Wounds represent a medical problem that contributes importantly to patient morbidity and to healthcare costs in several pathologies. In Hidalgo, Mexico, the Bacopa procumbens plant has been traditionally used for wound-healing care for several generations; in vitro and in vivo experiments were designed to evaluate the effects of bioactive compounds obtained from a B. procumbens aqueous fraction and to determine the key pathways involved in wound regeneration. Bioactive compounds were characterized by HPLC/QTOF-MS, and proliferation, migration, adhesion, and differentiation studies were conducted on NIH/3T3 fibroblasts. Polyphenolic compounds from Bacopa procumbens (PB) regulated proliferation and cell adhesion; enhanced migration, reducing the artificial scratch area; and modulated cell differentiation. PB compounds were included in a hydrogel for topical administration in a rat excision wound model. Histological, histochemical, and mechanical analyses showed that PB treatment accelerates wound closure in at least 48 h and reduces inflammation, increasing cell proliferation and deposition and organization of collagen at earlier times. These changes resulted in the formation of a scar with better tensile properties. Immunohistochemistry and RT-PCR molecular analyses demonstrated that treatment induces (i) overexpression of transforming growth factor beta (TGF-β) and (ii) the phosphorylation of Smad2/3 and ERK1/2, suggesting the central role of some PB compounds to enhance wound healing, modulating TGF-β activation.

Background/Objectives: Antimicrobial resistance represents a critical global health challenge that has been exacerbated by the significant decline in antibiotic development. Natural product-based drugs, particularly plant-derived phenolic compounds, offer promising alternatives to conventional antibiotics. This study aimed to isolate and characterize a novel phenolic compound from Bacopa procumbens, a Mexican perennial repent plant that is widespread in the Mexican valley and produces a variety of saponins, gastrodin derivatives, and phenolic acids, and to evaluate its antibacterial potential against clinically relevant pathogens. Methods: The hydroalcoholic extraction of B. procumbens was followed by liquid–liquid partitioning with ethyl acetate. The resulting fraction underwent chromatographic separation and purification. The structural elucidation of the isolated compound was performed using thin-layer chromatography (TLC), high-performance liquid chromatography (HPLC), mass spectrometry (MS-EI), and nuclear magnetic resonance (NMR) techniques. Antimicrobial activity was assessed via a microdilution assay against five bacterial strains, including drug-resistant Staphylococcus species and Gram-negative pathogens. Results: A novel phenolic compound, 5-(p-hydroxybenzoyl) shikimic acid (5pHSA), was isolated and characterized. The compound demonstrated moderate antibacterial activity against methicillin-resistant Staphylococcus haemolyticus and Escherichia coli (minimum inhibitory concentration (MIC) = 100 μg/mL) but showed limited efficacy against Staphylococcus aureus, MRSA, and Klebsiella pneumoniae (MIC > 100 μg/mL). Comparative analysis with the previously isolated compound ProcumGastrodin A revealed structure–activity relationships where the higher lipophilicity of PG-A was correlated with enhanced antimicrobial activity. Conclusions: This study establishes 5pHSA as a novel phenolic compound with moderate antibacterial properties. The findings highlight the importance of molecular polarity and structural complexity in determining antimicrobial efficacy, offering valuable insights into the development of phenolic, acid-based antimicrobial agents to address the growing challenge of antimicrobial resistance.
Background: Bacopa procumbens is a plant species with medicinal properties. Although several of these properties have already been validated, its use for treating pain remains untested. Objective: the objective was therefore to test the antinociceptive effect of two extracts (n-hexane and hydroalcoholic) and two fractions (aqueous and organic) from the most active extract, as well as to determine the chemical profile of Bacopa procumbens. Methods: analgesic activity was determined by antinociceptive activity using the formalin model in mice. Compounds were identified by high-performance liquid chromatography and gas chromatography coupled with mass spectrometry. Compared to the vehicle treatment (3% Tween 20), licking time was 22.8 s and 141.6 s lower when treated with the hexane extract (200 mg/kg); 43.4 s and 152.5 s with the hydroalcoholic extract (200 mg/kg); 27.2 s and 169 s with the organic fraction; and 5.4 s and 32 s difference with the positive control, in phases 1 and 2, respectively. Phytochemical analysis of the hexane extract allowed us to identify 2-pentadecanone, 6,10,14-trimetil- (11.70%), 6,10,14-trimethyl-, dibutyl phthalate (34.71%), and hexane-dioic acid bis(2-ethylhexyl) ester (45.15%). Conclusions: We identified arbutin (1), 5-(p-hydroxybenzoyl) shikimic acid (2), and procumgastrodin A (3) in the BpFo fraction. In conclusion, we demonstrated that the BpH extract and the BpFo fraction have anti-nociceptive properties that may be associated with compounds 2 and 3.

Objetivo: Identificar el conocimiento sobre el uso tradicional de Bacopa procumbens que conservan los pobladores del municipio de Huasca de Ocampo, Hidalgo, México. Metodología: El estudio se basó en una entrevista estructurada aplicada a 26 informantes, mediante un muestreo por conveniencia. Se realizó el análisis descriptivo de la información por medio de frecuencias y un análisis multivariado de correspondencias múltiples. Resultados: El conocimiento tradicional de esta planta se concentra en las amas de casa con edad entre 40 y 50 años; este conocimiento fue trasmitido por familiares, el uso tradicional que le dan a la especie B. procumbens es medicinal y se usa para disminuir o aliviar el dolor de estómago, sanar heridas, calmar el dolor de muelas, calmar el dolor de riñón, eliminar la hinchazón y fiebre. La planta es recolectada en el campo, solo en la cantidad que será usada, lo que puede ayudar en parte a la conservación del recurso, aunque debe prevenirse la sobre explotación. Limitaciones: Existen pocas personas que conocen la planta y sus propiedades. Conclusiones: El conocimiento tradicional de la planta se centra en mujeres amas de casa, la forma más común de uso es hervida y se aplica principalmente para dolor de estómago, y otros problemas de salud.
Carminic acid is a natural pigment typically found in several insect taxa, including specific insects such as “grana cochinilla fina” in Mexico (Dactylopius coccus Costa). Commercially, it is also referred to as carmine, which is a more concentrated solution presenting as at least 50% carminic acid. To date, this dye has been used in the pharmaceutical, food and cosmetic industries. Unfortunately, one of the main limitations has to do with establishing the appropriate extraction and purification protocol. Currently, there is growing interest in developing eco-friendly and efficient pigment extraction processes for various applications. In this study, we compare the ultrasound- and microwave-assisted extraction versus with a conventional method to obtain carminic acid from cochineal. To do this, we considered three factors that influence the extraction process as independent variables: solvent volume, temperature and irradiation time. The optimization was carried out using the response surface methodology, employing a three-factor and three-level Box–Behnken experimental design. Carminic acid contents were quantified by UV–Vis spectroscopy, and extracts were evaluated by infrared spectroscopy to verify the integrity of the carminic acid molecule. The yield obtained by ultrasound-assisted extraction was 49.2 ± 3.25, with an efficiency of 31.3 mg/min, while microwave-assisted extraction showed a yield of 40.89 ± 2.96, with an efficiency of 27.3 mg/min. Both methods exceeded the extract yield (31.9 ± 3.4%) and efficiency (10.6 mg/min) obtained with the conventional method, demostrating that ultrasound- and microwave-assisted extraction are viable alternatives for obtaining carminic acid, with the potential to be scaled up to an industrial level.
