Description	5-Hydroxyoxindole has been identified as a urinary metabolite of indole, which is produced from tryptophane via the tryptophanase activity of gut bacteria [1]. 5-Hydroxyoxindole has lipid peroxidation inhibition activity and free radical DPPH scavenging
In vitro	5-Hydroxyoxindole was less potent MAO-A inhibitor (IC50 56.8 microM) than isatin (31.8 microM) and especially 5-hydroxyisatin (6.5 microM), but it was the only highly selective MAO-A inhibitor among the all compounds studied (IC50 MAO-A:IC50 MAO-B = 0.044) [1].
In vivo	In blood plasma, 5-hydroxyoxindole levels were quite stable [2]. The maximal 5-hydroxyoxindole concentration in plasma was: 5.4 nM (5-hydroxyoxindole molecular weight: 149) [2].

Molecular Weight	149.15
Formula	C8H7NO2
CAS No.	3416-18-0

Storage

Powder: -20°C for 3 years | In solvent: -80°C for 1 year

The dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.

See Example

An example of a dilution calculation using the Tocris dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
Enter 20 into the Volume (final) box and select the correct unit (milliliter)
Press calculate
The answer of 100 microliter (0.1 ml) appears in the Volume (start) box
