Fezolinetant, sold under the brand name Veozah among others, is a medication used for the treatment of hot flashes (vasomotor symptoms) due to menopause. [4] [10] It is a small-molecule, orally active, selective neurokinin-3 (NK 3) receptor antagonist which is under development by for the treatment of sex hormone-related disorders.
For many years, the structure was assigned, incorrectly, as having a "linear structure" (EC no. 228-767-9, CAS RN 6358-30-1) which differ in terms of the carbazole ring fusion. [3] Pigment violet 23 is prepared by condensation of an aniline with chloranil. [4] Synthetic route to dioxazine dyes such as pigment violet 23.

[5] There was no variation in DHT levels across the menstrual cycle in premenopausal women, which is in contrast to testosterone (which shows a peak at mid-cycle ). [ 5 ]
5α-Pregnan-17α-ol-3,20-dione is produced by 5α-reduction of 17-OHP. The reaction is catalyzed by SRD5A1 [14] and possibly, SRD5A2 enzymes. [7] While the role of the SRD5A1 enzyme in this reaction is well established, it is unclear whether SRD5A2 is also involved. [13]
