by chemical synthesis and evaluated as inhibitors of cathepsins L and B. The most promising inhibitors from this group are selective for cathepsin L and demonstrate IC50 values in the low nanomolar range. In nearly all cases, the thiochromanone sulfide analogues show superior inhibition of cathepsin L as compared to their corresponding thiochromanone sulfone derivatives. Without exception, the compounds
通过化学合成制备了一系列36个主要在C-6位官能化的包含硫代苯并二氢吡喃酮分子骨架的thiosemicarbazone类似物,并将其评估为组织蛋白酶L和B的抑制剂。该组中最有希望的抑制剂对组织蛋白酶L具有选择性,并显示出IC50值在低纳摩尔范围内。在几乎所有情况下,硫代苯并二氢吡喃酮硫化物类似物均比其相应的硫代苯并二氢吡喃酮砜衍生物具有更好的组织蛋白酶L抑制作用。毫无例外,所评估的化合物对组织蛋白酶B无活性(IC50> 10000 nM)。最有效的组织蛋白酶L抑制剂(IC50 = 46 nM)被证明是6,7-二氟类似物4。小分子已知的结构-活性关系,
