Product Introduction

YKL-05-099 is an inhibitor of the salt-inducible kinase(SIK1 and SIK3 ; IC50s: 10 and 30 nM, respectively). It has a slightly less potent SIK2-inhibitory (IC50:40 nM).
In vitro
YKL-05-099 inhibits the production of the inflammatory cytokines TNFα, IL-6 and IL-12p40, and only modestly enhances IL-1β release in BMDCs stimulated with the yeast cell wall extract Zymosan A. YKL-05-099 has slightly less potent SIK2-inhibitory (IC50=40 nM) and IL-10-enhancing activities (EC50=460 nM). YKL-05-099 binds to SIK1 and SIK3 (IC50s: 10 and 30 nM, respectively, in a competitive binding assay). Preincubating bone marrow-derived macrophages with YKL-05-099 decreases LPS stimulated phosphorylation of HDAC5 at the SIK-specific phosphorylation site Ser259 [1].
In vivo
YKL-05-099 exhibits high solubility (PBS solubility=428 μM) and is predominantly in an unbound state in mouse plasma, displaying non-toxic characteristics at concentrations below 10 μM. This compound is metabolically stable, showing more than 2 hours of stability in mouse liver microsomes. Functionally, YKL-05-099 effectively modulates immune response by reducing TNFα levels in a dose-dependent manner, starting at 5 mg/Kg, and significantly enhancing IL-10 secretion at a 20 mg/Kg dose, achieving a more than two-fold increase. Furthermore, it inhibits phosphorylation of HDAC5 at the SIK-regulated site (Ser259) in a dose-responsive manner, with notable reduction starting at 5 mg/Kg and becoming undetectable by immunoblotting from the 20 mg/Kg dose onwards [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
