Herbalists, traditional healers and pharmacists: a view of the tuberculosis in Ghana
This paper is the result of a visit by Brazilian researchers to Ghana, with the aim of improving understanding of the relationship between traditional healers and conventional health practices, specifically in relation to tuberculosis. Through this exploratory visit, this group of researchers promoted by the Edital Pro Africa (CNPq) had an opportunity to learn about, reflect on, and discuss the different social, economic and cultural realities and contexts that have led to the different health conditions and forms of healthcare in Ghana. Besides the direct relationship between the social and economic conditions of the country and the health of its population, it was also concluded that ther…
ESI-MS2and Anti-inflammatory Studies of Cyclopropanic Triterpenes. UPLC-ESI-MS and MS2Search of Related Metabolites fromDonella ubanguiensis
Introduction Triterpenes are one of the largest secondary metabolites groups spread in the plant kingdom with various skeletons. These metabolites have showed various bioactivities including anti-inflammatory activity. Objective The study aims to explore the mass spectrometry fragmentation of donellanic acids A-C (DA A–C), three compounds identified from Donella ubanguiensis; in addition, the fragmentation behaviour of these metabolites will serve as a fingerprint to search and characterise triterpenes congeners in fruits, bark and wood crude extracts of D. ubanguiensis. This work was prompted by the anti-inflammatory activity on leukocyte migration, exudate concentrations and myeloperoxida…
Prospecting for cytotoxic and antiprotozoal 4-aryl-4H-chromenes and 10-aryldihydropyrano[2,3-f]chromenes.
Different studies reported that genetic predisposition or metabolic dysfunction are the risk factors for cancer. Infectious parasitic diseases were listed among factors that predispose to cancer. Because of the resemblance between the life cycle of cancer cells and some parasites, this study aimed to prepare pyran derivatives with cytotoxic and antiprotozoal potencies. Therefore, 7 chromenes, 10 pyranocoumarins, and an unexpected intermediate were obtained from a multi-reagent one-pot reaction. These compounds were evaluated for their cytotoxicity on sensitive and resistant leukemia cancer cells lines and against two protozoan parasites, namely Trypanosoma cruzi and Leishmania amazonensis a…
