Three new amide alkaloids piperlongumamides A-C (1-3), together with 12 known ones (4-15), were isolated from the fruits of Piper longum. The structures of the new isolates were determined using spectroscopic data analyses. Cytotoxic activity of these amides against HL-60 (human leukemia), A-549 (human lung cancer), MCF-7 (human breast cancer), SMMC-7721 (human liver cancer) and SW480 (human rectal cancer) cell lines were evaluated. Piperchabamide B (11) exhibited weak inhibitory activity against HL-60 (IC50 = 21.32 μM ), A-549 (IC50 = 23.82 μM ) and MCF-7 (IC50 = 16.58 μM ) cell lines. [Figure not available: see fulltext.]. This study involved multiple reactions and reactants, such as (2E,4E)-N-Isobutyldeca-2,4-dienamide (cas: 18836-52-7Recommanded Product: 18836-52-7).
(2E,4E)-N-Isobutyldeca-2,4-dienamide (cas: 18836-52-7) belongs to amides. The amide group is called a peptide bond when it is part of the main chain of a protein, and an isopeptide bond when it occurs in a side chain, such as in the amino acids asparagine and glutamine. In simple aromatic amides, fragmentation occurs on both sides of the carbonyl group. If a hydrogen is available in N-substituted aromatic amides, it tends to migrate and form an aromatic amine and the loss of a ketene.Recommanded Product: 18836-52-7
