PROTAC SAMHD1 Degrader-1 is an orally active targeted SAMHD1 PROTAC degrader, with an IC50 of 6.3 μM against the dNTP hydrolase activity of SAMHD1. PROTAC SAMHD1 Degrader-1 binds to SAMHD1 inside cells and mediates its degradation, with low off-target effects. PROTAC SAMHD1 Degrader-1 inhibits the production of pro-inflammatory cytokines and interferes with the cascade amplification process of inflammatory responses. PROTAC SAMHD1 Degrader-1 delays the progression of pulmonary fibrosis and exerts protective effects on lung tissues. PROTAC SAMHD1 Degrader-1 can be used in pulmonary fibrosis-related research.

In Vitro

PROTAC SAMHD1 Degrader-1 (compound NP12) (0.15-10.0 μM; 6-48 h) induces dose- and time-dependent degradation of SAMHD1 in THP-1 cells, with a DC50 of 1.2 μM[1].
PROTAC SAMHD1 Degrader-1 (10 μM; 24 h pretreatment) increases the sensitivity of wild-type THP-1 cells to Ara-C, reducing the IC50 of Ara-C from 5.4 μM to 1.1 μM, which confirms that it inhibits SAMHD1 activity in cells[1].
PROTAC SAMHD1 Degrader-1 (1-10 μM; 1 h pretreatment) suppresses the production of LPS (HY-D1056)-induced proinflammatory cytokines (IL-1β, IL-6, TNF-α) in RAW264.7 macrophages in a concentration-dependent manner, and interferes with the transcription, translation and secretion of cytokines[1].

In Vivo

PROTAC SAMHD1 Degrader-1 (20-80 mg/kg; p.o.; once daily; for 14 consecutive days) induces dose-dependent degradation of SAMHD1 in mouse lung tissue, delays the progression of Bleomycin (HY-108345)-induced pulmonary fibrosis, alleviates lung tissue damage and collagen deposition, and reduces the levels of pro-inflammatory/pro-fibrotic cytokines[1].

Animal Model: C57BL/6 (male, 6-8 weeks old, 18-22 g, intratracheal bleomycin-induced pulmonary fibrosis)[1]
Dosage: 20 mg/kg; 40 mg/kg; 80 mg/kg
Administration: i.g.; daily; 14 days
Result: Showed gradual body weight recovery from day 9 onward.
Reduced bleomycin-induced lung tissue damage, including alleviated alveolar atrophy/collapse, bronchial wall thickening, and inflammatory cell infiltration.
Decreased collagen fiber deposition in a dose-dependent manner.
Significantly downregulated lung tissue expression of α-smooth muscle actin and fibronectin in a dose-dependent manner.
Reduced serum and bronchoalveolar lavage fluid levels of proinflammatory and profibrotic cytokines (IL-1β, IL-6, TGF-β1), with the 80 mg/kg dose showing the most pronounced effects.
Reduced lung tissue SAMHD1 protein levels to 80.7% (20 mg/kg), 58.3% (40 mg/kg), and 21.9% (80 mg/kg) of the control group, demonstrating dose-dependent degradation.

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.
