  Novel Thieno[2,3-d][1,3]oxazin-4-ones as Inhibitors of Human Leukocyte Elastase

  摘要：

  A series of thieno[2,3-d][1,3]oxazin-4-ones was synthesized and evaluated in vitro for inhibitory activity toward human leukocyte elastase. New synthetic routes to 2-alkoxy-, 2-alkylthio-, and 2-sec-amino-substituted derivatives are reported. This study demonstrates the versatility of 2-aminothiophenes prepared by Gewald reaction as a synthetic entry to serine protease-inhibiting, fused 1,3-oxazin-4-ones. Introduction of ethoxy, n-propoxy, and ethylthio groups at C-2 delivered the most potent inhibitors of this series with K-i values lower than 11 nM. Kinetic studies and product analyses revealed the formation of acyl-enzymes as a result of the attack of the active site serine at the carbon C-4 and subsequent deacylation. This mode of action is similar to the inhibition of serine proteases by 4H-3,1-benzoxazin-4-ones. Replacement of the benzene ring in benzoxazinones by a (substituted) thiophene led to improved hydrolytic stability and retained inhibitory potency.

  The Facile Synthesis of 2-Aminothieno[2,3-d][1,3]thiazin-4-ones, in Some Cases 5,6-Anellated The cyclization of ethyl 2-thioureidothiophene-3-carboxylates is known to give 2-thioxothieno[2,3-d]pyrimidin-4-ones not only under basic conditions but also upon treatment with ethanolic hydrochloric acid. On the other hand, we have found that ethyl 2-thioureidothiophene-3-carboxylates 1 on treatment with concentrated sulphuric acid, polyphosphoric acid or anhydrous perchloric acid undergo cyclocondensation to give 2-aminothieno[2,3-d][1,3]thiazin-4-ones 2a-2r. Reaction of 2 with phosphorus (V) sulfide yielded the thieno[2,3-d][1,3]thiazine-4-thiones 3b and 3c; ring cleavage of the aminothienothiazinones 2k, 2m, 2n with diluted sodium hydroxide gave the 2-thioureidothiophene-3-carboxylic acids 5k, 5m, 5n, respectively.

• Aromatic 2-(Thio)ureidocarboxylic Acids As a New Family of Modulators of Multidrug Resistance-Associated Protein 1: Synthesis, Biological Evaluation, and Structure−Activity Relationships

  Four series of aromatic carboxylic acids were prepared with a urea or thiourea moiety at the neighboring position to the carboxyl group and benzene or thiophene as aromatic scaffold. Using a calcein AM assay, these compounds were evaluated as inhibitors of multidrug resistance-associated protein I (MRP1) and selected compounds were examined toward P-glycoprotein (P-gp) as well as breast cancer resistance protein (BCRP) to assess selectivity for MRP1. Two 2-thioureidobenzo[b]-thiophene-3-carboxylic acids (48, 49) were identified as particularly potent inhibitors of MRP1, with IC50 values of around 1 mu M. The structural features of this new family or nontoxic MRP1 inhibitors include a (thio)urea disubstituted with preferentially two alkyl groups at the terminal nitrogen and an additional fused aromatic ring.
