SARD279
Based on 1 Customer Validation
SARD279 is a PROTAC degrader of androgen receptor (AR). SARD279 binds to AR, recruits HSP70, mediates ubiquitin-dependent proteasomal degradation, and competitively inhibits the transactivation of AR. SARD279 exhibits antiproliferative activity in AR-dependent prostate cancer cells and castration-resistant prostate cancer cells, including those harboring the ARF876L mutation. SARD279 can be used in studies related to prostate cancer and castration-resistant prostate cancer.

SARD279 (0-10000 nM; 20 h) degrades androgen receptor in VCaP prostate cancer cells with a DC50 of 1099 nM and a maximum degradation of 69% after 20 hours of treatment[1].
SARD279 (156 nM-10 μM) induces HSP70-dependent, selective degradation of androgen receptor (AR) in LNCaP human prostate cancer cells, inhibits AR-dependent gene expression with an IC50 of 156 nM, and exerts antiproliferative effects in AR-dependent and castration-resistant prostate cancer cell lines[2].
SARD279 (10 μM; 24 h) mediates Hsp70-associated degradation of androgen receptor in LNCaP human prostate tumor cells with a DC50 of 1 μM and achieves complete AR degradation at 10 μM[3].
SARD279 (500 nM-10 μM; 24 h) induces proteasome-dependent degradation of the androgen receptor in LNCaP human prostate tumor cells with a DC50 of 1 μM, and this activity is enhanced by Hsp90 inhibition[5].
SARD279 antagonizes androgen receptor target gene expression in AR-overexpressing LNCaP-AR human prostate tumor cells without exhibiting agonist activity[5].
SARD279 (3 μM; 9 days) specifically suppresses proliferation of AR-dependent LNCaP human prostate tumor cells, with no effect on AR-independent cell lines[5].
SARD279 (0.01-10 μM; 7 days) retains dose-dependent antiproliferative activity in LNCaP human prostate tumor cells in the presence of 1 nM R1881, overcoming androgen-mediated resistance to MDV3100[5].
SARD279 (0.01-3 μM; 7 days) exerts dose-dependent antiproliferative effects in MDV3100-resistant LNCaP/ARF876L human prostate tumor cells, overcoming F876L mutation-mediated resistance[5].
Pre-fused SARD279 (0.03-0.5 μM; 24 h) (with HSP70, delivered via 80-O14B LNPs) potently degrades androgen receptor in LNCaP cells with a DC50 of ~0.06 μM, while free SARD279 (0.12-0.5 μM; 24 h) shows no AR degradation at concentrations up to 0.5 μM[4].
SARD279 binds directly to the androgen receptor with reduced affinity (37-fold lower than RU59063)[5].
SARD279 blocks androgen receptor transactivation in 293 cells with an IC50 of 156 nM[5].
