YXG-158
YXG‑158 is an orally active, anticancer bifunctional steroid analog with both androgen receptor (AR) degradation activity (DC50 = 1.28 μM) and CYP17A1 inhibitory activity (IC50 = 100 nM). YXG-158 reduces AR protein and mRNA expression via proteasome-dependent degradation, degrades AR-V7, and inhibits CYP17A1 enzymatic activity to block androgen biosynthesis. YXG-158 inhibits the activities of ERα and ERβ, as well as cancer cell proliferation. YXG-158 decreases the weight of androgen-sensitive organs in castrated rats treated with testosterone propionate, downregulates AR protein, reduces PSA levels, and suppresses tumor growth in Enzalutamide (HY-70002)-sensitive and -resistant xenograft models. YXG-158 can be used in prostate cancer-related research.

In Vitro
YXG-158 (compound 23-h) potently inhibits recombinant human CYP17A1 enzyme with an IC50 of 0.100 μM; it suppresses the growth of LNCaP prostate cancer cells with an IC50 of 472.8 nM; it partially inhibits the transcriptional activation of wild-type and mutant ARF876L, ARW741L, and ART877A in dihydrotestosterone-induced HEK293 cells, with IC50 values ranging from 79.75 nM to 389.8 nM[1].
YXG-158 degrades AR protein in LNCaP prostate cancer cells, with a DC50 of 1.28 μM[1].
YXG-158 (1-20 μM; 24 h) induces dose-dependent degradation of full-length AR in LNCaP, VCaP and 22RV1 prostate cancer cells, and reduces AR-V7 levels in 22RV1 cells; it also degrades AR protein in LNCaP prostate cancer cells in a proteasome-dependent manner[1].
YXG-158 (1-20 μM; 48 h) reduces the level of AR mRNA in cultured LNCaP prostate cancer cells in a dose-dependent manner[1].
YXG-158 exerts no significant inhibitory effect on hERG K+ channel and GABAA receptor currents at concentrations up to 40 μM, with an IC50 > 40 μM[1].
YXG-158 exhibits low to moderate inhibitory effects on CYP1A2, CYP2C9, CYP2C19, and CYP2D6 enzymes, and shows submicromolar inhibitory activity against CYP3A4 enzyme[1].
