Abstract
Bioactivity-guided fractionation of a methanolic CHCl3 extract of the leaves of Pterogyne nitens afforded the known guanidine alkaloid ptero gynidine (2) and three new guanidine alkaloids, nitensidines A (3), B (4), and C (5), all of which exhibited selective activity towards the DNA repair-deficient yeast mutant RS 321 (IC12 = 9.3 - 20.0 mu g/ml); 3,4, and 5 were moderately cytotoxic to CHO Aux B-1 cells (IC50 = 8.5 - 13.0 mu g/ml).
