Field of application
RO-3 is a potent, CNS-penetrant, and orally active P2X3 and P2X2/3 antagonist with pIC50s of 5.9 and 7.0 for human homomultimeric P2X3 and heteromultimeric P2X2/3 receptors, respectively. RO-3 shows selectivity for P2X3 and P2X2/3 over all other functional homomultimeric P2X receptors (IC50 >10 μM at P2X1,2,4,5,7)[1].

Target: pIC50: 5.9 (human homomultimeric P2X3 receptor); 7.0 (human heteromultimeric P2X2/3 receptor)[1]
In Vivo: In a guinea pig ureter-afferent nerve preparation, and mouse bladder-pelvic nerve preparation, RO-3 dose-dependently reduces afferent nerve activity induced by distension or α,β-meATP[1]. RO-3 has activity in several rodent models of pain, as well as in cystometry models optimized to measure various parameters associated with sensory regulation of the micturition reflex[1]. RO-3 has moderate to high metabolic stability in rat and human hepatocytes and liver microsomes, and is highly permeable, orally bioavailable (14%), and has a reasonable in vivo plasma half-life (t1/2=0.41 h) in rats[1].

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.
