  Synthesis of (1,3,4-thiadiazol-2-yl)-acrylamide derivatives as potential antitumor agents against acute leukemia cells

  摘要：

  A lead compound with the (1,3,4-thiadiazol-2-yl) acrylamide scaffold was discovered to have significant cytotoxicity on several tumor cell lines in an in-house cell-based screening. A total of 60 derivative compounds were then synthesized and tested in a CCK-8 cell viability assay. Some of them exhibited improved cytotoxic activities. The most potent compounds had IC50, values of 1-5 mu M on two acute leukemia tumor cell lines, i.e. RS4;11 and HL-60. Flow cytometry analysis of several active compounds and detection of caspase activation indicated that they induced caspase-dependent apoptosis. It was also encouraging to observe that these compounds did not have obvious cytotoxicity on normal cells, i.e. IC50 > 50 mu M on HEK-293T cells. Although the molecular targets of this class of compound are yet to be revealed, our current results suggest that this class of compound represents a new possibility for developing drug candidates against acute leukemia.

  我们报道首次开发三钠的多金属氧酸盐-lacunary（多金属氧酸盐）8 H [A-PW 9 ö 34 ]·7H 2 O和Na 8 H [B-PW 9 ö 34 ]·19H 2 O（钠-A-PW 9和Na-B-PW 9）是高选择性和高效的均相Lewis碱催化剂，用于Knoevenagel缩合，各种醛和酮的氰基硅烷化以及在25°C下于温和条件下合成苯并恶唑衍生物。由于Na-A-PW 9和Na-B-PW 9由于没有显示出特征性的孔隙率，建议催化反应不仅在表面和界面上进行，而且在本体相中进行。催化剂可以容易地回收并重复使用至少六次而不会明显降低催化活性，并且催化剂的结构在循环后保持不变。Na-A-PW 9和Na-B-PW 9的多相催化剂易于制备，高效且可重复使用，具有进一步应用的巨大潜力。
