New clerodane diterpenoids from Croton crassifolius
Fitoterapia, 2016Two new clerodane diterpenoids (1-2), one new clerodane diterpenoid alkaloid (3), as well as thirteen known compounds were isolated from Croton crassifolius. The structures of new compounds were established by a combination of spectroscopic methods, including HRMS, (1)H NMR, (13)C NMR, (1)H (1)H COSY, HSQC, HMBC, NOESY and X-ray crystallographic ...

Clerodane-type diterpenoids from Nannoglottis ravida
Phytochemistry, 2004Chemical investigation of the roots of Nannoglottis ravida resulted in the characterization of two 5alpha,10alpha-cis-clerodane-type diterpenoides, ravidin A and B. Their structures and stereochemistry were established by spectroscopic methods, including X-ray crystallographic diffraction analysis of ravidin A.

Cytotoxic clerodane diterpenoids from Croton crassifolius
Bioorganic & Medicinal Chemistry Letters, 2017Hepatocellular carcinoma (HCC) is the most common type of liver cancer, and treatment options for HCC are limited. In addition, the discovery of new natural compounds with anti-hepatocarcinoma activity is attracting increasing attention. For this reason, phytochemical investigation of Croton crassifolius led to the isolation of 17 diterpenoids ...
