Salicylhydroxamic acid

Description

Salicylhydroxamic acid (SHAM; synonym: 2-Hydroxybenzohydroxamic acid N,2-Dihydroxybenzamide) is an inhibitor of the alternative oxidase (AOX). When AOX is blocked by SHAM, electrons are forced through the CIII-cytochrome c oxidase pathway, allowing observation of the operation of the CIII-CIV pathway without AOX activity.

Abbreviation: SHAM

Reference: Parrino_2000_J_Exp_Biol

Application in HRR

SHAM: Salicylhydroxamic acid (99%; HOC₆H₄CONHOH); Sigma S 607, 5 g, store at RT; M = 153.14 g·mol^-1.

SHAM is reported to be easily soluble in EtOH. So EtOH could be considered as a solvent, too. However, in Oroboros-lab SHAM in EtOH has not been tested yet.

Caution: Irritant!

Preparation of 250 mM stock solution (dissolved in DMSO):

Weigh 76.57 mg of SHAM.
Dissolve in 1950 µL of DMSO.
Divide into 0.2 mL portions
Store at -20 °C.
