Biological Activity
JHU395 (10 μM; 6 hours) significantly increases the relative abundance of PRPP and XMP in human sNF96.2 and JH-2-002 MPNST cells[1].
JHU395 (10 μM; 6 hours) reduces de novo purine synthesis in human sNF96.2 MPNST cells, as shown by a >25% reduction in 14C-glycine incorporation into DNA and RNA[1].
JHU395 (0.1-100 μM; 72 hours) partially inhibits growth of human sNF96.2, JH-2-002, and JH-2-031 MPNST cells with IC50 values of 3.48 μM, 2.40 μM, and 6.34 μM, respectively[1].
JHU395 (1 μM) partially inhibits colony formation in human JH-2-002 MPNST cells, and its inhibitory potency is enhanced when combined with 10 μM Pro-905, reducing colony formation by ~80%[1].
JHU395 (individual doses; 72 h) potently inhibits the growth of human sNF96.2 and sNF02.2 MPNST cells with IC50 values of 4.6 μM and 1.5 μM, respectively, while minimally affecting immortalized healthy ipn02.32λ Schwann cells; this growth inhibition is partially rescued by 100 μM guanosine monophosphate supplementation in sNF96.2 cells[2].
JHU395 (1-2 μM; 72 h) significantly reduces proliferation in D283MED and D425MED MYC-amplified medulloblastoma cell lines after 72 hours of treatment[3].
JHU395 potently inhibits the growth of high MYC human neural stem cells with an IC50 of 0.5 μM, which is 70-fold more potent than its activity against low MYC human neural stem cells (IC50 = 35 μM)[3].
JHU395 (20 μM; 1 h) delivers DON efficiently to human sNF96.2 MPNST cells in a plasma suspension, with 92% of total measured DON localized to cells after 1 hour of incubation with 20 μM JHU395[2].
