Neurosteroids anxiety

The term “neurosteroid” (NS) was introduced by Baulieu in 1981 to name a steroid hormone, dehydroepiandrosterone sulfate (DHEAS), that was found at high levels in the brain long after gonadectomy and adrenalectomy, and shown later to be synthesized by the brain. The term “neuroactive steroid” (NAS) refers to steroids that, independent of their origin, are capable of modifying neural activities. NASs bind and modulate different types of membrane receptors. The γ-amino butyric acid (GABA) and Sigma receptor complexes have been the most extensively studied, while glycine chloride channels, nicotinic acetylcholine receptors, and voltage-activated calcium channels, although less explored, are also modulated by NASs. Within the glutamate receptor family, N -methyl-D-aspartate (NMDA) receptors, α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors and kainate receptors have been shown to be targets for NA and NAS modulation. Inside the neuron, Oxidized ring A reduced pregnanes, tetrahydroprogesterone (THP), and tetrahydrodeoxycorticosterone (THDOC) bind to the progesterone intracellular receptor (PR) and in this way can also regulate gene expression. Animal experimentation showed that cardinal symptoms of depression, anxiety, sleep disturbances, and memory dysfunctions are partly regulated by NAS. In turn, NAS and NS levels are modulated by psychotropic medications. NS levels, as well as NAS plasma concentrations, change in patients with depression syndromes, the levels return to normal baseline with recovery, but normalization is not necessary for successful therapy. Rather than with nosological syndromes and psychiatric disorders, NAS and NS steroid levels seem to correlate with specific symptoms. Hence, it will be profitable to search for and establish symptom-steroid relationships, as well as pharmacological and endogenous factors that can modulate NS biosynthesis and NAS formation, to be able to use these steroids in therapy.

The pharmacological actions of benzodiazepines at the GABA A receptor are similar to those of neurosteroids . Neuroactive steroids are positive allosteric modulators of the GABA A receptor, enhancing GABA function and in turn have effects on mood and other functions. Many benzodiazepines ( diazepam , medazepam , estazolam , temazepam , flunitrazepam and nitrazepam) potently inhibit the enzymes involved in the metabolism of neurosteroids. The tetrahydroxazole ring that cloxazolam and oxazolam have decreases the inhibitory potency of benzodiazepines on neurosteroids. Thus there could be subtle differences between cloxazolam and other benzodiazepines. [12] However, because the parent prodrugs of cloxazolam and oxazolam were tested rather than the active metabolites, this is purely speculative.

I know a lot depends on each individual, but any feedback would be greatly appreciated.

In the mid 1980s, the neuroactive steroids 3α,5α-tetrahydroprogesterone or allopregnanolone (3α,5α-THP) and 3α,5α- tetrahydrodeoxycorticosterone (3α,5α-THDOC) were shown to modulate neuronal excitability via their interaction with GABA A receptors. The steroids 3α,5α-THP and 3α,5α-THDOC were able to enhance the GABA-elicited Cl − current. [13] In addition, these steroids might enhance the binding of muscimol and benzodiazepines to GABA A receptors. [30] Structure- activity studies (SAR) showed that the 3alpha-OH group is essential for the anesthetic actions of these steroids, [31] they also have an optimally-placed hydrogen bond accepting group on the β face of the steroid at the C-17 position. The four steroid rings form a rigid framework for positioning these hydrogen groups in three-dimensional space. [32] Analogues 5 and 6 (Figure 10) are weak modulators of GABA A receptor function because the flexible side chains in these analogues do not have the conformations required for high biological activity.
