Description:	Birinapant, a bivalent Smac mimetic, is a potent antagonist for XIAP and cIAP1 with Kds of 45 nM and less than 1 nM, respectively.
In Vivo:	Birinapant can inhibit tumor growth in melanoma xenotransplantation models. Staining for activated caspase-3 in biopsies of the same tumors show a modest increase in apoptotic cells in the birinapant treated animals[2]. Birinapant (15 mg/kg, i.p.) induces apoptosis in HCT116 tumor-bearing mouse[3].
In Vitro:	Birinapant causes significant degradation of cIAP1 and 2. Birinapant + TRAIL-treated cells show increased levels of active caspase-8 and caspase-3, as well as PARP cleavage, over single agents within 4 h of treatment, indicative of apoptosis-mediated cell death. Birinapan significantly decreases the viability of SUM190 cells in a dose-dependent manner. Birinapant treatment in the XIAP knockdown cell line (SUM190 shXIAP) causes an overall reduction in viability at lower doses (30-300 nM)[1]. Birinapant causes apoptosis in the sensitive cells. Birinapant in conbination with TNF-α, causes PARP cleavage in 451Lu and WM1366 cell lines[2]. Birinapant induces time-course of caspase-3 activation in HCT116 human colon carcinoma and MDA-MB-231 human breast adenocarcinoma cells[3].

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.
