Benzopyrans from Melicope ptelefolia leaves

, : Benzopyrans from Melicope ptelefolia leaves. Phytochemistry (Oxford) 45(5): 1049-1056

Investigation of leaves of Melicope ptelefolia afforded 18 2,2-dimethyl-2H-1-benzopyrans, consisting of 14 new members, including one benzodipyran and four known compounds. Their structures were established by mass and NMR spectroscopy, especially NOE and HMBC experiments.

The method of indoor thermostatic culture was used to study the effects of different types of straw applied with N and P fertilizer on available N and P contents in a chao soil (alluvial soil). The results showed that the content of available N in...

The role of innate immune response mediated by Toll-like receptors in HCV infection, is not yet well understood and there is a lack of data regarding liver tissue expression of these molecules in chronic hepatitis C (CHC). Our study is aimed to in...

Ethyl carbamate (EC, urethan) is carcinogenic probably because it is converted in vivo to vinyl carbamate and then to vinyl carbamate epoxide, which reacts with DNA bases. We hypothesized that vinyl carbamate arises from EC by oxidation to 2-hydro...

Engagement of the IL-7R activates the intracellular enzyme phosphatidylin...
