macrophages, H2S release from FW1256 was apparent over a period of 24h in these cells. Moreover, the effect of FW1256 on TNFα and IL-6 by FW1256 in LPS-stimulated RAW264.7 macrophages was reversed by treatment with the H2S scavenger, vitamin B12a. FW1256 had no cytotoxic effect on LPS-stimulated RAW264.7 macrophages or BMDMs. In vivo, FW1256 administration also reduced IL-1β, TNFα, nitrate/nitrite and PGE2

cell lines compared to the most widely studied H2S donor GYY4137 (1). Herein, we have prepared new thiophosphorus organic H2S donors with different ring sizes and evaluated them in two solid tumor cell lines and one normal cell line. A seven membered ring compound, 17, was found to be the most potent with sub-micromolar IC50s in breast (0.76 μM) and ovarian (0.76 μM) cancer cell lines. No significant
