Abstract
CYP17A1 is an enzyme that plays a major role in steroidogenesis and is critically involved in the biosynthesis of steroid hormones. Therefore, it remains an attractive target in several serious hormone-dependent cancer diseases, such as prostate cancer and breast cancer. The medicinal chemistry community has been committed to the discovery and development of CYP17A1 inhibitors for many years, particularly for the treatment of castration-resistant prostate cancer. The current Perspective reflects upon the discovery and evaluation of non-steroidal CYP17A1 inhibitors from a medicinal chemistry angle. Emphasis is placed on the structural aspects of the target, key learnings from the presented chemotypes, and design guidelines for future inhibitors.

Abstract
Photoredox catalysis has been developed to achieve room temperature oxidative C–H chlorination of aromatic compounds using NaCl as the chlorine source and Na2S2O8 as the oxidant.
Photoredox catalysis has been developed to achieve oxidative C–H chlorination of aromatic compounds using NaCl as the chlorine source and Na2S2O8 as the oxidant. The reactions occur at room temperature and exhibit exclusive selectivity for C(sp2)–H bonds over C(sp3)–H bonds. The method has been used for the chlorination of a diverse set of substrates, including the expedited synthesis of key intermediates to bioactive compounds and a drug.

Abstract
The cytochrome P450 enzyme, 17alpha-hydroxylase/17,20-lyase (P450(17alpha)), is a potential target in hormone-dependent cancers. We report the synthesis, biochemical evaluation and rationalisation of the inhibitory activity of a number of azole-based compounds as inhibitors of the two components of P450(17alpha), i.e., 17alpha-hydroxylase (17alpha-OHase) and 17,20-lyase (lyase). The results suggest that the imidazole-based compounds are highly potent inhibitors of both components, with N-7-phenyl heptyl imidazole (21) (IC(50)=0.32 microM against 17alpha-OHase and IC(50)=0.10 microM against lyase) and N-8-phenyl octyl imidazole (23) (IC(50)=0.25 microM against 17alpha-OHase and IC(50)=0.21 microM against lyase) being the two most potent compounds within the current study, in comparison to ketoconazole (KTZ) (IC(50)=3.76 microM against 17alpha-OHase and IC(50)=1.66 microM against lyase). Furthermore, consideration of the inhibitory activity against the two components show that the compounds tested are less potent towards the 17alpha-OHase component, a desirable property in the development of novel inhibitors of P450(17alpha). Structure-activity relationship determination of the range of compounds synthesised suggests that logP (log of the partition coefficient) is a key physicochemical factor in determining the overall inhibitory activity. In an effort to determine the viability of these compounds becoming potential drug candidates as well as to show specificity of these compounds, we undertook the biochemical evaluation of the synthesised compounds against two isozymes of 17beta-hydroxysteroid dehydrogenase [namely type 1 (17beta-HSD1) and type 3 (17beta-HSD3)] and 3beta-hydroxysteroid dehydrogenase (3beta-HSD). Consideration of the inhibitory activity possessed by the compounds considered within the current study against 3beta-HSD, 17beta-HSD1 and 17beta-HSD3 shows that there is no clear structure-activity relationship and that the compounds appear to possess similar inhibitory activity against both 3beta-HSD and 17beta-HSD3 whilst against 17beta-HSD1, the compounds appear to possess poor inhibitory activity at [I]=100 microM. Indeed, two of the most potent inhibitors of P450(17alpha), (compounds 21 and 23), were found to possess relatively good levels of inhibition against the three enzymes-compound 21 was found to possess approximately 32%, approximately 21% and approximately 37% inhibition whilst compound 23 was found to possess approximately 38%, approximately 30% and approximately 28% inhibition against 3beta-HSD, 17beta-HSD1 and 17beta-HSD3 respectively. We therefore concluded that the azole-based compounds synthesised within the current study are not suitable for further consideration as potential drug candidates due to their lack of specificity.

We report the synthesis, biochemical evaluation and rationalisation of the inhibitory activity of a number of azole-based compounds as inhibitors of the two components of the cytochrome P-450 enzyme 17alpha-hydroxylase/17,20-lyase (P450(17alpha)), i.e. 17alpha-hydroxylase (17alpha-OHase) and 17,20-lyase (lyase). The results suggest that the compounds synthesised are potent inhibitors, with 7-phenyl heptyl imidazole (11) (IC(50)=320 nM against 17alpha-OHase and IC(50)=100 nM against lyase); 1-[7-(4-fluorophenyl) heptyl] imidazole (14) (IC(50)=170 nM against 17alpha-OHase and IC(50)=57 nM against lyase); 1-[5-(4-bromophenyl) pentyl] imidazole (19) (IC(50)=500 nM against 17alpha-OHase and IC(50)=58 nM against lyase) being the most potent inhibitors within the current study, in comparison to ketoconazole (KTZ) (IC(50)=3.76 microM against 17alpha-OHase and IC(50)=1.66 microM against lyase). Furthermore, consideration of the inhibitory activity against the two components shows that all of the compounds tested are less potent towards the 17alpha-OHase in comparison to the lyase component, a desirable property in the development of novel inhibitors of P450(17alpha). From the modelling of these compounds onto the novel substrate heme complex (SHC) for the overall enzyme complex, the length of the compound, along with its ability to undergo interaction with the active site corresponding to the C(3) area of the steroidal backbone, are suggested to play a key role in determining the overall inhibitory activity.

Abstract
A series of 2-oxy-substituted 1-(1H-imidazol-1-yl)-4-phenylbutanes comprising imidazole-ketones, imidazole-dioxolanes, and imidazole-alcohols substituted with halogens in the phenyl ring were synthesized and evaluated as novel inhibitors of heme oxygenase which are structurally distinct from metalloporphyrins. The entire library of compounds was found to be highly active, with the bromine- and iodine-substituted derivatives being the most potent. The imidazole-dioxolanes were all selective for the HO-1 isozyme (inducible) and exhibited substantially lower activity toward the HO-2 isozyme (constitutive). The corresponding imidazole-ketones and imidazole-alcohols showed selectivity toward HO-1 to a lesser degree than the similarly substituted imidazole-dioxolanes.
