Ten novel disulfide derivatives containing 1,3,4-thiadiazole moiety were synthesized from appropriate thiols, thiourea and 2-amino-5-mercapto-1,3,4-thiadiazole via two steps reactions. All compounds were characterized by IR, 1H NMR, ESI-MS techniques and elemental analysis. The in vitro antiproliferative activities of target compounds against SMMC-7721 (human liver cancer cell), MCF-7 (human breast cancer cell) and A549 (human lung cancer cell) cells were evaluated by CCK-8 assay. The bioassay results demonstrated that most of the tested compounds showed better antiproliferative activities, and exhibited stronger effects than positive control 5-fluorouracil (5-FU) against various cancer cell lines. Particularly, n-propyl (2-amino-1,3,4-thiadiazol-5-yl)disulfide (3b) and n-butyl (2-amino-1,3,4-thiadiazol-5-yl)disulfide (3d) displayed highly effective antiproliferative effects against SMMC-7721 cells with IC50 values of 1.68 and 1.93 μmol/L. 4-Chlorobenzyl (2-amino-1,3,4-thiadiazol-5-yl)disulfide (3i) exhibited significant antiproliferative activities against MCF-7 cells with IC50 value of 1.78 μmol/L, and revealed the best inhibitory effect against A549 cells with IC50 value of 4.04 μmol/L.
