  2. PROTACs NAMPT
  3. Nampt degrader-2

Nampt degrader-2 is a fluorescent PROTAC, which efficiently degrades NAMPT with an IC50 of 41.9 nM. Nampt degrader-2 binds to NAMPT and VHL to form a ternary complex and subsequently induced NAMPT degradation via ubiquitin-proteasome system (UPS). Nampt degrader-2 leads to significant reduction of NAD+ and exerts potent antitumor activities.

Description

Nampt degrader-2 is a fluorescent PROTAC, which efficiently degrades NAMPT with an IC50 of 41.9 nM. Nampt degrader-2 binds to NAMPT and VHL to form a ternary complex and subsequently induced NAMPT degradation via ubiquitin-proteasome system (UPS). Nampt degrader-2 leads to significant reduction of NAD+ and exerts potent antitumor activities[1].

NAMPT

41.9 nM (IC50)

In Vitro

Nampt degrader-2 (Compound B4; 30 nM; 24 h) is able to degrade NAMPT with a DC50 value of 8.4 nM. Nampt degrader-2 enables the visualization of degradation in A2780 cells[1].
Nampt degrader-2 (Compound B4) shows the best antitumor activity in suppression of the proliferation in A2780 cells (IC50 = 12.1 nM)[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Western Blot Analysis[1]

Cell Line: A2780 cells
Concentration: 30 nM
Incubation Time: 24 h
Result: Were able to degrade NAMPT in A2780 cells at the concentration of 30 nM.
In Vivo

Nampt degrader-2 (Compound B4; 10-30 mg/kg; i.p; once a day; for 14 consecutive days) shows excellent antitumor effects in a dose-dependent manner. And Nampt degrader-2 significantly decreases the NAMPT levels in the tumors[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: BALB/C nude female mice (4-5 weeks of age, 14-18 g) injected with A2780 cells[1]
Dosage: 10 mg/kg, 30 mg/kg
Administration: i.p; once a day; for 14 consecutive days
Result: Achieved excellent antitumor effects in a dose-dependent manner.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
