Common NameQuebrachitol
DescriptionQuebrachitol or L-Quebrachitol or QCT, belongs to the class of organic compounds known as cyclohexanols. Cyclohexanols are compounds containing an alcohol group attached to a cyclohexane ring. Quebrachitol can also be classified as a cyclitol (a cyclic polyol). L-Quebrachitol is an optically active, hydrophilic, neutral molecule that is very water soluble. It exists as a white powder. It was first isolated in 1887 from the bark of Aspidosperma quebracho (a South American rubber tree species), from whence it received its name. Quebrachitol along with sucrose is one of the main sugars in the latex of rubber trees. Quebrachitol is a natural product that is found in a number of plants and plant foods, with the highest concentration being found in sea-buckthorn berries. L-Quebrachitol has also been detected, but not quantified in litchi, mugworts and in Cannabis sativa (PMID: 6991645 ). It shows a sweetening property half of that of sucrose but induces colic or diarrhea at concentration used to render the food palatable. Quebrachito has been shown to have gastroprotective effects against acute gastric lesions caused by NSAIDs (PMID: 28132388 ). It also acts as a platelet activating factor (PAF) inhibitor and binds to the platelet activating factor receptor (PAFR) at micromolar concentrations (PMID: 21060292 ). Quebrachito also appears to bind to a number of other proteins or protein targets including the IP3 receptor, β-glucosidase, PAFR, COX2, nitric oxide synthase, and K+ATP channels (PMID: 28132388 ).

Gene Name:
NOS2
Uniprot ID:
P35228
Molecular weight:
131116.3
General function:
Involved in inward rectifier potassium channel activity
Specific function:
In the kidney, probably plays a major role in potassium homeostasis. Inward rectifier potassium channels are characterized by a greater tendency to allow potassium to flow into the cell rather than out of it. Their voltage dependence is regulated by the concentration of extracellular potassium; as external potassium is raised, the voltage range of the channel opening shifts to more positive voltages. The inward rectification is mainly due to the blockage of outward current by internal magnesium. This channel is activated by internal ATP and can be blocked by external barium
