Abstract
Leuprorelin acetate microspheres, a common gonadotropin-releasing hormone agonist, have certain clinical benefits for prostate cancer (PCa). The present study aimed to compare the efficacy and safety of generic and branded leuprorelin acetate microspheres in patients with PCa. The present retrospective, observational study included 116 patients with PCa who received generic (Boennuokang®; Beijing Biote Pharmaceutical Co., Ltd.) or branded (Enantone®; Takeda Pharmaceutical Company, Ltd.) leuprorelin acetate microspheres via injection (commonly 3.75 mg once every 4 weeks), defined as the test (n=64) and reference (n=52) groups, respectively. The present study showed that testosterone levels at month (M) 3 (P<0.001), M6 (P=0.012) and M12 (P<0.001) were decreased in the test group compared with the reference group. However, prostate-specific antigen (PSA) levels at baseline, M1, M3, M6 and M12 were not significantly different between the test and reference groups (all P>0.05). The median (interquartile range) testosterone and PSA levels at M12 were 15.50 ng/dl (10.00-31.25 ng/dl) and 0.01 ng/ml (0.01-0.10 ng/ml), respectively, in the test group and 28.00 ng/dl (22.00-37.00 ng/dl) and 0.02 ng/ml (0.01-0.16 ng/ml), respectively, in the reference group. No significant differences were observed in the M1-baseline, M3-baseline, M6-baseline and M12-baseline changes of testosterone or PSA levels between the two groups (all P>0.050). Additionally, the incidence of all adverse events was not significantly different between the two groups (all P>0.050). Overall, Boennuokang® leuprorelin acetate microspheres exhibited a similar efficacy for suppression of testosterone and PSA levels with a comparable safety profile compared with Enantone® leuprorelin acetate microspheres in patients with PCa.

Abstract
INTRODUCTION Androgen-deprivation therapy (ADT) is the main therapy for patients with advanced and metastatic prostate cancer (PCa) and, in combination with radiotherapy, for patients with localized high-risk PCa. Due to its favorable tolerability among different treatments available for ADT, leuprorelin acetate is well established as the leading luteinizing hormone-releasing hormone (LHRH) analog. The development of second-generation leuprorelin acetate (LA) depot formulation (Eligard®, Recordati S.p.A) allowed a consistent and controlled release of leuprorelin between injections and a more efficient reduction of testosterone levels with respect to conventional LHRH agonists. AREAS COVERED This work provides a summary of the biological and clinical rationale for using LA to manage PCa and presents the current evidence about the therapeutic activity of the LA gel depot formulation, used as an advanced leuprorelin acetate delivery method. EXPERT OPINION Results of the registration studies and post-marketing clinical trials demonstrate that the LA gel depot provides long-term efficacy in the clinical practice and a good degree of tolerability. Overall, collected data suggest that the LA gel depot can represent the ADT reference therapy in advanced PCa.

Abstract
Although there are existing vaccines against severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), new COVID-19 cases are increasing due to low immunization coverage and the emergence of new variants. For this reason, new drugs to treat and prevent severe COVID-19 are needed. Here, we provide four different FDA-approved drugs against SARS-CoV-2 proteins involved in the entry and replication process, aiming to identify potential drugs to treat COVID-19. We use the main protease (Mpro), the spike glycoprotein (S protein), and RNA-dependent RNA polymerase (RdRp) as protein targets for anti- SARS-CoV-2 drugs. In our constructed database, we selected different drugs against each target (Mpro, S protein, and RdRp) based on their common interactions with relevant residues involved in viral entry at the host cell and replication. Furthermore, their stability inside the binding pocket, as well as their predicted binding-free energy, allow us to provide new insight into the possible drug repurposing of viomycin (interacting with Mpro) due to its interactions with key residues, such as Asn 143, Glu 166, and Gln 189 at the same time as hesperidin (interacting with the S protein) is interacting with residues Tyr 449, Ser 494, and Thr 500, keeping inside the predicted binding pocket, as well as interacting with residues in different variants of concern. Finally, we also suggest nystatin and elvitegravir (interacting with RdRp) as possible drugs due to their stability within the predicted pocket along the simulation and their interaction with key residues, such as Asp 760, Asp 761, and Asp 618. Altogether our results provide new knowledge about the possible mechanism of the inhibition of viomycin, hesperidin, elvitegravir, and nystatin to inhibit the viral life cycle of SARS-CoV-2 and some of its variants of concern (VOC). Additionally, some iodide-based contrast agents were also found to bind the S protein strongly, i.e., iohexol (−58.99 Kcal/mol), iotrolan (−76.19 Kcal/mol), and ioxilan (−62.37 Kcal/mol). Despite the information we report here as the possible strong interaction between these contrast agents and the SARS-CoV-2′s S protein, Mpro, and RdRp, we believe that further investigation, including chemical modifications in their structures, are needed for COVID-19 treatment.

Abstract
Background Prostate cancer is considered as the second leading cause of cancer related death in men worldwide and the third frequent cancer among Iranian men. Despite the use of PSA as the only biomarker for early diagnosis of prostate cancer, its application in clinical settings is under debate. Therefore, the introduction of new molecular markers for early detection of prostate cancer is needed. Methods In the present study we intended to evaluate the expression of IGSF1, Wnt5a, FGF14, and ITPR1 in prostate cancer specimens by real time PCR. Biopsy samples of 40 prostate cancer cases and 41 healthy Iranian men were compared to determine the relative gene expression of IGSF1, Wnt5a, FGF14, and ITPR1 by real time PCR. Results Our results showed that Wnt5a, FGF14, and IGSF1 were significantly overexpressed in the prostate cancer patients while the mean relative expression of ITPR1 showed a significant decrease in PCa samples compared to healthy controls. Conclusion According to results of the present study, the combination panel of IGSF1, Wnt5a, FGF14, and ITPR1 genes could be considered as potential genetic markers for prostate cancer diagnosis. However further studies on larger populations and investigating the clinicopathological relevance of these genes is needed.

Abstract
The androgen receptor (AR) is one of the main components in the development and progression of prostate cancer (PCa), and treatment strategies are mostly directed toward manipulation of the AR pathway. In the metastatic setting, androgen deprivation therapy (ADT) is the foundation of treatment in patients with hormone-sensitive prostate cancer (HSPC). However, treatment response is short-lived, and the majority of patients ultimately progress to castration-resistant prostate cancer (CRPC). Surmountable data from clinical trials have shown that the maintenance of AR signaling in the castration environment is accountable for disease progression. Study results indicate multiple factors and survival pathways involved in PCa. Based on these findings, the alternative molecular pathways involved in PCa progression can be manipulated to improve current regimens and develop novel treatment modalities in the management of CRPC. In this review, the interaction between AR signaling and other molecular pathways involved in tumor pathogenesis and its clinical implications in metastasis and advanced disease will be discussed, along with a thorough overview of current and ongoing novel treatments for AR signaling inhibition.

Abstract
Globally, prostate cancer (PCa) is the second most preponderant cancer in men. It contributes to the high mortality-to-incidence ratio reported in West Africa and Asia largely due to low screening. The mortality risk is determined or predicted based on the prevalence of high-risk or aggressive PCa using a scoring or grading system such as Gleason score (GS), Gleason grade (GG), and prostate-specific antigen (PSA) level. In this review, peer-reviewed articles found on databases such as Google Scholar, Scopus, Web of Science, PubMed Central and, EMBASE were selected based on adherence to clinical guidelines for the classification of PCa. In West Africa and Asia, the result revealed that the frequency of high-risk PCa was 42% and 51.2% based on GS, 48.8% and 25.3% based on GG pattern, and 87.5% and 44.3% based on PSA level >10 ng/mL, respectively. Data revealed a high prevalence of high-risk PCa both in West Africa and Asia when compared with developed countries. However, the prevalence of high-risk PCa is higher in West Africa than in Asia. Studies have shown that high-risk PCas are associated with germline mutations and such mutations are prevalent in blacks and Asians than in whites. Thus, testing for germline mutations in patients with GS of ≥ 7, GG ≥ 3, high prostate density, low prostate volume, and PSA levels of >4.0 ng/mL may identify those at risk of developing lethal PCa and could reduce the mortality rates in Asia and West Africa.
