POI (Protein of Interest) refers to the target protein, namely the disease-causing protein or key functional protein that undergoes degradation or functional modulation in molecular glue-mediated processes. The Molecular Glue POI Library consists of a series of fragments that can specifically bind to different types of POIs. As key components of molecular glues, these ligands form stable interactions with target proteins, laying the foundation for molecular glues to induce the interaction between POIs and E3 ubiquitin ligases. The covered POIs include various types such as cancer-associated GSPT1, androgen receptors, and abnormally aggregated proteins linked to neurodegenerative diseases.
This fragment library can be applied to the screening and optimization of targeted protein degraders. By screening ligands with high affinity and strong selectivity for specific POIs from the library, core structures can be identified to develop novel molecular glues. For instance, optimization of ligands targeting GSPT1 has yielded molecular glue degraders with enhanced degradation activity. Since many POIs are difficult to drug due to the lack of traditional small-molecule binding pockets, some ligands in the POI Ligand Library can modulate such POIs by inducing protein-protein interactions, thereby further expanding the scope of drug discovery for undruggable targets.
MCE has compiled a POI Fragment Library comprising thousands of POI fragments with molecular weights ranging from 150 to 400. This compound library can be widely applied in Molecular Glue research and development.

G protein-coupled receptors (GPCRs) are membrane proteins in humans and one of the most important targets in drug discovery. Approximately 35% of launched drugs are targeted GPCRs, making them a crucial class of targets in drug discovery.
The orthosteric site of a GPCR is its endogenous ligand’s (such as neurotransmitters or hormones) binding site. This site plays a central role in signal transduction. Small molecules binding to this site typically contain a protonatable amino group, enabling the formation of salt bridges or hydrogen bonds with acidic residues in the binding pocket. In contrast, the allosteric site does not directly initiate signaling but modulates the signal intensity of the GPCR by altering or stabilizing the conformation of the orthosteric site. Small molecules binding to the allosteric site often contain multiple aromatic rings to occupy hydrophobic pockets and achieve their functional effects.
MCE has collected over 7,106 reported bioactive molecules targeting GPCRs, covering Class A, B, and C GPCRs. These small molecules were subjected to AI representation to extract 2D and 3D features. Subsequently, we do screening by AI score based on similarity to identify molecules in diversity library highly similar to the reported bioactive molecules in both 2D and 3D, with a threshold greater than 0.7. Further screening based on cLogP was applied to select molecules with good lipophilicity, which facilitates the binding of small molecules to GPCRs. This diversity library can be widely applied to the discovery of compounds targeting GPCR proteins.

Synonyms: Dipalmitoyl-S-glyceryl-cysteine; S-[2,3-Bis(palmitoyloxy)propyl]cysteine
Research Areas:
Pam2Cys (Dipalmitoyl-S-glyceryl-cysteine; S-[2,3-Bis(palmitoyloxy)propyl]cysteine) is a TLR2 agonist and immunostimulant. Pam2Cys binds to TLR2 to activate dendritic cells and trigger the TLR2-dependent NF-κB signaling pathway. Pam2Cys also induces dendritic cell maturation by upregulating the expression of cell surface MHC II molecules. Pam2Cys activates innate immune signaling pathways, drives pro-inflammatory and antimicrobial responses, enhances the expression of macrophage activation markers, increases phagocytic activity, induces the release of IL-12 and pro-inflammatory cytokines, and polarizes macrophages into a pro-inflammatory, antimicrobial phenotype without interfering with IL-10-induced macrophage polarization. Pam2Cys also serves as the lipid moiety in synthetic lipopeptide vaccines and possesses self-adjuvant properties. Pam2Cys enhances the immunogenicity of conjugated peptide segments and induces cellular and humoral immune responses. However, it does not activate CD4 T cells in mouse splenocyte cultures when used alone. Pam2Cys activates pulmonary TLR2 signaling pathways, triggers innate immune responses, recruits neutrophils and macrophages, induces the secretion of various cytokines, alleviates symptoms and damages associated with influenza A virus infection in mice without impairing adaptive immunity. Pam2Cys can be used in studies related to tuberculosis and influenza A virus infection .

Hordenine-d6 (Ordenina-d6; Peyocactine-d6) is the deuterated-labeled Hordenine (HY-N0113). Hordenine (Ordenina; Peyocactine) is a multifunctional alkaloid with oral activity and blood-brain barrier penetration. Hordenine inhibits LPS-induced phosphorylation of p38, JNK, ERK1/2, p65, IκB, and AKT, prevents p65 nuclear translocation, and suppresses inflammatory cytokines and mediators. Hordenine promotes M2 macrophage polarization, restores blood-milk barrier integrity, alleviates oxidative stress by reducing ROS and MDA, and attenuates LPS-induced lung injury and pulmonary edema. Hordenine inhibits cAMP production, CREB phosphorylation, and MITF expression, thereby suppressing melanin synthesis in melanocytes and reconstructed epidermis. Hordenine activates the Wnt/β-catenin signaling pathway, promotes dermal papilla cell proliferation and hair shaft elongation, and accelerates hair regeneration. Hordenine activates DRD2, acts as a D3R partial agonist, α2A-AR full agonist, and 5-HT2A-R antagonist, and inhibits SERT and DAT. Hordenine inhibits α-synuclein accumulation and ameliorates motor deficits in Parkinson's disease models. Hordenine limits alcohol intake, reduces relapse drinking behavior, and modulates alcohol-induced conditioned place preference. Hordenine can be used for research on mastitis, skin pigmentation, acute lung injury, foodborne diseases, hair loss, Parkinson's disease, bacterial infections, and alcohol use disorder .

MCE-18 stands for Medicinal Chemistry Evolution 2018, which was first published in Journal of Medicinal Chemistry in 2019 for assessing molecular novelty and three-dimensional complexity. Developed based on Clarivate global pharmaceutical patent database, this descriptor was constructed via big-data analysis covering 28,161 patented lead compounds, 1,370 approved drugs and nearly 30,000 preclinical-to-phase III drug candidates from 23 top pharmaceutical companies worldwide between 1950 and 2018, followed by structural clustering and removal of redundant outdated scaffolds for data denoising. Its scoring system integrates five core structural features including aromatic ring (AR), aliphatic heterocycle (NAR), chiral center (CHIRAL), spiro atom (SPIRO), cyclic and acyclic sp³ carbon ratio together with a quadratic topological correction factor. Breaking the limitations of the single Fsp³ parameter, MCE-18 effectively distinguishes conventional flat aromatic scaffolds from modern 3D-enriched novel chemotypes, overcoming typical drawbacks of traditional compound libraries such as scaffold redundancy, low screening hit rates and poor compatibility with allosteric and PPI-related difficult targets.
This library contains over 37,000 structurally diverse compounds with favorable overall drug-likeness, suitable for high-throughput screening against canonical targets including kinases, GPCRs and proteases as well as challenging allosteric and PPI targets. Compounds comply with the developmental trend of modern novel drug discovery, supporting routine primary screening as well as early hit identification of allosteric modulators and PPI inhibitors, serving as an efficient screening resource for early-stage innovative drug discovery.

HS-CyBz is a Fluorescent probe for H₂S detection, enabling ratiometric optical/photoacoustic dual-modality in/ex vivo imaging. Its detection mechanism relies on nucleophilic substitution of its benzoic ester group by HS⁻, which releases an enolic meso-hydroxyltricarboheptamethine cyanine that then undergoes keto-enol tautomerization to form Cy-ketone; this tautomerization causes distinct shifts in absorption and emission spectra, producing a ratiometric response that reduces interferences from tissue scattering, autofluorescence, and probe concentration. In its initial state, HS-CyBz has an excitation wavelength of 595 nm, with emission bands centered at 805 nm (main) and 630 nm (minor); upon reaction with H₂S, the 805 nm emission band decreases while the 630 nm band drastically increases, and its absorption spectrum shows a sharp band at 775 nm and a shoulder band at 708 nm, which decrease upon H₂S reaction with a minor increase at 850 nm and an isosbestic point at 825 nm. For in vivo optical imaging, excitation at 560 nm is used with emission channels at 620 nm and 790 nm, while in vivo photoacoustic imaging uses excitation at 775 nm and 825 nm. The detection limit of HS-CyBz for H₂S is 0.5 μM, and it shows high selectivity, with only H₂S inducing a distinct enhancement of the emission ratio F₆₃₀/F₈₀₅ and PA ratio PA₈₂₅/PA₇₇₅, while other biochemical species including cations, anions, reactive oxygen species, biothiols, and carboxylesterase trigger only minor changes and do not interfere with H₂S sensing. Tail intravenous injection of HS-CyBz leads to accumulation in the liver of mice, and it can be used to verify endogenous H₂S upregulation triggered by S-adenosyl-L-methionine via ratiometric optical/photoacoustic imaging .
