Physalins B, F and G, seco-steroids purified from Physalis angulata L., inhibit lymphocyte function and allogeneic transplant rejection.
Physalis angulata is a solanaceae widely used in folk medicine in various tropical countries in the world. We have previously described that seco-steroids (physalins) purified from P. angulata are potent inhibitors of macrophage activation, blocking the production of pro-inflammatory cytokines and LPS-induced lethality. Herein we investigated the immunomodulatory activities of these substances ...
متن کاملPhysalins B and F, seco-steroids isolated from Physalis angulata L., strongly inhibit proliferation, ultrastructure and infectivity of Trypanosoma cruzi.
We previously observed that physalins have immunomodulatory properties, as well as antileishmanial and antiplasmodial activities. Here, we investigated the anti-Trypanosoma cruzi activity of physalins B, D, F and G. We found that physalins B and F were the most potent compounds against trypomastigote and epimastigote forms of T. cruzi. Electron microscopy of trypomastigotes incubated with physa...
متن کاملCytotoxic withanolides from Vietnamese ethno-medicinal plant Physalis angulata
Withanolides are known as the main components of Physalis genus with broad biological activities. Using combination of various chromatographic methods, three withanolides were isolated including physagulin J (1), physagulin K (2), and physagulin N (3). Their chemical structures were determined by analysis of NMR spectra, and as well as comparison with reported literature. Compound 1 showed sign...
متن کاملWithanolides from Physalis hispida.
Nine new withanolides (1-9), withahisolides A-I, were isolated along with nine known compounds (10-18) from the aerial parts of Physalis hispida. The structures of 1-9 were elucidated through a variety of spectroscopic techniques, while the structures of 1 and 2 were confirmed by X-ray crystallographic analysis. Compounds 1-3 are the first withanolides with nonaromatic six-membered ring D moiet...
متن کاملWithanolides from Physalis coztomatl.
Six withanolides (1-6), as well as two known withanolides (physachenolide D 7 and withanoside VI 8), were isolated from the aerial parts of Physalis coztomatl (Solanaceae). Structural elucidations of 1-6 were achieved through 2D NMR and other spectroscopic techniques, while the structure of 1 was confirmed by X-ray crystallographic analysis. In addition, the stereochemical orientation of the 17...
