Summary: Diprovocims are a new class of TLR agonists that act through the TLR1/TLR2 mechanism, exhibit structure-activity relationships, and have in vivo adjuvant activity. They have potent agonist activity towards human TLR1/TLR2 and can be functionalized without impacting this activity. Improvement in potency and efficacy in the murine system has also been achieved.

Summary: DCAF1 is a substrate receptor for two E3 ligases and has critical physiological role in protein degradation, making it a potential drug target for cancer and viral treatments. By screening a large compound library and conducting hit optimization, a compound called OICR-8268 was discovered as a tool compound for the development of DCAF1 ligands for cancer therapeutics. OICR-8268 showed strong target engagement and can be used for further investigation of DCAF1 functions and the development of DCAF1-based PROTACs.

Summary: The use of deep machine learning in protein structure prediction allows easy access to annotated conformations, which can compensate for missing experimental structures in structure-based drug discovery. However, the accuracy of these predicted conformations for screening chemical compounds that effectively interact with protein targets is still uncertain. This opinion article examines the benefits and limitations of using state-annotated conformations for ultra-large library screening, particularly for common drug targets like G-protein-coupled receptors.

Summary: A series of small-molecule degraders for alpha Syn aggregates were designed and synthesized using probe molecule sery308 as a warhead. Compound 2b showed the highest degradation efficiency with high selectivity. Mechanistic exploration revealed the involvement of both proteasomal and lysosomal pathways in this degradation process. The therapeutic effects of compound 2b were demonstrated in human neuroblastoma cells and Caenorhabditis elegans, expanding the substrate spectrum of PROTAC-based degraders.

Summary: RUVBL1 and RUVBL2 are highly conserved AAA ATPases that play a significant role in cancer progression. This study utilized docking-based virtual screening to identify compounds that inhibit the RUVBL1/2 complex. Seven compounds were found to have inhibitory activity in enzymatic and cellular assays. A series of pyrazolo[1,5-a]pyrimidine-3-carboxamide analogs were synthesized based on compound 15, which showed good potential for structural manipulation. Analysis of the structure-activity relationship revealed the importance of the benzyl group on R2 and the aromatic ring-substituted piperazinyl on R4 for inhibitory activity. Compound 18 exhibited the strongest inhibition and showed potential anticancer activity in multiple cell lines. Proteomic analysis identified cellular proteins dysregulated by compounds 16, 18, and 19. These findings suggest that compound 18 could serve as a starting point for structural modifications to improve potential therapeutic molecules.

Summary: Immunotherapy has revolutionized cancer treatment, with current therapies mostly based on antibodies. However, these therapies have limitations in terms of pharmacokinetics and immunogenicity. To overcome these limitations, researchers have focused on developing small molecule-based immunotherapy. This review provides an overview of the progress in small molecule-based immunomodulators for cancer therapy, including targeting PD-1/PD-L1, chemokine receptors, STING, TLR, etc. The importance of combining small molecule-based immunomodulators with therapeutic antibodies is also highlighted.

Summary: In this study, we identified Taspine as an antagonist of Toll-like receptor 2 (TLR2), which can effectively inhibit the activity of TLR2 and block the formation of the TLR2/MyD88 complex, thus reducing inflammation. We also synthesized a derivative of Taspine called SMU-Y6, which showed higher activity, better solubility, and improved drug-feasible properties. SMU-Y6 could reverse the polarization of M1 macrophages, reduce the production of inflammatory cytokines and infiltration of neutrophils, and alleviate local inflammation in mouse models.

Summary: A chemiluminescent probe activated by a thiol-chromene click nucleophilic reaction was designed and prepared in this study. The probe is initially chemiluminescent but turns off and releases extremely strong chemiluminescence in the presence of thiol. Real-time imaging of mice tumor sites showed significant chemiluminescence after the probe was injected, and the chemiluminescence of osteosarcoma tissues was also significantly stronger than that in adjacent tissues. The study concludes that this chemiluminescent probe has the potential to detect thiol, diagnose cancer (especially in its early stages), and aid in the development of related cancer drugs.

The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
