Inhibition of macrophage activation and lipopolysaccaride-induced death by seco-steroids purified from Physalis angulata L.
Milena Botelho Pereira Soares,Moema C. Bellintani,Ivone Maria Ribeiro,Therezinha C. B. Tomassini,Ricardo Ribeiro dos Santos +4 more
TL;DR: Results demonstrate that seco-steroids from P. angulata are potent immunomodulatory substances and act through a mechanism distinct from that of dexamethasone.

In vitro and in vivo antiparasitic activity of Physalis angulata L. concentrated ethanolic extract against Trypanosoma cruzi.
Cássio Santana Meira,Elisalva Teixeira Guimarães,Jamyle Andrade Ferreira dos Santos,Diogo Rodrigo Magalhães Moreira,Renata Campos Nogueira,Therezinha C. B. Tomassini,Ivone Maria Ribeiro,Claudia de Souza,Ricardo Ribeiro dos Santos,Milena Botelho Pereira Soares,Milena Botelho Pereira Soares +10 more
TL;DR: EEPA has antiparasitic activity against T. cruzi, causing cell death by necrosis and showing synergistic activity with benznidazole.

Molluscicidal activity of Physalis angulata L. extracts and fractions on Biomphalaria tenagophila (d'Orbigny, 1835) under laboratory conditions
José Augusto Albuquerque dos Santos,Therezinha C. B. Tomassini,Deise Cristina Drummond Xavier,Ivone Maria Ribeiro,Melissa Teixeira G da Silva,Zenildo Buarque de Morais Filho +5 more
TL;DR: Evaluated molluscicide activity of Biomphalaria tenagophila specimens under laboratory conditions show that ethyl acetate and acetone extracts from the whole plant, the ethanolic extracts of the roots and the physalins pool from stems and leaves were active.
Gênero Physalis - uma revisão sobre vitaesteróides
Therezinha C. B. Tomassini,Nancy S. Barbi,Ivone Maria Ribeiro,Deise Cristina Drummond Xavier +3 more
TL;DR: Results on the chemistry and spectroscopic data of some ergostane derivatives named withasteroids which have been obtained from Physalis genus are described, which appear to be a source for new drugs to be apply as medicine.
Physalin F, a seco-steroid from Physalis angulata L., has immunosuppressive activity in peripheral blood mononuclear cells from patients with HTLV1-associated myelopathy.
Lorena A. Pinto,Cássio Santana Meira,Cristiane Flora Villarreal,Cristiane Flora Villarreal,Marcos A. Vannier-Santos,Claudia de Souza,Ivone Maria Ribeiro,Therezinha C. B. Tomassini,Bernardo Galvão-Castro,Milena Botelho Pereira Soares,Milena Botelho Pereira Soares,Maria Fernanda Rios Grassi +11 more
TL;DR: Transfer electron microscopy analysis of PBMC showed that physalin F induced ultrastructural changes, such as pyknotic nuclei, damaged mitochondria, enhanced autophagic vacuole formation, and the presence of myelin-like figures, decreasing the spontaneous proliferation and cytokine production caused by HTLV-1 infection.
