Description:	ASP5878 is an oral active and selective inhibitor of the fibroblast growth factor receptor (FGFR), with an IC50 of 3.5 nM for fibroblast growth factor receptor 4 kinase activity. ASP5878 has potential antineoplastic activity[1].
In Vivo:	ASP5878 (3 mg/kg, orally, once daily) shows antitumor activity in a Hep3B2.1-7 subcutaneous xenograft and HCC orthotopic xenograft mouse model[1]. ASP5878 induces shrinkage of FGF19-expressing HCC xenograft model[1]. Animal Model: Four-week-old male nude mice (CAnN.Cg-Foxn1nu/CrlCrlj [nu/nu]) (Hep3B2.1-7 cells inoculated subcutaneously)[1]. Dosage: 3 mg/kg. Administration: Orally once daily from days 14 to 52. Result: Induced tumor regression by 9% and 88% at 1 and 3 mg/kg, respectively, without affecting the body weight for 14 days. Induced the suppression of FGFR4 phosphorylation, mobility shift of FRS2, and suppression of ERK phosphorylation. Animal Model: HCC orthotopic xenograft model (mouse)[1]. Dosage: 3 mg/kg. Administration: Orally once daily for 24 days. Result: Exhibited a lower tumor burden than vehicle- and sorafenibtreated mice. Induced sustained tumor regression without tumor regrowth.
In Vitro:	ASP5878 shows potent antiproliferative activity in most human HCC cell lines[1]. ASP5878 inhibits FGFR4 phosphorylation in a concentration-dependent manner. ASP5878 treatment results in the suppression of phosphorylation, mobility shift of FRS2, and suppression of ERK phosphorylation[1]. Cell Viability Assay[1] Cell Line: Human HCC cell lines. Concentration: 0-10000 nM. Incubation Time: 5 days. Result: HuH-7, Hep3B2.1-7, and JHH-7 cell lines exhibited potent sensitivity to ASP5878, with IC50 values of 27, 8.5, and 21 nmol/L, respectively. The growth inhibition rate of HLF was 64% and those of other ASP5878-sensitive cell lines were higher than 95% at 1000 nM.

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. .
DC47877	tri-GalNAc-COOH (acetylation)	tri-GalNAc-COOH acetylation is the acetylated and modified form of tri-GalNAc-COOH. tri-GalNAc-COOH acetylation can be used for the synthesis of LYTAC.
DC46965	Tri-GalNAc-COOH	tri-GalNAc-COOH is an asialoglycoprotein receptor (ASGPR) ligand that can be used for LYsosome TArgeting Chimera (LYTAC) research.
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.
