Description:

NSC 617145 is a selective werner syndrome helicase (WRN) helicase inhibitor with an IC50 value of 230 nM. NSC 617145 inhibits WRN ATPase, and induces double-strand breaks (DSB) and chromosomal abnormalities. NSC 617145 shows selective for WRN over BLM, FANCJ, ChlR1, RecQ, and UvrD helicases[1].

In Vitro:

NSC 617145 (0.75-3 μM; 24-72 hours) shows maximal inhibition of proliferation (98%) at the lowest concentration in a WRN-specific manner in HeLa cells[1]. NSC 617145 (0.75 μM; 6 hours) induces WRN binding to chromatin and proteasomal degradation[1]. In FA-D2-/- cells, NSC 617145 (0.125 μM) acts synergistically with very low concentrations of Mitomycin C to inhibit proliferation in a WRN-dependent manner and induce double-strand breaks (DSB) and chromosomal abnormalities. NSC 617145 exposure results in enhanced accumulation of DNA-PKcs pS2056 foci and Rad51 foci in Mitomycin C-treated FA-deficient cells, suggesting that WRN helicase inhibition prevents processing of Rad51-mediated recombination products and activates NHEJ[1]. NSC 617145, induces cell cycle arrest and apoptosis in human T-cell leukemia virus type 1 (HTLV-1)-transformed adult T-cell leukemia cells[2]. Cell Viability Assay[1] Cell Line: HeLa cells Concentration: 0.75 μM, 1 μM, 1.5 μM, 2 μM, 3 μM Incubation Time: 24 hours, 48 hours, 72 hours Result: Inhibited cell proliferation in a WRN-specific manner. Western Blot Analysis[1] Cell Line: HeLa cells Concentration: 0.75 μM Incubation Time: 6 hours Result: Caused WRN to become degraded by a proteasome-mediated pathway.

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.
