Sunitinib D10 is a deuterium labeled Sunitinib. Sunitinib is a inhibitor of multi-targeted receptor tyrosine kinase(IC50s of 80 nM and 2 nM for VEGFR2 and PDGFRβ, respectively).
SB02024 is a VPS34 inhibitor. SB02024 activates cGAS-STING signaling and sensitizes tumors to STING agonist. SB02024 blocked autophagy in vitro and reduced xenograft growth of two breast cancer cell lines, MDA-MB-231 and MCF-7, in vivo. Vps34 inhibitor significantly potentiated cytotoxicity of Sunitinib and Erlotinib in MCF-7 and MDA-MB-231 in vitro in monolayer cultures and when grown as multicellular spheroids. Our data suggests that inhibition of autophagy significantly improves sensitivity to Sunitinib and Erlotinib and that Vps34 is a promising therapeutic target for combination strategies in breast cancer.
Thalidomide-NH-C6-NH-Boc is a synthesized E3 ligase ligand-linker conjugate containing the cereblon ligand derived from Thalidomide and a linker utilized in the synthesis of MI-389 (compound 22). MI-389 is a highly effective phthalimide PROTAC degrader developed from the multi-targeted receptor tyrosine kinase inhibitor sunitinib.
