Field of application
This Cyanine5 NHS ester, also known as Cy5 NHS ester, is a reactive dye for the labeling of amino-groups in peptides, proteins, and oligonucleotides. This dye requires a small amount of organic co-solvent to be used in labeling reactions. This reagent is ideal for very cost-efficient labeling of soluble proteins as well as all kinds of peptides and oligonucleotides. This reagent also works well in organic solvents for small molecule labeling.

DC31074 Isopropyl myristate Isopropyl myristate is the ester of isopropyl alcohol and myristic acid.
DC75868 AZ14133346 AZ14133346 (compound 36) is a potent and selective inhibitor of EGFR Exon20 insertions, with the IC50 of 85 nM. AZ14133346 plays an important role in cancer research.
DC75865 TI17 ​​TI17​​ represents a novel class of targeted anticancer agents that specifically disrupt DNA damage repair mechanisms in malignant cells.
DC75816 Nisoxetine Nisoxetine acts as a highly selective and potent noradrenaline transporter (NET) antagonist, exhibiting a binding affinity (Kd) of 0.76 nM. In addition to its antidepressant properties, nisoxetine functions as a local anesthetic by inhibiting voltage-gated sodium channels. This dual pharmacological activity makes it a compound of interest for both neurological and pain management research.
DC75202 Fosaprepitant free acid Fosaprepitant, also known as MK0517, is an antiemetic drug, administered intravenously. It is a prodrug of aprepitant. Fosaprepitant was developed by Merck & Co. and was approved. It is a prodrug of Aprepitant. It aids in the prevention of acute and delayed nausea and vomiting associated with chemotherapy treatment. Fosaprepitant is a weak inhibitor of CYP3A4, and aprepitant, the active moiety, is a substrate, inhibitor, and inducer of CYP3A4
DC74684 ZH8667 ZH8667 is a trace amine-associated receptor 1 (TAAR1)–Gs agonist.
DC74646 EB-PSMA-617 EB-PSMA-617 is an Evans blue-modified prostate-specific membrane antigen (PSMA) 617 ligand for making 177Lu-EB-PSMA, which is potential useful for Metastatic Castration-Resistant Prostate Cancer.
DC74641 HC-258 HC-258 is a Covalent Acrylamide TEAD Inhibitor That Reduces Gene Expression and Cell Migration. HC-258 reduces the CTGF, CYR61, AXL, and NF2 transcript levels and inhibits the migration of MDA-MB-231 breast cancer cells. Co-crystallization with hTEAD2 confirmed that HC-258 binds within TEAD’s PA pocket, where it forms a covalent bond with its cysteine.
DC74639 Oligopeptide-10 Oligopeptide-10, also known as granactive oligopeptide-10, is a synthetic bio-active peptide composed of 15 amino acids. it can help manage acne-causing bacteria, both on its own and in conjunction with anti-acne superstar exfoliant salicylic acid.
DC74638 GLPG3667 GLPG3667 is an oral, reversible, and selective tyrosine kinase 2 (TYK2) inhibitor. It is being developed to treat inflammatory and auto-immune diseases. Biochemical assays showed that GLPG3667 displayed nanomolar potency on TYK2 with a selectivity over other JAK kinases >3-fold. In human PBMC, GLPG3667 showed comparable potency on the IFNα and IL-23 pathways (around 50 nM). Selectivity for TYK2 on the IFNα pathway was >14-fold and >19-fold toward the IL-2 and GM-CSF pathways in human PBMC and whole blood, respectively. Dermal ear inflammation in a mouse model of psoriasis driven by IL-23 was prevented by GLPG3667 with a minimal effective dose of 3 mg/kg given orally once daily. This effect was associated with a decrease in neutrophil infiltration and STAT3 phosphorylation at sites of inflammation. In healthy HV, GLPG3667 completely inhibited IFNα-induced STAT1 and STAT3 phosphorylation but did not impact IL-2- and GM-CSF-induced STAT5 phosphorylation.
