Description:	VLX600 is an iron-chelating inhibitor of oxidative phosphorylation (OXPHOS). VLX600 causes mitochondrial dysfunction and induces a strong shift to glycolysis. VLX600 displays selective cytotoxic activity against malignant cell and induces autophagy. Anticancer activity[1][2].
In Vivo:	VLX600 (16 mg/kg; i.v.; every third day for 16 days) shows anti-tumor activity in human tumor xenografts[2]. Animal Model: NMRI nu/nu mice (HCT116 and HT29 colon cancer xenografts)[2] Dosage: 16 mg/kg Administration: Intravenously; every third day for 16 days Result: Anti-tumor activity was observed in both HCT116 and HT29 colon cancer xenografts.
In Vitro:	VLX600 (6 μM; 72 hours) induces an autophagic response[2]. VLX600 is cytotoxic to HCT116 spheroids. VLX600 induces a HIF-1α-dependent glycolytic response. VLX600 inhibits oxygen consumption in HCT116 cells. VLX600 inhibits phosphorylation of the mTOR downstream effectors 4EBP1 and p70-S6K by an HIF-1α-independent mechanism. VLX600 preferentially leads to decreased ATP levels in cancer but not normal cells[2]. Cell Proliferation Assay[2] Cell Line: HCT116, HT29, SW620, HT8, DLD and RKO cells Concentration: 0.1, 1, 10, 100μM Incubation Time: 72 hours Result: Inhibited the proliferation of these cells. Western Blot Analysis[2] Cell Line: HCT116 cells Concentration: 6 μM Incubation Time: 72 hours Result: LC3-II was induced.

Cat. No.	Product name	Field of application
DC31079	Abarelix	Abarelix is a synthetic decapeptide and antagonist of naturally occurring gonadotropin-releasing hormone (GnRH). Abarelix directly and competitively binds to and blocks the gonadotropin releasing hormone receptor in the anterior pituitary gland, thereby inhibiting the secretion and release of luteinizing hormone (LH) and follicle stimulating hormone (FSH). In males, the inhibition of LH secretion prevents the release of testosterone. As a result, this may relieve symptoms associated with prostate hypertrophy or prostate cancer, since testosterone is required to sustain prostate growth.
DC31074	Isopropyl myristate	Isopropyl myristate is the ester of isopropyl alcohol and myristic acid.
DC79856	EVT0185	EVT0185 is an orally active ATP citrate lyase (ACLY) inhibitor. EVT0185 is converted to a CoA thioester in the liver by SLC27A2 and interacts with the CoA-binding site of ACLY. EVT0185-CoA inhibits ACLY activity with an IC50 of 2.5 μM. EVT0185 can phenocopy the immune and antitumour effects of genetic ACLY deletion. EVT0185 can increase tumour-infiltrating B cells and chemokine CXCL13 levels. EVT0185 can be used for the research of cancer, such as hepatocellular carcinoma (HCC).
DC79609	NCGC00685960	NCGC00685960 is a Nicotinamide N-methyltransferase (NNMT) inhibitor with an IC50 < 10  nM. NCGC00685960 has potent antitumor activity. NCGC00685960 increases H3K27 trimethylation levels in ovarian cancer cells and inhibits α-SMA expression in NNMT-expressing ovarian fibroblasts. NCGC00685960 reduces 1-MNA levels, reverses SAM and H3K27 hypomethylation and significantly impairs collagen contractility in cancer-associated fibroblasts (CAFs). NCGC00685960 can be used for cancers research.
DC79112	Simepdekinra	Simepdekinra (Compound 221) is a IL-17A modulator with IC50s ≤10  nM and 10-100 nM for IL-17A/A HEK-Blue and IL-17A/F HEK-Blue cells. Simepdekinra can be used for inflammatory diseases such as psoriasis, ankylosing spondylitis and psoriatic arthritis research.
DC78751	RSL3-NH2	RSL3-NH2 is a GPX4 inhibitor and Ferroptosis inducer. RSL3-NH2 can be used as a cytotoxic payload for synthesis of antibody-drug conjugates (ADCs).
DC77831	Vicadrostat	Vicadrostat (compound 29 A) is a potent and selective inhibitor of aldosterone synthase(CYP11B2) with an IC50 of 16 nM. It exhibits potential in renal disease, diabetic nephropathy, cardiovascular diseases and fibrotic disorder research.
DC77813	Zeltociclib	Zeltociclib is a cyclin-dependent kinase inhibitor with antitumor effects.
DC77784	UNC10013	UNC10013 is a SETDB1 allosteric modulator that forms a covalent bond with Cys385 in the 3TD domain, exhibiting negative allosteric regulatory activity. It has a kinact/KI value of 1.0 × 106 M-1*s-1. UNC10013 effectively disrupts SETDB1-mediated Akt methylation and holds potential value for research in cancer and neurodegenerative diseases.
DC77740	T0080	T0080 is a FPR-1 antagonist. T0080 reduces the cell apoptosis, inhibits ROS production and pro-inflammatory cytokines (TNF-α and IL-1β) from plaque macrophages, which attenuates atherosclerotic progression in ApoE−/− mice.
