Combination of Heme Oxygenase-1 Inhibition and Sigma Receptor Modulation for Anticancer Activity

open access: yesMolecules, 2021
Cancer is a multifactorial disease that may be tackled by targeting different signaling pathways. Heme oxygenase-1 (HO-1) and sigma receptors (σRs) are both overexpressed in different human cancers, including prostate and brain, contributing to the ...

STAT3, a hub protein of cellular signaling pathways, is triggered by β-hexaclorocyclohexane [PDF]

open access: yes, 2018
Background: Organochlorine pesticides (OCPs) are widely distributed in the environment and their toxicity is mostly associated with the molecular mechanisms of endocrine disruption.

A Structure- and Ligand-Based Virtual Screening of a Database of “Small” Marine Natural Products for the Identification of “Blue” Sigma-2 Receptor Ligands

open access: yesMarine Drugs, 2018
Sigma receptors are a fascinating receptor protein class whose ligands are actually under clinical evaluation for the modulation of opioid analgesia and their use as positron emission tomography radiotracers.

Ferrets exclusively synthesize Neu5Ac and express naturally humanized influenza A virus receptors [PDF]

open access: yes, 2014
Mammals express the sialic acids ​N-acetylneuraminic acid (​Neu5Ac) and ​N-glycolylneuraminic acid (​Neu5Gc) on cell surfaces, where they act as receptors for pathogens, including influenza A virus (IAV). ​Neu5Gc is synthesized from ​Neu5Ac by the enzyme

The Role of Sigma Receptors in Depression

open access: yesJournal of Pharmacological Sciences, 2005
Behavioral models used to test potential antidepressants have shown that ligands that bind to sigma receptors possess “antidepressant-like” properties.

Cardiac Sigma Receptors – An Update

open access: yesPhysiological Research, 2018
More than four decades passed since sigma receptors were first mentioned. Since then, existence of at least two receptor subtypes and their tissue distributions have been proposed. Nowadays, it is clear, that sigma receptors are unique ubiquitous proteins with pluripotent function, which can interact with so many different classes of proteins.

Pregnancy reduces brain sigma receptor function [PDF]

open access: yesBritish Journal of Pharmacology, 1999
Sigma (σ) receptors have recently been cloned, though their endogenous ligand(s) remain unidentified. However, some neuroactive steroids, such as progesterone, have a high affinity for these receptors. Some σ ligands, such as DTG, (+)‐pentazocine and DHEA, act as σ ‘agonists’ by potentiating the neuronal response to NMDA. Others, such as haloperidol,

Extracellular aspartic protease SAP2 of Candida albicans yeast cleaves human kininogens and releases proinflammatory peptides, Met-Lys-bradykinin and des-Arg(9)-Met-Lys-bradykinin [PDF]

open access: yes, 2012
Bradykinin-related peptides, universal mediators of inflammation collectively referred to as the kinins, are often produced in excessive amounts during microbial infections.

Adamantane-derived scaffolds targeting the sigma-2 receptor; an in vitro and in silico study

open access: yesSaudi Pharmaceutical Journal, 2021
Novel adamantane-based compounds were synthesized and assessed as potential sigma-2 receptor ligands. Molecular docking and 50 ns molecular dynamic simulation were carried out to determine the binding modes, mechanism of interaction, and stability of ...
