Melatonin is a neurotransmitter produced by the pineal gland that is involved in the regulation of sleep-wake cycles. It can be used to treat several conditions like shift work disorders, insomnia, jet lag, and alterations of the circadian rhythm. Some authors also proposed the use of melatonin against cognitive disorders. In an interesting research conducted on zebrafish, it was found that memory formation occurs better during daytime compared to nighttime, suggesting a role of melatonin in this process. When melatonin was administered during the daytime it caused reduced memory formation. On the contrary, removing the pineal gland or treating the fish with a melatonin antagonist significantly improves nighttime memory formation.

S26131 is an advanced glycation end product (AGE) inhibitor, which is a synthetic compound designed for laboratory research purposes. It is derived from chemical synthesis processes, offering a robust tool for investigating the biochemical pathways associated with glycation. Its mechanism of action involves the inhibition of AGE formation, which is a post-translational modification resulting from the non-enzymatic reaction between sugars and proteins or lipids. This biochemical modulation is vital for studying the implications of glycation in various physiological and pathological contexts.

ÎŽ opioid receptor agonist; anti-nociceptive; anti-depressant

Positive allosteric modulator of the metabotropic glutamate receptor mGluR5 with EC50 in submicromolar range. The compound is able to increase mGluR5 function in vitro and in vivo. A study showed that ADX-47273 enhanced fear extinction learning as well as improved reversal learning in experimental animals.

3-Hydroxy-5-{[(naphthalen-2-yl)carbamoyl]amino}benzoic acid is a synthetic compound characterized by its complex molecular structure incorporating naphthalene and benzoic acid moieties. As a derivative of benzoic acid, it is typically synthesized through a series of chemical reactions designed to introduce the 3-hydroxy and carbamoyl functional groups, creating a compound with potentially unique bioactive properties.

γ-secretase inhibitor; reduces amyloid-β in brainÂ

Cetirizine is a selective histamine-1 antagonist drug used for the treatment of allergies. One of the common uses is for a condition called allergic rhinitis. As Cetirizine is an antihistamine, its main mode of action is by selectively inhibiting H1 receptors. In vivo and ex vivo animal models have shown insignificant anticholinergic and antiserotonergic effects.

Crizotinib is a drug that belongs to the group of tyrosine kinase inhibitors. It is used in the treatment of cancers, including non-small cell lung cancer, small cell lung cancer, and other types of solid tumours. Crizotinib inhibits the activity of the tyrosine kinase ALK or anaplastic lymphoma kinase, which is involved in many signalling pathways and biological processes. The inhibition of this enzyme leads to decreased energy metabolism, reduced mitochondrial membrane potential and increased susceptibility to apoptosis.

Pan-class I phosphatidylinositide 3-kinase (PI3K) inhibitor (IC50 = 3, 33, 3 and 75 nM at catalytic subunits p110α, p110β, p110δ and p110γ respectively). Inhibits proliferation in several cancer cell lines, such as glioblastoma, breast and prostate cancer cells. Has synergistic anti-cancer effect in combination with MEK/ERK kinase inhibitor GDC-0973 (cobimetinib).

Inhibitor of human neutrophil elastase

Bosentan is a dual endothelin receptor antagonist that is used to treat hypertension. This drug works by blocking the action of endothelin molecules which prevents the narrowing of blood vessels and decreases blood pressure.

Regaloside D is a natural product derived from plant sources, specifically isolated from certain species known for their bioactive properties. It functions as a glycoside, a compound in which a sugar is bound to a non-carbohydrate moiety, potentially influencing a variety of cellular processes through its interaction with specific molecular targets.

Inhibitor of leucine-rich repeat kinase LRRK2Â

Inhibitor of p38 kinase

A potent inhibitor of phosphodiesterase type 9 (PDE9) tested in human and murine in vitro assays (IC50 values: 55 nM and 100 nM respectively). BAY 73-6691 induces long-term potentiation and improves memory in rodents. Has therapeutic potential for Alzheimer’s disease.

Short acting monoamine oxidase inhibitor

AZD9567 is a selective glucocorticoid receptor modulator (SGRM), which is a synthetic pharmaceutical compound. Its source is rooted in medicinal chemistry efforts to design ligands that selectively interact with glucocorticoid receptors. The mode of action of AZD9567 involves binding to glucocorticoid receptors with high specificity, modulating their activity to trigger anti-inflammatory and immunomodulatory responses while minimizing common side effects associated with traditional glucocorticoids.

Inhibitor of glycogen synthase 3 (GSK-3) and cyclin-dependent kinases CDK1, CDK2 and CDK5. Kenpaullone can substitute transcription factor Klf4 in reprogramming of fibroblast to induced pluripotent stem cells when using the method of ectopic expression of transcriptional factors. In an in vitro model for Alzheimer’s disease, kenpaullone decreased production of amyloid beta peptides Aβ40 and Aβ42.
