds derived from the various sponges, leading to the identification of a rich spectrum of crambescidin-type guanidine alkaloids. Our researchers undertake comprehensive efforts encompassing isolation, purification, structural elucidation, purity determination, and biological activity assay of these crambescidins.
Our research team is very professional in organic synthesis, therefore we provide the total synthesis, isolation, purity, and structural characterization of the crambescidin and its derivatives.

Results: In this study, extracts from twenty marine sponges collected off the coast of Western Australia were screened for cytotoxic activity against triple-negative breast cancer (TNBC) cells. A highly active extract from the sponge Monanchora viridis was selected for bioactivity-guided fractionation. Through various purification processes, authors successfully isolated a potent cytotoxic compound, identified as crambescidin 800. Crambescidin 800 demonstrated significant cytotoxic effects across a range of breast cancer cell lines, with TNBC and luminal models showing the highest sensitivity. Crambescidin 800 decreased cell viability and caused cell cycle arrest at the G2/M phase in T11 and SUM159PT cells. Moreover, crambescidin 800 lowered the expression of proliferation-associated CDKs like cyclin D1, CDK4, and CDK6, while upregulating CDK inhibitors such as p21 at the protein level. Crucially, crambescidin 800 inhibited the phosphorylation of the Akt/mTOR, MAPK, and NF-κB pathways, which are implicated in tumor relapse and metastasis, leading to programmed cell death in T11 and SUM159PT TNBC cells. Overall, their findings suggest that crambescidin 800 has the potential to target multiple signaling pathways in TNBC cells, which are involved in cell survival and resistance to chemotherapy. Further research is needed to determine whether crambescidin 800 exhibits in vivo activity against TNBC, potentially paving the way for new anticancer therapies.
