Normonanchocidins A, B and D, New Pentacyclic Guanidine Alkaloids from the Far-Eastern Marine Sponge Monanchora pulchra
New pentacyclic guanidine alkaloids, normonanchocidins A, B and D (1–3) along with the earlier known monanchocidin A were isolated from the Far-Eastern marine sponge Monanchora pulchra. Structures ofExpand
Urupocidin A: a new, inducing iNOS expression bicyclic guanidine alkaloid from the marine sponge Monanchora pulchra.
Urupocidins A and B (1 and 2), bisguanidine alkaloids with an unprecedented skeleton system, derived from polyketide precursors and containing an unusual N-alkyl-N-hydroxyguanidine moiety, have beenExpand
Monanchomycalin C, a New Pentacyclic Guanidine Alkaloid from the Far-Eastern Marine Sponge Monanchora Pulchra
A new pentacyclic guanidine alkaloid, monanchomycalin C (1), along with the earlier known ptilomycalin A (2), were isolated from the Far-Eastern marine sponge Monanchora pulchra. The structure of 1Expand
Anti‐migratory activity of marine alkaloid monanchocidin A – proteomics‐based discovery and confirmation
Monanchocidin A (MonA) is a novel marine alkaloid with promising anti‐cancer properties. We recently demonstrated its high efficacy in human urogenital cancers including germ cell tumors. Here, weExpand
Pulchranins B and C, New Acyclic Guanidine Alkaloids from the Far-Eastern Marine Sponge Monanchora Pulchra
New marine natural products, pulchranins B and C (2 and 3), were isolated from the marine sponge Monanchora pulchra and their structures were established using NMR and MS analysis. Compounds 2 and 3Expand
