CD24 Inhibitoren

Gängige CD24 Inhibitors sind unter underem Cycloheximide CAS 66-81-9, Actinomycin D CAS 50-76-0, Triptolide CAS 38748-32-2, MG-132 [Z-Leu- Leu-Leu-CHO] CAS 133407-82-6 und Rapamycin CAS 53123-88-9.

CD24 inhibitors include a variety of compounds that target different stages of the protein's cellular lifecycle, from gene transcription to protein degradation. Cycloheximide and Actinomycin D directly target the early stages of CD24 expression; Cycloheximide prevents CD24 translation by inhibiting eukaryotic protein synthesis, whereas Actinomycin D disrupts CD24 mRNA transcription. Triptolide acts at the transcriptional level too, inhibiting RNA polymerase II activity, which leads to a decrease in CD24 gene transcription. These actions highlight a critical aspect of cellular regulation, where the inhibition of fundamental processes like transcription and translation can specifically diminish the levels of target proteins such as CD24.

Furthermore, compounds like MG132 and Bortezomib, which are proteasome inhibitors, result in increased protein degradation and reduced CD24 protein levels due to cellular stress and proteotoxicity. Rapamycin, an mTOR inhibitor, indirectly impacts CD24 by altering protein synthesis pathways and autophagic processes. Curcumin and EGCG modulate various signaling pathways, with Curcumin known to suppress CD24 at the transcriptional level and EGCG observed to downregulate its expression. Additionally, Chloroquine, by modifying endosomal and lysosomal pH, affects CD24 protein degradation and turnover. Doxorubicin and 5-Fluorouracil, impacting DNA intercalation and nucleotide synthesis respectively, alter CD24 expression, while Mithramycin binds to DNA and affects transcription, decreasing CD24 expression.
