Discovery of Colossal Breathing-Caloric Effect under Low Applied Pressure in the Hybrid Organic–Inorganic MIL-53(Al) Material
(American Chemical Society, 2022-03-30)[Abstract] In this work, “breathing-caloric” effect is introduced as a new term to define very large thermal changes that arise from the combination of structural changes and gas adsorption processes occurring during ... -
Dolabelladienols A–C, New Diterpenes Isolated from Brazilian Brown Alga Dictyota pfaffii
(Multidisciplinary Digital Publishing Institute, 2014)[Abstract:]The marine brown alga Dictyota pfaffii from Atol das Rocas, in Northeast Brazil is a rich source of dolabellane diterpene, which has the potential to be used in future antiviral drugs by inhibiting reverse ... -
Enigmazole C: A Cytotoxic Macrocyclic Lactone and Its Ring-Opened Derivatives from a New Species of Homophymia Sponge
(American Chemical Society, 2022-03-02)[Abstract] A new macrolide, enigmazole C (1), and two additional analogues, enigmazoles E (2) and D (3), were obtained from a new species of the Homophymia genus as part of an ongoing discovery program at PharmaMar to study ... -
Evaluation of the in Vitro and in Vivo Efficacy of Ruthenium Polypyridyl Compounds Against Breast Cancer
(MDPI, 2021-08-18)[Abstract] The clinical success of cisplatin, carboplatin, and oxaliplatin has sparked the interest of medicinal inorganic chemistry to synthesize and study compounds with non-platinum metal centers. Despite Ru(II)–polypyridyl ... -
Extracellular Vesicles Enriched in Connexin 43 Promote a Senescent Phenotype in Bone and Synovial Cells Contributing to Osteoarthritis Progression
(Springer Nature, 2022)[Abstract] The accumulation of senescent cells is a key characteristic of aging, leading to the progression of age-related diseases such as osteoarthritis (OA). Previous data from our laboratory has demonstrated that high ... -
