Description:	ZL006 is a potent inhibitor of nNOS/PSD-95 interaction, and inhibits NMDA receptor-mediated NO synthesis.
In Vivo:	Compared with P-LPs/ZL006 and free ZL006, T7-P-LPs/ZL006 exhibits a significant increase of drug accumulation in the brain tissue due to its better brain targeting delivery. Compared with free ZL006, P-LPs/ZL006 and T7-P-LPs/ZL006 exhibit a significant decrease of drug accumulation in the liver and kidney[1].
In Vitro:	ZL006 presents little cytotoxicity, and a growth inhibition of BCECs is not found at low concentration of 0.001, 0.01, 0.1, 1 and 10 μg/mL. The cytotoxicity of T7-P-LPs/ZL006 is significantly enhanced at the concentration of 10 μg/mL. Cellular uptake of ZL006 loads P-LPs and T7-P-LPs after incubation for 0.5 h at the concentrations range from 100 μg/mL to 600 μg/mL in BCECs[1]. ZL006 does not inhibit the nNOS-PDZ/PSD-95-PDZ interaction, or perturb the nNOS β-finger[2].
Cell Assay:	BCECs are seeded in 96-well plates in 200 μL of DMEM medium to obtain a concentration of 2000 cells per well, and incubated for 24 h. The medium in each well is then incubated for 72 h with 200 μL medium containing blank vehicle, P-LPs/ZL006, T7-P-LPs/ZL006 and ZL006 (free drug dissolved in DMSO) with a series of concentrations ranging from 0.001 to 100 μg/mL. The MTT absorbance at 570 nm of each well is measured by a microplate reader.
Animal Administration:	ICR mice weighting 20 ± 2 g are divided into three groups at random (n=12). Free ZL006, P-LPs/ZL006 and T7-P-LPs/ZL006 (all containing ZL006 4 mg/kg) are administered to each group through intravenous route, respectively. At designated time intervals (0.5, 1 and 2 h), the mice are executed and the major organs samples including brain, heart, liver, spleen, lung and kidney are collected. Before pretreatment, these tissues are rinsed with cold saline solution to remove the blood and then blotted with paper towel. Protein precipitation of the samples is performed before analysis. Then the samples are injected into the LC-MS/MS systems for analysis. The LC-MS/MS system consists of an Agilent Series 1200 HPLC system and a 6410 Triple Quad LC/MS mass spectrometer. The data is collected and processed using the Agilent MassHunter Workstation Software.

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.
