Description:	Sacubitrilat is an active neprilysin (NEP) inhibitor.
Target:	Neprilysin[1]
In Vivo:	Pharmacokinetics of Sacubitril, Sacubitrilat (LBQ657), and valsartan following the administration of single oral doses of LCZ696 400 or 1200 mg under fasting condition are summarized. The mean plasma concentrations of Sacubitril increases rapidly with a median Tmax of 0.52 h for the 400 mg dose and 1.05 h for the 1200 mg dose, followed by Sacubitrilat, with the corresponding Tmax values of 2.07 and 3.05 h, respectively. The median Tmax for valsartan is 2.07 h for both the LCZ696 400 mg and 1200 mg doses. The Cmax of Sacubitrilat shows a dose proportional increase, while the Cmax of Sacubitril and Valsartan shows less than proportional increases between the doses. The arithmetic mean AUC0-24 h and AUClast for Sacubitril and Sacubitrilat increases approximately dose proportionally, but shows less than dose proportional increase for Valsartan[2].
In Vitro:	Sacubitrilat (LBQ657) is a single diastereomer with specific stereocenters. Sacubitrilat is bound to the active site of NEP by an intricate network of interactions that involves all functional groups of the compound giving rise to the high inhibitory potency of 5 nM[1].

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.
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.
DC77721	SLW131	SLW131 (Compound 10) is the antagonist for CCR7 with a good affinity of Ki of 9.85 nM. SLW131 inhibits CCL19-induced Go protein activation with an IC50 of 29.4 μM, inhibits β-arrestin2 recruitment with an IC50 of 6.0 μM. SLW131 inhibits CCL19-induced cell morphological changes in primary BMDCs, and CCR7-mediated migration in mouse CD4+ T cell.
