Abstract:
LC-MS/MS-based screening of the dichloromethane extract of the gorgonian coral Pseudopterogorgia acerosa led to the isolation of a novel bis(pseudopterane) amine (1). The structural assignment of 1 was achieved by 1D and 2D NMR and mass spectrometry analysis. A biomimetic synthesis of 1 and the known symmetrical diterpene 2 from pseudopterolide (3) is described in this report. Bis(pseudopterane) amine showed selective growth inhibition activity against cancer cell lines with IC(50) values of 4.2 microM (HCT116) and 42 microM (HeLa).

Physical Properties of Amines
Preparation of 1° Amines: Azide Synthesis
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...
Preparation of 1° Amines: Gabriel Synthesis
Strong bases like NaOH or KOH deprotonate the phthalimide to form the corresponding anion, which acts as a nucleophile. Further, the anion attacks an...
