nsc-4347 and Carcinoma--Squamous-Cell

The objective of the present study was to evaluate the action of the crude hydroalcoholic extract of Piper cubeba fruits and isolated lignans (cubebin, dihydrocubebin, ethylcubebin, hinokinin and methylcubebin) on head and neck cancer cells. We evaluated the influence of the Piper cubeba extract and isolated lignans (10, 50 e 100 μg/mL) for 4, 24, 48 and 72 h, in the larynx (Hep-2) and oral (SCC-25) squamous cell carcinoma cells and normal fibroblasts, on morphology, cell proliferation and migration, cytotoxicity, genotoxicity and gene and protein expression (PTGS2, PTGER3, PTGER4, MMP2, MMP9). The results showed that the P. cubeba extract and different lignans do not alter the cellular morphology, but decrease cell proliferation and migration, have low cytotoxic and genotoxic effects, probably due to the alteration of the expression of genes and proteins involved with inflammatory process. From these data, we can conclude that the lignans cubebin and methylcubebin had a greater effect on head and neck cancer cells in the antiproliferative, antimigratory and genotoxic action, and could be the target of the development of new therapies including possible new drugs as a therapeutic resource for the treatment of head and neck cancer due to its immense range of biological properties.

Oral squamous cell carcinoma (OSCC) is one of the ten most common types of cancer worldwide. Plants of the genusPiper are used in traditional medicine to treat cancer, and they have a vast diversity of phytochemicals with cytotoxic potential. Purpose and Study Design: In this work, we analyzed the cytotoxic and selective potential of extracts and semipurified fractions of Piper mollicomum (PM), Piper truncatum (PT), Piper cernuum (PC), Piper arboreum (PA), and Piper cabralanum (PCa) using three different OSCC cell lines (SCC4, SCC9 and SCC25), and we measured their in vivo toxicities and conducted chemical analyses of their active fractions.. PC-L-D demonstrated great potential for further development as an anticancer drug and could be the key to developing more effective and less toxic therapies against oral cancer.
