Pyrrolizidine alkaloid-derived DNA adducts as a common biological biomarker of pyrrolizidine alkaloid-induced tumorigenicity.

Chemical Research in Toxicology, 2013
Pyrrolizidine alkaloid-containing plants are the most common poisonous plants affecting livestock, wildlife, and humans. The U.S. National Toxicology Program (NTP) classified riddelliine, a tumorigenic pyrrolizidine alkaloid, as "reasonably anticipated ...

Biotransformation of alkaloids

2001
Biotransformations of alkaloids over the last decade have continued to encompass a wide variety of substrates and enzymes. The elucidation of novel alkaloid biosynthetic and catabolic pathways will continue to furnish new biocatalysts for the synthetic organic chemist.

Evaluation of Green Corrosion Inhibition by Alkaloid Extracts of Ochrosia oppositifolia and Isoreserpiline against Mild Steel in 1 M HCl Medium

, 2013
Alkaloid extracts of leaves (OOL) and bark (OOB) of Ochrosia oppositifolia, as well as isoreserpiline (ISR), the major alkaloid isolated from OOL and OOB, were investigated as potential corrosion inhibitors for mild steel (MS) in 1 M HCl medium.

Plant Alkaloids: The Vinca Alkaloids [PDF]

, 1989
Although a large number of compounds from a wide variety of plants have been tested for antitumor activity, none has played a more vital role in cancer chemotherapy than the vinca alkaloids. These compounds are present in minute quantities in the plant Catharanthus roseus G. Don (Vinca rosea Linn.), commonly called the periwinkle.
