Antiaging, Wound‐Healing Properties and Chemical Characterization of Crude Hydroalcoholic Extract and Fractions of Myrcia neoobscura

Chemistry &Biodiversity, EarlyView.
ABSTRACT The aim of this study was to characterize the phytochemical profile and potential antiaging and wound‐healing activities of 70% hydroalcoholic crude extract (CHE) from Myrcia neoobscura leaves and its fractions—insoluble (IF), ethyl acetate (EAF), and aqueous (AF)—for use in phytocosmetics for skin application.

Amazonian Cyanobacteria as a Source of Bioactive Compounds With Antimicrobial and Cytotoxic Properties

Chemistry &Biodiversity, EarlyView.
ABSTRACT Cyanobacteria are photosynthetic microorganisms known for producing diverse bioactive compounds. This study explores the bioactivity of extracts and fractions from Amazonian cyanobacteria and their pigment and phenolic compound production. A fraction from Synechococcus sp. CACIAM 05 showed cytotoxicity against hCMEC/D3 and MG‐63 cells.
