5-Hydroxy-2-(2-phenylethyl)chromone (5-HPEC): a novel non-nitrogenous ligand for 5-HT2B receptor.

ABSTRACT: Chromones are a class of natural products found in almost every known terrestrial plant with over 4000 naturally occurring derivatives having been isolated and structurally elucidated. Recently, 5-hydroxy-2-(2-phenylethyl)chromone (5-HPEC), isolated from Imperata cylindrical, showed neuroprotective activity against glutamate induced excitotoxicity in primary cultures of rat cortical cells. In comparison to other naturally occurring neuroprotective chromones, 5-HPEC contains fewer hydroxyl groups. Here we report our most recent characterization on this interesting natural product against a number of CNS receptors for the purpose to identify the potential molecular targets that may be related to its biological activity. Based on our studies, including radiobinding assays, calcium flux functional assays and molecular modeling studies, 5-HPEC may represent a type of novel nonnitrogenous ligands to the 5-HT2B receptor.

Stilbenes as ?-selective, non-nitrogenous opioid receptor antagonists.

Project description:The natural stilbene pawhuskin A has been shown to function as an opioid receptor antagonist, with preferential binding to the ? receptor. This finding encouraged assembly of a set of analogues to probe the importance of key structural features. Assays on these compounds determined that one (compound 29) shows potent opioid receptor binding activity and significantly improved selectivity for the ? receptor. These studies begin to illuminate the structural features of these non-nitrogenous opioid receptor antagonists that are required for activity.

Synthesis of novel analogs of cabergoline: improving cardiovascular safety by removing 5-HT2B receptor agonism.

Project description:The dopamine agonist cabergoline has been used to treat prolactinomas, Parkinson's disease, Cushing's disease and sexual dysfunction. However, its clinical use was severely curtailed when it was found that patients taking cabergoline had an increased risk of developing cardiac-valve regurgitation. This potentially life-threatening condition has been associated with drugs, such as cabergoline, that are 5-HT2B receptor agonists. We prepared analogs of cabergoline and have identified several that have limited or no agonism at the 5-HT2B receptor.

Characterization and Analysis of 2-(2-Phenylethyl)-chromone Derivatives from Agarwood (Aquilaria crassna) by Artificial Holing for Different Times.

Project description:A total of fifty-six chromones, including seven 5,6,7,8-tetrahydro-2-(2-phenylethyl)-chromones (THPECs), five 5,6-epoxy-2-(2-phenylethyl)chromones (EPECs), seven 5,6:7,8-diepoxy-2-(2-phenylethyl)chromones (DEPECs) and thirty-seven 2-(2-phenylethyl)chromones of the flidersia type (FTPECs), were characterized by HPLC/DAD/ESI/MS/MS in three agarwood samples (from Aquilaria crassna) induced by artificial holing with different holing times. The characteristic fragmentation behavior of DEPECs and EPECs, and the methods to distinguish these four types of chromones by MS analysis were described for the first time. In addition, it was found that the relative contents of DEPECs and EPECs were down-regulated, while the relative contents of THPECs and FTPECs were up-regulated for the samples from two, four and five years of the agarwood formation time. However, the relative contents of six most widespread and abundant FTPECs presented roughly upward based on the formation time. These results could be referenced to distinguish different agarwood samples collected from different formation time.

Serotonin receptor 5-HT2B mediates serotonin-induced mechanical hyperalgesia.

Project description:Serotonin [5-hydroxytryptamine (5-HT)] released from mast cells or platelets in peripheral tissues is one of the important inflammatory mediators in pain and hyperalgesia. The involvement of 5-HT in pain is complex because it could inhibit or facilitate nociceptive transmission, reflecting the presence of multiple 5-HT subtype receptors on peripheral and central nociceptors. The present study aimed to investigate the involvement of 5-HT(2B) in 5-HT-induced pain and whether the subtype exists in dorsal root ganglion (DRG) neurons. Injecting the 5-HT or 5-HT(2) agonist in hindpaws of mice induced significant hyperalgesia to mechanical stimuli, which was inhibited by the 5-HT(2B/2C) antagonist but not by 5-HT(1A), 5-HT(2A), or 5-HT(3A) antagonists. Therefore, 5-HT(2B) or 5-HT(2C) may be involved in 5-HT-induced mechanical hyperalgesia. The 5-HT(2B/2C) antagonist also blocked 5-HT-induced transient [Ca(2+)] signaling in DRG neurons. All subtypes of 5-HT receptors except 5-HT(2C) and 5-HT(6) are present in DRGs. In situ hybridization also demonstrated 5-HT(2B) mainly expressed in small- to medium-diameter DRG neurons that respond to pain. Likely, 5-HT(2B) mediates 5-HT-induced mechanical hyperalgesia in mice.

The chemical structures of these new compounds were elucidated by 1D and 2D NMR and MS data, single-crystal X-ray diffraction analysis, and electronic circular dichroism (ECD) calculations. The neuroprotective activities of these isolates were evaluated using an in vitro model of rat adrenal pheochromocytoma (PC12) cell injury induced by corticosterone. At concentrations from 5 to 40 µM, compounds 4 and 6, agarotetrol (9), and 6-hydroxy-2-(2-phenylethyl)chromone (17) showed significant protective activities against corticosterone-induced PC12 cell injury (P < 0.001).

Identification of 3-((1-(Benzyl(2-hydroxy-2-phenylethyl)amino)-1-oxo-3-phenylpropan-2-yl)carbamoyl)pyrazine-2-carboxylic Acid as a Potential Inhibitor of Non-Nucleosidase Reverse Transcriptase Inhibitors through InSilico Ligand- and Structure-Based Approaches.

Project description:Non-nucleosidase reverse transcriptase inhibitors (NNRTIs) are highly promising agents for use in highly effective antiretroviral therapy. We implemented a rational approach for the identification of promising NNRTIs based on the validated ligand- and structure-based approaches. In view of our state-of-the-art techniques in drug design and discovery utilizing multiple modeling approaches, we report here, for the first time, quantitative pharmacophore modeling (HypoGen), docking, and in-house database screening approaches in the identification of potential NNRTIs. The validated pharmacophore model with three hydrophobic groups, one aromatic ring group, and a hydrogen-bond acceptor explains the interactions at the active site by the inhibitors. The model was implemented in pharmacophore-based virtual screening (in-house and commercially available databases) and molecular docking for prioritizing the potential compounds as NNRTI. The identified leads are in good corroboration with binding affinities and interactions as compared to standard ligands. The model can be utilized for designing and identifying the potential leads in the area of NNRTIs.
