PROTAC IDO1 Degrader-1 is the first potent IDO1 (indoleamine 2,3-dioxygenase 1) degrader that hijacks IDO1 to CRBN E3 ligase to introduce IDO1 into UPS and eventually achieve ubiquitination and degradation (DC50=2.84 μM). PROTAC IDO1 Degrader-1 moderately improves the tumor-killing activity of H ER2 CAR-T cells[1]. PROTAC IDO1 Degrader-1 (compound 2c) (10 μM; 24 hours) notably decreases IDO1 level induced by IFN-γ[1].PROTAC IDO1 Degrader-1 and IFN-γ (5 ng mL) are incubated with HeLa cells for 24 h, and a significant dose-dependent degradation is observed. PROTAC IDO1 Degrader-1 combined with chimeric antigen receptor-modified T (CAR-T) cells can improve the tumor-killing activity of HER-2 CAR-T cells[1].PROTAC IDO1 Degrader-1 induces significant and persistent degradation of IDO1 with maximum degradation (dmax) of 93% in HeLa cells[1].

The chimeric peptide M35 [galanin (1-13)-bradykinin(2-9) amide] is a high-affinity galanin receptor ligand acting as a galanin receptor antagonist in the rat spinal cord, rat hippocampus and isolated mouse pancreatic islets. The radiolabelled M35 and perf
PROTAC BRD4 degrader for PAC-1 (compound 5) is a chimeric BET degrader GNE-987 conjugated with a disulfide-containing linker[1]. This PROTAC-linker conjugate specifically targets and degrades BRD4, enabling selective proteolysis of PAC-1.
Selective ultrapotent PSEM (uPSEM) agonist for α7L131G,Q139L,Y217F-GlyR (PSAM4-GlyR) and PSAM4-5-HT3 chimeric ion channel agonist (EC50 values are 0.3 and 0.5 nM, respectively). Suppresses firing of layer 2 3 cortical neurons expressing PSAM4-GlyR in brain slices. Increases contralateral rotation in mice expressing PSAM4-GlyR unilaterally in the substantia nigra reticulata (LED 0.1 mg kg).
