title = "Unguiculins A-C: Cytotoxic bis-guanidine alkaloids from the French Polynesian sponge, Monanchora n. sp",
abstract = "Two new acyclic bis-guanidine alkaloids, unguiculins B-C (2–3), were isolated from a French Polynesian sponge Monanchora n. sp. together with the known compound unguiculin A (1). Their structures were established by spectroscopic data interpretation and comparison with the literature. Unguiculins A-C displayed antiproliferative and cytotoxic efficacy against several human cancer cells with IC50 values in the micromolar range.",
