Characterization of Liquid Dosage Forms of Atenolol and Enalapril Maleate for O...
Mota, Sandra; Torres, Ana; Quintas, Clara; Peres, António M.; Ferreiro, Nuno Manuel; Cruz, Rebeca; Ferreira, Helena; Almeida, Isabel F.; Casal, SusanaThe limited availability of pharmaceutical formulations tailored for cardiovascular diseases in both pediatric and geriatric populations generates the need for compounded dosage forms to guarantee precise dosing and medication adherence. This study aimed to analyze the physicochemical properties and stability of formulations of atenolol and enalapril maleate prepared with a proprietary oral vehicle, SuspendIt®....
Comparative Studies on the Photoreactivity, Efficacy, and Safety of Depigmentin...
Mota, Sandra; Rosa, Gonçalo P.; Barreto, Maria Carmo; Garrido, Jorge; Sousa, Emília; Cruz, Maria T.; Almeida, Isabel F.; Quintas, Clara; Garrido, JorgeDepigmenting products are increasingly used to counteract skin hyperpigmentation and related psychosocial issues. This study aimed to compare different depigmenting agents—4-butylresorcinol; bakuchiol; tranexamic acid; ascorbyl glucoside; α-arbutin; and ascorbic acid—for photoreactivity; tyrosinase inhibition; and safety. Photoreactivity was assessed using the Reactive Oxygen Species assay. In vitro tyrosinase ...

Unexpected Therapeutic Effects of Common Drugs: Lessons from 15 Years of Drug R...
Gonçalves, Jorge Manuel Moreira; Quintas, Clara; Silva, Dany; Queiroz, Glória; Fresco, PaulaDrug repurposing (DR) is one of the expressions that has been used to translate the process of discovering new therapeutic uses for drugs already approved for other clinical indications. The concept was presented 15 years ago. Initially, the intention was to shorten the pharmaceutical research and development (R&D) process and thereby reduce the costs and risks for the pharmaceutical industry to bring new m...
β-Adrenoceptor Activation in Breast MCF-10A Cells Induces a Pattern of Catechol...
Amaro, Filipa; Silva, Dany; Reguengo, Henrique; Oliveira, José Carlos; Quintas, Clara; Vale, Nuno; Gonçalves, Jorge; Fresco, PaulaAdrenaline, which participates in the neuroendocrine response that occurs during stress and perimenopause, may be tumorigenic. This exploratory study aimed at investigating whether non-tumorigenic and tumorigenic human breast epithelial cell lines are able to synthesize adrenaline. The study was carried out in non-tumorigenic (MCF-10A) and tumorigenic (MCF-7) human breast cell lines. Expression of enzymes invol...
