1. PM02734, a new marine-derived antitumoral compound, has rapid effects on membrane integrity and permeability in tumor cells .
Actividad del Irvalec en la Membrana de las Celulas Tumorales :
Altogether, these effects reflect a severe membrane damage caused by the drug. Interestingly, cell membrane damage was observed only after reaching a threshold concentration of around 3 µM. Similar results were observed with HeLa cervix adenocarcinoma and Hep-G2 hepatocarcinoma cells. Together, these results indicate that PM02734 may exert its potent cytotoxic activity by inducing rapid and severe membrane damage.

2. Characterization of genetic factors associated with sensitivity to Irvalec, a novel marine-derived compound
Estudio Comparativo entre varios Farmacos para evaluar cual es el Más Potente Inhibidor de ERB-B..... queda Claro que el más Potente es Nuestro Irvalec :
*.- Antiproliferative effects of Irvalec, lapatinib, gefitinib, erlotinib, cetuximab and trastuzumab were evaluated in a panel of colon (HT29, HCT116, Colo205, HCC2998), breast (MCF7, MDA-MB-435, SKBR3, ZR-75-1), ovarian (OVCAR3, IGROV1), lung (Hop62, Hop92), prostate (PC3, DU145), Head&Neck (SCC61, SQ20B, HEP2), and pancreatic (MiaPaCa2, CAPAN1) cancer cell lines using the MTT assay. Expression of Erb-B1, 2, 3 and 4 was evaluated using quantitative RT-PCR.
*.- Conclusions:
Irvalec displays an original cytotoxicity profile, being a more potent inhibitor of cell proliferation than other Erb-B inhibitors in a large panel of human cancer cell lines. Activating mutations of KRAS and EMT were observed in cells resistant to Irvalec. Our data suggest that Erb-B2-4 play a role in sensitivity to Irvalec requiring further investigations.
