Abstract
Background:
Passiflora L. is a genus belonging to the Passifloraceae family, with many species widely used in folk medicine and several pharmacological activities described in the scientific literature, being a major target for the development of new therapeutic products. Studies have identified several bioactive compounds in their composition as responsible for these activities, mainly C-glycoside flavonoids.
Objective:
The aim of this study was carry out a review of patents related to the genus and its application in several pharmacological activities, important for the development of new drugs and formulations.
Method:
The search was carried out in 5 specialized databases, INPI, EPO, WIPO, Latipat and Derwent, using the term ‘Passiflora’ combined with ‘A61K and A61P', subclasses of the section A, of the International Patent Classification (IPC), which are destined to medical, dental or hygienic purposes, and therapeutic activity of chemical compounds or medicinal preparation, respectively.
Results:
1,198 patents, citing the genus in the title or abstract, have been found, 508 being duplicates. After exclusion and inclusion criteria, 23 patents written in English, Portuguese and Spanish were selected, which demonstrated biological assays in vivo with species of Passiflora as the only active constituent or incorporated in formulations with other compounds.
Conclusion:
The findings of this search showed growing interest in research and industrial areas, in the pharmaceutical development with species of Passiflora, suggesting that the different bioactive compounds present in the genus can be considered as an important tool for the development of new effective and safe products with pharmacological potential.

Abstract
ETHNOPHARMACOLOGY RELEVANCE Schinus terebinthifolia Raddi leaves have been used in folk medicine due to several properties, including antitumor and analgesic effects. The variable efficacy and adverse effects of analgesic drugs have motivated the search for novel antinociceptive agents. It has been reported that the S. terebinthifolia leaf lectin (SteLL) has antitumor activity against sarcoma 180 in mice. AIM OF THE STUDY This work aimed to evaluate whether SteLL would reduce cancer pain using an orthotopic tumor model. MATERIALS AND METHODS A sarcoma 180 cell suspension was inoculated into the right hind paws of mice, and the treatments (150 mM NaCl, negative control; 10 mg/kg morphine, positive control; or SteLL at 1 and 2 mg/kg) were administered intraperitoneally 24 h after cell inoculation up to 14 days. Spontaneous nociception, mechanical hyperalgesia, and hot-plate tests were performed. Further, the volume and weight of the tumor-bearing paws were measured. RESULTS SteLL (2 mg/kg) improved limb use during ambulation. The lectin (1 and 2 mg/kg) also inhibited mechanical hyperalgesia and increased the latency time during the hot-plate test. Naloxone was found to reverse this effect, indicating the involvement of opioid receptors. The tumor-bearing paws of mice treated with SteLL exhibited lower volume and weight. CONCLUSION SteLL reduced hyperalgesia due to sarcoma 180 in the paws of mice, and this effect can be related to its antitumor action.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Schinus terebinthifolia Raddi is a plant broadly used in folk medicine and the use of its leaf extract as an antitumor agent has been reported. AIM OF THE STUDY To evaluate the antitumor potential and the toxicity of saline extract (SE) and lectin (SteLL) from S. terebinthifolia leaves in sarcoma 180-bearing mice. MATERIALS AND METHODS Cytotoxicity to sarcoma 180 cells was tested in vitro, and antitumor assay was performed using Swiss female mice. The treatments (0.15 M NaCl, negative control; methotrexate 1.5 mg/kg, positive control; SE 100 mg/kg; SteLL 1 and 5 mg/kg) by intraperitoneal injections started on the 8th day after tumor inoculation and lasted 7 days. It was analyzed: tumor weight; number and gauge of tumor vessels; hematological and biochemical parameters; histopathological changes; and occurrence of micronuclei in bone marrow cells. RESULTS SE and SteLL showed IC50 values (concentrations that reduced cell viability to 50%) of 301.65 and 8.30 μg/mL, respectively. The lectin was able to induce apoptosis. Treatments with the extract and lectin caused a 57.6-73.6% reduction in tumor weight, which was not significantly different from the reduction in the methotrexate group. Tumors of animals treated with SteLL at 5 mg/kg showed reduced number of secondary vessels while the gauge was lower in all treated groups. In the groups treated with SteLL, tumors showed reduced and slightly vascularized parenchyma, with necrosis in the center and at the periphery. No alterations in the blood levels of urea, creatine, and glucose were detected while serum AST level was moderately increased in the SE group. Histopathological analysis revealed vacuolization and steatosis in the liver of animals treated with the extract and lectin. In addition, the treatments with SE and SteLL resulted in the reduction of filtration space and alterations in tubular architecture in kidneys. In respect to hematological parameters, it was only detected increase in the number of monocytes in SE group. The extract and lectin did not induce the formation of micronuclei in the bone marrow cells. CONCLUSIONS SE and SteLL had antitumor effect against sarcoma 180 without inducing hematological changes and genotoxic effects in mice; however, some degree of hepatic and renal toxicity was observed, suggesting the evaluation of drug delivery strategies in the future.
