I was doing a little reading about the effects that harmala alkaloids have on the human body, primarily harmine, harmaline and harmalol. Looking at the cardiovascular effects of the three compounds, they all seem to produce vasorelaxation with rank order of relaxation potency, harmine > harmaline > harmalol. The primary mechanism for this being increased release of nitrous oxide from endothelial cells that line the internal surface of blood vessels. Another mechanism being attributed to their antiadrenergic interaction with the alpha 1-adrenergic receptors found on the vascular smooth muscle that form the blood vessel walls, controlling blood flow via contraction and relaxation. I'm assuming that the three harmala alkaloids function as either a antagonist or inverse agonist in this case? Anyway it is by these mechanisms are harmine, harmaline and harmalol able to decrease systemic arterial blood pressure and total peripheral resistance. In addittion to these effects there are also:
- Bradycardia.
- Increased cardiac contractile force and therefore pulse pressure.
- Increased velocity of aortic blood flow.
- Angiogenic inhibitory effects.
Looking at all these various cardiovascular effects and the mechanisms behind them it would seem that at first glance the harmala alkaloids could be beneficial in treating conditions such as high blood pressure and preventing CVD in those who are at high risk. However these are often always chronic medical conditions and I'm not sure if chronically dosing harmalas for a long period of time would be such a good idea. On the other hand using harmalas to treat acute high blood pressure during stressors like exercise for example might actually be a feasible idea IMO. Just my take on things, do with it what you want!
P.S. I'm not too sure how increased pulse pressure and peak aortic flow contribute to hypertension.
