  Evaluation of 8-Arylsulfanyl, 8-Arylsulfoxyl, and 8-Arylsulfonyl Adenine Derivatives as Inhibitors of the Heat Shock Protein 90

  摘要：

  Hsp90 is a chaperone protein with important roles in maintaining transformation and in elevating the survival and growth potential of cancer cells. Currently there is an increasing interest in developing inhibitors of this protein as anticancer therapeutics. One of such inhibitors, the purine-scaffold class, has been reported to be potent and selective against Hsp90 both in vitro and in vivo models of cancer. Here, a series of 8-arylsulfanyl, -sulfoxyl, and -sulfonyl adenine members of the purine class was synthesized and evaluated as inhibitors of the chaperone. The structure-activity relationship and selectivity for tumor Hsp90 of compounds within the series is presented. Our results suggest that 8-arylsulfanyl adenine derivatives are good inhibitors of chaperone activity, whereas oxidation of the sulfides to sulfoxides or sulfones leads to compounds of decreased activity. The study identifies derivative 11v as the most potent Hsp90 inhibitor of the purine-scaffold series published to date (EC50 = 30 nM), and also as the compound of this class with highest selectivity for tumor vs normal cell Hsp90 (700 to 3000-fold). Most rewardingly, this work has allowed for the identification of Hsp90 inhibitors with selective affinities for Hsp90-client protein complexes, derivatives that may represent useful pharmacological tools in dissecting Hsp90-regulated processes.

• Imidazopyridine- and Purine-Thioacetamide Derivatives: Potent Inhibitors of Nucleotide Pyrophosphatase/Phosphodiesterase 1 (NPP1)

  Nucleotide pyrophosphatase/phosphodiesterase 1 (NPP1) belongs to the family of ecto-nucleotidases, which control extracellular nucleotide, nucleoside, and (di)phosphate levels. To study the (patho)physiological roles of NPP1 potent and selective inhibitors with drug-like properties are required. Therefore, a compound library was screened for NPP1 inhibitors using a colorimetric assay with p-nitrophenyl

  核苷酸焦磷酸酶/磷酸二酯酶1（NPP1）属于胞外核苷酸酶家族，可控制细胞外核苷酸，核苷和（di）磷酸盐的水平。为了研究具有药物样特性的NPP1强效和选择性抑制剂的（病理）生理作用。因此，使用比色测定法以对硝基苯基5'-胸苷单磷酸酯（p -Nph-5'-TMP）作为人工底物，筛选化合物库中的NPP1抑制剂。这导致发现2-（3 H-咪唑并[4,5 - b ]吡啶-2-基硫基）-N-（3,4-二甲氧基苯基）乙酰胺（5a）为具有K i的命中化合物。值为217 nM。随后的结构-活性关系研究导致了嘌呤和咪唑并[4,5- b ]吡啶类似物的开发，用p -Nph-5'-进行测定具有高抑制力（K i值分别为5.00 nM和29.6 nM）。以TMP为底物。出乎意料的是，与ATP作为底物相比，测试时这些化合物的效力明显较低，K i值在低微摩尔范围内。对原型抑制剂的抑制机理进行了研究，发现该抑制剂与两种底物都具有竞争性。
