چکیده

Numerous lines of mouse lymphoid tumors (13 of 22 tested) showed, with increased sensitivity, a property of normal mouse splenic lymphocytes, the potential for growth promotion in vitro by specific thiols added to standard culture media. For lymphoma L1210 (V), structure activity relationships were examined; 9 of 30 thiols promoted growth; the most active was alpha-thioglycerol, effective at 0.2 microM. Thiols became oxidized under conditions of tissue culture and had half-lives of less than 8 h. Disulfides of active thiols promoted growth of lymphoma cells. The mitogenic response of splenic lymphocytes to lectins was increased by thiols-disulfides which promoted the growth of lymphoma cells, but the response varied with the mitogen preparation used and under some conditions thiols-disulfides were inhibitory.

Oxidative coupling of thiols to disulfides in solution radiation with Trimethylammonium Fluorochromate(VI), [(CH3)3NH[CrO3F], on Silica Gel

A mild and efficient method for the oxidative coupling of thiols by trimethylammonium fluorochromate(TriMFC) in solution is reported. Trimethylammonium fluorochromate is efficient and new reagent, whichprepares easily and oxidizes thiols to the corresponding disulfides quickly. The reactions perform cleanly andcontrolled to stop at the disulfide stage without over-oxidation side products.
