Glutaminase-IN-1 (CB839 derivative), a CB839 derivative, is an allosteric inhibitor of 1,3,4-selenadiazole-containing kidney-type glutaminase (KGA), with an IC₅₀ of 1 nM. Glutaminase-IN-1 (CB839 derivative) shows improved cellular uptake and antitumor activity.

IC50: 1 nM (KGA)^[1].

Glutaminase-IN-1 (CPD20), a CB839 derivative, is an allosteric inhibitor of 1,3,4-selenadiazole-containing kidney-type glutaminase (KGA), with an IC₅₀ of 1 nM. Glutaminase-IN-1 shows improved cellular uptake and antitumor activity. The IC₅₀ values of Glutaminase-IN-1 are 17 nM, 6.78 μM, 19 nM and 9 nM in A549, H2, Caki-1 and HCT116 cell lines, respectively. Glutaminase-IN-1 has better KGA inhibitory activity than the corresponding BPTES and CB839^[1].

Glutaminase-IN-1(10 mg/kg, s.c.) reduced the size and weight of the HCT116 tumor, and statistical analysis showed that the 40% reduction in tumor weight by CPD20 is statistically significant. Glutaminase-IN-1 could statistically significantly prolong the survival of H22-bearing mice^[1].
