Butofilolol (trade name Cafide) is a beta-blocker drug for the treatment of essential hypertension (high blood pressure). [1] [2] It is not known to be marketed anywhere.

It is an example of a butyrophenone.

Synthesis

Butofilolol synthesis.svg

The Fries rearrangement of the ester formed by 4-fluorophenol (1) [3] and butryryl chloride (2) gives 5'-fluoro-2'-hydroxybutyrophenone (3). Treatment with epichlorohydrin in the presence of base leads to 1-[5-fluoro-2-(oxiranylmethoxy)phenyl]butan-1-one (4). Lastly, reaction with tert-butylamine gives butofilolol. [4] [5]

Nomifensine (Merital, Alival) is a norepinephrine-dopamine reuptake inhibitor, i.e. a drug that increases the amount of synaptic norepinephrine and dopamine available to receptors by blocking the dopamine and norepinephrine reuptake transporters. This is a mechanism of action shared by some recreational drugs like cocaine and the medication tametraline (see DRI). Research showed that the (S)-isomer is responsible for activity.

Fenobam is an imidazole derivative developed by McNeil Laboratories in the late 1970s as a novel anxiolytic drug with an at-the-time-unidentified molecular target in the brain. Subsequently, it was determined that fenobam acts as a potent and selective negative allosteric modulator of the metabotropic glutamate receptor subtype mGluR5, and it has been used as a lead compound for the development of a range of newer mGluR5 antagonists.

5-HT<sub>7</sub> receptor Protein-coding gene in the species Homo sapiens

The 5-HT7 receptor is a member of the GPCR superfamily of cell surface receptors and is activated by the neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). The 5-HT7 receptor is coupled to Gs (stimulates the production of the intracellular signaling molecule cAMP) and is expressed in a variety of human tissues, particularly in the brain, the gastrointestinal tract, and in various blood vessels. This receptor has been a drug development target for the treatment of several clinical disorders. The 5-HT7 receptor is encoded by the HTR7 gene, which in humans is transcribed into 3 different splice variants.

WAY-100635 is a piperazine drug and research chemical widely used in scientific studies. It was originally believed to act as a selective 5-HT1A receptor antagonist, but subsequent research showed that it also acts as potent full agonist at the D4 receptor. It is sometimes referred to as a silent antagonist at the former receptor. It is closely related to WAY-100135.

Fluperlapine, also known as fluoroperlapine, is a morphanthridine (11H-dibenzo[b,e]azepine) atypical antipsychotic with additional antidepressant and sedative effects. It was first synthesized in 1979, and then subsequently studied in animals and humans in 1984 and beyond, but despite demonstrating efficacy in the treatment of a variety of medical conditions including schizophrenia, psychosis associated with Parkinson's disease, depressive symptoms, and dystonia, it was never marketed. This was perhaps due to its capacity for producing potentially life-threatening agranulocytosis, similarly to clozapine, which it closely resembles both structurally and pharmacologically.

Epiestriol, or epioestriol, also known as 16β-epiestriol or simply 16-epiestriol as well as 16β-hydroxy-17β-estradiol, is a minor and weak endogenous estrogen, and the 16β-epimer of estriol. Epiestriol is used clinically in the treatment of acne. In addition to its estrogenic actions, epiestriol has been found to possess significant anti-inflammatory properties without glycogenic activity or immunosuppressive effects, an interesting finding that is in contrast to conventional anti-inflammatory steroids like hydrocortisone.

5α-Dihydroethisterone is an active metabolite of the formerly clinically used but now-discontinued progestin ethisterone and the experimental and never-marketed hormonal antineoplastic agent ethynylandrostanediol (HE-3235). Its formation from its parent drugs is catalyzed by 5α-reductase in tissues that express the enzyme in high amounts like the liver, skin, hair follicles, and prostate gland. 5α-DHET has significant affinity for steroid hormone receptors and may contribute importantly to the activities of its parent drugs.
