  An Efficient and Practical Radiosynthesis of [¹¹C]Temozolomide

  摘要：

  Temozolomide (TMZ) is a prodrug for an alkylating agent used for the treatment of malignant brain tumors. A positron emitting version, [C-11]TMZ, has been utilized to help elucidate the mechanism and biodistribution of TMZ. Challenges in [C-11]TMZ synthesis and reformulation make it difficult for routine production. A highly reproducible one-pot radiosynthesis of [C-11]TMZ with a radiochemical yield of 17 +/- 5% and >= 97% radiochemical purity is reported.

  Recently, we identified a novel class of potent cathepsin L inhibitors, characterized by a thiocarbazate warhead. Given the potential of these compounds to inhibit other cysteine proteases, we designed and synthesized a library of thiocarbazates containing diversity elements at three positions. Biological characterization of this library for activity against a panel of proteases indicated a significant preference for members of the papain family of cysteine proteases over serine, metallo-, and certain classes of cysteine proteases, such as caspases. Several potent inhibitors of cathepsin L and S were identified. The SAR data were employed in docking studies in an effort to understand the structural elements required for cathepsin S inhibition. This study provides the basis for the design of highly potent and selective inhibitors of the papain family of cysteine proteases.

  最近，我们鉴定出一类新型高效组织蛋白酶L抑制剂，其特点是具有硫卡巴脒头部结构。鉴于这些化合物有可能抑制其他半胱氨酸蛋白酶，我们设计并合成了一系列硫卡巴脒类化合物，这些化合物在三个位点上含有多样性元素。该化合物的生物活性鉴定结果显示，它们对木瓜蛋白酶家族的半胱氨酸蛋白酶相较于丝氨酸、金属蛋白酶以及某些类别的半胱氨酸蛋白酶（如胱天蛋白酶）表现出显著的选择性。我们鉴定出了几个高效的组织蛋白酶L和S抑制剂。通过对接研究，我们利用SAR数据来理解实现组织蛋白酶S抑制所需的结构要素。这项研究为设计高度有效且选择性的木瓜蛋白酶家族半胱氨酸蛋白酶抑制剂奠定了基础。
