CU-CPT22

Catalog No. T15020Cas No. 1416324-85-0

CU-CPT22 is the first probe for the complex between toll-like receptors TLR1 and TLR2. CU-CPT22 binds at the interface of TLR1 and TLR2 (IC50 = 0.58 μM). It competes with the synthetic triacylated lipoprotein (Pam3CSK4) binding to TLR1/2 (Ki: 0.41 μM).

Description
CU-CPT22 is the first probe for the complex between toll-like receptors TLR1 and TLR2. CU-CPT22 binds at the interface of TLR1 and TLR2 (IC50 = 0.58 μM). It competes with the synthetic triacylated lipoprotein (Pam3CSK4) binding to TLR1/2 (Ki: 0.41 μM).

In vitro
A novel compound (CU-CPT22) that can compete with the synthetic triacylated lipoprotein (Pam3CSK4) binding to TLR1/2 with high inhibitory activity and specificity.CU-CPT22 is a toll-like inhibitor of receptor 1 and 2 (TLR1/2) ( IC50: 0.58±0.09 μM).?CU-CPT22 is found to have no significant cytotoxicity at various concentrations up to 100 μM in RAW 264.7 cells.?It is showed that CU-CPT22 is able to compete with Pam3CSK4 for binding to TLR1/2 (Ki: 0.41±0.07 μM).?Which is consistent with its potency observed in the whole cell assay.?Increasing the concentration of CU-CPT22 to 6 μM decreases the anisotropy to background levels.?It is found that CU-CPT22 inhibits TLR1/2 signaling without affecting other TLRs, showing it is highly selective in intact cells.??The result shows that CU-CPT22 can inhibit about 60% of TNF-αand 95% of IL-1β at 8 μM[1].

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
