Based on 1 publication(s) in Google Scholar
GW779439X is a pyrazolopyridazine identified in an inhibitor of the S. aureus PASTA kinase Stk1. GW779439X potentiates the activity of β-lactam antibiotics against various MRSA and MSSA isolates, some even crossing the breakpoint from resistant to sensitive. GW779439X is an AURKA inhibitor and induces apoptosis by the caspases 3/7 pathway. MRSA:methicillin-resistant S. aureus; MSSA: methicillin-sensitive S. aureus

GW779439X (2 μM) biochemically inhibits Stk1. GW779439X (5 μM) potentiates ceftaroline activity against a ceftaroline-resistant MRSA strain. GW779439X is able to potentiate the activity of oxacillin against various S. aureus isolates, including both MRSA and MSSA isolates, but the potentiation is clearly strongest in PBP2A-containing strains[1].
GW779439X has growth inhibition effects on the AGP-01 cell line (IC50= 0.57 μM). GW779439X (1μM) significantly blockS the cell cycle at the G0/G1 phase and sub-G1 phase. GW779439X (1μM; 72 hours; AGP-01 cells) significantly decreases expression levels of genes involved in proliferation progression (c-MYC, NRAS, and CDC25A) and increases expression levels of genes involved in cell cycle blocking (CDKN1A and TP53)[2.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 3.33 mg/mL (7.33 mM); Clear solution

Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 3.33 mg/mL (7.33 mM); Clear solution
