Application

GTS-21 has been used:
  • as an α7 nicotinic acetylcholine receptors (nAChR) partial agonist to elucidate its anti-inflammatory effects in mouse macrophages
  • to test its protective effect on the renal injury induced by lipopolysaccharide (LPS)
  • to test its effect on microvascular inflammation in endotoxemia induced by LPS

Biochem/physiol Actions

GTS-2, a derivative of anisine is an immunomodulatory drug. It is used for treating pancreatitis and septicemia. GTS-2 inhibits the pro-inflammatory cytokines especially the interleukin-6 (IL6) and tumor necrosis factor (TNF) in sepsis and endotoxemia.
GTS-21 is a selective agonist at α-7 nicotinic receptors with anti-inflammatory and cognition enhancing activities. GTS-21 has also been investigated for the treatment of schizophrenia.

The vagus nerve can limit inflammation via the alpha7 nicotinic acetylcholine receptor (alpha7nAChR). Selective pharmacological stimulation of the alpha7nAChR may have therapeutic potential for the treatment of inflammatory conditions. We determined the anti-inflammatory potential of GTS-21, an alpha7nAChR-selective partial agonist

A large decrease in brain nicotinic receptor levels occurs in Alzheimer's disease, relative to muscarinic and other receptors. Neurons possessing high affinity nicotinic receptors seem particularly vulnerable. The low affinity nicotinic receptors which selectively bind alpha-bungarotoxin are not significantly affected.

Microglia, the innate immune cells of the brain, are commonly perceived as resident macrophages of the central nervous system (CNS). This definition, however, requires further specification, as under healthy homeostatic conditions, neither morphological nor functional properties of microglia mirror those

The pentameric acetylcholine-binding protein (AChBP) is a soluble surrogate of the ligand binding domain of nicotinic acetylcholine receptors. Agonists bind within a nest of aromatic side chains contributed by loops C and F on opposing faces of each subunit interface.

Nicotinic acetylcholine receptors (nAChRs) are drug targets for neuronal disorders and diseases. Partial agonists for nAChRs are currently being developed as drugs for the treatment of neurological diseases for their relative safety originated from reduced excessive stimulation. In the current
