We investigated the effects of the recently synthetized NO donating agent GIT-27NO on the growth of human androgen independent and androgen dependent PC3 and LnCap cells xenografted in nude mice. We also tested the effects of GIT-27NO in the preclinical model of cell-mediated immunoinflammatory hepatitis that can be induced in mice by Concanavalin A (ConA) and that has been shown to benefit from the treatment with NO donating agents such as NO-aspirin. In agreement with in vitro data showing dose-dependent reduction of PO and LnCap cell viability with GIT-27NO, the i.p. treatment of mice xenografted with either of these cells with GIT-27NO significantly inhibited their growth as compared to the mice-treated with its vehicle. In addition, GIT-27NO given -24 and -1 h prior to e.v. challenge with 20 mg/kg ConA significantly suppressed the increase of transaminases that occurred 8 h after challenge in the control mice that received the vehicle. In addition, relative to these latter groups of mice, the histological signs of inflammatory hepatitis were markedly reduced in ConA-challenged mice that received GIT-27NO. In the hepatitis model, GIT-27NO was equally effective in preventing ConA-induced hepatitis regardless of whether it was administered intra peritoneally or per os. These data confirm that Grr-27NO is a powerful anticancer agent also endowed with pharmacological properties to prevent the development of cell-mediated murine immunoinflammatory hepatitis.
