Anti-inflammatory activity of Croton cuneatus aqueous extract.

The aqueous extract of Croton cuneatus Klotz. (Euphorbiaceae), was tested for its antinociceptive effects using chemical and thermal test models in mice. Anti-inflammatory activity was determined in Sprague-Dawley rats in a model of acute plantar inflammation induced by bovine serum albumin. Croton cuneatus aqueous extract at doses of 7 mg/kg showed a significant anti-inflammatory effect compared with commonly used non-stereoidal drugs as ketoprofen, sodium diclofenac and ASA (acetylsalicylic acid).

New cytotoxic isoflavone from the root bark of Brosimum utile.

A new isoflavone 5,7,4'-trihydroxy-3'-(3-hydroxy-3-methylbutyl)isoflavone (isowigtheone hydrate) (1), together with six known isoflavones 2-7 and (-)epicatechin, were isolated from the root barks of Brosimum utile. Their structures were established on the basis of spectroscopic evidence. The in vitro cytotoxic activity of the new compound 1 was evaluated against cell lines MCF7 (human breast carcinoma), PC3 (human prostate carcinoma), HT29 (human colon cancer) and human dermis fibroblasts.

Three new glutarimide alkaloids from Croton cuneatus.

Analysis of the dichloromethane extract of the aerial parts of Croton cuneatus led to the isolation of the new glutarimide alkaloids: julocrotol (1), isojulocrotol (2), and julocrotone (3) along with the known compounds julocrotonine (4), lichexanthone (5) and selin-11-en-4alpha-ol (6). The structures of the new compounds were established by spectral methods. The in vitro cytotoxic activity of Compounds 1-6 was evaluated against six human tumor cells lines.

Biflavonoids from Podocalyx loranthoides.

Analysis of the ethyl acetate extract of the aerials parts of Podocalyx loranthoides led to the isolation of I 7, II 4'-dimethylamentoflavone (1) and II 4'-methylamentoflavone (2). Compound (1) gave a moderate effect against Leishmania mexicana promastigotes.

Antinociceptive and anti-inflammatory effects of Croton malambo bark aqueous extract.

Croton malambo (K.) bark aqueous extract, popularly known in Venezuela as "palomatias" or "torco" was tested for acute toxicity and for its anti-inflammatory and antinociceptive effects using tail flick and writhing syndrome tests models, respectively. Croton malambo aqueous extract (6.15 mg/kg i.p.) administered intraperitoneally had a significant antinociceptive and anti-inflammatory effects compared to acetylsalicylic acid (200mg/kg p.o.) and sodium diclofenac (5.64 mg/kg p.o.). Studies to determine correlation between chemical composition and pharmacological activity are underway.
