  Positive allosteric modulators (PAMs) of nicotinic acetylcholine receptors (nAChR) are important therapeutic candidates as well as valuable research tools. We identified a novel type II PAM, (R)-7-bromo-N-(piperidin-3-yl)benzo[b]thiophene-2-carboxamide (Br-PBTC), which both increases activation and reactivates desensitized nAChRs. This compound increases acetylcholine-evoked responses of α2* and α4* nAChRs, but is without effect on α3* or α6* nAChRs ("*" indicates presence of other nAChR subunits). Br-BPTC binds to the C-terminal extracellular sequences of a4 subunits, which is also a PAM site for steroid hormone estrogens such as 17-β estradiol. Br-PBTC is much more potent than estrogens. Like 17-P-estradiol, the non-steroid Br-PBTC only requires one α4 subunit to potentiate nAChR function, and its potentiation is stronger with more a4 subunits. This feature enables Br-BPTC to potentiate activation of (α4β2)(α6β2)β3 but not (α6β2)2β3 nAChRs. Various bioactive analogs of Br-PBTC are provided.

  正向变构调节剂（PAMs）对尼古丁乙酰胆碱受体（nAChR）是重要的治疗候选药物，同时也是有价值的研究工具。我们发现了一种新型II型PAM，(R)-7-溴-N-(哌啶-3-基)苯并[b]噻吩-2-甲酰胺（Br-PBTC），它既增加了激活，又重新激活了脱敏的nAChRs。这种化合物增加了α2*和α4* nAChRs对乙酰胆碱的响应，但对α3*或α6* nAChRs没有影响（"*"表示存在其他nAChR亚基）。Br-BPTC结合到α4亚基的C端外胞外序列，这也是类固醇激素雌激素如17-β雌二醇的PAM位点。Br-PBTC比雌激素更有效。与17-β雌二醇一样，非类固醇Br-PBTC只需要一个α4亚基来增强nAChR功能，并且随着更多的α4亚基，其增强作用更强。这个特性使Br-BPTC能够增强(α4β2)(α6β2)β3而不是(α6β2)2β3 nAChRs的激活。提供了各种生物活性类似物的Br-PBTC。

• Drug Design, in Vitro Pharmacology, and Structure−Activity Relationships of 3-Acylamino-2-aminopropionic Acid Derivatives, a Novel Class of Partial Agonists at the Glycine Site on the <i>N</i>-Methyl-<scp>d</scp>-aspartate (NMDA) Receptor Complex

  Retaining agonistic activity at the glycine coagonist site of the NMDA receptor in molecules derived from glycine or D-serine has proven to be difficult because in the vicinity of the alpha-amino acid group little substitution is tolerated. We have solved this problem by replacing the hydroxy group of D-serine with an amido group, thus keeping the hydrogen donor function and allowing For further substitution and exploration of the adjacent space. Heterocyclic substitutions resulted in a series of 3-acylamino-2-aminopropionic acid derivatives, with high affinities in a binding assay for the glycine site. In a functional assay assessing the activation of the glycine site, these compounds displayed a wide range of intrinsic efficacies, from antagonism to a high degree of partial agonism. Structure-activity relationships reveal that lipophilic substituents, presumably filling an additional hydrophobic pocket, are accepted by the glycine site, provided that they are separated from the alpha-amino acid group by a short linker.
