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.

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.

L-DOPA (Levodopa) is an amino acid precursor of dopamine with antiparkinsonian properties. It is a prodrug converted to dopamine by DOPA decarboxylase and can cross the blood-brain barrier. In the brain, levodopa is decarboxylated to dopamine, stimulating dopaminergic receptors and compensating for depleted endogenous dopamine in Parkinson's disease. To ensure adequate concentrations reach the central nervous system, levodopa is administered with carbidopa, a decarboxylase inhibitor that does not cross the blood-brain barrier, reducing peripheral decarboxylation and increasing CNS dopamine delivery.

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.

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

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).

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

VX-984 (M9831) is an oral, selective DNA-PK inhibitor that can cross the blood-brain barrier. VX-984 inhibited the conjugation of non-homologous terminal NHEJ and acted on DSBs to break DNA double strand. VX-984 is commonly seen in glioblastoma (GBM) and non-small cell lung cancer (NSC-LC) studies.

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 precursor of MPP+, a dopamine neurotoxin with blood-brain barrier permeability. MPTP hydrochloride is toxic to dopaminergic neurons, which can lead to Parkinson's disease, and is widely used in the construction of animal models of Parkinson's disease.

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 a highly selective, brain-penetrant, and orally active CSF1R inhibitor.

Elamipretide (MTP-131) is a mitochondria-targeted antioxidant tetrapeptide (D-Arg-dimethylTyr-Lys-Phe-NH2) that reduces toxic reactive oxygen species (ROS) production and stabilizes cardiolipin, with blood-brain-barrier permeability. It is a potential therapeutic agent in the rare disease of Barnes syndrome.

Antihistamine-1 is an H1-antihistamine (Ki: 6.9 nM) with acceptable blood-brain barrier penetration and also an inhibitor of CYP2D6 and hERG channel (IC50s: 5.4 and 0.8 μM).
