  Nonpeptidic Inhibitors of Human Leukocyte Elastase. 2. Design, Synthesis, and in vitro Activity of a Series of 3-Amino-6-aryl-2-oxopyridyl Trifluoromethyl Ketones

  摘要：

  A series of potent nonpeptidic inhibitors of the enzyme human leukocyte elastase (HLE) is reported. These inhibitors contain a 3-amino-2-pyridone ring as a central template in which the pyridone carbonyl and 3-position NH group are thought to form important hydrogen bonding interactions with the Val-216 residue of HLE. Substitution of the 6-position of the pyridone ring by various alkyl and aryl groups was found to afford increases in the in vitro potency of these inhibitors. A 6-position phenyl group, compound 10f, was found to result in a large increase in binding affinity, which was not obtained when the phenyl group was placed in either the 4- or 5-position of the molecule. Compound 10f was found to have good selectivity for HLE over other proteolytic enzymes, with the exception of bovine pancreatic chymotrypsin (BPC). Substitution of the 6-phenyl group in these molecules was found to decrease binding affinity for BPC without adversely affecting affinity for HLE.

  人白细胞弹性蛋白酶的非肽抑制剂。1.含吡啶酮的抑制剂的设计与合成。

  摘要：

  人白细胞弹性蛋白酶（HLE）是嗜中性粒细胞产生的一种丝氨酸蛋白酶，与肺气肿和囊性纤维化等疾病有关。HLE抑制剂在这些疾病中可能具有治疗价值。结合三肽三氟甲基酮（TFMK）抑制剂2的HLE活性位点模型是由HLE和猪胰弹性蛋白酶的X射线结构创建的。对模型的分析表明，三肽具有较好的结合构象，并且可能与酶发生重要的相互作用。该信息用于辅助设计一系列新颖的含吡啶酮的非肽类HLE抑制剂，例如2- [3-[[（（苄氧基）羰基]氨基] -2-氧-1,2-二氢-1-吡啶基] -N-（3,3,3-三氟-1-异丙基-2-氧丙基）乙酰氨基化物（5b）（Ki = 280 +/- 78 nM）。活性位点模型的检查表明，在吡啶酮环的5位上的苄基取代基可能通过与酶S2口袋形成亲脂性相互作用而提高效能。一系列5-苄基吡啶酮TFMK的合成和生物学评估为这一主张提供了证据。对模型的进一步分析表明，在吡啶酮环的3-氨基上被氢键受

  Using molecular modeling and the information derived from X-ray crystal structures of human neutrophil elastase (HNE) and porcine pancreatic elastase (PPE) complexed to peptidic ligands, we have developed a new series of nonpeptidic inhibitors of HNE, the pyridopyrimidine trifluoromethyl ketones (TFMKs). These bicyclic inhibitors were designed to extend the concept of the related pyridone trifluoromethyl ketones by incorporating a rigidly positioned carbonyl group to participate in a hydrogen bonding interaction with the backbone NH groups of Gly-218 and Gly-219 of the enzyme. In addition, the pyrimidine ring serves as a scaffold to vector substituents toward the S-5-S-4 subsites of the enzyme's extended binding pocket. Furthermore, the heteroatoms of the pyrimidine ring generally increase the aqueous solubility of the pyridopyrimidines relative to pyridone TFMKs. Pyridopyrimidine TFMKs containing a 6-phenyl substituent afforded potent inhibitors of elastase, and several inhibitors from this class of compounds possessed aqueous solubilities of > 0.1 mg/mL and K-i values of less than or equal to 10 nM.
