PROTAC CARM1/IKZF3 degrader-1 (Compound 074) 抑制CARM1并减少其底物BAF155的甲基化。它是通过CRBN依赖途径降解IKZF 1/3的PROTAC降解剂,抑制MYC蛋白表达,以减缓多发性骨髓瘤细胞的增殖,并诱导H929细胞凋亡 (apoptosis)。此外,该化合物能够克服对免疫调节药物(IMiD,如泊马度胺)的耐药性,适用于癌症和免疫学研究。(Pink: ligand for target protein CARM1/IKZF3 ligand 1; Active form of target protein ligand: EZM 2302; Black: linker; Blue: ligand for E3 ligase Cereblon Thalidomide 4-fluoride)
Gusacitinib, also known as ASN-002 and EN-3351, is a potent dual inhibitor of SYK/JAK kinases. ASN002 showed strong antitumor activity in both hematological and solid tumor xenograft models. ASN002 strongly suppressed the SYK and JAK family kinase signaling pathways as measured in pLAT and pSTAT assays, respectively. When profiled in a panel of 178 cell lines, ASN002 showed strong anti-proliferative activity in many lymphoid/leukemia cell lines, including SU-DHL-6, SU-DHL-4, OCI-LY10, H929 and Pfeiffer.
