Chemical diversity of the herbal decoction of Plectranthus ornatus and its anti-nociceptive and anti-inflammatory activities in zebrafish models.

Ethnopharmacological Relevance: Plectranthus ornatus is a medicinal plant originally from Africa but adapted to Brazil's climate conditions. It is recognized for its therapeutic properties, particularly for treating liver and stomach diseases, gastritis control, heartburn, and hangover. Therefore, studies on its chemical composition and pharmacological evaluation are important for the safe use of the plant.

Robinin Isolated from Solanum asperum Exhibits Pharmacological Actions in the Central Nervous System of Adult Zebrafish (Danio rerio).

This study investigated the anxiolytic, anticonvulsant and memory preservation effects of the flavonoid robinin. The compound, administered at doses of 4, 20 and 40 mg/kg, did not show toxicity after 96 hours of monitoring. In behavioral experiments with zebrafish, robinin did not cause significant changes in motor functions, but it impairs locomotor activity and demonstrates anxiolytic properties, evidenced by the increase in the time spent in the clean zone of the protector.

Anxiolytic and Anticonvulsant Effects of Fisetin Isolated from Bauhinia pentandra on Adult Zebrafish (Danio rerio).

Anxiety and epilepsy are common worldwide and represent a primary global health concern. Fisetin, a flavonoid isolated from Bauhinia pentandra, has a wide range of biological activities may be a promising alternative to combat diseases related to the central nervous system (CNS). The present study aimed to investigate the anxiolytic and anticonvulsant effects of fisetin on adult zebrafish.

Further Polycyclic Quinones of Micromonospora sp.

The crude acetone extract of a marine Micromonospora sp. strain associated with Eudistoma vannnamei was fractioned with hexane and ethyl acetate. The crude extract and both soluble fractions were assayed against several bacteria strains.

Campesterol Semi-Synthetic Derivatives as Potential Antibacterial: in vitro and in silico Evaluation.

In this study, twelve campesterol derivatives (2-13) were prepared by esterification reaction at the hydroxy group in C-3 and catalytic hydrogenation at the carbon-carbon double bond in C-5(6). All obtained compounds were characterized by IR, H-NMR, C-NMR, and MS spectra. Campesterol (1) and its derivatives (2-13) were evaluated in vitro against Staphylococcus aureus (ATCC 6538), Streptococcus mutans (ATCC 0046), Escherichia coli (ATCC 10536), Pseudomonas aeruginosa (ATCC 15442), and Klebsiella pneumoniae (ATCC 10031) using the microdilution method.

Chromomycin A induces bona fide immunogenic cell death in melanoma.

Purpose: Some first-line cytotoxic chemotherapics, doxorubicin, paclitaxel and oxaliplatin, induce activation of the immune system through immunogenic cell death (ICD). Tumor cells undergoing ICD function as a vaccine, releasing damage-associated molecular patterns (DAMPs), which act as adjuvants, and neoantigens of the tumor are recognized as antigens. ICD induction is rare, however it yields better and long-lasting antitumor responses to chemotherapy.

Hypoglycemic and hepatoprotective effects in adult zebrafish () of fisetinidol isolated from : and assays.

Diabetes mellitus is a chronic metabolic disorder that has been increasing drastically around the worldwide. It is important to emphasize that although many drugs are commercially available to treat diabetes, many of them have shown a number of adverse effects. Therefore, search for new antidiabetic agents is of great interest, and natural products, especially those obtained from plants sources, may be an alternative to available drugs.

Supplementation of in vitro culture medium with FSH to grow follicles and mature oocytes can be replaced by extracts of Justicia insularis.

The present study evaluated the effect of supplementing in vitro culture medium with J. insularis compared to FSH on isolated secondary follicles and in vitro maturation of oocytes from those follicles. Secondary follicles were isolated from sheep ovaries and individually cultured for 18 days in α-MEM+ (Control), α-MEM+ supplemented with 100 ng/mL recombinant bovine follicle stimulating hormone (FSH) or with 0.

Standardized extract of Erythrina velutina Willd. attenuates schizophrenia-Like behaviours and oxidative parameters in experimental animal models.

Objectives: To study the effects of the standardized extract from the leaves of Erythrina velutina in behavioural and oxidative parameters in the ketamine-induced schizophrenia model.

Methods: Mice received ketamine (KET) or saline for 7 days. From 8th to 14th day, the animals received Erythrine (Eryt) (100, 200 or 400 mg/kg) or olanzapine (Olanz), 1 h after KET administration.
