Abstract Background Sterols are structural and functional components of eukaryotic cell membranes. Plants produce a complex mixture sterols, among which β-sitosterol, stigmasterol, campesterol, cholesterol in some Solanaceae, the most abundant species. Many reports have shown that stigmasterol to β-sitosterol ratio changes during plant development response stresses, suggesting it may play role ...

hiv-1 integrase (in) enzyme, one of the three main enzymes of hiv-1, catalyzed the insertion of the viral dna into the genome of host cells. because of the lack of its homologue in human cells and its essential role in hiv-1 replication, in inhibition represents an attractive therapeutic target for hiv-1 treatment. since identification of in as a promising therapeutic target, a major progress h...
