Cytotoxicity effects of calix[4]arenes. Cell viability of HUVEC,
fibroblasts, and human ovarian carcinoma (MA148) and lung carcinoma (A549)
cells, as well as murine endothelial (2H11), fibrosarcoma (FSAII), mammary
carcinoma (SCK), and melanoma (B16F10) cells, was measured in the absence or
presence of various concentrations of calixarenes. Cell viability and survival
was assessed by colorimetric analysis as described in the
“Experimental”
