Synthesis, structural activity-relationships, and biological evaluation of novel amide-based allosteric binding site antagonists in NR1A/NR2B N-methyl-d-aspartate receptors☆
摘要:
The synthesis and structure-activity relationship analysis of a novel class of amide-based biaryl NR2B-selective NMDA receptor antagonists are presented. Some of the studied compounds are potent, selective, non-competitive, and voltage-independent antagonists of NR2B-containing NMDA receptors. Like the founding member of this class of antagonists (ifenprodil), several interesting compounds of the series bind to the amino terminal domain of the NR2B subunit to inhibit function. Analogue potency is modulated by linker length, flexibility, and hydrogen bonding opportunities. However, unlike previously described classes of NR2B-selective NMDA antagonists that exhibit off-target activity at a variety of monoamine receptors, the compounds described herein show much diminished effects against the hERG channel and alpha(1)-adrenergic receptors. Selections of the compounds discussed have acceptable half-lives in vivo and are predicted to permeate the blood-brain barrier. These data together suggest that masking charged atoms on the linker region of NR2B-selective antagonists can decrease undesirable side effects while still maintaining on-target potency.

Processes for preparing an amine compound by catalytically hydrogenating a precursor nitrile compound. In a particular aspect, the present hydrogenation process occurs in a dipolar organic solvent in the presence of a palladium/carbon catalyst and a strong anhydrous protic acid. In a further aspect, the preferred embodiment relates to a process for deprotecting a compound to produce an amine compound. In yet a further aspect, the preferred embodiment relates to amine products produced by the present processes. These amine products may be used for a variety of purposes.

Discovery of a Potent and Highly Selective Dipeptidyl Peptidase IV and Carbonic Anhydrase Inhibitor as “Antidiabesity” Agents Based on Repurposing and Morphing of WB-4101
multidrug therapies and the relevance of dipeptidylpeptidaseIV (DPP IV) and carbonic anhydrases (CAs II and V) in T2DM and in the weight loss, we report a new class of multitarget ligands targeting the mentioned enzymes. We started from the known α1-AR inhibitor WB-4101, which was progressively modified through a tailored morphing strategy to optimize the potency of DPP IV and CAs while losing the adrenergic
2 型糖尿病 (T2DM) 患者的管理正在从以心脏为中心转变为以体重为中心,或者更好的是,以脂肪为中心的治疗。考虑到多药治疗的缺点以及二肽基肽酶 IV (DPP IV) 和碳酸酐酶 (CAs II 和 V) 在 T2DM 和体重减轻中的相关性,我们报告了一类新的多靶点配体靶向上述酶。我们从已知的 α 1 -AR 抑制剂 WB-4101 开始,通过定制的变形策略对其进行逐步修改,以优化 DPP IV 和 CA 的效力,同时失去肾上腺素能活性。获得的化合物12显示出令人满意的 DPP IV 抑制作用,具有良好的选择性 CA 特征(DPP IV IC 50:0.0490 μM;CA II Ki 0.2615 μM;CA VA K i 0.0941 μM;CA VB K i 0.0428 μM)。此外,其在 Caco-2 中的 DPP IV 抑制活性及其可接受的前 ADME/Tox 特征表明它是此类新型多靶点配体中的先导化合物。
