Some disulfides have previously been shown to possess antifungal and/or antileukaemic activity. Importantly, this cytotoxicity can be selective. We have previously shown that a subset of these compounds does not block the proliferative potential of normal, non-transformed cells. Based on these results and proposed mechanisms of action, a new set of structurally modified organosulfur compounds, including α-substituted disulfides and a thiosulfonate ester, have been prepared and evaluated for their potential as antileukaemic agents. Compounds were screened for antiproliferative activity against a panel of human cells derived from acute lymphocytic and acute myelogenous leukaemia, as well as non-transformed cells. We have identified five new disulfides and a thiosulfonate that can trigger tumour cells to undergo cell death by an apoptotic mechanism in a sensitive and specific manner.
Synthesis and antifungal testing of 2,4,5,7,9-pentathiadecane 9,9-dioxide has established that the absence of oxygen atoms on S2 significantly attenuates fungitoxicity in accord with our earlier proposal. Attempts to convert that compound into dysoxysulfone led to the discovery of a novel oxidative conversion of unsymmetrical γ-sulfonyl disulfides into the corresponding symmetrical γ-sulfonyl disulfides.
