Abstract
Eukaryotic translation initiation factors (eIFs) are highly expressed in cancer cells, especially eIF4E, the central regulatory node driving cancer cell growth and a potential target for anticancer drugs. eIF4E-targeting strategies primarily focus on inhibiting eIF4E synthesis, interfering with eIF4E/eIF4G interactions, and targeting eIF4E phosphorylation and peptide inhibitors. Although some small-molecule inhibitors are in clinical trials, no eIF4E inhibitors are available for clinical use. We provide an overview of the regulatory mechanisms of eIF4E and summarize the progress in developing and discovering eIF4E inhibitor strategies. We propose that interference with eIF4E/eIF4G interactions will provide a new perspective for the design of eIF4E inhibitors and may be a preferred strategy.

Abstract
Neonicotinoid insecticides acting on the insect nicotinic acetylcholine receptors (nAChRs) play an essential role in contemporary pest control. In the present study, a series of novel neonicotinoid analogues with conjugated diene were synthesized. Bioassays indicated that compounds A3 and A12 had LC50 values of 1.26 and 1.24 mg/L against Myzus persicae, respectively, which were comparable to that of imidacloprid (IMI, LC50 = 0.78 mg/L). Density functional theory (DFT) calculations were performed to explain the differences in the insecticidal activities of target compounds. Molecular docking results indicate that compounds A3 and A12 interact favorably with Lymnaea stagnalis AChBP. The hydrolysis experiments confirmed that the stability of compounds A3 and A12 was enhanced in water.

Abstract
Aberrant translation of proteins that promote cell proliferation is an essential factor that defines oncogenic processes and cancer. The process for ribosomal translation of proteins from mRNA requires an essential initiation step which is controlled by the protein eIF4E, which binds the RNA 5'-cap and forms the eIF4F complex that subsequently translates protein. Typically, eIF4E is activated by phosphorylation on Ser209 by MNK1 and MNK2 kinases. Substantial work has shown that eIF4E and MNK1/2 are dysregulated in many cancers and this axis has therefore become an active area of interest for developing new cancer therapeutics. This review summarizes and discusses recent work to develop small molecules that target different steps in the MNK-eIF4E axis as potential cancer therapeutics. The aim of this review is to cover the breadth of different molecular approaches being taken and the medicinal chemistry basis for their optimization and testing as new cancer therapeutics.

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
![]()
Sphingosine 1-phosphate
(S1P) is a pleiotropic signaling molecule
that interacts with five native G-protein coupled receptors (S1P1–5)
to regulate cell growth, survival, and proliferation. S1P has been
implicated in a variety of pathologies including cancer, kidney fibrosis,
and multiple sclerosis. As key mediators in the synthesis of S1P,
sphingosine kinase (SphK) isoforms 1 and 2 have attracted attention
as viable targets for pharmacologic intervention. In this report,
we describe the design, synthesis, and biological evaluation of sphingosine
kinase 2 (SphK2) inhibitors with a focus on systematically introducing
rigid structures in the aliphatic lipid tail present in existing SphK2
inhibitors. Experimental as well as molecular modeling studies suggest
that conformationally restricted “lipophilic tail” analogues
bearing a bulky terminal moiety or an internal phenyl ring are useful
to complement the “J”-shaped sphingosine binding pocket
of SphK2. We identified 14c (SLP9101555) as a potent
SphK2 inhibitor (Ki = 90 nM) with 200-fold
selectivity over SphK1. Molecular docking studies indicated key interactions:
the cyclohexyl ring binding in the cleft deep in the pocket, a trifluoromethyl
group fitting in a small side cavity, and a hydrogen bond between
the guanidino group and Asp308 (amino acid numbering refers to human
SphK2 (isoform c) orthologue). In vitro studies using
U937 human histiocytic lymphoma cells showed marked decreases in extracellular
S1P levels in response to our SphK2 inhibitors. Administration of 14c (dose: 5 mg/kg) to mice resulted in a sustained increase
of circulating S1P levels, suggesting target engagement.

Abstract
INTRODUCTION Endogenous Cushing's syndrome (CS) is a set of disorders caused by chronic exposure to excess glucocorticoids induced by neuroendocrine tumors in pituitary, adrenals, and infrequently other sites (ectopic ACTH syndrome). Due to various comorbidities, CS patients exhibit higher risks of cardiovascular diseases and thus increased mortality. Pharmaceutical therapy is an important constituent of treatment regimen. Areas covered: Patents published since 2012 are reviewed, which claim therapeutic compounds interfering with ACTH secretion and down-stream signal transduction, inhibiting cortisol biosynthesis and antagonizing glucocorticoid receptors. Advances focus on a) new analogues with improved efficacy and PK properties or less off-target toxicity; b) existing drugs (candidates) being repurposed to treat CS; and c) novel strategies such as selective inhibition of CYP11B1. Expert opinion: New compounds against established targets need to be developed because current drugs lack selectivity leading to off-target toxicity. Selective inhibition of CYP11B1 is a novel alternative strategy and is potentially versatile in controlling all types of hypercortisolism. Selective multi-targeting enzymes in steroidogenesis network is promising due to potential synergistic effects. However, doses toward each targets are not feasible to adjust because the corresponding intrinsic potencies are rigid. Targeting PRKACA mutations is promising in treating CS caused by adrenal adenomas.

Abstract
The inhibition of 11β-hydroxylase is a promising strategy for the treatment of Cushing's syndrome, in particular for the recurrent and subclinical cases. To achieve proof of concept in rats, efforts were paid to identify novel lead compounds inhibiting both human and rat CYP11B1. Modifications on a potent promiscuous inhibitor of hCYP11B1, hCYP11B2 and hCYP19 (compound IV) that exhibited moderate rCYP11B1 inhibition led to compound 8 as a new promising lead compound. Significant improvements compared to starting point IV were achieved regarding inhibitory potency against both human and rat CYP11B1 (IC50 values of 2 and 163 nM, respectively) as well as selectivity over hCYP19 (IC50 = 1900 nM). Accordingly, compound 8 was around 7- and 28-fold more potent than metyrapone regarding the inhibition of human and rat CYP11B1 and exhibited a comparable selectivity over hCYP11B2 (SF of 3.5 vs 4.9). With further optimizations on this new lead compound 8, drug candidates with satisfying profiles are expected to be discovered.

Abstract
CYP11B2 inhibition is a promising treatment for diseases caused by excessive aldosterone. To improve the metabolic stability in human liver miscrosomes of previously reported CYP11B2 inhibitors, modifications were performed via a combination of ligand- and structure-based drug design approaches, leading to pyridyl 4,5-dihydro-[1,2,4]triazolo[4,3-a]quinolones. Compound 26 not only exhibited a much longer half-life (t1/2 ≫ 120 min), but also sustained inhibitory potency (IC50 = 4.2 nM) and selectivity over CYP11B1 (SF = 422), CYP17, CYP19, and a panel of hepatic CYP enzymes.

Abstract
The synthesis and in vitro and in vivo antibreast and antiprostate cancers activities of novel C-4 heteroaryl 13-cis-retinamides that modulate Mnk-eIF4E and AR signaling are discussed. Modifications of the C-4 heteroaryl substituents reveal that the 1H-imidazole is essential for high anticancer activity. The most potent compounds against a variety of human breast and prostate cancer (BC/PC) cell lines were compounds 16 (VNHM-1-66), 20 (VNHM-1-81), and 22 (VNHM-1-73). In these cell lines, the compounds induce Mnk1/2 degradation to substantially suppress eIF4E phosphorylation. In PC cells, the compounds induce degradation of both full-length androgen receptor (fAR) and splice variant AR (AR-V7) to inhibit AR transcriptional activity. More importantly, VNHM-1-81 has strong in vivo antibreast and antiprostate cancer activities, while VNHM-1-73 exhibited strong in vivo antibreast cancer activity, with no apparent host toxicity. Clearly, these lead compounds are strong candidates for development for the treatments of human breast and prostate cancers.

Abstract
![]()
The
4EGI-1 is the prototypic inhibitor of eIF4E/eIF4G interaction,
a potent inhibitor of translation initiation in vitro and in vivo
and an efficacious anticancer agent in animal models of human cancers.
We report on the design, synthesis, and in vitro characterization
of a series of rigidified mimetic of this prototypic inhibitor in
which the phenyl in the 2-(4-(3,4-dichlorophenyl)thiazol-2-yl) moiety
was bridged into a tricyclic system. The bridge consisted one of the
following: ethylene, methylene oxide, methylenesulfide, methylenesulfoxide,
and methylenesulfone. Numerous analogues in this series were found
to be markedly more potent than the parent prototypic inhibitor in
the inhibition of eIF4E/eIF4G interaction, thus preventing the eIF4F
complex formation, a rate limiting step in the translation initiation
cascade in eukaryotes, and in inhibition of human cancer cell proliferation.

Abstract
As the first in class steroid 17α-hydroxylase/C17,20-lyase (CYP17) inhibitor, abiraterone acetate (of which the active metabolite is abiraterone) has been shown to improve overall survival in patients with castration-resistant prostate cancer (CRPC)--in those who are chemotherapy-naive and those previously treated with docetaxel. Furthermore, the clinical success of abiraterone demonstrated that CRPC, which has previously been regarded as an androgen-independent disease, is still driven, at least in part, by androgens. More importantly, abiraterone is a 'promiscuous' drug that interacts with a number of targets, which dictate its clinical benefits and adverse effects profile. Besides CYP17 inhibition, abiraterone acts as an antagonist to the androgen receptor and inhibits 3β-hydroxysteroid dehydrogenase--two effects that potentially contribute to its antitumour effects. However, the inhibition of the 17α-hydroxylase activity of CYP17, CYP11B1 and a panel of hepatic CYP enzymes leads to adverse effects and toxicities that include secondary mineralocorticoid excess. Abiraterone is also associated with increased incidence of cardiac disorders. Under such circumstances, development of new CYP17 inhibitors as an additional line of defence is urgently needed. To achieve enhanced clinical benefits, new strategies are being explored that include selective inhibition of the C17,20-lyase activity of CYP17 and multi-targeting strategies that affect androgen synthesis and signalling at different points. Some of these strategies-including the drugs orteronel, VT-464 and galeterone--are supported by preclinical data and are being explored in the clinic.

Abstract
Dual CYP17/CYP11B2 inhibitors are proposed as a novel strategy for the treatment of prostate cancer to reduce risks of cardiovascular diseases. Via a combination of ligand- and structure-based approaches, a series of dual inhibitors were designed leading to the 2-(3-pyridyl)naphthalenes 10 and 11 with strong inhibition of both enzymes (IC50 values around 20 nM) and excellent selectivities over CYP11B1, CYP19, and CYP3A4. These compounds are considered as promising candidates for further in vivo evaluation.

Abstract
Since 2010, six drugs have been approved for the treatment of castration-resistant prostate cancer, i.e., CYP17 inhibitor Abiraterone, androgen receptor antagonist Enzalutamide, cytotoxic agent Cabazitaxel, vaccine Sipuleucel-T, antibody Denosumab against receptor activator of nuclear factor kappa B ligand and radiopharmaceutical Alpharadin. All these drugs demonstrate improvement on overall survival, expect for Denosumab, which increases the bone mineral density of patients under androgen deprivation therapy and prolongs bone-metastasis-free survival. Besides further CYP17 inhibitors (Orteronel, Galeterone, VT-464 and CFG920), androgen receptor antagonists (ARN-509, ODM-201, AZD-3514 and EZN-4176) and vaccine Prostvac, more drug candidates with various mechanisms or new indications of launched drugs are currently under evaluation in different stages of clinical trials, including various kinase inhibitors and platinum complexes. Some novel strategies have also been proposed aimed at further potentiation of antitumor effects or reduction of side effects and complications related to treatments. Under these flourishing circumstances, more investigations should be performed on the optimal combination or the sequence of treatments needed to delay or reverse possible resistance and thus maximize the clinical benefits for the patients.

Abstract
A screening of structurally different steroid hormone synthesis inhibitors was performed in order to find a starting point for the development of a new inhibitor of the bifunctional steroidogenic enzyme CYP17A1. Emphasis was placed on determination of selectivity between the two catalytic steps, namely 17α-hydroxylase and C(17,20)-lyase. For that purpose a new inhibition assay has been developed. Hits identified within this novel assay demonstrated selective inhibition of CYP17A1 lyase activity, and thus mark the basis for the development of selective C(17,20)-lyase inhibitors for the treatment of prostate cancer.

Abstract
Aldosterone synthase (CYP11B2) is a promising therapeutic target for the treatment of cardiovascular diseases related to abnormally high aldosterone levels. On the basis of our previously identified lead compounds I–III, a series of 3-pyridinyl substituted aliphatic cycles were designed, synthesized and tested as CYP11B2 inhibitors. Aromaticity abolishment of the core was successfully applied to overcome the undesired CYP1A2 inhibition. This study resulted in a series of potent and selective CYP11B2 inhibitors, with compound 12 (IC50 = 21 nM, SF = 50) as the most promising one, which shows no inhibition toward CYP1A2 at 2 µM. The design conception demonstrated in this study can be helpful in the optimization of CYP inhibitor drugs regarding CYP1A2 selectivity.

Abstract
Background: A highly sensitive, specific and high-throughput LC–ESI-MS/MS method in the positive mode has been developed and validated for the quantitation of Orteronel® (TAK-700) in rat plasma using YM-55208 as an internal standard. Results: The assay procedure involves extraction of Orteronel and internal standard from rat plasma with liquid–liquid extraction method. Chromatographic separation was achieved using an isocratic mobile phase at a flow rate of 0.6 ml/min on an Atlantis dC18 column with a total run time of 2.5 min. The MS/MS ion transitions monitored were m/z 308.4→95.0 for Orteronel and m/z 262.3→194.2 for IS. Method validation was performed as per US FDA guidelines. The LLOQ achieved was 0.42 ng/ml and the linearity range extended from 0.42 to 814 ng/ml. Conclusion: The results met the acceptance criteria. The validated method was successfully applied to characterize the pharmacokinetic parameters of Orteronel in rat plasma.

Abstract
Protein-Ligand docking is a powerful technique routinely employed in structure-based drug design. Despite many reported success stories, docking is not always able to provide an accurate and easily interpretable prediction of the structure of the bound complex formed by a small organic molecule and a pharmacologically relevant target. Cluster analysis can represent a versatile and readily available postprocessing tool to be employed in combination with protein-ligand docking to simplify the evaluation of the results and help to overcome present limitations of docking protocols.

Abstract
A novel naphthylmethylimidazole derivative 1 and its related compounds were identified as 17,20-lyase inhibitors. Based on the structure-activity relationship around the naphthalene scaffold and the results of a docking study of 1a in the homology model of 17,20-lyase, the 6,7-dihydro-5H-pyrrolo[1,2-c]imidazole derivative (+)-3c was synthesized and identified as a potent and highly selective 17,20-lyase inhibitor. Biological evaluation of (+)-3c at a dose of 1mg/kg in a male monkey model revealed marked reductions in both serum testosterone and dehydroepiandrosterone concentrations. Therefore, (+)-3c (termed orteronel [TAK-700]) was selected as a candidate for clinical evaluation and is currently in phase III clinical trials for the treatment of castration-resistant prostate cancer.

Abstract
Evaluation of: Reid AH, Attard G, Danila DC et al. Significant and sustained antitumor activity in post-docetaxel, castration-resistant prostate cancer with the CYP17 inhibitor abiraterone acetate. J. Clin. Oncol. 28(9), 1489-1495 (2010). Inhibition of cytochrome P17 (CYP17), which is involved in androgen synthesis, is a promising therapeutic strategy for castration-resistant prostate cancer (CRPC). The first multicenter, Phase II study of a CYP17 inhibitor, the small molecule abiraterone acetate, has been conducted on 47 patients that received prior docetaxel chemotherapy for prostate cancer. With 1000 mg once daily, declines of more than 50% in prostate-specific antigen and circulating tumor cell counts were seen in 51 and 63% of patients, respectively. Overall, the drug was well tolerated and had a significant antitumor activity with symptomatic improvements. Reid and colleagues' study highlights abiraterone as a key molecule in CRPC treatment and gives further evidence of the involvement of the androgen receptor signaling axis in the disease. A randomized Phase III trial is ongoing to define the prognostic impact of this drug among the very limited arsenal of drugs currently available for CRPC. In the meantime, other CYP17 inhibitors are expected to show a favorable safety and efficacy profile, as are other novel powerful agents and combinatorial therapeutic strategies.

Abstract
Virtual screening of chemical libraries following experimental assays of drug candidates is a common procedure in structure based drug discovery. However, the relationship between binding free energies and biological activities (pIC50) of drug candidates is still an unsolved issue that limits the efficiency and speed of drug development processes. In this study, the relationship between them is investigated based on a common molecular descriptor set for human cytochrome P450 enzymes (CYPs). CYPs play an important role in drug-drug interactions, drug metabolism, and toxicity. Therefore, in silico prediction of CYP inhibition by drug candidates is one of the major considerations in drug discovery. The combination of partial least-squares regression (PLSR) and a variety of classification algorithms were employed by considering this relationship as a classification problem. Our results indicate that PLSR with classification is a powerful tool to predict more than one output such as binding free energy and pIC50 simultaneously. PLSR with mixed-integer linear programming based hyperboxes predicts the binding free energy and pIC50 with a mean accuracy of 87.18% (min: 81.67% max: 97.05%) and 88.09% (min: 79.83% max: 92.90%), respectively, for the cytochrome p450 superfamily using the common 6 molecular descriptors with a 10-fold cross-validation.
