Anticancer Activity of Extracts in Different Cancer Cells.

BACKGROUND

The arrival of large quantities of in the Mexican Caribbean Sea has generated major environmental, health and economic problems. Although has been used in the generation of some commercial products, few studies have described its possible applications as a source of compounds with anticancer activity.

OBJECTIVE

This study aimed to evaluate the antiproliferative effects of different extracts on various cancer cell lines. Furthermore, LC/QTOF-MS was used to identify the compounds related to the antiproliferative effect.

METHODS

First, determination of the seaweed was performed, and dichloromethane, chloroform and methanol extracts were obtained. The extracts were evaluated for their antiproliferative effects by MTT in breast (MDAMB- 231 and MCF-7), prostate (DU-145), lung (A549) and cervical (SiHa) cancer cell lines. Finally, LC/QTOFMS identified the compounds related to the antiproliferative effect.

RESULTS

The authentication showed as the predominant species. The extracts of dichloromethane and chloroform showed an antiproliferative effect. Interestingly, the fractionation of the chloroform extract showed two fractions (FC1 and FC2) with antiproliferative activity in MDA-MB-231, SiHa and A549 cancer cell lines. On the other hand, three fractions of dichloromethane extract (FD1, FD4 and FD5) also showed antiproliferative effects in the MDA-MB-231, MCF-7, SiHa and DU-145 cancer cell lines. Furthermore, LC/QTOF-MS revealed the presence of eight major compounds in FC2. Three compounds with evidence of anticancer activity were identified (D-linalool-3-glucoside, (3R,4S,6E,10Z)-3,4,7,11-tetramethyl-6,10-tridecadienal and alpha-tocotrienol).

CONCLUSION

These findings showed that extracts are a possible source of therapeutic agents against cancer and could act as scaffolds for new drug discovery.
