Molecular docking, ADMET and molecular dynamics simulation revealed metralindole as a multitargeted inhibitor for division kinases.

Lung cancer is the most common type of cancer in the world, and alone, in 2020, almost 2.21 million new cases were diagnosed, with 1.80 million deaths, and are increasing daily. Non-small cell lung (NSCLC) is the primary type of lung cancer, predominantly forms around 80% of cases compared to small cell carcinoma, and about 75% of patients are already in an advanced state when diagnosed. Despite notable advances in early diagnosis and treatment, the five-year survival rate for NSCLC is not encouraging. Therefore, it is crucial to investigate the molecular causes of non-small cell lung cancer to create more efficient therapeutic approaches. Lung cancer showed a more significant and persistent binding affinity and energy landscape with the target CDK2 staurosporine and FGF receptor-1. In this study, we have picked two essential target proteins, human cyclin-dependent kinase-2 and Human Protein Kinase CK2 Holoenzyme and screened the entire prepared DrugBank prepared library of 1,55,888 compounds and identified 2-(2-methyl-5-nitroimidazole-1-yl) ethanol (Metralindole) as a major inhibitor. Metralindole has displayed high docking scores of -5.159 Kcal/mol and -5.99 Kcal/mol with good hydrogen bonding and other bonding topologies such as van der Waals force, and ADMET results shown excellent bioavailability, outstanding solubility, no side effects, and toxicity. The molecular dynamics simulation for 100ns in a water medium confirmed the compound's stability and interaction pattern with the lowest deviation and fluctuations. Our in-silico study suggests Metralindole, an experimental compound, can effectively cure lung cancer. Further, the experimental validation of the compound is a must before any prescription.

The inhibitory and anticancer properties of Annona squamosa L. seed extracts.

Although Annona squamosa Linn. (Annonaceae) has been used in traditional medicine and is known to have several pharmacological properties, its impact on EGFR kinase has not been fully investigated. An assay (biochemical) was used to govern the potential of different A. squamosa seed extracts to scavenge free radicals in petroleum ether, acetone, ethanol, and methanol. We also tested A. squamosa leaf extracts for their ability to inhibit the growth of HEK 293, MCF7, and HepG2 cell lines. The PSE, ASE, ESE, and MSE all contained anti-cancer substances like anethole, cyclopentane, 1,1,3-trimethyl, and phosphonate oxide tributyl, according to phytochemical analysis. ESE extracts from A. squamosa seeds have been selected based on free radical generation probabilities, cytotoxicity studies, and phytochemical analysis. Subsequent insilico studies have been conducted, and the results have shown that interactions between compounds present in ESE extracts and the EGFR kinase are what give these compounds their inhibitory effects. Preliminary phytochemical and pharmacological activities were studied and reported. A. squamosa ESE extracts inhibited the growth of MCF7 cells, and a pharmacokinetic study showed that the compounds anethole, cyclopentane, 1,1,3-trimethyl, and phosphonium oxide tributyl had few undesirable side effects. These substances can be used to both prevent and treat cancer diseases.

O câncer de pulmão é o tipo de câncer mais comum no mundo, e, apenas em 2020, foram diagnosticados quase 2,21 milhões de novos casos, com 1,8 milhão de óbitos, e isso vem aumentando diariamente. O câncer de pulmão de células não pequenas (CPCNP) é o tipo primário de câncer de pulmão, forma que predomina em cerca de 80% dos casos em comparação com o carcinoma de pequenas células, e cerca de 75% dos pacientes já estão em estado avançado quando diagnosticados. Apesar dos avanços notáveis no diagnóstico e tratamento precoces, a taxa de sobrevida em cinco anos para CPCNP não é animadora. Portanto, é crucial investigar as causas moleculares do CPCNP para criar abordagens terapêuticas mais eficientes. O câncer de pulmão mostrou uma afinidade de ligação e perfil energético mais significativos e persistentes com a estaurosporina CDK2 alvo e o receptor-1 de FGF. Neste estudo, escolhemos duas proteínas-alvo essenciais, a quinase dependente de ciclina humana-2 e a holoenzima CK2 da proteína quinase humana, examinamos toda a biblioteca preparada pelo DrugBank de 1,55,888 compostos e identificamos 2-(2-metil-5-nitroimidazol-1-il) etanol (metralindol) como inibidor principal. O metralindol apresentou altas pontuações de ancoragem de -5,159 Kcal/mol e -5,99 Kcal/mol, com boas ligações de hidrogênio e outras topologias de ligação, como a força de Van der Waals, e os resultados do ADMET mostraram excelente biodisponibilidade e solubilidade, sem efeitos colaterais e toxicidade. A simulação de dinâmica molecular para 100ns em meio aquoso confirmou a estabilidade e o padrão de interação do composto com os menores desvios e flutuações. Nosso estudo in silico sugere que o metralindol, um composto experimental, pode efetivamente curar o câncer de pulmão. Além disso, a validação experimental do composto é obrigatória antes de qualquer prescrição.

Embora a Annona squamosa Linn. (Annonaceae) tenha sido utilizada na medicina tradicional e seja conhecida por diversas propriedades farmacológicas, seu impacto na EGFR quinase ainda não foi totalmente investigado. Um ensaio bioquímico foi utilizado para controlar o potencial de diferentes extratos de sementes de A. squamosa para eliminar radicais livres em éter de petróleo, acetona, etanol e metanol. Extratos de folhas de A. squamosa também foram analisados em relação à sua capacidade de inibir o crescimento de linhagens celulares HEK 293, MCF7 e HepG2. O PSE, ASE, ESE e MSE continham substâncias anticancerígenas como anetol, ciclopentano, 1,1,3-trimetil e óxido de fosfonato tributil, de acordo com a análise fitoquímica. Extratos de ESE de sementes de A. squamosa foram selecionados com base em probabilidades de geração de radicais livres, estudos de citotoxicidade e análise fitoquímica. Estudos in silico subsequentes foram realizados e os resultados mostraram que as interações entre os compostos presentes nos extratos de ESE e a EGFR quinase são o que confere a esses compostos seus efeitos inibitórios. As atividades fitoquímicas e farmacológicas preliminares foram estudadas e relatadas. Os extratos de ESSE de A. squamosa inibiram o crescimento de células MCF7, e um estudo farmacocinético mostrou que os compostos anetol, ciclopentano, 1,1,3-trimetil e óxido de fosfônio tributil tiveram poucos efeitos colaterais indesejáveis. Essas substâncias podem ser usadas para prevenir e tratar doenças cancerígenas.
