Kubec R, Musah RA.
Department of Chemistry, State University of New York at Albany , NY , Albany 12222 , USA .

Two diastereomers of S-benzyl-L- cysteine sulfoxide have been isolated from fresh roots of Petiveria alliacea . Their structures and absolute configurations have been determined by NMR, MALDI-HRMS, IR and CD spectroscopy and confirmed by comparison with authentic compounds. Both the R(S) and S(S) diastereomers of the sulfoxide are present in all parts of the plant (root, stem, and leaves) with the latter diastereomer being predominant. Their total content greatly varied in different parts of the plant between 0.07 and 2.97 mg g( -1) fr . wt, being by far the highest in the root. S- Benzylcysteine has also been detected in trace amounts (<10 microg g( -1) fr . wt) in all parts of the plant. This represents the first report of the presence of S- benzylcysteine derivatives in nature.

Dibenzyl trisulphide (DTS), a main lipophilic compound in Petiveria alliacea L. ( Phytolaccaceae ), was identified as one of the active immunomodulatory compounds in extracts of the plant. To learn more about its biological activities and molecular mechanisms, we conducted one-dimensional NMR interaction studies with bovine serum albumin (BSA) and tested DTS and related compounds in two well-established neuronal cell-and-tissue culture systems. We found that DTS preferentially binds to an aromatic region of BSA which is rich in tyrosyl residues. In SH-SY5Y neuroblastoma cells, DTS attenuates the dephosphorylation of tyrosyl residues of MAP kinase (erk1/erk2). In the same neuroblastoma cell line and in Wistar 38 human lung fibroblasts, DTS causes a reversible disassembly of microtubules, but it did not affect actin dynamics. Probably due to the disruption of the microtubule dynamics, DTS also inhibits neuroblastoma cell proliferation and neurite outgrowth from spinal cord explants. Related dibenzyl compounds with none, one, or two sulphur atoms were found to be significantly less effective. These data confirmed that the natural compound DTS has a diverse spectrum of biological properties, including cytostatic and neurotoxic actions in addition to immunomodulatory activities.

Non-physiological inducers of terminal differentiation have been used as novel therapies for the prevention and therapy of cancer. We have used cultured HL-60 promyelocytic cells to monitor differentiation, proliferation and cell death events as induced by a large set of extracts derived from plants. Screening of more than 1400 extracts led to the discovery of 34 with potent activity (ED50 <8 mg/ml). Bioassay-guided fractionation led to the isolation of zapotin and 2' ,5,6 -trimethoxyflavone as active principles from Casimiroa edulis , dibenzyltrisulfide and 2-[( phenylmethyl ) dithio ]ethanol as active principles from Petiveria alliacea , and desmethylrocaglamide from Aglaia ponapensis . Zapotin demonstrated the most favorable biological profile in that induction of differentiation correlated with proliferation arrest, and a lack of cytotoxicity . We conclude that the HL-60 cell model is a useful system for the discovery of novel pharmacophores with potential to suppress the process of carcinogenesis, and that flavonoids may be especially useful in this capacity.

In this work, we investigated the effects of Petiveria alliacea extract on the production of Th1-type and Th2-type cytokines and on NK cells activity in normal and Listeria monocytogenes infected mice. Our results demonstrated that in normal/non-infected mice P. alliacea administration led to increased levels of Interleukin-2 (IL-2). The infection alone enhanced INF-gamma levels and NK cell activity at 48 and 72 hours of infection. The treatment with five consecutive doses of 1000 mg/kg/day of P. alliacea extract, given previously to infection, led to further increases in IL-2 levels, in relation to normal/non-infected/P. alliacea treated controls, and in INF-gamma levels at 72 h of infection, compared to infected mice. On the other hand, the production of IL-4 and IL-10 were not altered either by the infection or by the treatment with P. alliacea extract. NK cells activity increased at 48 h and 72 h following the inoculation of the bacteria. When mice were treated with P. alliacea previously to infection, NK activity was higher than that observed at 48 h, 72 h and 120 h of infection in the infected animal. Based on these findings we suggest that P. alliacea up-regulates anti-bacterial immune response by enhancing both Th1 function and the activity of NK cells.

Department of Physiology, Institute of Biology, State University of Campinas (UNICAMP), SP, Brazil.

In this study we have investigated the effects of Petiveria alliacea on the hematopoietic response of mice infected with Listeria monocytogenes . Our results demonstrate a protective effect of the crude extract of P. alliacea since the survival of the treated/infected was higher than that in the infected group. Moreover, the number of granulocyte/macrophage colonies (CFU-GM) and the serum colony stimulating activity levels were increased in the treated/infected mice in relation to the infected group. These results suggest an immunomodulation of Petiveria alliacea extract on hematopoiesis , which may be responsible, at least in part, for the increased resistance of mice to Listeria monocytogenes infection.

Extracts were prepared from 13 native plants used for the treatment of protozoal infections. Activity against bacteria and fungi was demonstrated by dilution procedures; Trypanosoma cruzi was evaluated in vitro against epimastigote and trypomastigotes and in vivo against trypomastigotes . In active extracts, toxicity was evaluated by Artemia salina nauplii , oral acute toxicity (1-5 g/kg) and oral and intraperitoneal subacute toxicity in mice (500 mg/kg). From the plants screened, six showed activity (< or = 2 mg/ml) against bacteria, three against yeasts, five against Microsporum gypseum and five against T. cruzi in vitro and/or in vivo. In vitro and in vivo activity was demonstrated by Neurolaena lobata and Solanum americanum ; in vitro or in vivo activity was shown by Acalypha guatemalensis , Petiveria alliacea and Tridax procumbens . Toxicity studies showed that extracts from S. americanum are toxic to A. salina (aqueous, 160 ppm ). None showed acute or oral toxicity to mice; S. americanum showed intraperitoneal subacute toxicity.

The activities of crude plant extracts of five plants popularly used in Guatemala against bacterial and protozoal infections and some of their fractions have been evaluated against the trypomastigote and epimastigote forms of Trypanosoma cruzi in vitro. The most active fraction of Neurolaena lobata has also been screened in vivo. Main in vitro activities against trypomastigotes have been observed for the hexane and ethanol extracts of N. lobata ( Asteraceae ). Both extracts were also active against epimastigotes , whereas all other extracts tested had no effect on epimastigotes . For the hexane extracts of Petiveria alliacea ( Phytolaccaceae ) and Tridax procumbens ( Asteraceae ) a marked inhibition of trypomastigotes has been found. Also the ethanol extracts of Byrsonima crassifolia ( Malpighiaceae ) leafs and Gliricidia sepium ( Papilionaceae ) bark showed some trypanocidal activity. Fraction 2 of the ethanol extract of N. lobata was highly active against T. cruzi as well in vitro as in vivo. The chloroforme fraction of P. alliacea showed a high inhibition of trypomastigotes in vitro. Also three fractions of the active extract of B. crassifolia inhibited T. cruzi trypomastigotes . No fraction of G. sepium bark extract showed a marked trypanocidal activity.

Departamento de Fisiologia Geral , Universidade de Sao Paulo, Brasil .

The hydroethanol extract of the roots of Petiveria alliacea L. ( Phytolaccaceae ) has been investigated previously as an antitumor agent against mouse Ehrlich ascites . The extract and its methanol, butanol and ether fractions exhibited an antimitotic effect on sea urchin egg development. The aqueous fraction did not produce inhibition of cell cleavage. At the first cleavage the inhibition, at the lowest concentration (10 micrograms/ml), produced by the ether fraction was 42%, whereas the inhibition produced by the total extract and by the other fractions was only 5 to 10% showing that the ether fraction was the most active. Even at higher concentrations the butanol and methanol fractions inhibit the cleavage about 30%. At the first cleavage, the ED50 of the hydroethanol extract and of the ether fraction were 45.02 and 12.40 micrograms/ml, respectively. Furthermore, in the second cleavage, the hydroethanol extract was about twice as potent as the methanol or butanol fractions (ED50 of 22.40, 44.80 and 54.10 micrograms/ml, respectively).

Center for Mesoamerican Studies on Appropriate Technology (CEMAT), Guatemala City .

An ethnobotanical survey was conducted among the Carib population of Guatemala in 1988- 1989. In general terms, the sample surveyed possessed a relatively good standard of living. Results indicated that health services were utilized by the population, and that domestic medicine, mainly plants (96.9%) was used by 15% of the population. One hundred and nineteen plants used for medicinal purposes were collected, of which 102 (85.7%) could be identified; a list of these together with the information provided for each plant is presented. The most frequently reported plants used as medicine are: Acalypha arvensis , Cassia alata , Cymbopogon citratus , Melampodium divaricatum . Momordica charantia , Neurolaena lobata , Ocimum basilicum , Petiveria alliacea and Solanum nigrescens . Most of these plants are found in the region, but some are brought from the Highlands or outside of the country, such as Malva parviflora , Matricaria chamomilla , Peumus boldus , Pimpinella anisum , Rosmarinus officinalis and Tagetes lucida . This survey demonstrated that the Carib population of Guatemala has survived in a transcultural environment of African and native Amerindian beliefs

Escola Paulista de Medicina, Sao Paulo, Brasil.

Osteoarthritis (OA) is a common painful inflammatory condition occurring mainly in the later half of life. Hip and knee are the joints mostly affected. Petiveria alliacea (tipi) popularly known as an anti-rheumatic medicine, has been used by OA patients to relief pain. This one-week cross-over double-blind trial has preliminary evaluated the analgesic effect of tipi tea in 14 patients with hip and knee OA. Imperata exaltata ( sape ) was used as the Placebo tea. The pain assessments that were made at baseline and before the start of the second treatment period by treatment groups were comparable. While taking tipi or placebo tea patients experienced a statistically significant improvement in pain on motion and pain at night. The comparison between the improvements reported while on tipi and placebo tea, however, did not disclose any statistically significant difference. At the conclusion of the study 7 patients preferred tipi tea and 6 preferred placebo tea (NS). Two patients reported insomnia, one during placebo treatment and the other during tipi treatment.

Evaluation of antinociceptive effect of Petiveria alliacea ( Guine ) in animals.

de Lima TC, Morato GS, Takahashi RN.
Departamento de Farmacologia , Universidade Federal de Santa Catarina, Florianopolis , Brasil.

Petiveria alliacea ( Phytolaccaceae ) is a bush widely distributed in South America including Brazil , where it is popularly known as " guine ", " pipi ", "tipi" or " erva -de-tipi". Brazilian folk medicine attributes to the hot water infusion of its roots or leaves the following pharmacological properties: antipyretic, antispasmodic, abortifacient , antirrheumatic , diuretic, analgesic and sedative. The present study has evaluated the alleged effects of P. alliacea on central nervous system (CNS), particularly, the sedative and analgesic properties of root crude aqueous extract of this plant in mice and rats. This extract showed an antinociceptive effect in acetic acid--acetylcholine--and hypertonic saline--induced abdominal constrictions, but not in hot-plate and tail flick tests. P. alliacea did not produce any CNS depressor effect. Thus its antinociceptive action in animals can be responsible by its popular use as an analgesic.
