5-(3-Nitrophenyl)-1H-pyrazole-3-carboxylic acid is a molecule that inhibits the proliferation of cancer cells in vitro. This compound has been shown to inhibit the growth of human breast cancer cells in culture, with IC50 values of 7.8 µM for MCF-7 and 5.6 µM for A549 cells. It also inhibits cell growth in MDA-MB231 cells, which are human breast carcinoma cells, with IC50 values of 4.5 µM for MCF-7 and 2.4 µM for A549 cells. The mechanism by which this drug inhibits cancer cell proliferation is not clear but may be due to its ability to interfere with DNA synthesis or protein synthesis.
