FTY720 increases paclitaxel efficacy in cisplatin-resistant oral squamous cell carcinoma.

Background: Oral squamous cell carcinoma has high recurrence and cisplatin resistance. As cancer stem cells, autophagy, and sphingolipids have been appointed as associated with chemotherapy resistance, we tested combined treatments targeting autophagy and/or sphingolipid metabolism with paclitaxel using cisplatin-resistant oral squamous cell carcinoma cells.

Methods: Cisplatin-resistant oral squamous cell carcinoma cells were maintained under exposition to FTY720 and chloroquine combined with paclitaxel and submitted to viability, clonogenicity, and spheres formation assays.

Topical gel containing phenolic-rich extract from Ipomoea pes-capre leaf (Convolvulaceae) has anti-inflammatory, wound healing, and antiophidic properties.

The growing use of phytotherapy in clinical practice arouses interest in studies using medicinal plants as active ingredients for new medicines. Ipomoea pes-caprae has a wide medicinal use in the treatment of inflammatory disorders, skin wounds, stings, and painful rheumatic processes. Assayed in this study are the physicochemical characterization of a gel developed with this extract and the evaluation of its anti-inflammatory and healing efficacy, in addition to its antiedematogenic action on Bothrops snake envenoming in mice.

availability of metformin hydrochloride-PLGA nanoparticles in diabetic rats in a periodontal disease experimental model.

Context: Metformin is an important oral anti-hyperglycemic used in diabetes. Polylactic-co-glycolic acid (PLGA) has been widely used due to its reliability in controlling the release of drugs.

Objective: This study evaluates the availability of metformin hydrochloride-loaded polylactic-co-glycolic acid.

Hypoglycemic and Vasorelaxant Effect of Passiflora edulis Fruit Peel By-Product.

Passiflora edulis fo. flavicarpa (Passifloraceae) is popularly known as yellow passion fruit and its fruit peels are considered a rich by-product in bioactive compounds which has greatly beneficial health properties. The objective of this study was to evaluate the effects of P.

Mass spectrometry characterization of Commiphora leptophloeos leaf extract and preclinical evaluation of toxicity and anti-inflammatory potential effect.

Ethnopharmacological Relevance: Commiphora leptophloeos (Mart.) J.B.

In Vivo Antidepressant Effect of f. into Cationic Nanoparticles: Improving Bioactivity and Safety.

A variety of neuroactive flavonoids can be found in the species of the genus; however, their difficulty in crossing the blood-brain barrier limits their in vivo neuropharmacological activity. In this study, cationic nanoparticles were developed as a novel nanocarrier for improving the antidepressant activity of f. leaf extract.

Isolation and Identification of the Five Novel Flavonoids from Genipa americana Leaves.

is a medicinal plant popularly known as "jenipapo", which occurs in Brazil and belongs to the Rubiaceae family. It is a species widely distributed in the tropical Central and South America, especially in the Cerrado biome. Their leaves and fruits are used as food and popularly in folk medicine to treat anemias, as an antidiarrheal, and anti-syphilitic.

Phytochemical Analysis by HPLC-HRESI-MS and Anti-Inflammatory Activity of Tabernaemontana catharinensis.

(Apocynaceae) has been popularly used by folk medicine because of its anti-inflammatory, analgesic, and antiophidic properties. This study aims to analyze the flavonoids composition of the hydroethanolic extract and of the ethyl acetate (EtOAc) and butanol (BuOH) fractions of leaves, as well as to evaluate their anti-inflammatory activity using in vivo models. The phytochemical profile, determined by High-Performance Liquid Chromatography-High-Resolution Electrospray Ionization-Mass Spectrometry (HPLC-HRESI-MS), showed the presence of flavonoids mainly having an isorhamnetin nucleus.
