Marine drugs for cancer: surfacing biotechnological innovations from the oceans

This review will discuss the contributions of marine natural molecules, a source only recently found to have pharmaceutical prospects, to the development of anticancer drugs. Of the seven clinically utilized compounds with a marine origin, four are used for the treatment of cancer. The development of these drugs has afforded valuable knowledge and crucial insights to meet the most common challenges in this ende...

Chromomycin A2 induces autophagy in melanoma cells

The present study highlights the biological effects of chromomycin A2 toward metastatic melanoma cells in culture. Besides chromomycin A2, chromomycin A3 and demethylchromomycin A2 were also identified from the extract derived from Streptomyces sp., recovered from Paracuru Beach, located in the northeast region of Brazil. The cytotoxic activity of chromomycin A2 was evaluated across a panel of human tumor cell ...

Estaurosporinas de Eudistoma vannamei : química e bioatividade

Eudistoma vannamei Millar, 1977 is an endemic tunicate from the northeastern Brazilian coast, widely distributed over the rocky beaches of Ceará State. Previously, the crude extract showed an interesting bioactivity profile. Bioassay-guided fractionation yielded a highly cytotoxic 1:1 mixture identified as two novel staurosporine derivatives, 2-hydroxy-7-oxostaurosporine (I) and 3-hydroxy-7-oxostaurosporine (II...

Bioprospecção de substâncias com potencial antitumoral em ascídias do litoral c...

The study, initially, evaluated the citotoxity of the hydro-alcoholic extracts of the 10 most abundant ascidian species from the coast of Ceará (Brazil), through the utilization of the following methods: brine shrimps lethality assay; development inhibition of sea urchin eggs; hemolytic potential, and inhibition of in vitro tumor cell growth. In three of the four assays performed, the Eudistoma vannamei species...
