XL-3158

Customer Review

Based on 1 Customer Validation

XL-3158 is a selective and cross-species Cyclic GMP-AMP synthase (cGAS) inhibitor (IC₅₀: 11.1 μM for human cGAS, 2.19 μM for mouse cGAS). XL-3158 simultaneously occupy allosteric and orthosteric sites, stabilizing the activation loop in a closed, inactive conformation and thereby attenuating the cGAS-DNA interactions. XL-3158 inhibits cGAS by targeting phase separation. XL-3158 efficiently penetrates cells by inhibiting aggregate formation, effectively reducing the local concentration of cGAS within cells. XL-3158 can be used for the study of cGAS-dependent inflammatory diseases.

Description

All IKK Isoforms :

In Vitro

XL-3158 (Compound XL-3158) (20 μM, 4 h) blocks cGAS intracellular condensation with DNA by inhibiting cGAS phase separation in L929 cells^[1].

XL-3158 (10-40 μM, 4 h) specifically inhibits downstream signaling activation of the cGAS-STING pathway in THP-1 Dual cells^[1].

XL-3158 (10 μM, 4 h) selectively inhibits the DNA-triggered cGAS-dependent interferon pathway in THP-1 Dual cells^[1].

XL-3158 (0-20 μM, 24 h) has CC50 values of 77.55 μM against THP-1 cells and 56.79 μM against RAW-ISG cells^[1].

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

In Vivo

XL-3158 (Compound XL-3158) (25 mg/kg, i.g. twice administration) attenuates Cerulein (HY-A0190)-induced acute pancreatitis^[1].

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

Animal Model:

Dosage:

25mg/kg
Administration:

Intragastric gavage (i.g.), administration at 0 hour and 6 h after the first Cerulein injection.
Result:

Significantly reduced pancreatic pathological damage and the pancreas/body weight ratio, indicating that pancreatic edema was relieved.
Significantly reduced serum amylase and serum lipase activities.
Significantly reduced serum inflammatory factor levels.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
