Avaliação dos repelentes: efeitos na saúde humana / Evaluation of repellents: effects on human health / Evaluación de repelentes: efectos sobre la salud humana

Este artigo teve como objetivo avaliar os efeitos do uso de repelentes na população brasileira. Para alcançar o objetivo proposto, foram utilizadas as metodologias da revisão de literatura e a pesquisa documental junto à ANVISA referentes aos repelentes registrados e comercializados no Brasil. De acordo com a RDC nº 7 de 2015 da ANVISA, os repelentes são classificados como produtos de Grau 2, compostos por Produtos de Higiene Pessoal, Cosméticos e Perfumes. Nessa categoria, constatou-se a existência de 113 produtos registrados para comercialização no Brasil. Verificou-se que, apesar do aumento do consumo devido às doenças causadas por picada dos mosquitos Aedes aegypti, a maioria dos repelentes comercializados possuem como princípio ativo as substâncias DEET, Icaridina ou IR3535, não resultando em reações tóxicas relevantes para a população, visto que, essas substâncias são de baixa toxicidade ou atóxicas, como é o caso do IR3535. Faz-se necessário considerar que o uso desses produtos deve seguir rigorosamente as orientações dos fabricantes disponíveis nos rótulos das embalagens no que tange à aplicação, reaplicação, frequência e uso específico para crianças, gestantes e lactantes. No que se refere à eficácia, a Icaridina apresenta-se como mais eficaz que o IR3535 quando considerados os fatores tempo de proteção versus concentração do princípio ativo. Entretanto, a Icaridina, em alguns casos, pode apresentar moderada toxicidade, enquanto que, o IR3535 é atóxico. Observa-se ainda, que mesmo diante desse cenário, o DEET é o mais comercializado e amplamente estudado no país.

This article aimed to evaluate the effects of the use of repellents in the Brazilian population. To achieve the proposed objective, the methodologies of literature review and documentary research with ANVISA regarding repellents registered and marketed in Brazil were used. According to ANVISA's RDC No. 7 of 2015, repellents are classified as Grade 2 products, composed of Personal Hygiene Products, Cosmetics and Perfumes. In this category, it was found the existence of 113 products registered for commercialization in Brazil. It was found that, despite the increased consumption due to diseases caused by bites from Aedes aegypti mosquitoes, most repellents marketed have as active ingredients the substances DEET, Icaridin or IR3535, not resulting in toxic reactions relevant to the population, since these substances are of low toxicity or non- toxic, as is the case of IR3535. It is necessary to consider that the use of these products should strictly follow the manufacturers' guidelines available on the packaging labels regarding application, reapplication, frequency and specific use for children, pregnant and lactating women. With regard to efficacy, Icaridin is more effective than IR3535 when considering the factors protection time versus concentration of the active ingredient. However, Icaridin, in some cases, may present moderate toxicity, while IR3535 is non- toxic. It is also observed that, even in this scenario, DEET is the most marketed and widely studied in the country.

The epidemic of COVID-19 has brought great challenges to the global public health prevention and control system combined with clinical diagnosis and treatment system, and it makes the development of effective antiviral drugs an important task in current pharmaceutical research. Traditional Chinese medicine (TCM) has played an important role in the prevention and control of COVID-19. Due to its numerous chemical components and various structural types, TCM becomes a natural library for searching for lead compounds against SARS-CoV-2. In this study, a novel dual-target surface plasmon resonance (SPR) biosensor was developed for S protein receptor binding domain (SRBD) and angiotensin converting enzyme 2 (ACE2) which are two key proteins in the process of SARS-CoV-2 invading cells according to characteristics of synergistic effects of multiple components and comprehensive regulation of multiple targets of TCM. The SPR biosensor was applied to screen and identify active components from six TCMs, and daidzin from Puerariae Lobatae Radix was identified to bind with SRBD and ACE2. The affinity constant (KD) of daidzin and ACE2 was 5.18 μmol·L-1 through the SPR affinity assay. Competitive ELISA assay showed that daidzin could inhibit the binding of SRBD and ACE2, and the inhibition rate of daidzin (20 μmol·L-1) was 38.6%. Molecular docking experiments further confirmed that daidzin had the best binding near the binding region of SRBD-ACE2 complex. This study shows that the dual-target SPR screening system is accurate and efficient, and is particularly suitable for screening of complex drug systems and effective substances study of TCM. It provides a material basis for exploring the mechanism of TCM active constituents against SARS-CoV-2, and provides a source of lead compounds for the development of anti-SARS-CoV-2 drugs.
