It is herein described the synthesis of a series of thirty novel 1,2,3-triazole-1,4 disubstituted compounds inspired on the known SRPKs inhibitor N-(2-(piperidin-1-yl)-5-(trifluoromethyl)phenyl)isonicotinamide (SRPIN340) and biological evaluation of them against human glioblastoma multiforme cell line U87MG. Starting with 1-fluoro-2 nitro-4-(trifluoromethyl)benzene (1), the substances were prepared via a five-step synthetic route. The crucial step corresponded to the copper-catalyzed cycloaddition reaction between trifluoromethyl phenyl azides and different alkynes. In general, the compounds were obtained with good yields and they were characterized utilizing spectroscopic (IR and NMR) and spectrometric (HRMS) techniques. The evaluation of the synthesized compounds at three different treatment time (24 h, 48 h, and 72 h) and concentrations (50, 100, and 150 µmol L-1) revealed that five derivatives were capable of reducing cell viability by 50% after 72 h of treatment at the highest concentration. On the contrary, three derivatives significantly increased cell viability being this effect more pronounced after 48 h of treatment. In this regard, it stands out the compound 2-((1-(2-morpholino-5-(trifluoromethyl)phenyl)-1H-1,2,3-triazol-4-yl)methyl)isoindoline-1,3-dione (7) which increased cell viability in approximately 300% after 48 h of treatment at 100 µmol L-1. The substances that increased cell viaiblity present as common structural features the presence of a saturated nitrogen-containing six-membered ring and carbonylated fragments.

RESUMO Em março de 2020, a Organização Mundial da Saúde (OMS) declarou como pandemia a doença causada pelo vírus SARS-CoV2, conhecida como COVID-19. O mundo do esporte acompanha e sofre os efeitos globais dessa enfermidade, com o adiamento ou cancelamento de competições, inclusive os Jogos Olímpicos de Tóquio 2020. Como proposta para contenção da doença, foi determinado o isolamento social. Apesar de importante, esta medida traz danos aos atletas olímpicos pelo afastamento do local de treinamento e de treinadores, assim como de sua equipe interdisciplinar. Portanto, entende-se a importância de estudar esses danos a fim de minimizá-los. De forma geral, acredita-se que a atividade física regular esteja associada à melhora do funcionamento do sistema imunológico. Assim, a falta de treinamento pode levar a consequências importantes para o desempenho e a saúde do atleta olímpico. Do ponto de vista da saúde do atleta, o comprometimento do sistema imunológico pela redução da regularidade do exercício físico deixa o atleta mais vulnerável a contrair e desenvolver infecções ou outras patologias. Além disso, o risco de lesões considerando a diminuição da realização dos trabalhos preventivos é evidente nessa população. As reduções da carga e da intensidade de treino podem provocar mudanças na composição corporal do atleta e afetar diversos componentes da aptidão cardiorrespiratória, assim como reduzir níveis de força e potência muscular. Com relação à saúde mental do atleta, dois aspectos são os mais desafiadores: o isolamento e a incerteza. A partir dos possíveis danos causados pelo isolamento social, entende-se a necessidade de um trabalho específico e em conjunto, na tentativa de minimizá-los. Neste trabalho serão abordados os seguintes tópicos: (I) contexto: transmissão, sintomas, diagnóstico, tratamento, critérios de alta, isolamento e consequências pós-pandemia; (II) danos e propostas: nutricionais, fisiológicas, biomecânicas, bioquímicas e psicológicas. Nível de evidência II; Artigo de Revisão.

ABSTRACT In March 2020, the World Health Organization (WHO) declared the disease caused by the SARS-CoV2 virus, known as COVID-19, to be a pandemic. The sporting world, too, is suffering from the global effects of this disease, with the postponement or cancellation of competitions, including the 2020 Tokyo Olympic Games. As a proposal for containing the disease, social isolation was declared. Despite the importance of this measure, it was harmful for Olympic athletes, as they had to stay away from their training site and trainers, as well as their interdisciplinary teams. It is therefore important to study this harm caused, in order to minimize it. In general, it is believed that regular physical activity is associated with improved immune system functioning. The lack of training can therefore have significant consequences for the performance and health of the Olympic athlete. From the athlete's point of view, the impaired immune system, due to the reduced frequency of physical exercise, leaves them more vulnerable to contracting or developing infections or other diseases. The risk of harm due to the decreased performance of preventive works is also evident in this population. The reductions in training load and intensity can cause changes in the athlete's body composition and affect various aspects of cardiorespiratory fitness, as well as reducing strength levels and muscle potency. In relation to the athlete's mental health, two aspects are particularly challenging: isolation and uncertainty. Based on the possible harm caused by social isolation, the need is seen for a specific and joint work, in an attempt to minimize it. This work addresses the following topics: (I) context: transmission, symptoms, diagnosis, treatment, discharge criteria, isolation and post-pandemic consequences; (II) harm and proposals: nutritional, physiological, biomechanical and psychological. Level of evidence II; Review Article.

The demand for new insecticides is increasing due to the appearance of insect populations that are resistant to currently used products. New insecticides should be efficient in controlling pests and present low toxicity to non-target organisms. Ascia monuste (Lepidoptera: Pieridae) is a destructive pest of cole vegetables, and the fire ant Solenopsis saevissima (Hymenoptera: Formicidae) is an important predator of these caterpillars in brassica crops. Tetragonisca angustula (Hymenoptera: Apidae) is very important in pollinating many plants and providing honey. Therefore, this study evaluated the toxicity of synthetic amides to A. monuste and its selectivity in favor of S. saevissima and T. angustula. The amides (2E,4E)-N-propylhexa-2,4-dienamide (3) and (2E, 4E)-N-butylhexa-2,4-dienamide (4) caused high (96 and 93%, respectively) and fast (48 h) mortality of A. monuste. The amides 3 and 4 were not harmful to the predator (mortality of 5.7% for amide 3 and 7.14% for amide 4) and were slightly harmful to the pollinator (mortality of 38.57% for amide 3 and 28.12% for amide 4). The amides 3 and 4 are promising, as insecticides, due to the high and rapid mortality of A. monuste with low and moderate toxicity to S. saevissima and T. angustula, respectively.
