title: Induction of interferon in murine bone marrow-derived macrophage cultures by 10-carboxymethyl-9-acridanone.
abstract: 10-Carboxymethyl-9-acridanone (CMA) induced high titers of interferon (IFN) in murine leukocyte cultures. Thymocytes, lymph node, spleen and peritoneal exudate cells responded to CMA with IFN production. Pure macrophages derived from the bone marrow were the most efficient producers of CMA-induced IFN. The yields of IFN-alpha, beta in the macrophage supernatants depended on the concentration of the inducer and titers up to 3000 IU/ml were measured after exposure to the optimal dose (500 micrograms/ml). CMA was found to be the first low molecular weight compound that induced in vitro titers of IFN nearly as high as obtained after exposure to Newcastle disease virus, which is one of the most potent interferon inducers.
