A total of eighteen piperic acid (PA) and 4-ethylpiperic acid (EPA) amides (C1–C18) with α-, β- and γ-amino acids were synthesized, characterized and evaluated for their efflux pump inhibitory activity against ciprofloxacin resistant Staphylococcus aureus. The amides were screened against NorA overexpressing S. aureus SA-1199B and wild type S. aureus SA-1199 using ethidium bromide as NorA efflux pump substrate. EPI C6 was found to be most potent and reduced the MIC of ciprofloxacin by 16 fold followed by C18 which showed 4 fold reduction of MIC. Ethidium bromide efflux inhibition and accumulation assay proved these compounds as NorA inhibitors.

A series of piperine-based dienehydrazide derivatives were designed and synthesized to be used as insecticides against Culex pipiens. The chemical structure of compound 5n was confirmed by single-crystal x-ray diffraction. Their insecticidal activities of

Piperine amide analogs are synthesized by replacement of the piperidine moiety with different types of cyclic amines, including adamantyl and monoterpene-derived fragments. The compounds are screened for activity against Mycobacterium tuberculosis H37Rv. The most potent compounds are the 1-adamantyl and the monoterpene-derived hybrids, which combine nanomolar antimycobacterial activity with low cytotoxicity against human cells. The presence of quaternary carbon atom as main structural requirement for anti-TB activity is pointed out by a QSAR study. The most promising compound is the (+)-isopinocampheylamine-derived amide which is characterized with selectivity index of 1387.8.

Seven piperic acid amides along with their lower homologs (12) were synthesized using HATU-DIPEA coupling reagent. All the synthesized derivatives were evaluated for their antibacterial activities against Staphylococcus aureus, Pseudomonas aeruginosa, and vancomycin-resistant P. aeruginosa. They were found to be more active on P. aeruginosa than on S. aureus. However, they did not exhibit potent activity on Vancomycin resistant P. aeruginosa. Among the tested compounds, methylenedioxycinnamic acid amide of anthranilic acid (MDCA-AA, 2a) was found to be most active against S. aureus with MIC of 3.125 μg/ml. The PAS and INH amides of piperic acid were screened against Mycobacterium tuberculosis H37Ra strain. They were found to be most active among all the tested compounds but were found to be less active than the standard drug, isoniazid.

The natural lipophilic amides piperine and piperiline were isolated from Piper nigrum L (Piperaceae). Piperine was hydrolysed into piperic acid (85% yield) which was converted into 16 amides (28-89% yield). The contact toxicity of all synthetic amides, and also that of piperine and piperiline, at the dose 10 μg per insect, was evaluated for the Brazilian economically important insects Ascia monuste orseis Latr, Acanthoscelides obtectus Say, Brevicoryne brassicae L, Protopolybia exigua DeSaus and Cornitermes cumulans Kollar. The results demonstrated that the insects have different sensivities to the various amides, with mortality ranging from 0 to 97.5% according to the compound and insect species.

Synthesis, in vitro and in silico anti-bacterial analysis of piperine and piperic ester analogues

, p. 19 - 29 (2021)
A set of 12 analogues of piperine was designed, replacing the amide functional group of the molecule with different aliphatic and aromatic ester functional groups. Molecular docking studies of these molecules with FDA-approved target proteins for anti-bacterial drugs were done. The binding energy of the proteins and the ligands were low and the analogues were found to be drug-like based on the ADME results; hence, the molecules were synthesized. The synthesized compounds were tested for their anti-bacterial property against six bacterial species via Agar well-diffusion method. Acinetobacter baumannii, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Enterococcus faecalis and Staphylococcus epidermidis were the strains tested. The overall susceptibility is higher in gram-positive. The analogues showed better activity than piperine. The analogues, propyl piperic ester (P3) and 2-fluorophenyl piperic ester (P9) and 4-fluorophenyl piperic ester (P10) showed comparatively bigger inhibition zones for all the strains.

Piperine is a component of pepper which has earlier been reported as anticancer active compound. This work is emphasized on the design and synthesis of new hybrid piperine analogs by coupling piperine with the amine group of oxadiazoles and thiadiazoles.
A Short, Efficient, and Stereoselective Synthesis of Piperine and its Analogues
Bauer, Adriano,Nam, Jun-Hyun,Maulide, Nuno
, p. 413 - 416 (2019)
A quantitative synthesis of piperine from commercially available starting material is presented. The synthesis relies on a stereoselective nucleophilic attack of an in situ generated cuprate onto a cyclobutene lactone. The so-formed aryl-substituted cyclobutene spontaneously undergoes a conrotatory 4π-electrocyclic ring opening to form the 4-aryl pentadienoic acid as a single diastereoisomer. The high-yielding synthesis can be easily modulated on the aryl and on the amide moiety for the synthesis of a wide range of piperine analogues.
