  Synthesis of the Four Isomers of 4-Aminopyrrolidine-2,4-dicarboxylate:  Identification of a Potent, Highly Selective, and Systemically-Active Agonist for Metabotropic Glutamate Receptors Negatively Coupled to Adenylate Cyclase

  摘要：

  The four isomers of 4-aminopyrrolidine-2,4-dicarboxylate (APDC) were prepared and evaluated for their effects at glutamate receptors in vitro. (2R,4R)-APDC (2a), an aza analog of the nonselective mGluR agonist (1S,3R)-1-aminocyclopentane-1,3-dicarboxylate ((1S,3R)-ACPD, 1), was found to possess relatively high affinity for metabotropic glutamate receptors (mGluRs) (ACPD-sensitive [H-3]glutamate binding IC50 = 6.49 +/- 1.21 mu M) with no effects on radioligand binding to NMDA, AMPA, or kainate receptors up to 100 mu M. None of the other APDC isomers showed significant mGluR binding affinity, indicating that this interaction is highly stereospecific. Both 1 and 2a were effective in decreasing forskolin-stimulated cAMP formation in the adult rat cerebral cortex (EC(50) = 8.17 +/- 2.21 mu M for 1; EC(50) = 14.51 +/- 5.54 mu M for 2a); however, while 1 was also effective in stimulating basal tritiated inositol monophosphate production in the neonatal rat cerebral cortex (EC(50) = 27.7 +/- 5.2 mu M), 2a (up to 100 mu M) was ineffective in stimulating phosphoinositide hydrolysis in this tissue preparation, further supporting our previous observations that 2a is a highly selective agonist for mGluRs negatively coupled to adenylate cyclase. Microelectrophoretic application of either 1 or 2a to intact rat spinal neurons produced an augmentation of AMPA-induced excitation (95 +/- 10% increase for 1, 52 +/- 6% increase for 2a). Intracerebral injection of 1 (400 nmol) produced characteristic limbic seizures in mice which are not mimicked by 2a (200-1600 nmol, ic). However, the limbic seizures induced by 1 were blocked by systemically administered 2a in a dose-dependent manner (EC(50) = 271 mg/kg, ip). It is concluded that (2R,4R)-APDC (2a) is a highly selective, systemically-active agonist of mGluRs negatively coupled to adenylate cyclase and that selective activation of these receptors in vivo can result in anticonvulsant effects.

  Combinatorial libraries of HIV and FIV protease inhibitors are characterized by α-keto amide or hydroxyethylamine core structures flanked by on one side by substituted pyrrolidines, piperidines, or azasugars and on the other side by phenylalanine, tyrosine, or substituted tyrosines. The libraries are synthesized via a one step coupling reaction. Highly efficacious drug candidates are identified by screening the libraries for binding and inhibitory activity against both HIV and FIV protease. Drug candidates displaying clinically useful activity against both HIV and FIV protease are identified as being potentially resistive against a loss of inhibitory activity due to development of resistant strains of HIV.

  HIV和FIV蛋白酶抑制剂的组合库以α-酮酰胺或羟乙基胺核心结构为特征，一侧为取代吡咯烷、哌啶或氮代糖，另一侧为苯丙氨酸、酪氨酸或取代酪氨酸。这些库是通过一步偶联反应合成的。通过筛选这些库，识别出对HIV和FIV蛋白酶的结合和抑制活性高效的药物候选化合物。对HIV和FIV蛋白酶都显示出临床有用活性的药物候选化合物被确定为潜在对抗由于HIV耐药株的发展而导致的抑制活性丧失。

  A nickel catalyzed synthesis of isomeric 3,3′-biproline esters is described. When those materials are doubly acylated with the acid chloride of pyrrole-2-carboxylic acid, they become susceptible to auto-oxidation in the presence of guanidine. Through proper staging of reaction conditions, it is possible to initiate two consecutive oxidative guanylations prior to in situ cycloisomerization to afford
