NSD2-IN-6 is a selective and orally active NSD2 inhibitor with IC50s of 3.8  and 274 nM for NSD2 and NSD1 respectively. NSD2-IN-6 reduces H3K36me2 levels, reverses cell plasticity by restoring the androgen receptor (AR) signaling pathway. NSD2-IN-6 reduces a shift from cluster 2 and 3 states towards the cluster 1 state in organoids. NSD2-IN-6 exerts antitumor activity by reversing tumor cell plasticity, suppressing growth, and promoting apoptosis in vivo. NSD2-IN-6 can be used for prostate cancer research.

In Vitro

NSD2-IN-6 (compound NSD2i) shows a substantial reduction in H3K36me2 domains in NPPO-1NE organoids[1].
NSD2-IN-6 results a substantial shift from cluster 2 and 3 states towards the cluster 1 state and enrichment of canonical AR target expression in NPPO-1NE organoids[1].
NSD2-IN-6 has little or no effect on AR expression in non-neuroendocrine organoids with combined Enzalutamide [1].
NSD2-IN-6 (1 µM, 17 days) increases sensitivity to enzalutamide in NPPO-1NE, NPPO-2, NPPO-4 and NPPO-6 organoids with EC50 values of 0.34, 2.7, 1.6 and 20 µM respectively[1].
NSD2-IN-6 (0.3-10 µM, 26 days ) not affect on NSD2 knockout NPPO-1 and NPPO-2 organoids, has a slight effect on NSD2 knockout MSKPCa10[1].
NSD2-IN-6 (10 µM, 21 days) reduces H3K36me2 expression and modest upregulates H3K27me3 in MSKPCa10, MSKPCa14, WCM154, WCM1262 and MSKPCa2 human CRPC organoid lines, loss the lineage marker CD56 and upregulates AR in WCM1262 human CRPC organoid lines, results a reduction in organoid size and immunostaining for cleaved caspase 3 in MSKPCa2 organoids[1].
NSD2-IN-6 (0.3-10 µM, 21 days) lead a decreasing cell viability after enzalutamide treatment, a high Bliss synergy score and a concentration-dependent induction of apoptosis in MSKPCa10, MSKPCa14, WCM154, WCM1262 and MSKPCa2 human CRPC organoid lines when combinate with Enzalutamide [1].

Apoptosis Analysis[1]

Cell Line: H3K27me3 in MSKPCa10, MSKPCa14, WCM154, WCM1262 and MSKPCa2 human CRPC organoid lines
Concentration: 0.3, 1, 3 and 10 μM
Incubation Time: 21 days
Result: Significantly increased caspase 3 and caspase 7 activity in a concentration-dependent manner.
In Vivo

NSD2-IN-6 (compound NSD2i) (75-300 mg/kg, p.o.,once daily for 5 days) reduces H3K36me2 levels in mice xenografts of human prostate organoids[1].
NSD2-IN-6 (150 mg/kg, p.o., daily for 42 days) exerts antitumor activity by by reversing plasticity, suppressing growth and promoting tumour cell apoptosis in mice xenografts of human prostate organoids[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.
