1400W is a slow, tight-binding, and highly selective inducible nitric-oxide synthase (iNOS) inhibitor, with a K_d value ≤ 7 nM. 1400W inhibits iNOS induction in microglial cells and reduces the generation of NO, thereby mitigating oxidative stress and neuronal cell apoptosis in the rat cerebral cortex, and improving spatial memory dysfunction caused by acute hypobaric hypoxia-reoxygenation [1] [2].
Artemisinin B is a drug which may improve spatial memory in dementia patients and alter the levels of inflammatory cytokines in the hippocampus and the cortex. Artemisinin B may inhibit neuroinflammation and exert neuroprotective effects on cognitive functions by modulating the TLR4-MyD88-NF-κB signaling pathway. Artemisinin B has shown potential in the treatment of neuroinflammatory diseases.

Guanfacine-13C,15N3is intended for us as an internal standard for the quantification of guanfacine by GC- or LC-MS. Guanfacine is an α2-adrenergic receptor (α2-AR) agonist with Kivalues of 93, 1,380, and 3,890 nM for α2A-, α2B-, and α2C-ARs, respectively, in a radioligand binding assay.1It has EC50values of 52, 288, and 602 nM for α2A-, α2B-, and α2C-ARs, respectively, for stimulated [35S]GTPγS binding. It also binds to imidazoline receptor 1 (Ki= 19 nM in a radioligand binding assay).2Guanfacine (0.3-5 mg kg) binds to adrenergic receptors in the central nervous system and lowers blood pressure in hypertensive rats in a dose-dependent manner.3It also improves spatial working memory deficits induced by hypobaric hypoxia in rats.4Formulations containing guanfacine are used in the treatment of high blood pressure and attention deficit hyperactivity disorder (ADHD). 1.Jasper, J.R., Lesnick, J.D., Chang, L.K., et al.Ligand efficacy and potency at recombinant α2 adrenergic receptors: Agonist-mediated [35S]GTPγS bindingBiochem.

Amyloid-β (1-42) (Aβ42) is a neurotoxic 42-amino acid protein fragment found in amyloid plaques in postmortem cerebral cortex from patients with Alzheimer's disease.1,2,3Aggregation of Aβ42 results in the formation of neurotoxic fibrils or globular oligomers.1Aβ42 accumulates in the brain of many transgenic mouse models of Alzheimer's disease and, in many models, the onset of amyloid deposition positively correlates with deficits in spatial learning and memory.4 1.Wolfe, M.S.Therapeutic strategies for Alzheimer's diseaseNat.
