PLX-4545 is an orally active, selective molecular glue degrader targeting IKZF2. Through a molecular glue mechanism, PLX-4545 binds to CRBN, recruits IKZF2 to form a ternary complex, and promotes its ubiquitination and proteasomal degradation. This further converts inhibitory regulatory T cells (Treg) into effector-like T cells, enhances CD8 + T cell responses, and modulates the Teff:Treg balance. PLX-4545 also increases the production of the inflammatory cytokine IL-2 and reduces the suppressive activity of Treg. PLX-4545 can be used in cancer immunotherapy research, and exhibits a synergistic effect when combined with immune checkpoint inhibitors such as anti-PD1 .

Gastric Cancer (GC) is one of the most common malignant tumors in the world, ranking fourth in mortality rate globally. Because the early symptoms of stomach neoplasm are usually not obvious, are diagnosed with gastric cancer at terminal stage, and the relative survival rate within 5 years is very low. With the further understanding of the molecular characteristics of stomach neoplasm, many therapeutic targets for gastric cancer have been identified, and molecular targeted therapies such as CTLA-4, HER2 and immune checkpoint inhibitors have made rapid progress. Although survival rates for patients with gastric neoplasm have improved over the past few decades, the prognosis is still worrying. Therefore, there is an urgent need for new drugs to treat gastric cancer.
MCE designs a unique collection of 1,203 small molecules with definite or potential anti-gastric cancer activity, which is an important tool for studying the pathological mechanism of stomach neoplasm and developing drugs for stomach neoplasm.

P18IN011 is an inhibitor that specifically targets the interaction between p18(INK4C) and CDK6, with an IC50 of 3.61 μM against mouse p18INK4C. P18IN011 relieves p18-mediated CDK6 inhibition, thereby effectively regulating the G1 phase cell cycle checkpoint. P18IN011 significantly enhances the proliferation, self-renewal and bone marrow reconstitution abilities of hematopoietic stem cells, and increases the frequency of primitive hematopoietic cells to promote cobblestone area formation. Acting specifically on p18-expressing hematopoietic cells via CDK4/6, P18IN011 not only supports the ex vivo expansion of human umbilical cord blood hematopoietic stem cells, but also maintains their long-term reconstitution capacity during in vitro culture to enable multi-lineage transplantation .

PD-1/PD-L1 are key immune checkpoint targets that suppress T-cell-mediated anti-tumor immunity, representing a major focus in cancer immunotherapy. While antibody drugs dominate the clinic, they are limited by administration challenges and immune-related side effects. Small-molecule PD-1/PD-L1 inhibitors, with oral availability, good tissue penetration and low cost, have emerged as a promising next-generation strategy.
A PD-1/PD-L1 lead-like library was built via a five-step virtual screening process. After collecting 8,947 inhibitors from BindingDB and PubChem and filtering by activity and duplicates, AI similarity screening was performed using GeminiMol. Key pharmacophores were extracted from the PPI interface of co-crystal structures, and molecular was screened via a pharmacophore model, effectively enhancing target activity.
Containing 10,000 structurally diverse and drug-like molecules well-matched to the PD-L1 pocket, the library supports virtual docking, high-throughput screening and hit discovery, enabling efficient and rapid development of small-molecule immunotherapies.
