SMD-6346
SMD-6346 is an orally active SMARCA2 PROTAC degrader with a DC50 of 3.3 nM. SMD-6346 induces SMARCA2 degradation and exhibits extremely low activity against SMARCA4. SMD-6346 inhibits the growth of SMARCA4-deficient cancer cells and suppresses tumor growth in mouse xenograft models. SMD-6346 can be used for the research of non-small cell lung cancer.
(Pink: SMARCA2 ligand (HY-170817); Blue: Cereblon ligand (HY-W440247); Black: linker).

SMARCA2 3.3 nM (DC50) |
SMD-6346 (24 h) potently and selectively degrades SMARCA2 (DC50 = 3.3 nM, Dmax = 91%) in CRISPR/Cas9-modified HeLa cells expressing HiBiT-tagged SMARCA2 and SMARCA4, while it exhibits much weaker degrading activity against SMARCA4 (DC50 > 1000 nM, Dmax = 46%)[1].
SMD-6346 (0.1-10000 nM; 24 h) potently induces nearly complete degradation of SMARCA2 (DC50 is 6 nM in H838 cells, 22 nM in SK-MEL-5 cells, and 11 nM in 22Rv1 cells; Dmax reaches > 95% in all three cell lines), and exhibits over 900-fold selectivity for SMARCA2 over SMARCA4 in 22Rv1 cells[1].
SMD-6346 (0-1 μM; 7 days) potently inhibits the growth of SMARCA4-deficient cancer cell lines (with a GI50 of 4.0 nM in SK-Mel-5, 19 nM in H838, and 78 nM in H1944), while it exhibits only extremely low activity in SMARCA4 wild-type cell lines (GI50 > 1000 nM)[1].

Cell Line:H838 (SMARCA4-deficient lung cancer), SK-MEL-5 (SMARCA4-deficient melanoma), 22Rv1 (SMARCA2/4 wild-type prostate cancer)
-
Concentration:0.1, 0.3, 1, 3, 10, 30, 100, 300, 1000, 3000 and 10000 nM
-
Incubation Time:24 h
-
Result:Induced near-complete SMARCA2 degradation (Dmax > 95%) with a DC50 of 6 nM in H838 cells.
Achieved near-complete SMARCA2 degradation (Dmax > 95%) with a DC50 of 22 nM in SK-MEL-5 cells.
Potently degraded SMARCA2 (DC50 = 11 nM, Dmax > 95%) but only modestly reduced SMARCA4 levels (Dmax = 38% even at 10 μM) in 22Rv1 cells.
Resulted in a > 900-fold degradation selectivity for SMARCA2 over SMARCA4 in 22Rv1 cells.
SMD-6346 (5-10 mg/kg; p.o.; administered 5 days per week for 2 consecutive weeks) inhibits tumor growth in H838 xenograft mice[1].
