Abstract
The synthesis of 3-aminopyrrole using the amination reagent nitrosoarenes and homopropargylic amines catalyzed by I2 through cyclization and amination has been developed. This protocol features excellent functional group tolerance and mild reaction conditions, yielding 3-aminopyrroles in moderate to good yields without a metal catalyst. This method realizes the construction and amination of the 3-aminopyrroles in which nitrosoarenes serve as the amine source and oxidant.

Abstract
The androgen receptor (AR) plays a key role in the maintenance of muscle and bone and the support of male sexual-related functions, as well as in the progression of prostate cancer. Accordingly, AR-targeted therapies have been developed for the treatment of related human diseases and conditions. AR agonists are an important class of drugs in the treatment of bone loss and muscle atrophy. AR antagonists have also been developed for the treatment of prostate cancer, including metastatic castration-resistant prostate cancer (mCRPC). Additionally, selective AR degraders (SARDs) have been reported. More recently, heterobifunctional degrader molecules of AR have been developed, and four such compounds are now in clinical development for the treatment of human prostate cancer. This review attempts to summarize the different types of compounds designed to target AR and the current frontiers of research on this important therapeutic target.

Abstract
The androgen receptor (AR), a family of nuclear receptor proteins, stimulates the transcription of androgen-responsive genes. As its abnormal activation can cause the progression of prostate cancer, numerous types of ligands for AR have been developed as promising antagonists for the treatment of prostate cancer. We previously investigated the specific interactions between AR and nine types of existing non-steroidal ligands, using molecular simulations based on molecular mechanics and ab initio fragment molecular orbital methods. The results were confirmed to be comparable to the binding affinities of these ligands observed in experiments. We here propose novel ligands as potent inhibitors against AR and investigate their binding properties to AR, using the same molecular simulations. The results indicate that the most promising ligand binds stronger to AR than the existing non-steroidal ligands, and that our proposed ligand binds strongly to a mutant-type AR, which has drug resistance to the existing non-steroidal ligands.

Abstract
4,4-Disubstituted 4H-isoxazol-5-ones bearing a 1,4-naphthoquinone moiety undergo transformation into different types of benzoindolyl products depending on the different reaction conditions. A decarboxylative ring opening/ring closure promoted by catalytic [Ru(p-cymene)2Cl2]2 yields benzo[f]indole-4,9-diones. Alternatively, hydrogenation reactions provide the conversion of 4-(1,4-naphthoquinone)-substituted isoxazol-5-ones to benzo[g]indole compounds, with the level of reduction depending on the substituents present on the ring. Starting materials have been easily prepared by the functionalization of isoxazolinones with naphthoquinone under mild conditions.

Abstract
Treatment by androgen receptor (AR) antagonists is one of the regimens for prostate cancer. The prolonged treatment with AR antagonist leads to the expression of point mutation in the ligand binding domain of the AR. This point mutation causes resistance to AR antagonist by converting them into an agonist. The T887A mutated AR was frequently expressed in androgen independent prostate cancer (AIPC) patients. Through literature survey and molecular modelling, we have identified a novel AR antagonist having a bulky β-iminoenamine BF2 complex scaffold. The tested and standard ligands were screened in AR positive (LNCaP, MCF-7 and MDA-MB-453), AR negative (PC3), and non-cancerous (3T3) cell lines through anti-proliferation assay. The ligand, ARA3 was the most potent molecule among all the tested ligands and was 7.6 folds selective for AR positive cell lines. The mechanism of anti-prostate cancer activity of ARA3 was confirmed by western blot, qPCR, and apoptotic assays in LNCaP (T887A positive AR) cells. Structural activity relationship was derived by correlating the in-vitro and in-silico data. Consequently, we have identified the essential functional groups that could prevent the resistance concerning mutant AR. The ARA3 induces the apoptosis in AIPC cells by preventing the AR mediated activation of AKT pathway. The bicalutamide did not induce the apoptosis because it failed to prevent the AR mediated activation of AKT.

Abstract
Clinical resistance to the second-generation antiandrogen enzalutamide in castration-resistant prostate cancer (CRPC), despite persistent androgen receptor (AR) activity in tumors, highlights an unmet medical need for next-generation antagonists. We have identified and characterized tetra-aryl cyclobutanes (CBs) as a new class of competitive AR antagonists that exhibit a unique mechanism of action. These CBs are structurally distinct from current antiandrogens (hydroxyflutamide, bicalutamide, and enzalutamide) and inhibit AR-mediated gene expression, cell proliferation, and tumor growth in several models of CRPC. Conformational profiling revealed that CBs stabilize an AR conformation resembling an unliganded receptor. Using a variety of techniques, it was determined that the AR-CB complex was not recruited to AR-regulated promoters and, like apo AR, remains sequestered in the cytoplasm, bound to heat shock proteins. Thus, we have identified third-generation AR antagonists whose unique mechanism of action suggests that they may have therapeutic potential in CRPC.

Pd-catalyzed
cross-coupling reactions that form C–N bonds
have become useful methods to synthesize anilines and aniline derivatives,
an important class of compounds throughout chemical research. A key
factor in the widespread adoption of these methods has been the continued
development of reliable and versatile catalysts that function under
operationally simple, user-friendly conditions. This review provides
an overview of Pd-catalyzed N-arylation reactions found in both basic
and applied chemical research from 2008 to the present. Selected examples
of C–N cross-coupling reactions between nine classes of nitrogen-based
coupling partners and (pseudo)aryl halides are described for the synthesis
of heterocycles, medicinally relevant compounds, natural products,
organic materials, and catalysts.

Abstract
Androgen receptor (AR) is an attractive target for the treatment of prostate cancer. An integrated pharmacophore-based and docking-based virtual screening approach was applied to identify novel AR antagonists with a distinct scaffold. The candidate compounds were evaluated for their abilities to inhibit prostate cancer cell proliferation and AR target gene prostate-specific antigen gene expression as well as the binding affinity to AR. A potent lead compound, T3, was discovered with the ability to inhibit prostate-specific antigen expression, with a similar binding affinity to AR, and with antiproliferative effects on AR-positive prostate cancer cells similar to that of MDV3100.

Abstract
Activation of the androgen receptor is crucial for prostate cancer growth at all points of the illness. Current therapies targeting the androgen receptor, including androgen-depletion approaches and anti-androgens, do not completely inhibit the receptor activity. Prostate cancer cells develop resistance to castration by acquiring changes that include androgen-receptor overexpression and overexpression of enzymes involved in androgen biosynthesis, which result in reactivation of the receptor. Based on an understanding of these resistance mechanisms and androgen biosynthesis pathways, new anti-androgens and androgen-depleting agents have been developed. Notably, promising activity has been shown in early phase trials by MDV3100, a new anti-androgen designed for activity in prostate cancer model systems with overexpressed androgen receptor, and by abiraterone acetate, a CYP17A inhibitor that blocks steroid biosynthesis in the adrenal gland and possibly within the tumour. Both agents are undergoing phase 3 testing. Here, we review the basic science and clinical development of these and other agents.
