  Excitatory amino-acid receptor agonists. Synthesis and pharmacology of analogues of 2-amino-3-(3-hydroxy-5-methylisoxazol-4-yl)propionic acid

  摘要：

  We have previously proposed the existence of a lipophilic cavity of the 2-amino-3-(3-hydroxy-5-methylisoxazol4-yl)propionic acid (AMPA) receptor recognition site capable of accommodating alkyl substituents of limited size in the 5-position of the isoxazole ring. In order to indirectly elucidate the approximate extent of this proposed cavity we have synthesized and pharmacologically characterized a number of AMPA analogues. For most of these AMPA analogues, a positive correlation between AMPA receptor affinity and agonist effect was observed. The only exception was demethyl-AMPA (8a), which showed relatively high AMPA receptor affinity (IC50 = 0.27 mu M) but remarkably weak agonist potency (EC50 = 900 mu M). Whereas the ethyl analogue of AMPA (Et-AMPA) (IC50 = 0.030 mu M; EC50 = 2.3 mu M) has previously been shown to be slightly more potent than AMPA (IC50 = 0.040 mu M; EC50 = 3.5 mu M), substitutions of a propyl or a butyl group for the methyl group of AMPA to give 8b (IC50 = 0.090 mu M; EC50 = 5.0 mu M) or 8f (IC50 = 1.0 mu M; EC50 = 32 mu M), respectively, result in progressive loss of the AMPA agonist effect. Analogues containing larger groups, such as isopentyl (8e), 1-propylbutyl (8g), 2,2-dimethylpropyl (8h), or benzyl (14) groups, were very weak or totally inactive as AMPA receptor ligands.

  5-取代的3-异恶唑醇的新颖途径。通过酰基麦德鲁姆酸合成的N，O-DiBocβ-酮异羟肟酸的环化反应。

  摘要：

  3-异恶唑醇最通常由β-酮酯和羟胺合成。该环化通常产生主要副产物，相应的5-异恶唑酮。我们已经发现，可以合成N，O-diBoc保护的β-酮异羟肟酸并将其环化成5-取代的3-异恶唑醇，而不会形成任何副产物。我们提出了一种新颖且通用的三步程序，其中将羧酸衍生物转化为酰基麦德鲁姆酸，当与N，O-双（叔丁氧基羰基）羟胺进行氨解后，会生成N，O-diBoc保护的β-酮异羟肟酸。然后，将这些异羟肟酸类似物用盐酸处理后，环化成相应的5-取代的3-异恶唑醇。

• 3-Oxoisoxazole-2(3H)-carboxamides and isoxazol-3-yl carbamates: Resistance-breaking acetylcholinesterase inhibitors targeting the malaria mosquito, Anopheles gambiae

  To identify potential selective and resistance-breaking mosquitocides against the African malaria vector Anopheles gambiae, we investigated the acetylcholinesterase (AChE) inhibitory and mosquitocidal properties of isoxazol-3-yl dimethylcarbamates (15), and the corresponding 3-oxoisoxazole-2(3H)-dimethylcarboxamide isomers (14). In both series, compounds were found with excellent contact toxicity to wild-type susceptible (G3) strain and multiply resistant (Akron) strain mosquitoes that carry the G119S resistance mutation of AChE. Compounds possessing good to excellent toxicity to Akron strain mosquitoes inhibit the G119S mutant of An. gambiae AChE (AgAChE) with k(i) values at least 10-to 600-fold higher than that of propoxur, a compound that does not kill Akron mosquitoes at the highest concentration tested. On average, inactivation of WT AgAChE by dimethylcarboxamides 14 was 10-20 fold faster than that of the corresponding isoxazol-3-yl dimethylcarbamates 15. X-ray crystallography of dimethylcarboxamide 14d provided insight into that reactivity, a finding that may explain the inhibitory power of structurally-related inhibitors of hormone-sensitive lipase. Finally, human/An. gambiae AChE inhibition selectivities of these compounds were low, suggesting the need for additional structural modification. (C) 2015 Elsevier Ltd. All rights reserved.
