543

DMP-543 (XR-543) is a KV7 channel blocker that enhances neurotransmitter release.

PF-543 Citrate (Sphingosine Kinase 1 Inhibitor II Citrate) is a selective and potent inhibitor of sphingosine kinase 1 (SPHK1) and is an efficient inhibitor of 1-phosphate sphingosine (S1P) formation. It possesses anticancer, antifibrotic, and anti-inflammatory activities and can be used in research on colorectal cancer.

PF-543 (Sphingosine Kinase 1 Inhibitor II), a novel sphingosine-competitive inhibitor of SphK1, inhibits SphK1 with IC50 of 2.0 nM and Ki of 3.6 nM.

YM543 free base, a potent and orally active sodium-glucose cotransporter (SGLT) 2 inhibitor, effectively reduces blood glucose levels and is suitable for diabetes research.

YM-543, also known as ASP-543, is a selective SGLT2 inhibitor. Sodium-glucose cotransporter 2 (SGLT2) is a specifically expressed transporter in the kidney that plays an important role in renal glucose reabsorption, and its inhibition may present a novel therapeutic strategy for treating diabetes. YM543 potently and selectively inhibited mouse and human SGLT2 activities at nanomolar ranges. In vivo single oral administration of YM543 dose-dependently and significantly reduced blood glucose levels and improved glucose tolerance with a concomitant increase in urinary glucose excretion in KK/Ay type 2 diabetic mice, effects that were sustained even after 12 h.

PF-543 hydrochloride (PF-543) inhibits SphK1 with a K(i) of 3.6 nM, is sphingosine-competitive and is more than 100-fold selective for SphK1 over the SphK2 isoform.

UCF 101 is a specific inhibitor of HtrA2 and reduces apoptosis in PC12 cells.

Varlitinib Tosylate is a selective and potent inhibitor of ErbB1(EGFR) and ErbB2(HER2).

BMS-986122 is a IRAK4 Inhibitor. BMS-986126 attenuates Disease in Murine Lupus Models and Demonstrates Steroid Sparing Activity. BMS-986126 inhibited TLR7- and TLR9-dependent responses using cells derived from lupus patients, suggesting that inhibition of IRAK4 has the potential for therapeutic benefit in treating lupus.

VHF 543, Amine is a potent ligand for the WD40 repeat domain (WDR) of DCAF1 (Kd = 31 nM measured by surface plasmon resonance). VHF 543, Amine carries a primary amine functional group handle that allows for rapid binding to linker/target protein ligands.

GAD65 (524-543) is a biologically active peptide comprising amino acids 524 to 543 of glutamic acid decarboxylase 65 (GAD65). It represents an early islet antigen fragment that elicits proliferative T cell responses in the non-obese diabetic (NOD) mouse model, instrumental in spontaneous autoimmune diabetes research. The peptide serves as a specific, possibly low-affinity stimulant for the diabetogenic T cell clone BDC2.5. Notably, immunization with GAD65 (524-543) heightens NOD mice's vulnerability to type 1 diabetes when subjected to the adoptive transfer of BDC2.5 T cells.

YM-543, a sodium-glucose transporter 2 (SGLT-2) inhibitor, is used potentially for the treatment of type 2 diabetes.

Collagen type IV alpha1 (531-543) is a protein that in humans is encoded by the COL4A1 gene on chromosome 13. It is ubiquitously expressed in many tissues and cell types. COL4A1 is a subunit of type IV collagen and plays a role in angiogenesis.

PRT543 is a potent selective inhibitor of the protein arginine methyltransferase 5 (PRMT5), showing a wide range of antitumor activities in vitro and in vivo. The compound also showed an inhibitory effect on methyltransferase activity of the PRMT5/MEP50 complex with an IC50 value of 10.8 nM.

CGS 15435 is a potent thromboxen (TxA2) synthetase inhibitor (IC50: 1 nM). CGS 15435 acts on PGI2 synthase, cyclooxygenase and liposynthase with much less selectivity than on thromboxin synthase.

PHA 543613 is a specific agonist of α7 nAChR (Ki = 8.8 nM) and can be used in studies about the cognitive deficits of Alzheimer's disease and schizophrenia.

Org 25543 hydrochloride is a potent and selective glycine transporter type 2 (GlyT2) inhibitor (IC50 = 16 nM for hGlyT2). Displays no activity at GlyT1 or 56 other common biological targets (≥ 100 μM), in a glycine uptake assay in CHO cells.

Org 25543 is the development of an N-Acyl amino acid that selectively inhibits the glycine transporter 2 to produce analgesia in a rat model of chronic pain.

GW 284543 hydrochloride is a selective inhibitor of MEK5 .

Gln-AMS(TFA) inhibits glutaminyl-tRNA synthetase (GlnRS) with a Ki of 1.32 μM. Gln-AMS (TFA) is a type Ia aminoacyl-tRNA synthetase (AARS) inhibitor.

INCB054329 Racemate is an inhibitor of BET protein.

LY285434 is an angiotensin II receptor antagonist [suitable].

TMU 35435 is an inhibitor of histone deacetylases (HDAC). It enhances radiosensitivity by inducing the accumulation of misfolded proteins and autophagy (autophagy) in TNBC, and inhibits the NHEJ pathway through ubiquitination of the catalytic subunit of DNA-dependent protein kinase (DNA-PKcs).

BI1543673 is an inhibitor of interleukin-1 receptor-associated kinase 4 (IRAK4). It can diminish inflammatory responses in human lung tissue stimulated by TLR4 and TLR7/8. Additionally, BI1543673 reduces inflammatory signaling in a mouse lung inflammation model induced by LPS.
