Preclinical evidence of the anti-inflammatory effect and toxicological safety of aryl-cyclohexanone in vivo.

Background: Respiratory distress syndrome is a complex inflammatory condition defined by the presence of acute hypoxemia and cellular infiltration with diffuse alveolar injury following a tissue injury, such as acute lung injury. The inflammatory process involved in this pathology is a defense mechanism of the body against infectious agents and/or tissue injuries. However, when the condition is not reversed, it becomes a significant cause of tissue damage, sometimes leading to loss of function of the affected organ.

Evaluation of the anti-inflammatory effect of 1,4-dihydropyridine derivatives.

Introduction: Inflammation is a physiological event that protects the organism against different factors that lead to loss of tissue homeostasis. Dihydropyridine (DHP) derivatives are heterocyclic compounds known for their different biological activities, including anti-inflammatory activities.

Objective: To evaluate the anti-inflammatory activity of 1,4-dihydropyridine (1,4-DHP) derivatives using anti-inflammatory models in vitro, in RAW264.

Inhibitory effects of 190 compounds against SARS-CoV-2 M protein: Molecular docking interactions.

COVID-19 has caused many deaths since the first outbreak in 2019. The burden on healthcare systems around the world has been reduced by the success of vaccines. However, population adherence and the occurrence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants are still challenging tasks to be affronted.

Inhibitory effect of hydroalcoholic extract of Cunila spicata Benth. on phlogistic agents-induced cellular migration in the airways of mice.

Ethnopharmacological Relevance: Cunila spicata Benth. Is a creeping and aromatic plant that has an ethnopharmacological indication in the southern region of Brazil, in the Araucaria Forest biome. It's used as an alternative therapy for respiratory diseases for men and animals since the "tropeirista" movement in colonial Brazil.

Semisynthetic Sesquiterpene Lactones Generated by the Sensibility of Glaucolide B to Lewis and Brønsted-Lowry Acids and Bases: Cytotoxicity and Anti-Inflammatory Activities.

Sesquiterpene lactone (SL) subtypes including hirsutinolide and cadinanolide have a controversial genesis. Metabolites of these classes are either described as natural products or as artifacts produced via the influence of solvents, chromatographic mobile phases, and adsorbents used in phytochemical studies. Based on this divergence, and to better understand the sensibility of these metabolites, different pH conditions were used to prepare semisynthetic SLs and evaluate the anti-inflammatory and antiproliferative activities.
