Description:	AS-604850 is a potent, selective and ATP-competitive PI3Kγ inhibitor with an IC50 value of 0.25 μM and a Ki value of 0.18 μM. AS-604850 shows isoform selective inhibitor of PI3Kγ with over 30-fold selectivity for PI3Kδ and β, and 18-fold selectivity over PI3Kα, respectively[1].
In Vivo:	AS-604850 (10-100 mg/kg; oral administration; for 4.5 or 4.25 hours; Balb/C or C3H mice) treatment reduces RANTES-induced peritoneal neutrophil recruitment with an ED50 value of 42.4 mg/kg. In the thioglycollate-induced peritonitis model, oral administration of 10 mg/kg AS-604850 results in a 31% reduction of neutrophil recruitment[1]. Animal Model: Balb/C or C3H mice with human recombinant RANTES or thioglycollate[1] Dosage: 10 mg/kg, 30 mg/kg or 100 mg/kg Administration: Oral administration; for 4.5 or 4.25 hours Result: Reduced RANTES-induced peritoneal neutrophil recruitment with an ED50 value of 42.4 mg/kg. In the thioglycollate-induced peritonitis model, resulted in a 31% reduction of neutrophil recruitment.
In Vitro:	AS-604850 inhibits C5a-mediated PKB phosphorylation with an IC50 of 10 μM in RAW264 mouse macrophages[1]. AS-604850 blocks PKB phosphorylation induced by MCP-1 and has little or no effect after stimulation with CSF-1 in in primary monocytes from Pik3cg+/+ or Pik3cg–/– mice[1]. AS-604850 (0-30 μM; 15 minutes; primary monocytes from Pik3cg+/+ mice) treatment inhibits MCP-1-mediated phosphorylation of PKB and its downstream substrates GSK3α andβ in a concentration-dependent manner. MCP-1-induced phosphorylation of p44/42 ERK (ERK1/2) MAPKs is also reduced, in a concentration dependent manner in primary monocytes from Pik3cg+/+ mice[1]. Western Blot Analysis[1] Cell Line: Primary monocytes from Pik3cg+/+ mice Concentration: 0 μM, 1 μM, 3 μM, 10 μM, 30 μM Incubation Time: 15 minutes Result: Inhibited MCP-1-mediated phosphorylation of PKB and its downstream substrates GSK3α andβ in a concentration-dependent manner. MCP-1-induced phosphorylation of p44/42 ERK (ERK1/2) MAPKs was also reduced, in a concentrationdependent manner in primary monocytes from Pik3cg+/+ mice.

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.
