  • In Vitro and In Silico Characterization of Kurarinone as a Dopamine D 1A Receptor Antagonist and ...

    Alterations in the expression and/or activity of brain G-protein-coupled receptors (GPCRs) such as dopamine D1R, D2LR, D3R, and D4R, vasopressin V1AR, and serotonin 5-HT1AR are noted in various neurodegenerative diseases (NDDs). Since studies have indicated that flavonoids can target brain GPCRs and provide neuroprotection via inhibition of monoamine oxidases (hMAOs), our study explored the functional role of kurarinone, an abundant lavandulated flavonoid in Sophora flavescens, on dopamine receptor subtypes, V1AR, 5-HT1AR, and hMAOs. Radioligand binding assays revealed considerable binding of kurarinone on D1R, D2LR, and D4R. Functional GPCR assays unfolded the compound's antagonist behavior on D1R (IC50 42.1 ± 0.35 μM) and agonist effect on D2LR and D4R (EC50 22.4 ± 3.46 and 71.3 ± 4.94 μM, respectively). Kurarinone was found to inhibit hMAO isoenzymes in a modest and nonspecific manner. Molecular docking displayed low binding energies during the intermolecular interactions of kurarinone with the key residues of the deep orthosteric binding pocket and the extracellular loops of D1R, D2LR, and D4R, validating substantial binding affinities to these prime targets. With appreciable D2LR and D4R agonism and D1R antagonism, kurarinone might be a potential compound that can alleviate clinical symptoms of Parkinson's disease and other NDDs. Read full article

  • High hedgehog signaling is transduced by a multikinase-dependent switch controlling the...

    October 2022 High hedgehog signaling is transduced by a multikinase-dependent switch controlling the apico-basal distribution of the GPCR smoothened "The oncogenic G-protein-coupled receptor (GPCR) Smoothened (SMO) is a key transducer of the hedgehog (HH) morphogen, which plays an essential role in the patterning of epithelial structures. Here, we examine how HH controls SMO subcellular localization and activity in a polarized epithelium using the Drosophila wing imaginal disc as a model. We provide evidence that HH promotes the stabilization of SMO by switching its fate after endocytosis toward recycling. This effect involves the sequential and additive action of protein kinase A, casein kinase I, and the Fused (FU) kinase. Moreover, in the presence of very high levels of HH, the second effect of FU leads to the local enrichment of SMO in the most basal domain of the cell membrane. Together, these results link the morphogenetic effects of HH to the apico-basal distribution of SMO and provide a novel mechanism for the regulation of a GPCR."
