Seco-DUBA
Based on 1 Customer Validation
Seco-DUBA hydrochloride is a DNA-targeting cytotoxic agent. Seco-DUBA hydrochloride binds to the minor groove of A-T-rich DNA regions, alkylates the adenine N3 residue, and undergoes spontaneous spirocyclization to generate active DUBA (HY-160969). Seco-DUBA hydrochloride exerts cytotoxic activity against human cancer cells. The reduced hydrophobicity of Seco-DUBA hydrochloride supports the development of antibody-drug conjugates.

In Vitro
Seco-DUBA (SK-BR-3 cells; 0.0001 pM~0.01 nM; 144 hours) dose-dependent reduces cell viability and shows equally potent and efficacious as DUBA[1].
Seco-DUBA causes SK-BR-3 (IC50=0.09), SK-OV-3 (IC50=0.43), and SW620 (IC50=0.09) cells to exhibit highly sensitive[1].

In Vitro:
DMSO : 100 mg/mL (189.76 mM; ultrasonic and warming and heat to 60°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.

In Vivo:
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: 1 mg/mL (1.90 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 1 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (10.0 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 1 mg/mL (1.90 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 1 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

Protocol
-
Cell Cytotoxicity Assay
Cytotoxicity assays are usually based on the assessment of cell membrane damage, which can also be indirectly detected by measuring cell viability. Detection methods include MTT assay, CKK-8 assay, LDH assay and ATP assay, etc.
-
Cell Viability Determination by MTT Colorimetric Assay
The following protocol uses the MTT colorimetric assay as a classic literature-established method for assessing cell viability/metabolic activity in cultured mammalian cells. MTT[3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] is reduced by metabolically active cells to a colored formazan product; the amount of formazan is quantified spectrophotometrically and provides an indirect measure of metabolically active viable cells. Importantly, MTT reduction reflects cellular oxidoreductase/metabolic activity rather than an absolute direct count of living cells, so changes in cellular metabolism can alter the signal independently of cell number.
