  Toward the First Class of Suicide Inhibitors of Kallikreins Involved in Skin Diseases

  摘要：

  The inhibition of kallikreins 5 and 7, and possibly kallikrein 14 and matriptase, (that initiates the kallikrein proteolytic cascade) constitutes an innovative way to treat some skin diseases such as Netherton syndrome. We present here the inhibitory properties of coumarin-3-carboxylate derivatives against these enzymes. Our small collection of these versatile organic compounds was enriched by newly synthesized derivatives in order to obtain molecules selective against one, two, three enzymes or acting on the four ones. We evidenced a series of compounds with IC50 values in the nanomolar range. A suicide mechanism was observed against kallikrein 7 whereas the inactivation was either definitive (suicide type) or transient for kallikreins 5 and 14, and matriptase. Most of these potent inhibitors were devoid of cytotoxicity toward healthy human keratinocytes. In situ zymography investigations on skin sections from human kallikrein 5 transgenic mouse revealed significant reduction of the global proteolytic activity by several compounds.

  香豆素作为 XIIa 因子抑制剂：使用基于片段的策略提高效力和选择性

  摘要：

  之前，我们描述了 XIIa 因子的弱香豆素抑制剂，这是人工表面诱导的血栓形成和各种炎症性疾病的有希望的靶标。在这项工作中，我们使用基于片段的药物发现方法来改进我们的香豆素系列。首先，我们筛选了 S1 口袋的约 200 个片段。胰蛋白酶样丝氨酸蛋白酶（例如因子 XIIa）的 S1 口袋高度保守，并且已知驱动大部分缔合能量。通过筛选，我们选择了具有微摩尔活性的片段，并研究了它们对其他丝氨酸蛋白酶的选择性。然后，这些片段被合并到我们的香豆素模板中，从而产生纳摩尔抑制剂。通过质谱法进一步研究了抑制机制，证明了通过形成酰基酶复合物的共价结合。在血浆中测试了最有效的化合物，以评估其在凝血试验中的稳定性和功效。它的血浆半衰期为 1.9 小时，并且对内源性凝血途径比外源性凝血途径具有良好的选择性。

  inhibitory potency toward alpha-CT and HLE. Cycloalkyl esters and amides were found to be essentially inactive on both enzymes. On the opposite, aromatic esters strongly inactivated alpha-CT whereas HLE was less efficiently inhibited with dichlorophenyl ester derivatives (kinact/K(I) = 4000 M(-1) s(-1) for 36). Representative examples of amide, ester, thioester and ketone derivatives were prepared in order

  合成了新型香豆素衍生物，并测试了其对α-CT和HLE的抑制作用。发现环烷基酯和酰胺对两种酶基本上无活性。相反，芳香族酯强烈地使α-CT失活，而二氯苯基酯衍生物对HLE的抑制作用较弱（36的动力学/ K（I）= 4000 M（-1）s（-1））。制备酰胺，酯，硫代酯和酮衍生物的代表性实例，以评估香豆素环与苯基侧链之间的连接的影响。如修饰的胰凝乳蛋白酶的氨基酸分析所示，6-氯甲基衍生物不可逆地使α-CT失活是由于组氨酸残基的烷基化。相反，对HLE的抑制是短暂的。香豆素的内在反应性已使用配体与甲醇-水对之间的亲核反应模型进行了计算。从该计算看来，这些分子表达的抑制能力的差异不能仅通过内酯羰基对亲核攻击的反应性差异来解释。

In this study, a novel CYP activity-based probe was rationally designed and synthesised, demonstrating selective binding of CYP isoforms. The dependence of probe binding upon the presence of NADPH permits the selective detection of functionally active CYP. This allows the detection and analysis

  activity toward bovine alpha-chymotrypsin and human leukocyte elastase. Both series behaved as time-dependent inhibitors of alpha-chymotrypsin, but ester-type coumarins were clearly more efficient than the corresponding amides in inactivating the serine proteinase. The best inactivations were observed with "aromatic" esters, in particular with meta-substituted phenyl esters such as m-chlorophenyl 6-(chlor

  In this work, coumarins were screened on thrombin (THR) and factor Xa (FXa), two of the most promising targets for the development of anticoagulant drugs. This allowed us to highlight compound 30, characterized by a 2,5-dichlorophenyl ester in the 3-position and a chloromethyl moiety in the 6-position, as a very potent THR inhibitor (k(i)/K-I, = 37 000 M-1 s(-1)). Moreover, this compound exhibits good selectivity over FXa (168-fold) and trypsin (54-fold). The mechanism of inactivation was investigated in this series and significantly differs from that previously observed with (x-chymotrypsin. Indeed, the addition of hydrazine on the THR-inhibitor complex promotes a partial induced THR reactivation. This reactivation, confirmed by LC/MS, showed the resurgence of the native THR and a new dihydrazide complex. Docking experiments were then efficiently used to explain the trends observed in the enzymatic assays as well as to corroborate the postulated inhibition mechanism. Finally, the cell permeability of our derivatives was estimated using a computational approach.
