3D Brain Organoids: A Core Model for Deciphering the Brain

Intercellular Communication & Diseases Neurodegeneration Cellular Degeneration Proteostasis

Three-dimensional brain organoids are self-organizing neural tissues derived from human pluripotent stem cells that reproduce selected cellular and architectural features of developing brain regions. The modern field was established when cerebral organoids generated multiple interdependent regions, organized cortical progenitor zones, abundant outer radial glia, and neuronal subtypes, then modeled patient-specific microcephaly. Subsequent single-cell and physiological studies demonstrated broad cell diversity, prolonged maturation, dendritic spines, spontaneous network activity, and experimentally controlled responses. Brain organoids now occupy a central position between two-dimensional cultures and animal models because they preserve human genotype and multicellular organization while remaining accessible to imaging, genome editing, perturbation, and molecular profiling[1][2][3].

Organoid construction combines developmental patterning with intrinsic self-organization. Pluripotent cells form neuroepithelium, expand progenitor populations, generate neurons and glia, and arrange region-like domains according to culture cues and internal signaling. Single-cell analysis of more than 80,000 cells from 31 organoids identified cell classes related to cerebral cortex and retina; cultures maintained for more than nine months developed dendritic spines and active networks, and photosensitive cells enabled optical control. A directed dorsal-forebrain protocol later generated reproducible cortical diversity: analysis of 166,242 cells from 21 organoids found that 95% produced a highly similar cell-type repertoire and developmental trajectories. These results show both the self-organizing capacity of neural tissue and the importance of protocol-specific reproducibility[1][2][3].

Applications span neurodevelopmental disease, infection, toxicology, neurodegeneration, circuit physiology, and drug transport. Patient-derived microcephaly organoids showed premature neuronal differentiation, providing a phenotype that was difficult to reproduce in mice. Regional organoids can isolate cortex, retina, or choroid plexus biology, while fused models add interregional connectivity. Human choroid-plexus organoids formed a selective epithelial barrier and secreted cerebrospinal-fluid-like liquid in enclosed compartments. Their small-molecule selectivity resembled the in vivo barrier, and the system predicted central-nervous-system permeability of compounds. Combining transcriptomics, proteomics, imaging, electrophysiology, and genome editing can therefore connect a variant or exposure to cell composition, developmental trajectory, network function, and pharmacological response[1][2][4].

Organoids remain partial models. They usually represent fetal-like development and lack complete vascular perfusion, systemic immunity, sensory inputs, endocrine regulation, and organism-level behavior. Diffusion limits can create stress and selective cell loss in larger tissues, while uncontrolled regional composition can complicate comparisons. Directed protocols improve reproducibility but may narrow the biology being modeled; unguided protocols capture broader diversity but can increase batch variation. Future studies need reference-based cell annotation, standardized media and matrices, predefined quality criteria, adequate numbers of donors and clones, blinded analysis, and cross-laboratory replication. Vascular, immune, barrier, and assembloid extensions should be added only when they answer the biological question. Clinical translation requires evidence that an organoid endpoint predicts patient phenotype, drug exposure, efficacy, or toxicity beyond simpler assays. Studies should report organoid size, cell composition, oxygenation, electrophysiological maturity, and exclusion criteria before interpreting a disease phenotype. Parallel comparison with fetal tissue, primary patient material, and animal models can reveal which mechanisms are reproduced and which remain absent under the specific culture conditions tested in vitro[1][2][3][4].

HY-L028 CNS-Penetrant Compound Library
The blood-brain barrier (BBB) is the complex network of brain microvessels. It protects the brain from the external bloodstream environment and supplies the brain with the required nutrients for normal function. However, blood-brain barrier is also the obstacle to deliver beneficial drugs to treat CNS (central nervous system) diseases or brain tumors, as it has the least permeable capillaries in the entire body due to physical barriers (tight junctions). Therefore, it is crucial to discover drugs which can cross this barrier for the treatment of brain-based diseases, such as Alzheimer’s disease (AD), Parkinson’s disease (PD) and epilepsy. MCE offers a unique collection of 1,170 compounds with confirmed CNS-Penetrant property. It’s a useful tool for the discovery of drugs used for brain diseases, such as brain tumors, mental disorders, and neurodegenerative diseases.

HY-L063 Chemical Probe Library
Chemical probes are simply reagents with high potency, selectivity and cell-permeability which play important roles in both fundamental and applied biological research. In their most common application, chemical probes can establish the tractability of a specific target. They are used to interrogate the relationship between a target and its phenotype (biological tractability) as well as an ability to modulate that phenotype using a small molecule. Otherwise, chemical probes also have had a major impact in enabling and accelerating discoveries along the path to pioneer medicines. They have helped to improve the understanding of targets and pathways and have created opportunities for proprietary drug discovery efforts to an extent that would not have been possible otherwise. MCE provides a unique collection of 282 chemical probes with high potency (at least 100 nM potency), selectivity (at least 10-fold selectivity against any other target) and cell-permeability (at least 10 μM potency).

HY-L144 Mitochondrial Protection Compound Library
Normal mitochondrial function is critical for maintaining cellular homeostasis because mitochondria produce ATP and are the major intracellular source of free radicals. Cellular dysfunctions induced by intracellular or extracellular insults converge on mitochondria and induce a sudden increase in permeability on the inner mitochondrial membrane, the so-called mitochondrial membrane permeability transition (MMPT). MMPT is caused by the opening of pores in the inner mitochondrial membrane, matrix swelling, and outer membrane rupture. The MMPT is an endpoint to initiate cell death because the pore opening together with the release of mitochondrial cytochrome c activates the apoptotic pathway of caspases. The normal operation of mitochondrial function is important for maintaining normal cell death and treatment of mitochondrial diseases. MCE offers a unique collection of 1,112 compounds with identified and potential mitochondrial protective activity. MCE Mitochondrial Protection Compound Library is critical for drug discovery and development.

HY-L919 MCE CNS BBB Lead-like Library
With the aging population and increasing competitive pressures, neurodegenerative diseases of the central nervous system (CNS) have become a serious medical challenge in modern society, including Parkinson's disease, Alzheimer's disease, brain tumors, and multiple sclerosis. However, the success rate of CNS drug development remains remarkably low, primarily due to the blood-brain barrier (BBB). The blood-brain barrier (BBB) is a semipermeable barrier structure that surrounds the microvasculature of the CNS. In capillaries, the wedged endothelial cells are tightly packed and wedge-shaped, lining the interior of the vessels to form extensive tight junctions. Along with a range of receptors, transporters, efflux pumps, and other cellular components, this barrier regulates the entry and exit of molecules between the bloodstream and the brain. The intact BBB blocks the passage of most blood-borne substances into the brain, preventing nearly 100% of large-molecule drugs and over 98% of small-molecule drugs from entering. Compared to non-CNS drugs, physicochemical properties such as hydrogen bonds, lipophilicity, and molecular weight significantly influence a compound's ability to cross the BBB. Using artificial intelligence (AI) algorithms to predict BBB permeability, a predicted value greater than 0.75 indicates that the compound has strong potential to cross the BBB, providing a promising starting point for CNS drug discovery.

HY-L949 Spirocyclic Privileged Scaffold Lead-like Library
Spirocyclic compounds, with rigid 3D structures, high Fsp³ and strong conformational restriction, are highly privileged scaffolds in small-molecule drug screening. They overcome drawbacks of planar aromatic compounds such as poor solubility, high off-target risks and weak druggability. Their orthogonal bicyclic geometry fits well into protein pockets, improving target affinity, subtype selectivity, metabolic stability and membrane permeability, making them ideal for hit identification against kinases, GPCRs, PPIs and other targets. Spirocyclic scaffolds have been widely applied in oncology, antivirals, hypertension and CNS diseases, leading to many approved drugs and clinical candidates. SAR studies show that spiro-atom chirality, ring size and heteroatom substitution dominate bioactivity and selectivity, with the scaffold mainly serving as a conformational anchor. Azaspirocycles, spirooxindoles and spirosteranes target GPCRs, kinases, MDM2-p53 and PPIs. Approved drugs including irbesartan, spironolactone and rolapitant confirm their druggability, while revumenib and SAR405838 show promise against undruggable targets. The MCE Spirocyclic Druglike Library contains over 1,000 diverse, stereospecific molecules selected by Lipinski’s rules. It covers privileged cores such as azaspirocycles, oxaspirocycles and spirooxindoles. These molecules bear rich chiral centers and distinct 3D orientations, reducing non-specific binding and enhancing screening efficiency. Featuring novel scaffolds, the library offers a highly innovative starting point for drug discovery.

Oligomycin B exacerbates cytotoxic brain edema in rats with cerebral cortical contusion, increases intracranial pressure and brain water content, and aggravates mitochondrial damage in these rats. Oligomycin B is used in studies related to grape downy mildew, traumatic brain injury, wheat blast, and gray mold.

HY-P10233A SAAP 148 TFA
SAAP 148 TFA is a synthetic antimicrobial peptide (bacteria) that interacts with and disrupts the lipid bilayer of bacterial cytoplasmic membranes, thereby inducing changes in membrane permeability and bacterial death. SAAP 148 TFA kills drug-resistant, multidrug-resistant and persister bacterial strains, inhibits biofilm formation, eliminates established biofilms, and blocks bacterial colonization on implant surfaces. SAAP 148 TFA retains its activity after modification or immobilization, exhibits variable cytotoxicity in different human cell models, and shows reduced efficacy in protein-rich environments. SAAP 148 TFA can be used in infection-related research.

HY-112624B Dextran T70 (MW 70,000)
Dextran 70,000 is a high molecular weight polysaccharide formed by glucose linked by α-(1→6) glycosidic bonds. Dextran 70,000 can expand blood volume through colloidal osmotic pressure effect and inhibit cell adhesion and platelet aggregation through steric hindrance. At the same time, Dextran 70,000 can be used as a drug carrier to achieve targeted delivery through endocytosis. Dextran 70,000 is biologically inert and has low immunogenicity. It can be used for clinical blood volume expansion, anti-thrombotic research, and evaluation of vascular permeability in in vitro experiments. It can also be combined with fluorescent dyes for cell tracking and drug delivery research. The Dextran series of compounds are also natural polysaccharide drug carriers that can be connected to drugs through covalent bonding methods such as ester bonds, amide bonds or click chemistry, or self-assembled to form carriers such as nanoparticles and hydrogels. Dextran is biodegradable and biocompatible, and can achieve targeted delivery and controlled release of drugs. Dextran derivatives can prolong the half-life of drugs, increase local concentrations, and reduce the activity of immune clearance.
