enzalutamide

Enzalutamide (MDV3100) is an androgen receptor (AR) antagonist (IC50=36 nM in LNCaP) that activates autophagy, exhibits antitumor activity, and is commonly used in treating desmoplasia-resistant prostate cancer.

N-desmethyl Enzalutamide (N-desmethyl MDV 3100) is the active Enzalutamide metabolite.It is the active metabolite of Enzalutamide. N-desmethyl Enzalutamide demonstrates primary and secondary pharmacodynamics of similar potency to Enzalutamide and circulates at approximately the same plasma concentrations as enzalutamide.

Enzalutamide D3 is a deuterium labeled Enzalutamide . Enzalutamide is an androgen receptor (AR) antagonist with an IC50 of 36 nM in LNCaP prostate cells.

Enzalutamide carboxylic acid is an inactive metabolite of Enzalutamide. Enzalutamide carboxylic acid D6 is the deuterium labeled Enzalutamide carboxylic acid (MDV3100 carboxylic acid).

N-desmethyl Enzalutamide D6 is a deuterium labeled N-desmethyl Enzalutamide.

Enzalutamide carboxylic acid is an antagonist of androgen receptor (AR) .

Enzalutamide-d6 Carboxylic Acid is a deuterated compound of Enzalutamide Carboxylic Acid. Enzalutamide Carboxylic Acid has a CAS number of 1242137-15-0. Enzalutamide carboxylic acid is an antagonist of androgen receptor (AR) .

VPC-13163 (NSC-52361) has strong anti-proliferative activity against LNCaP and Enzalutamide-resistant prostate cancer cell lines (MR49F) whereas it did not affect the growth of AR independent PC3 cell line. It also inhibits Prostate Specific Antigen (PSA) in both LNCaP and MR49F and reduces expression of AR target genes, PSA and TMPRSS2. These findings suggest that VPC-13566 exhibits AR BF3 specific mechanism of action.

ZEN-3694 (ZEN 3694) is a bromo-structural domain extra-terminal inhibitor (BETi) with activity in androgen signaling inhibitor (ASI) resistance models and can be used in combination with enzalutamide to study metastatic desmoplasia-resistant prostate cancer.

UT-34 is a selective and orally active antagonist of second-generation pan-androgen receptor (AR) and degrader(IC50s of 211.7 nM, 262.4 nM and 215.7 nM for wild-type, F876L and W741L AR, respectively), and has anti-prostate cancer efficacy.

ARCC-4 is an enzalutamide-based von Hippel-Lindau (VHL)-recruiting AR PROTAC and outperforms enzalutamide and it is a low-nanomolar androgen receptor (AR) degrader based on PROTAC, with a DC50 of 5 nM. ARCC-4 effectively degrades clinically relevant AR mutants associated with antiandrogen therapy[1].

FL442 is an Androgen Receptor (AR) modulator. This compound exhibits potent inhibitory effects in AR-dependent prostate cancer cells, showing similar suppression efficiency to the traditional antiandrogen drugs Bicalutamide and Enzalutamide. It also maintains antiandrogen activity against the Enzalutamide-resistant AR mutant F876L. The pharmacokinetic properties of FL442 in mice reveal a longer half-life (8 hours), excellent targeting (prostate tissue), and metabolic stability. Additionally, it is effective at inhibiting LNCaP tumor growth at low plasma concentrations (30 ng mL).

LX1, an anti-prostate cancer compound, specifically targets the androgen receptor (AR), AR variants, and the steroidogenic enzyme AKR1C3. It inhibits AKR1C3's enzymatic function, decreases the conversion of androstenedione to testosterone, and reduces the expression of both AR and AR-V7, subsequently downregulating their target genes. Additionally, LX1 is effective in overcoming tumor cell resistance to Enzalutamide, and when combined with Enzalutamide, it further suppresses tumor growth.

(+)-JJ-74-138 is a novel non-competitive androgen receptor (AR) antagonist capable of inhibiting enzalutamide-resistant castration-resistant prostate cancer (CRPC).

AR antagonist 9 is an orally active, selective androgen receptor (AR) antagonist that inhibits cancer by disrupting the formation of AR ligand-binding domain dimers, showing potential in overcoming drug resistance in prostate cancer (PCa). Its antagonistic activity against AR has an IC50 of 0.051 μM, comparable to Enzalutamide (IC50= 0.060 μM). This compound demonstrates superior inhibitory effects on ARF876L T877A and ARW741C mutants compared to Enzalutamide. Additionally, AR antagonist 9 possesses favorable pharmacokinetic properties, with an oral bioavailability (F) of 66.24% in rats, and significantly inhibits tumor growth in LNCaP xenograft mouse models upon oral administration. AR antagonist 9 holds promise for research in overcoming PCa resistance.

EPI-7170 is a ralaniten analogue and a potent antagonist of the androgen receptor N-terminal structural domain, blocking the transcriptional activity of the full-length AR (FL-AR) and AR splice variants (AR-Vs). EPI-7170 exhibits antitumor activity against enzalutamide resistant debulking resistant prostate cancer (CRPC).

YXG-158 (Compound 23-h), an orally active androgen receptor (AR) degrader and cytochrome P450 17A1 (CYP17A1) inhibitor, exhibits AR degradation with a DC50 of 1.28 μM and CYP17A1 inhibition with an IC50 of 100 nM. It is under investigation for potential use in research on enzalutamide-resistant prostate cancer [1].

GA32 (compound 58r) is a potent androgen receptor (AR) glucocorticoid receptor (GR) dual inhibitor with IC50 values of 0.13 μM and 0.83 μM for AR and GR, respectively. GA32 inhibits the proliferation of Enzalutamide-resistant, castration-resistant prostate cancer both in vitro and in vivo [1].
