Description:

Sofosbuvir (PSI-7977) is an HCV RNA replication inhibitor with an EC50 of 92 nM.

In Vitro:

When cathepsin A (CatA) is incubated with PSI-7977 or Sofosbuvir (PSI-7977) for 150 min, ~18-fold more PSI-352707 is formed when Sofosbuvir (PSI-7977) is the substrate compared with PSI-7976. Moreover, the catalytic efficiency for Sofosbuvir (PSI-7977) with CatA is ~30-fold higher than that for PSI-7976[1]. The genotype coverage of Sofosbuvir (PSI-7977) by using GT 1b (Con1)-, 1a (H77)-, and 2a (JFH-1)-derived replicons and GT 1b chimeric replicons containing the NS5B region from the J6 GT 2a isolate and from GT 2b and GT 3a patient isolates is evaluated, Sofosbuvir (PSI-7977) inhibits the replication of these replicons with similar EC50s (between 16 and 48 nM), and is especially active against the chimeric replicon containing the J6 NS5B (EC50=4.7 nM). Sofosbuvir (PSI-7977) inhibits clone A (GT 1b) wild-type and S282T replicons with EC90 values of 0.42 and 7.8 μM, respectively[2]. In the clone A replicon assay, Sofosbuvir (PSI-7977) produces anti-HCV activity with EC90 values 0.42 μM[3].

Cat. No.	Product name	Field of application
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.

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.
