ARD-2128 has the potential for the research of the prostate cancer.

Leelamine hydrochloride is an orally active weakly basic amine that inhibits NPC1 and the androgen receptor AR-V7, and acts as a cannabinoid receptor agonist. Leelamine hydrochloride also functions as a lysosome affinity agent that blocks endocytosis, disrupts autophagic flux and cholesterol transport, thereby altering the RTK-AKT/STAT/MAPK signaling cascade. Leelamine hydrochloride induces cancer cell death and autophagosome accumulation, and can be used in research related to melanoma, castration-resistant prostate cancer and breast cancer.

SC428 is an androgen receptor (AR) inhibitor that targets the N-terminal domain. SC428 potently decrease the transactivation of (AR)-V7, (AR)v567es, as well as full-length ( AR ) (AR-FL) and its LBD mutants, substantially. SC428 inhibits androgen-stimulated (AR)-FL nuclear translocation, chromatin binding, and (AR) -regulated gene transcription. SC428 inhibits the proliferation of tumor cells in vitro. SC428 inhibits tumor cell growth by inducing apoptosis in mice transplanted with 22RV1.

CLP-3094 is a potent BF3 (binding function 3)-directed inhibitor of the androgen receptor (AR). CLP-3094 inhibits AR transcriptional activity (IC₅₀=4 μM). CLP-3094 is a selective, potent GPR142 antagonist.

MK-0773 is a selective androgen receptor modulators (SARMs) that binds to AR with an IC₅₀ of 6.6 nM.

ET516 is a potent inhibitor of Androgen Receptor. ET516 significantly inhibits the proliferation and tumor growth of prostate cancer cells expressing AR-resistant mutants.

ARD-266 is a highly potent and von Hippel-Lindau E3 ligase-based Androgen Receptor (AR) PROTAC degrader. ARD-266 effectively induces degradation of AR protein in AR-positive LNCaP, VCaP, and 22Rv1 prostate cancer cell lines with DC₅₀ values of 0.2-1 nM. ARD-266 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

JJH260 is AIG1inhibitor, and inhibit the fluorophosphonate reactivity and fatty acid esters of hydroxy fatty acid (FAHFA) hydrolysis activity of AIG1in HEK293T cells, with IC₅₀ values of 0.50 μM and 0.57 μM, respectively.

Meloside A (Isovitexin 2''-O-glucoside) is a flavonoid with antioxidant activity. Meloside A can inhibit cell apoptosis and ROS production. Meloside A can inhibit androgen receptor (AR) nuclear translocation and AR protein expression. Meloside A can reduce IL-6, TGF-β1 and DKK-1 levels. Meloside A can be used for the researches of inflammation and endocrinology, such as hair loss.

Trisdecanoin (Tricaprin; Glyceryl tridecanoate) is an orally available precursor of decanoic acid (DA precursor) that can be hydrolyzed to decanoic acid. Trisdecanoin and its metabolite capric acid not only provide the body with a quick source of energy, but can also affect lipid metabolism. Trisdecanoin is a major component of medium chain triglycerides (MCT), which has preventive or inhibitory properties for abdominal aortic aneurysms (AAA), inhibition of cardiovascular disease, and anti-androgen (NSAA) and anti-hyperglycemic properties. Trisdecanoin can be used as an additive in food, medicine and cosmetics.

Isosilybin B is a flavonolignan. Isosilybin B can be isolated from Silybum marianum. Isosilybin B can regulate cell cycle-related proteins (e.g., reduce cyclins (D3, D1, A, E), Cdk4, Cdk2, Cdc25A), and activate Caspases (Caspase-9 and Caspase-3).
