The essential oil of the leaves of P. racemosa var. terebinthina and P. racemosa var. grisea were examined by GC and GC/MS. The major constituents were alpha-terpineol acetate (27%), alpha-terpineol (20%) and 4-methoxy eugenol (12.6%) for Pracemosa var. terebinthina and 4-methoxy-isoeugenol (75.2%) and 4-methoxy-eugenol (4.5%) for P. racemosa var. grisea.

Three quinone-type podocarpanes, 3beta-hydroxy-13-methoxy-8,12-podocarpadiene-11,14-dione (1), 18-hydroxy-13-methoxy-8,12-podocarpadiene-11,14-dione (2), and 13-methoxy-8,12-podocarpadiene-2,11,14-trione (3) were isolated from the bark of Taiwania cryptomerioides. Their structures were elucidated using spectral methods.

We investigated the effects of 1-methoxy-canthin-6-one, isolated from the medicinal plant Ailanthus altissima Swingle, on apoptosis in human leukemia (Jurkat), thyroid carcinoma (ARO and NPA), and hepatocellular carcinoma (HuH7) cell lines. Cultures incubated with the compound showed >50% of sub-G1 (hypodiploid) elements in flow cytometry analysis; the apoptosis-inducing activity was evident at...

Herein, we report a copper-catalyzed C-O cross-coupling of N-methoxy amides and arylboronic acids for the synthesis aryl-N-methoxy arylimides. The fully selective O-arylation is found to be greatly prompted by inexpensive commercially available CuI. reaction conditions tolerate variety functional groups promote different reactivities depending on electronic steric properties distorted substrates.
