Abstract:
Available online A series of thirteen novel zerumbone oxime esters and five new azazerumbone derivatives were successfully synthesized. Most of these derivatives exhibited significant cytotoxic activity against four human tumor cell lines (HepG2, A549, HL-60, and AGS). Among them, three derivatives (3i, 3j, and 3k) demonstrated strong cytotoxic effects against all tested cell lines, with IC50 values ranging from 0.41 ± 0.05 to 3.88 ± 0.19 μg/mL, displaying potency comparable to that of zerumbone and ellipticine. Docking results revealed that one compound (3i) showed the highest binding affinity for NF-κB p65.

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...
