Isatin (also named 2,3-Indolinedione) is an endogenous MAO inhibitor. Isatin induces apoptosis of MCF-7 cells. Bcl-2 expression is decreased and the ratio of Bcl-2 to Bax is significantly decreased by isatin. The mitochondrial transmembrane potential is markedly decreased and the release of cytochrome c into the cytosol is elevated following treatment with isatin. At the same time, caspase-9 and -3 are stimulated, followed by the degradation of ICAD, a caspase-3 substrate.
ln Vitro |
Isatin (1–400 μM) causes dose- and time-dependent cell death in dopaminergic SH-SY5Y cells. A continuum of necrosis, apoptosis, and survival led to this death[2].

ln Vivo |
Isatin, at a single dose of 80 mg/kg, acts quickly on the hypothalamic serotonergic system. While it did not significantly change 5-HIAA concentrations, isatin dramatically raises 5-HT concentrations in the cortex and hypothalamus[3].

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.75 mg/mL (18.69 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 27.5 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.  (Please use freshly prepared in vivo formulations for optimal results.) |

1 mM | 6.7967 mL | 33.9836 mL | 67.9671 mL | |
5 mM | 1.3593 mL | 6.7967 mL | 13.5934 mL | |
10 mM | 0.6797 mL | 3.3984 mL | 6.7967 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
