The methanolic extract of Piper lolot, having shown potent inhibitory activity on platelet aggregation induced by arachidonic acid (AA) and platelet activating factor (PAF), was subjected to activity-guided isolation to yield twelve new amide alkaloids, piperlotine A-L (1-12), along with twenty-nine known compounds Their structures were elucidated on the basis of spectroscopic anal. The isolated compounds were tested for their inhibitory activity on the rabbit platelet aggregation. The compounds piperlotine A (I), piperlotine C, piperlotine D, piperlotine E, 3-phenyl-1-(2,4,6-trihydroxyphenyl)propan-1-one (21), 3-(4-methoxyphenyl)-1-(2,4,6-trihydroxyphenyl)propan-1-one (22), 1-trans-cinnamoylpyrrolidine (24), sarmentine (26), pellitorine (27), Me 3-phenylpropionate (32), and (10S)-10-hydroxypheophorbide a Me ester (40) showed potent antiplatelet aggregation activity. This study involved multiple reactions and reactants, such as (2E,4E)-N-Isobutyldeca-2,4-dienamide (cas: 18836-52-7Synthetic Route of C14H25NO).
(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. Amides are not in general accessible by the direct condensation of amines with carboxylic acids for two reasons: first, both components are readily deactivated by a transfer of a proton from the acid to the amine and second, the hydroxy unit on the carbonyl of the acid is a relatively poor leaving group. Nevertheless, the formation of five- and six-membered rings is often surprisingly simple provided that other factors can be brought into play to assist in the condensation.Synthetic Route of C14H25NO
