Description:	Radiprodil (RGH-896) is an orally active and selective NMDA NR2B antagonist. A potential therapeutic agent in treatment of neuropathic pain and possibly other chronic pain conditions[1].
Target:	NMDA NR2B[1].
In Vivo:	Radiprodil could block NMDA currents in Mg2+ insensitive variants, with potencies similar to those obtained without Mg2+[3]. Radiprodil's potency is higher at pH 7.0 than at pH 7.6, suggesting that radiprodil may retain its ability to block glutamate-induced NMDA currents even under acidic conditions that manifest under long term seizures[3].
In Vitro:	Preincubation with Radiprodil (10 nM) restores long-term potentiation (LTP) in the presence of Aβ1-42, 3NTyr10-Aβ and Aβ1-40, but not AβpE3[2]. As for LTP, Radiprodil (10 nM) reverses the synaptic toxicity of 3NTyr-AβAβ1-40 and Aβ1-42 but not that AβpE3-42[2].

Cat. No.	Product name	Field of application
DC82301	IC-8	IC8 is an ionizable cationic lipid. It has been used in combination with other lipids for the formation of lipid nanoparticles (LNPs). Immunization with severe acute respiratory coronavirus 2 (SARS-CoV-2) spike glycoprotein mRNA in IC8- and manganese-containing LNPs induces IgG responses to SARS-CoV-2 Delta and Omicron variants in mice.1 Administration of mRNA encoding B7-H3 X CD3 bispecific T cell engaging (BiTE) antibodies in IC8-containing LNPs reduces tumor growth in MV4-11 and A375 mouse xenograft models.
DC75721	CL2A-SN38 (Govitecan)	CL2A-SN38 is a SN38 derivative with a peptide-linker which can easily react with antibody to form an antibody-drug conjugate (ADC). CL2A-SN-38 is composed of a potent a DNA Topoisomerase I inhibitor SN-38 and a linker CL2A to make antibody drug conjugate (ADC). CL2A-SN-38 provides significant and specific antitumor effects against a range of human solid tumor types. CL2A is a noncleavable complicated PEG8- and triazole-containing PABC-peptide-mc linker. CL2A is cleavable through pH sensitivity, giving rise to bystander effect, and binds the antibody at a cysteine residue via a disulfide bond. .
DC46471	RP101988	RP101988, the major active metabolite of Ozanimod, is a selective, potent S1PR1 (sphingosine-1-phosphate receptor 1) agonist, with EC50s of 0.19 nM and 32.8 nM for S1PR1 and S1PR5, respectivlely.
DC37901	PD-173212	PD-173212 is a small molecule N-type calcium channel blocker.
DC37333	N,N-Diethyl-p-toluamide	N,N-Diethyl-p-toluamide is a mosquito repellent.
DC37321	AI3-15902	AI3-15902 is a biochemical.
DC37283	Methyl phenylcarbamate	Methyl phenylcarbamate is a biochemical.
DC37252	Ampyrone	Ampyrone is a metabolite of AMINOPYRINE with analgesic and anti-inflammatory properties. It is used as a reagent for biochemical reactions producing peroxides or phenols. Ampyrone stimulates LIVER MICROSOMES and is also used to measure extracellular water.
DC37245	Piperonyl butoxide	Piperonyl butoxide (PBO) is an organic compound used as a component of pesticide formulations. It is a waxy white solid. It is a synergist. That is, despite having no pesticidal activity of its own, it enhances the potency of certain pesticides such as carbamates, pyrethrins, pyrethroids, and rotenone.[1] It is a semisynthetic derivative of safrole.
DC34632	MDL800	MDL-800 is a first-in-class cellularly active SIRT6 allosteric activator.
