In Vitro

Voruciclib (0.5-5 µM; 6 hours) shows targeted downregulation of MCL-1 in both ABC and GCB subtypes[1].
Ki values for each target such as CDK9/cyc T2, CDK9/cyc T1, CDK6/cyc D1, CDK4/cyc D1, CDK1/cyc B, and CDK1/cyc A for Voruciclib hydrochloride are 0.626 nM, 1.68 nM, 2.92 nM, 3.96 nM, 5.4 nM, 9.1 nM, respectively[1].

Cell Viability Assay[1]

Cell Line: U2932, RIVA, OCI-LY10 cells (ABC subtype), NU-DHL-1, SU-DHL-4, SU-DHL-6 cells (GCB subtype)
Concentration: 0.5 µM, 1 µM, 2 µM, 3 µM, 4 µM, 5 µM
Incubation Time: 6 hours
Result: Showed targeted downregulation of MCL-1 in both ABC and GCB subtypes.
In Vivo

Combination of Voruciclib hydrochloride (200 mpk; Oral gavage) and Venetoclax (10 mpk, 1 mpk, 50 mpk, 25 mpk in U2932, RIVA, SU-DHL-4 and NU-DHL-1, respectively) leads to enhance tumor growth inhibition compared to either drug alone in U2932, RIVA, SU-DHL-4 (six days per week for 4 weeks), and NU-DHL-1 models (five days per week for 3 weeks) of DLBCL[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
