Seconeolitsine
Based on 1 Customer Validation
Seconeolitsine, an antibiotic, and is an inhibitor of targeting topoisomerase I (TopA). Seconeolitsine also is a new antimicrobial agent that can inhibit S. pneumoniae growth. Seconeolitsine can inhibit TopA relaxation activity with an IC50 value of 17 μM. Seconeolitsine can be used for the research of S. pneumoniae infections resistant to other antibiotics.

Biological Activity
|
Topoisomerase I 17 μM (IC50) |
Seconeolitsine (compounds 17) inhibits TopA relaxation activity in a concentration-dependent manner, with an IC50 value of 17 μM and the inhibition of TopA is enhanced by preincubation of the enzyme with the alkaloid[1].
Seconeolitsine shows great inhibition of S.pneumoniae growth with MIC50 values of 16 μM for R6, ATCC6303, CipS8, CipS9, CipR20, CipR16, CipR8, CipR45 and CipR5. And shows great inhibition of S. pneumoniae growth with MIC50 values of 8 μM for CipR42, CipR68 and CipR15[1].
Seconeolitsine has activation at low concentrations and partial inhibition at 50 μM, a concentration at which the pneumococcal TopA showed full inhibition, but not inhibits Human TOPO1[1].
Seconeolitsine (0.25×-1×MIC) affects cell growth and division in a concentration-dependent manner[1].
Seconeolitsine (30 and 100 μM), is not affected neutrophil apoptosis and human cell viability[1].

* In solvent : -80°C, 6 months; -20°C, 1 month (stored under nitrogen)
Solvent & Solubility
DMSO : 50 mg/mL (154.64 mM; ultrasonic and warming and heat to 80°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (stored under nitrogen). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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: 2.5 mg/mL (7.73 mM); Clear solution; Need ultrasonic
This protocol yields a clear solution of 2.5 mg/mL.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
