Enhancing a CH−π Interaction to Increase the Affinity for 5-HT1A Receptors
摘要:
An electrostatic interaction related to a favorable position of the distal phenyl ring and a phenylalanine residue in the binding pocket would explain the higher 5-HT1A affinity of a 4-phenyl-1,2,3,6-tetrahydropyridine (THP) analogue compared to the corresponding 4-phenylpiperazine analogue. To explore a possible reinforcement of this interaction to increase the affinity for 5-HT1A receptors, different 4-substituted-phenyl analogues were synthesized and tested. The most important increase of affinity is obtained with two electron-donating methyl groups in positions 3 and 5.

compound’s bindingkinetics have been largely ignored, the importance of which is now being increasingly recognized. In the present study, we performed an extensive structure–kinetics relationship (SKR) study in addition to a traditional SAR analysis at the adenosine A2A receptor (A2AR). The ensemble of 24 A2AR compounds, all triazolotriazine derivatives resembling the prototypic antagonist ZM241385 (4‐(

strategies for its synthesis to date have required multistep methods and have been very limited, such as the use of SNAr‐type reactions. Herein, we describe a synthetic methodology employing benzynes, 1,4‐diazabicyclo(2.2.2)octane (DABCO), and nitrogen nucleophiles to access these privileged organic compounds. The established protocol proved to be a transition‐metal‐free, mild reaction that proceeded via
2-(4-苯基哌嗪-1-基)乙-1-胺支架是结构上重要的基序,在药物和药物化学中经常出现。尽管该部分具有重要意义,但迄今为止,其合成的一般策略仍需要多步方法,并且非常局限,例如使用S N Ar型反应。在这里,我们描述了一种合成方法,该方法使用苯炔,1,4-二氮杂双环(2.2.2)辛烷(DABCO)和氮亲核试剂来访问这些特权有机化合物。业已证明的既定规程是无过渡金属的轻度反应,其反应是通过由苯甲酸和DABCO形成的季铵盐进行的。
Small-Molecule Inhibition of the UNC119-Cargo Interaction
chaperones UNC119A/B regulate the cellular distribution and signaling of N-myristoylated proteins. Selective small-molecule modulators of the UNC119-cargointeraction would be invaluable tools, but have not been reported yet. We herein report the development of the first UNC119-cargointeraction inhibitor, squarunkin A. Squarunkin A selectively inhibits the binding of a myristoylated peptide representing

A series of N-(4-phenyl- and 4-pyridyl-1-piperazinylethyl)- and N-(4-phenyl-1-piperidinylethyl)-phthalmides were synthesized and tested for antipsychotic activity. All compounds suppressed the spontaneous motor activity and the apomorphine-induced climbing in mice and pergolide-induced locomotor activity in rats, demonstrating psychotropic properties equal to the corresponding properties of sulpiride
