1 4 naphthoquinone/edema

2-Chloro-3-methoxycarbonylpropionamido-1,4-naphthoquinone (PP1D1) produced a dose-dependent inhibition of the polymyxin B-induced hind-paw edema in normal as well as in adrenalectomized mice. A comparable inhibitory profile was observed in mice to which PP1D1 was injected i.p. or applied orally.

Chemical investigation of the tubers of Sinningia reitzii led to the isolation of five new naphthoquinones, 8-hydroxydehydrodunnione (1), 7-hydroxydehydrodunnione (2), 5-hydroxy-6,7-dimethoxy-α-dunnione (3), 5-hydroxy-6,7-dimethoxydunniol (4), and 8-hydroxy-7-methoxy-2-O-methylstreptocarpone (5).

Extracellular ATP activates purinergic receptors such as P2X7, cationic channels for Ca²⁺, K⁺, and Na⁺. There is robust evidence of the involvement of these receptors in the immune response, so P2X7 receptors (P2X7R) are considered a potential therapeutic target for

beta-Lapachone, a 1,2-naphthoquinone, is a novel chemotherapeutic agent. It has been shown to be capable of suppressing inducible nitric oxide synthase expression and function in rat alveolar macrophages. The authors further performed experiments to examine the molecular mechanism of beta-lapachone

P2X7 receptor (P2X7R) is an ATP-gated ion-channel with potential therapeutic applications. In this study, we prepared and searched a series of 1,4-naphthoquinones derivatives to evaluate their antagonistic effect on both human and murine P2X7 receptors. We explored the structure-activity

Aethiopinone (1), an o-naphthoquinone diterpene from Salvia aethiopis L. roots and two hemisynthetic derivatives 2 and 3 have been evaluated for toxicity, anti-inflammatory, analgesic, antipyretic, and haemostatic activities. The compounds tested showed low toxicity and a pharmacological profile

Acetylshikonin, a naphthoquinone isolated from the Chinese herb medicine, tzu ts'ao, was demonstrated to inhibit the polymyxin B-induced hind-paw edema in normal as well as in adrenalectomized mice. Liver glycogen content was increased in adrenalectomized mice pretreated with dexamethasone, but not

We previously showed that plants from the genus Sinningia are a source of antiinflammatory and analgesic compounds with different mechanisms of action. The present study evaluated the antiinflammatory, antinociceptive, and antipyretic effects of a crude extract (CE) from Sinningia canescens, its

BACKGROUND Cnidoscolus quercifolius is a species popularly known as favela and faveleira, and belonging to the Caatinga biome (semi-arid vegetation, Brazil), where is used in folk medicine as an anti-inflammatory. OBJECTIVE The aim was to evaluate the anti-inflammatory effect of the ethanolic

BACKGROUND We describe a child and an adult infected with the human immunodeficiency virus (HIV) who developed cerebral lesions consistent with toxoplasmosis. A biopsy in the child and IgG ELISA in both patients confirmed the diagnosis of Toxoplasma gondii. The patients were initially treated with

Plumbago zeylanica Linn. (Plumbaginaceae) is used in the treatment of various inflammatory ailments in traditional medicines. In order to validate these ethnobotanical practices, the anti-inflammatory and antinociceptive activities of various leaf extracts (petroleum ether (60-80 degrees ),

Complex regional pain syndrome (CRPS) is the complication of some injuries, such as a fracture, which affects the distal end of the injured extremity characterized by pain, allodynia, hyperalgesia, edema, abnormal vasomotor and sudomotor activity, movement disorders, joint stiffness, regional

On the basis of previous observations that both 2,3-dihydro-2,2,3,3-tetrahydroxy-1,4-naphthoquinone (oxoline, 1) and 6-chloroisonaphthazarin (2) had demonstrated antipsoriatic activity in vivo, a series of structural derivatives of 2 were prepared and examined in the Scholtz-Dumas topical psoriasis
