Dual AChE-MAO B-IN-5, an indanone derivative, serves as an effective dual inhibitor for AChE and MAO-B, displaying IC50 values of 0.0224 μM for AChE, 0.0412 μM for MAO-B, and 0.1116 μM for MAO-A. Additionally, it exhibits antioxidant properties and inhibits β-amyloid plaque aggregation, making it suitable for Alzheimer’s disease (AD) research.

PDE5-IN-10 (compound 4b), a potent phosphodiesterase type 5 (PDE5) inhibitor, exhibits an effective half-maximal inhibitory concentration (IC50) of 20 nM, enhanced in vitro microsomal stability (t 1/2 = 44.6 min), and excellent efficacy in restoring long-term potentiation, making it suitable for Alzheimer’s disease (AD) research [1].

Ensaculin is a NMDA antagonist and a 5HT1A agonist potentially for the treatment of Alzheimer's disease (AD). Ensaculin showed memory-enhancing effects in paradigms of passive and conditioned avoidance in both normal and artificially amnesic rodents. It e

Blonanserin D5 is a deuterium-labeled Blonanserin. Blonanserin (AD-5423) is a dopamine D2/5-HT2 receptor antagonist with an atypical antipsychotic effect.

Blonanserin (AD-5423) is an atypical antipsychotic approved in Japan in January, 2008. Relative to many other antipsychotics, blonanserin has an improved tolerability profile, lacking side effects such as extrapyramidal symptoms, excessive sedation, or hypotension.

Blonanserin D8 is a deuterium-labeled Blonanserin. Blonanserin (AD-5423) is a dopamine D2/5-HT2 receptor antagonist with an atypical antipsychotic effect.

Chalcones A-N-5, a trihydroxy chalcone derivative, exhibits no cytotoxicity at concentrations below 100 µM (with IC 50 > 1 mM) and notably enhances cell proliferation. It is particularly effective in encouraging neuronal cell growth within damaged brain tissue and demonstrates an ability to inhibit ferroptosis triggered by RSL or erastin, while also reducing lipid peroxidation levels associated with Aβ1-42 protein aggregation. Given these properties, Chalcones A-N-5 represents a promising molecular framework for further development as a lead compound in in vivo studies aimed at researching Alzheimer's Disease (AD) [1].

Zonisamide-13C2,15N is intended for use as an internal standard for the quantification of zonisamide by GC- or LC-MS. Zonisamide is an antiepileptic agent.1 It selectively inhibits the repeated firing of sodium channels (IC50 = 2 μg/ml) in mouse embryo spinal cord neurons and inhibits spontaneous channel firing when used at concentrations greater than 10 μg/ml.2 In rat cerebral cortex neurons, zonisamide (1-1,000 μM) inhibits T-type calcium channels with a maximum reduction of 60% of the calcium current.3 Zonisamide inhibits H. pylori recombinant carbonic anhydrase (CA) and the human CA isoforms I, II, and V with Ki values of 218, 56, 35, and 21 nM, respectively.4,5 In mice, it has anticonvulsant activity against maximal electroshock seizure (MES) and pentylenetetrazole-induced maximal, but not minimal, seizures (ED50s = 19.6, 9.3, and >500 mg/kg, respectively). Zonisamide (40 mg/kg, p.o.) prevents MPTP-induced decreases in the levels of dopamine , but not homovanillic acid or dihydroxyphenyl acetic acid , and increases MPTP-induced decreases in the dopamine turnover rate in mouse striatum in a model of Parkinson's disease.6 Formulations containing zonisamide have been used in the treatment of partial seizures in adults with epilepsy. |1.
