7-Hydroxymitragynine (7-OH) is a terpenoid indole alkaloid from the plant Mitragyna speciosa, commonly known as kratom. [2] It was first described in 1994 [3] and is a human metabolite metabolized from mitragynine present in the Mitragyna speciosa, commonly known as kratom. 7-OH binds to opioid receptors like mitragynine, but research suggests that 7-OH binds with greater efficacy.
[32] [11] [9] The alkaloids mitragynine and 7-hydroxymitragynine are responsible for many of the complex effects of kratom, [11] [9] but other alkaloids may also contribute synergistically. [32] The effects of both mitragynine and 7-HMG remain disputed despite substantial study. Both are partial agonists of the μ-opioid receptor.
In Thai varieties of kratom, mitragynine is the most abundant component (up to 66% of total alkaloids), while 7-hydroxymitragynine (7-OH) is a minor constituent (up to 2% of total alkaloid content). In Malaysian kratom varieties, mitragynine is present at lower concentration (12% of total alkaloids). [ 5 ]
Mitragynine pseudoindoxyl is a rearrangement product of 7-hydroxymitragynine, an active metabolite of mitragynine. [ 1 ] Mitragynine pseudoindoxyl can be produced in the blood as a metabolite of 7-hydroxymitragynine.
Acute use (1–3 days) yields a potency about 1.5× stronger than that of morphine and chronic use (7 days+) yields a potency about 2.5 to 5× that of morphine. Similarly, the effect of tramadol increases after consecutive dosing due to the accumulation of its active metabolite and an increase of the oral bioavailability in chronic use.
KCNQ genes encode family members of the Kv7 potassium channel family. These include K v 7.1 - KvLQT1, K v 7.2 , K v 7.3 , K v 7.4 , and K v 7.5 . Four of these (KCNQ2-5) are expressed in the nervous system. They constitute a group of low-threshold voltage-gated K + channels originally termed the ‘M-channel’ (see M-current).
On the other hand, purinergic receptor activation can also lead to the opening of the channel, via a positive feedback loop. [4] In addition, P2Y receptors activate inositol trisphosphate , which leads to a transient increase in intracellular calcium , and opens both connexin and pannexin channels, therefore contributing to the propagation of ...
The functional expression of Hv1 in phagocytes has been well characterized in mammals, and recently in zebrafish, [6] suggesting its important roles in the immune cells of mammals and non-mammalian vertebrates. A group of small molecule inhibitors of the Hv1 channel are shown as chemotherapeutics and anti-inflammatory agents. [7]
