Selectivity profile comparison for certain γ-butyrolactone and oxazolidinone-based ligands on a sigma 2 receptor over sigma 1: a molecular docking approach
Sigma receptors (σ 1 R and σ 2 R) are pharmacologically characterized membrane-bound receptors that bind a wide range of chemical compounds. Alzheimer's disease, traumatic brain injury, schizophrenia, and neuropathic pain have all been associated with abnormal σ 2 activity. The σ 2 receptor has...

Summary: | Sigma receptors (σ
1
R and σ
2
R) are pharmacologically characterized membrane-bound receptors that bind a wide range of chemical compounds. Alzheimer's disease, traumatic brain injury, schizophrenia, and neuropathic pain have all been associated with abnormal σ
2
activity. The σ
2
receptor has recently been identified as a potential therapeutic target for inhibiting the formation of amyloid plaques. Numerous laboratories are now investigating the potential of σ
2
ligands. Small molecule discovery is the focus of current research, with the goal of using target-based action to treat a variety of illnesses and ailments. Functionalized γ-butyrolactone and oxazolidinone-based ligands, in particular, are pharmacologically important scaffolds in drug discovery research and have been thoroughly examined for σ
2
receptor efficacy. The purpose of this study was to evaluate the pharmacophoric features of different σ
2
receptor ligands using
in silico
techniques. This study used a library of 58 compounds having a γ-butyrolactone and oxazolidinone core. To investigate the binding characteristics of the ligands with the σ
2
receptor, a 3D homology model was developed. To understand the binding pattern of the γ-butyrolactone and oxazolidinone based ligands, molecular docking studies were performed on both σ
1
and σ
2
receptors. Furthermore, MM/GBSA binding energy calculations were used to confirm the binding of ligands on the σ
2
over σ
1
receptor. These
in silico
findings will aid in the discovery of selective σ
2
ligands with good pharmacophoric properties and potency in the future.
