Metformin hydrochloride (1,1-Dimethylbiguanide hydrochloride), a widely used anti-diabetic drug, exhibits potential anti-Y properties by inhibiting the proliferation of various Y cells, including colon and prostate.

Metformin (1,1-Dimethylbiguanide) is an AMPK activator with blood-brain barrier permeability. Metformin may improve glycemic control by increasing insulin sensitivity and decreasing intestinal glucose uptake, and is commonly used in type 2 diabetes research.

Oxybenzone is a UV filter commonly used in tanning and skin protection agents. It is a derivative of benzophenone and is used as an endocrine disrupting chemical that penetrates the placental and blood-brain barriers. It impairs autophagy, alters epigenetic status and disrupts vitamin X-like receptor signaling in apoptotic neuronal cells.

Pivagabine (CXB-722), a hydrophobic 4-aminobutyric acid derivative, exhibits neuromodulatory activity and successfully penetrates the blood-brain barrier in rats. It counteracts the impact of foot shock on GABAA receptor function and corticotropin-releasing factor (CRF) levels in the rat brain.

Physostigmine, a parasympathomimetic alkaloid, is a reversible cholinesterase inhibitor. It extracts from the Calabar bean.

Ebselen (CCG-39161) is a organoselenium compound with anti-inflammatory, anti-oxidant and cytoprotective activity. Ebselen acts as a glutathione peroxidase mimetic and is thereby able to prevent cellular damage induced by reactive oxygen species (ROS). In addition, this agent inhibits the activity of a variety of enzymes including nitric oxide synthase (NOS), 5-lipoxygenase, cyclooxygenase, protein kinase C (PKC), NADPH oxidase and gastric H+/K+-ATPase. Furthermore, ebselen may be neuroprotective due to its ability to neutralize free radicals upon NMDA receptor activation thus, reducing lipoperoxidation mediated by glutamate-induced excitotoxicity.

Seltorexant (JNJ-42847922) crosses the blood-brain barrier and quickly occupies OX2R binding sites in the rat brain. Seltorexant is a high-affinity and selective orexin-2 receptor antagonist (pKi: 8.0 and 8.1 for human and rat OX2R).

Tandutinib (CT53518) (MLN518, CT53518), an effective FLT3 antagonist (IC50: 0.22 μM), can also inhibit c-Kit and PDGFR, 15-20 fold higher potency for FLT3 versus CSF-1R and >100-fold selectivity for the same target versus FGFR, EGFR, and KDR.

MK-0752, a γ-secretase inhibitor, reduces Aβ40 production(IC50=5 nM).

Cefoselis Sulfate is a widely used beta-lactam antibiotic.

Carbetocin is an obstetric drug used to control postpartum hemorrhage and bleeding after giving birth.

L-DOPA (Levodopa) is an orally active metabolic precursor of the neurotransmitter dopamine. It can cross the blood-brain barrier and be converted into dopamine in the brain. L-DOPA exhibits anti-hyperalgesic effects and holds potential in Parkinson’s disease research, and it can also be used to induce Parkinson’s disease models.

Q-VD-OPh is an irreversible caspase inhibitor with an IC50 value of 48 nM against caspase-7 and between 25 and 400 nM against caspase-1, 3, 8, 9, 10, 12. Q-VD-OPh inhibits HIV infection and can cross the blood-brain barrier.

Rutin (Quercetin 3-O-rutinoside), a flavonoid, has a variety of biological activities including antiallergic, anti-inflammatory, antiproliferative, and anticarcinogenic properties.

Temozolomide (TMZ) is a DNA alkylating agent with blood-brain barrier permeability and oral activity. Temozolomide has antitumor activity and antiangiogenic activity, and also induces apoptosis and autophagy. Temozolomide is stable under acidic conditions and hydrolyzes under neutral or slightly alkaline conditions.

SC79 is an AKT agonist with specificity and blood-brain barrier permeability. SC79 specifically binds to the PH domain of AKT, activates cytoplasmic AKT, and inhibits AKT membrane translocation. SC79 has neuroprotective activity.

Firibastat (RB150) is a glutamyl aminopeptidase antagonist and an orally active brain penetrating prodrug of EC33. It is a first-in-class brain aminopeptidase A (APA) inhibitor with a Ki of 200 nM. Firibastat selectively and specifically inhibits conversion of brain angiotensin-II into angiotensin-III and decreases blood pressure in hypertensive rats[1][2].

MPTP hydrochloride is a dopamine neurotoxin and the precursor of MPP⁺. It can induce apoptosis and has the ability to cross the blood-brain barrier. MPTP hydrochloride is toxic to dopaminergic neurons and is commonly used for the construction of Parkinson's disease animal models.

Clozapine N-oxide is the major metabolite of Clozapine and is blood-brain barrier permeable. Clozapine N-oxide is an agonist of DREADDs and activates the DREADD receptors hM3Dq and hM4Di. Clozapine N-oxide is also a dopamine antagonist and selective muscarinic M4 receptor agonist.

C-176 (STING inhibitor 1) is a STING inhibitor with selectivity and blood-brain barrier permeability. C-176 inhibits STING-mediated IFNβ production and possesses anti-inflammatory activity.

PX-478 is a HIF-1α inhibitor with selectivity, oral activity, and blood-brain barrier permeability. PX-478 has antitumor activity and also protects pancreatic β-cell function in diabetes mellitus and is used in type 2 diabetes mellitus research.

Salvianolic acid A (Dan Phenolic Acid A) is a natural product and an inhibitor of matrix metalloproteinase 9 (MMP-9). Salvianolic acid A has antioxidant and anti-inflammatory activity and protects the blood-brain barrier.

TIC10 (ONC-201) inactivates Akt and ERK to induce TRAIL through Foxo3a, possesses superior drug properties: delivery across the blood-brain barrier, superior stability and improved pharmacokinetics. Phase 1/2.

PLX5622 is an orally active small-molecule CSF1R inhibitor that selectively depletes microglia in the brains of mice and rats. It is commonly used to establish models related to microglia-associated neuroinflammation, neurodegenerative diseases (such as Alzheimer's disease and Parkinson's disease), brain injury, and neuroimmune regulation.
