Abstract
A new series of thieno[2,3-d][1,2,4]triazolo[1,5-a]pyrimidines was designed and synthesized using readily available starting materials, specifically, β-enaminoester. Their cytotoxicity was screened against three cancer cell lines, namely, MCF-7, HCT-116, and PC-3. 2-(4-bromophenyl)triazole 10b and 2-(anthracen-9-yl)triazole 10e afforded excellent potency against MCF-7 cell lines (IC50 = 19.4 ± 0.22 and 14.5 ± 0.30 μM, respectively) compared with doxorubicin (IC50 = 40.0 ± 3.9 μM). The latter derivatives 10b and 10e were further subjected to in silico ADME and docking simulation studies against EGFR and PI3K and could serve as ideal leads for additional modification in the field of anticancer research.

Abstract
Mixed martial arts (MMA) has always been surrounded by controversy due to the unusual muscle development of its participants, so it is crucial to know the strategies that have been implemented to reduce doping cases. The main purpose of this paper is to describe the various cases of doping detected by USADA in UFC MMA participants. In addition, strategies that are being developed to reduce cases of positive doping are proposed. From the UFC USADA database, doping cases were extracted, obtaining the substance or substances involved; the formula, physiological effect and the athletes involved; the dates of the sampling; if it was out of competition or in-competition and the sanction time. The substances that were most involved were found to be Ostarine (22), Clomiphene (9), Diuretics (10) and Stanozolol (9). Some sanctions were diminished because they were treated with contamination of supplements (cases of Ostarine) and cases of contamination of meat (Clomiphene). When contaminated supplements were reported, they were added to the list of high-risk supplements maintained as part of USADA’s online dietary supplement safety education and awareness resource—Supplement 411. There were also cases in which positive doping could be avoided through the early report of therapeutic use exemptions. The methodology that the USADA has implemented allows us to register the athletes with positive doping, check the risk of the supplements before being bought and provide a teaching portal. These efforts are necessary to implement in all countries in which MMA is practiced, avoiding the participation of doped martial artists.

Abstract
N 1-Substituted 1,2,4-triazoles are ubiquitous skeletons in medicinal agents, agrochemicals, and organic materials. Herein, an efficient and practical method for the synthesis of N1-allylated 1,2,4-triazoles via Pd-catalyzed allylic substitution of vinylethylene carbonates (VECs) with 1,2,4-triazoles has been developed. By using a catalyst generated in situ from Pd2(dba)3·CHCl3 and DPPE under mild conditions, the process allows rapid access to N1-allylated 1,2,4-triazoles bearing diverse functionalities in high yields with excellent N1-selectivities, linear-selectivities, and Z-stereoselectivities.

Abstract
A new series of benzimidazole, 1,2,4-triazole, and 1,3,5-triazine derivatives were designed and synthesized using a microwave irradiation synthetic approach utilizing 2-phenylacetyl isothiocyanate (1) as a key starting material. All the new analogues were evaluated as anticancer agents against a panel of cancer cell lines utilizing doxorubicin as a standard drug. Most of the tested derivatives exhibited selective cytotoxic activity against MCF-7 and A-549 cancer cell lines. Furthermore, the new target compounds 5, 6, and 7 as the most potent antiproliferative agents have been assessed as in vitro EGFRWT and EGFRT790M inhibitors compared to the reference drugs erlotinib and AZD9291. They represented more potent suppression activity against the mutated EGFRT790M than the wild-type EGFRWT. Moreover, the compounds 5, 6, and 7 down-regulated the oncogenic parameter p53 ubiquitination. A docking simulation of compound 6b was carried out to correlate its molecular structure with its significant EGFR inhibition potency and its possible binding interactions within the active site of EGFRWT and the mutant EGFRT790M.

Abstract
A new series of bis-1,2,3- and 1,2,4-triazoles (10a-m) were designed and efficiently synthesized using methyl salicylate as potential antimicrobial agents. All compounds were characterized by their proton & 13C NMR, IR, Mass spectral data, and elemental analysis. The final compounds 10a-m were in vitro screened for antimicrobial and antifungal activity against gram negative Pseudomonas aeruginosa, Escherichia coli, gram positive Bacillus subtilis, Staphylococcus aureus strains and Aspergillus niger & Saccharomyces cerevisiae. Majority of the synthesized compounds exhibited potent antimicrobial activity (MIC 3.9 µg/mL) and promising antifungal activity with the zone of inhibition (ZOI) 1.5-8.2 mm. Compounds like 10d and 10f exhibited best antimicrobial activity against S. aureus. The molecular docking analysis revealed that all the synthesized derivatives shown better binding affinities. Among all, compound 10f exhibited best scores. Hence, there was an assumption that introduction of para-chloro and bromo-phenyl aromatic groups on triazole moiety could result excellent antimicrobial activity. This substantial growth inhibitory activity of bis-1,2,3- and 1,2,4-triazole derivatives suggested these compounds could assist a new way in the development of lead molecules against microbial infection and antimicrobial resistance investigations.

Abstract
Tamoxifen, a selective estrogen receptor (ER) modulator (SERM), is widely used therapeutically for the treatment and prevention of breast cancer, but its use is associated with an increased risk of thrombosis. The mechanism of this adverse effect is still unclear. Arterial thromboses mostly consist of platelets that are adherent to ruptured endothelial surfaces. Several lines of evidence reported that tamoxifen stimulates platelet activation using different methodologies. In our preliminary study, tamoxifen exhibited potent antiplatelet activity in washed human platelets. The aim of this study was to examine the signal transduction pathways of tamoxifen in platelet activation. In this study, tamoxifen (3∼7 μmol/L) exhibited more potent activity in inhibiting platelet aggregation stimulated by collagen than other agonists (ie, thrombin). Tamoxifen inhibited collagen-stimulated platelet activation accompanied by relative Ca(+2) mobilization, thromboxane A(2) (TxA(2)) formation, and phospholipase C (PLC)γ2, protein kinase C (PKC), and mitogen-activated protein kinase (MAPK) phosphorylation (ie, p38 MAPK and extracellular signal-regulated kinase 1/2), but not hydroxyl radical (OH(•)) formation. However, tamoxifen did not increase nitric oxide (NO) release or vasodilator-stimulated phosphoprotein (VASP) phosphorylation in washed platelets. Furthermore, neither ICI 182,780, a pure ER antagonist, nor ODQ, an inhibitor of guanylate cyclase, significantly reversed the tamoxifen-mediated inhibition of platelet aggregation. In conclusion, this study demonstrates for the first time that tamoxifen possesses potent antiplatelet activity, the mechanism of which may be involved in the inhibition of the PLCγ2-PKC-p38 MAPK-TxA(2) cascade, thereby leading to the inhibition of platelet activation. In our study, the direct inhibition of platelet activation by tamoxifen possibly may provide new insights into understanding its cardiovascular effects.

Abstract
Male breast cancer is an uncommon condition. It often occurs in settings in which there is an imbalance between androgens and oestrogens. Genetics plays an important role, as many cases are associated with mutations in BRCA2 or other genes. Male breast cancer occurs at an older age than female breast cancer and is frequently diagnosed at a later stage. Tumors are predominantly oestrogen and progesterone positive. Prognosis is approximately equivalent to that of breast cancer in females when matched for age, stage and hormonal receptors. The recommended treatment for male breast cancer is similar to that for breast cancer in postmenopausal females. However, the presence of androgens in males has a strong effect on the hormonal milieu and the ability of male patients to respond to hormonal agents. When pharmacologic treatment is required, tamoxifen is effective for first-line therapy. Other hormonal approaches such as orchiectomy, aromatase inhibitors and androgen ablation may be useful in later lines of therapy.

Abstract
CONTEXT Use of aromatase inhibitors to suppress estrogen production is being actively investigated in a variety of experimental conditions in both females and males. Anastrozole (Arimidex) is a potent and selective reversible inhibitor of the aromatase enzyme in females. OBJECTIVE Our objective was to characterize the pharmacokinetics (PK) and pharmacodynamics (PD) of anastrozole in adolescent males with gynecomastia of less than 1 yr duration. The effect of anastrozole on breast size was also assessed as an exploratory aim. DESIGN We conducted a PK/PD open-label study. SETTING This clinical research center study was undertaken at pediatric academic centers. PATIENTS Forty-two boys with gynecomastia (mean age 13 +/- 1.8 yr; duration of gynecomastia 7.0 +/- 2.5 months; body mass index 28.3 +/- 5.9 kg/m(2)) were recruited. INTERVENTIONS Anastrozole, 1 mg, was given daily for 6 months. MAIN OUTCOMES We assessed PK/PD of anastrozole after 14 d daily dosing and changes in breast size (exploratory aim) by manual tape measurements (area) and ultrasound (volume) after 6 months. RESULTS Anastrozole was rapidly absorbed orally (time to reach maximum concentration, 1 h) with a slow apparent clearance of 1.54 liters/h and a terminal half-life of 46.8 h. Testosterone/estradiol ratios increased significantly with concomitant increase in LH/FSH concentrations indicating aromatase blockade. There was a reduction in breast area (approximately 63%) and breast volume (approximately 57%) in the study group as compared with baseline (P = 0.004). The drug was well tolerated. CONCLUSIONS Anastrozole is a potent aromatase inhibitor in adolescent males, with rapid absorption and slow elimination kinetics after oral dosing. Exploratory analysis of changes in breast size showed breast reduction in the cohort; this deserves further study.

Abstract
Aromatase is the cytochrome P450 enzyme responsible for the last step of estrogen biosynthesis, and aromatase inhibitors constitute an important class of drugs in clinical use for the treatment of breast cancer. Nonsteroidal aromatase inhibitors (NSAIs) are competitive inhibitors of aromatase, which bind to the enzyme active site by coordinating the iron atom present in the heme group of the P450 protein. Presently, third generation NSAIs are in use, and research efforts are being carried out both to identify new molecules of therapeutic interest and to clarify the mechanism of action. In this article, we present a survey of the compounds that have been recently reported as NSAIs, to provide a broad view on the general structure-activity relationships of the class. Moreover, starting from the current knowledge of the mechanistic aspects of aromatase action and from recent theoretical work on the molecular modeling of both enzyme and inhibitors, we try to indicate a way to integrate these different studies in view of a more general understanding of the aromeatase-inhibitor system. Finally, some aspects regarding the possible future development of the field are considered briefly.
