Bioactive Small Molecules

Application

Prazosin hydrochloride has been used:

to block the α1adrenergic receptors that mediate sympathetic vasoconstriction in mice
as an α1-adrenoceptor blocker,administered intragastrically in rats
as a vasodilator,administered together with inuslin into the left ventricle of mice for the assessment of its effects on renal functions

Biochem/physiol Actions

Peripheral α1-adrenoceptor antagonist; vasodilator. Prazosin can be used to treat chronic posttraumatic stress disorder (PTSD). It plays a role in reducing blood pressure by relaxing blood vessels, hence used in the treatment of high blood pressure.

Disclaimer

Hygroscopic; light sensitive.

Initial orthostatic hypotension and cerebral blood flow regulation: effect of α1-adrenoreceptor activity.

Nia C S Lewis et al.

American journal of physiology. Regulatory, integrative and comparative physiology, 304(2), R147-R154 (2012-11-24)

We examined the hypothesis that α(1)-adrenergic blockade would lead to an inability to correct initial orthostatic hypotension (IOH) and cerebral hypoperfusion, leading to symptoms of presyncope. Twelve normotensive humans (aged 25 ± 1 yr; means ± SE) attempted to complete

A trial of prazosin for combat trauma PTSD with nightmares in active-duty soldiers returned from Iraq and Afghanistan.

Murray A Raskind et al.

The American journal of psychiatry, 170(9), 1003-1010 (2013-07-13)

The authors conducted a 15-week randomized controlled trial of the alpha-1 adrenoreceptor antagonist prazosin for combat trauma nightmares, sleep quality, global function, and overall symptoms in active-duty soldiers with posttraumatic stress disorder (PTSD) returned from combat deployments to Iraq and

(11)C-CUMI-101, a PET radioligand, behaves as a serotonin 1A receptor antagonist and also binds to α(1) adrenoceptors in brain.

Stal Saurav Shrestha et al.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 55(1), 141-146 (2014-01-05)

The PET radioligand (11)C-CUMI-101 was previously suggested as a putative agonist radioligand for the serotonin 1A (5-hydroxytryptamine 1A [5-HT1A]) receptor in recombinant cells expressing human 5-HT1A receptor. However, a recent study showed that CUMI-101 behaved as a potent 5-HT1A receptor
