Thioacetanilide N-Phenylthioacetamide	Biochemical Assay Reagents	Metabolic Disease
Thioacetanilide (N-Phenylthioacetamide) is a sulfur-containing thioamide derivative of acetanilide. Thioacetanilide displays a solvent‑dependent Z/E isomeric distribution, preferring the E conformation in polar hydrogen‑bonding solvents and the Z conformation in halogenated solvents. Thioacetanilide serves as a substrate for metabolic desulfurization and aromatic hydroxylation. Thioacetanilide is mainly metabolized via desulfurization and 4‑hydroxylation of the aromatic ring in Rattus norvegicus, and the released sulfur integrates into the total body sulfur pool. Thioacetanilide is well absorbed in rats, and more than 90% of the dose is excreted in urine as conjugated metabolites after oral administration .

Keap1-Nrf2-IN-13	Keap1-Nrf2	Inflammation/Immunology Cancer
Keap1-Nrf2-IN-13 is a Keap1-Nrf2 protein–protein interaction (PPI) inhibitor with an IC₅₀ value of 0.15 μM. Keap1-Nrf2-IN-13 has strong binding affinities to the Keap1 protein by forming **hydrogen bond** with the key polar residues (Asn414, Arg415, Arg483, Gln530). Keap1-Nrf2-IN-13 can be used in the research of oxidative stress-related and inflammatory diseases, including pulmonary fibrosis, chronic obstructive pulmonary disorder (COPD) and cancers .

RIPK1-IN-40	RIP kinase Necroptosis	Cancer
RIPK1-IN-40 (Compound 51) is a RIPK1 inhibitor and anti-necroptotic agent (with an EC₅₀ of 0.07 μM against necroptosis). RIPK1-IN-40 binds to the kinase domain of RIPK1, forms hydrogen bond interactions with Met95, and establishes additional polar contacts with Asp156 to stabilize binding, thereby inhibiting necroptosis. RIPK1-IN-40 can be used for the research of colorectal cancer .

Molecular Glue Virtual Library	11412 compounds
Molecular Glue Virtual Library is constructed using generative AI technology, integrating the structural features, activity data of known molecular glues, and interaction information of ternary complexes (target protein-E3-molecular glue). Endowed with structural novelty, drug-likeness, diversity and synthesizability, it is applicable to molecular glue-based AI drug screening and large-scale virtual screening. MCE builds this library based on high-quality molecular building blocks by virtue of robust computing power, coupled with rigorous reaction rules and optimized compound generation strategies. To ensure library quality, molecules with high synthetic difficulty, poor drug-likeness, PAINS and other undesirable molecules are excluded first. Subsequently, scaffold-based compound analysis is performed to screen drug-like diverse molecules for synthesizability evaluation; those with excessively high synthetic difficulty are removed, ultimately forming a large-scale molecular glue virtual library with structural diversity, synthesizability and drug-likeness. Compounds in the library can be synthesized in only 1-2 chemical reaction steps. With MCE’s experienced chemical synthesis team, custom synthesis of different scales from milligram to kilogram can be easily achieved to meet diverse customer needs.

Allosteric Modulator Fragment Library	1802 compounds
In contrast to the high conservation of conventional orthosteric sites, allosteric sites possess structural characteristics of low conservation, high hydrophobicity, weak polarity, confined spatial geometry, and dynamic cryptic properties. There is a significant difference between their core structures and orthosteric pockets — allosteric pockets are mostly dynamic grooves formed by protein conformational changes, subunit interface clefts, or shallow depressions, rather than the rigid "keyhole" structure of orthosteric sites. With looser spatial constraints, allosteric sites have the advantages of high selectivity and low off-target risk, and have become an important direction in new drug discovery. Based on the dynamic, hydrophobic, and narrow-long spatial characteristics of allosteric pockets, MCE has performed targeted modification and screening of fragments. The screening criteria strictly conform to the requirements of allosteric binding: molecular weight is controlled at 120–280 Da (to meet the core needs of small molecules in fragment libraries and high derivatization), hydrogen bond donors (HBD ≤ 2), hydrogen bond acceptors (HBA ≤ 3), polar surface area (PSA = 30–80 Å²), rotatable bonds (≤ 2), moderate hydrophobicity (cLogP = 1–3.5), no strongly ionizable groups, and both appropriate rigidity and conformational flexibility to adapt to the dynamic changes of the pocket. Meanwhile, combined with the results of principal moment of inertia (PMI) analysis, fragments with high 3D diversity were obtained. Such fragments have good shape complementarity with allosteric pockets, ensuring that the fragments can smoothly enter the allosteric pockets and form stable binding, while providing room for subsequent optimization and derivation. This library contains 1,800 structurally diverse fragment molecules with excellent drug-like properties, suitable for allosteric drug development and the design and optimization of allosteric sites. It combines the
