65:. The receptor is known to consist of two hydrogen bond donors, where the C3 and 17β-side chain of the ligands connect, as well as three hydrophobic groups distributed over the steroidal structure. The best receptor inhibitors comply with these factors. Azasteroids are a type of steroid derivatives which have nitrogen atoms replaced at various positions for one of the carbon atoms in the steroid ring system. Two 4-azasteroids, finasteride and dutasteride are marketed as 5-ARIs. Finasteride (Proscar or Propecia) was the first steroidal 5α-reductase inhibitor approved by the U.S.

Benzo(f)quinolonone are also tricyclic compounds, but derivatives of the 4-azasteroid structure.

Benzo(c)quinolizinones are tricyclic derivatives of 10-azasteroids. The D-ring has been removed and the C-ring substituted for an aromatic one. The first compounds developed were selective 5-alpha reductase type 1 inhibitors, but the most potent one inhibits both type 1 and 2. The fluorine atom is an

Many steroidal 5-ARIs have been researched but only 3 are marketed. Two of them are 4-azasteroids and will be covered here. As mentioned above, the third one, epristeride is only marketed in China and will not be covered here. The basic SAR of 4-azasteroids is shown below. For competitive inhibiting

Dutasteride (Avodart) was the second steroidal 5α-reductase approved after finasteride. It is a competitive inhibitor of all three 5α-reductase isoenzymes and it inhibits types 1 and 2 better than finasteride, leading to it causing further reduction in DHT, with >90% recuded DHT levels following
162:
Dutasteride, however, is a so-called dual inhibitor with both 5α-R1 and 5α-R2 inhibition. IC50 for 5α-R1 is 7 nM but 6 nM for 5α-R2. As mentioned above, it reduces DHT > 90% overall, or precisely 94.7% and for intraprostatic DHT the reduction is 97-99%. Dutasteride has also been found to inhibit

The 5α-reductase isozymes possess a similar steroidal catalytic site. The only available information about the 5α-reductase isozymes is their primary sequence estimated from c-DNAs and that affects the design of the novel inhibitors. The crystal structure of the 5α-reductase isozymes is not known
191:
The common factor in nonsteroidal 5-ARI discovery is that the first compounds were all selective inhibitors to 5α-reductase type 1 only, but were then developed in order to get dual inhibition on both type 1 and 2, since inhibition of the type 2 isozyme is a more important factor in treating the

Piperidones are also 4-azasteroid derivatives but both B- and D-ring have been removed. The original compounds designed were type 1 selective, especially the ones containing a chlorine atom connected to the aromatic ring. By inserting a styryl group to the piperidones type 2 inhibitory activity

Various pharmaceutical and academic groups have conducted the synthesis of nonsteroidal compounds that inhibit human 5α-reductases due to the unwanted hormonal side effects of steroidal compounds. Nonsteroidal inhibitors can be categorized due to their structure. Many have been obtained from

designed to resemble steroidal carboxylic acids such as episteride. As with the other nonsteroidal inhibitors, they have been designed by removing steroid ring systems. As with the piperidones, addition of a styryl group provides good dual inhibition on isozyme 1 and 2, but the nonsteroidal

Finasteride is considered similar to the transition state of reduced testosterone and is thus a slow-offset, irreversible inhibitor. The similarity to the transition state is a formation of an enzyme-NADP-dihydrofinasteride adduct by rearrangement on the A-ring of the compound.
158:
Finasteride mainly inhibits the 5α-R2 (IC50=69 nM) and 5α-R3 (IC50=17.4 nM) with little inhibition of 5α-R1 (IC50=360 nM). As mentioned above, finasteride reduces prostatic DHT levels on a 70-90% range but the detailed reduction of DHT is 70.8% and 85% of intraprostatic DHT.
183:. There is no detailed data about the cause of hepatotoxicity in 4-MA regarding SAR, but a conclusion may be drawn that the R2 group is the cause as there are other 4-azasteroid compounds containing the same R1 group as 4-MA, or CH3, without showing hepatotoxicity.

functions there are two functions considered crucial, 4-en-3-one function and a lipophilic 17β-side chain with one or more oxygen atoms. The main problems for 4-azasteroids is the rapid conversion into inactive 4,5-dihydro form, which is done by the enzyme.

because the nature of the 5α-reductase enzyme is so unstable during purification. The first 5-ARIs were designed by modifying the structure of natural substrates, including the substitution of one carbon atom of the rings of the steroids by a

Finasteride is an unsaturated analogue of another 4-azasteroid, or 4-MA. 4-MA is known to have dual inhibiting features with good inhibition on 5α-R1 (IC50=1.7 nM) and 5α-R2 (IC50=1.9 nM). However, 4-MA was never marketed as it showed
