Sorafenib D4 is the deuterium labeled Sorafenib. Sorafenib is an inhibitor of multikinase (Raf-1, B-Raf, and VEGFR-3 IC50s of 6 nM, 20 nM, and 22 nM, respectively).
Sorafenib N-oxide is an active metabolite of sorafenib , an inhibitor of Raf-1, B-RAF, and receptor tyrosine kinases. Sorafenib N-oxide inhibits FLT3 that contains the internal tandem duplication mutation (FLT3-ITD; Kd = 70 nM) and inhibits proliferation of MV4-11 acute myeloid leukemia (AML) cells expressing FLT3-ITD (IC50 = 25.8 nM). It is selective for AML cell lines containing FLT3-ITD over lines containing wild-type FLT3 (IC50s = 3.9-13.3 μM). Sorafenib N-oxide is also a linear-mixed inhibitor of the cytochrome P450 (CYP) isoform CYP3A4 (Ki = 15 μM in human liver microsomes).
SC-2001 is a MCL-1 inhibitor. SC-2001 inhibits STAT3 phosphorylation through enhancing SHP-1 expression and induces apoptosis in human breast cancer cells. SC-2001 overcomes STAT3-mediated sorafenib resistance through RFX-1/SHP-1 activation in hepatocellu
CAY10773 is a derivative of the ferroptosis inducer sorafenib .1It selectively inhibits proliferation of BEL-7402, MGC803, and T24 bladder cancer cells (IC50s = 5.77, 5.21 and 3.97 μM, respectively) over non-cancerous HCV-29 cells (IC50= 23.19 μM). CAY10773 induces apoptosis in T24 cells when used at concentrations ranging from 2 to 6 μM but induces ferroptosis at concentrations greater than or equal to 6 μM with 10 hour or longer incubation times. It increases the production of reactive oxygen species (ROS) and decreases the mitochondrial membrane potential in T24 cells. CAY10773 (≥6 μM) also induces autophagy with incubation times longer than eight hours.
