- Abstract:
- ... Cyperenoic acid (1) is one of the major sesquiterpenes isolated from Croton crassifolius, which exhibited potent anti-angiogenic activity. Traditional structural modification of 1 is difficult to perform by chemical technology due to the remarkable stability of the patchoulane skeleton. In order to overcome chemical synthesis difficulties and obtain structurally diverse derivations, microbial tran ...

- Abstract:
- ... Solanum americanum is one of the most prominent species used to treat type 2 diabetes in Guatemala. In our ongoing efforts to find antidiabetic and antioxidative compounds from natural sources, an ethyl acetate extract of this medicinal herb was investigated using dual high-resolution α-glucosidase/radical scavenging inhibition profiling. The high-resolution biochromatograms obtained by this techn ...

A heme-binding assay based on mass spectrometry was performed on P. monodiana Maire (Asteraceae) extracts to identify metabolites able to form adducts with heminic part of haemoglobin, as potential antimalarial drugs. Main adducts were characterized and their stability was measured. Isolation of main constituents of P. monodiana Maire lead to identification of the two methoxyflavones 3′-O-methyleu ...
