Bromoacetamido-PEG3-C2-Boc is a PEG-based PROTAC linker that is utilized in the synthesis of PROTACs. PROTACs themselves are small molecules composed of two different ligands connected by a linker; one ligand targets an E3 ubiquitin ligase, and the other targets a protein of interest. This mechanism allows PROTACs to leverage the intracellular ubiquitin-proteasome system for the selective degradation of target proteins.
- Application: used in the synthesis of PROTACs.
- Mechanism: facilitates the degradation of target proteins via the ubiquitin-proteasome system when incorporated into PROTACs.
- Research use: for research purposes only; not intended for sale to patients.
- Form: liquid (density: 1.252 g/cm3), colorless to light yellow.

PS-1145 is an IκB kinase (IKK) inhibitor with an IC50 of 88 nM, functioning to block TNFα-induced NF-κB activation by inhibiting IκBα phosphorylation in multiple myeloma (MM) cells. This inhibition is observed in a dose- and time-dependent manner. It also enhances the blockade of NF-κB activation when combined with Dexamethasone, and can inhibit the protective effect of IL-6 against Dexamethasone-induced apoptosis.
- Potent inhibitor of IKK activity.
- Blocks phosphorylation of IκBα.
- Inhibits TNFα-induced NF-κB activation.
- Reduces TNFα-induced intracellular adhesion molecule (ICAM)-1 expression.
- Demonstrates antiproliferative activity against certain human cells.
- Decreases serum levels of specific cytokines in vivo.
- Can block inflammation-induced weight gain during high-fat feeding.

AK-778-XXMU is a potent DNA binding inhibitor 2 (ID2) antagonist with a KD of 129 nM. It inhibits the ID2-KDR signaling axis, leading to the down-regulation of downstream angiogenic factors (VEGFA) and invasion-related proteins (MMP2/9), while up-regulating the tumor suppressor factor (PTEN). It can inhibit cell migration and invasion of glioma cell lines, induce apoptosis, and demonstrates significant cancer-suppressing potency. This compound is used for the study of glioma.
