Piperic acid derivatives were found to affect the islet amyloid polypeptide (IAPP) aggregation process. Structure-activity relationship studies revealed that PAD-13 was an efficient molecular modulator to accelerate IAPP fibril formation by promoting primary and secondary nucleation and reducing its antimicrobial activity.

Background: Medicinal plants are invaluable sources of novel medications worldwide, used for centuries due to their therapeutic properties and health benefits. Comprehensive quality evaluation and monitoring studies are available on single medicinal plant, however, there are limited data on plant-based formulations especially the formulations described in ancient texts.
Objective: Qualitative and quantitative evaluation of the phytochemicals present and the identification of active phytocompounds of a traditional Unani plant-based formulation (Zingiber officinalis, Piper longum, Coptis teeta, Piper nigrum, and Foeniculum vulgare) described by distinguished Persian physician of 10th century, Abul-Mansoor ul Hasan Qamari (d.

Piperine, the alkaloid from Black pepper, is known for its wide range of pharmacological effects. The DNA binding activity of piperine was reported earlier. In this work, we explore the DNA duplex binding properties of four piperine derivatives, piperonal, piperonyl alcohol, piperonylic acid, and piperic acid using biophysical and computational techniques.

A protocol for a tandem copper-catalyzed intermolecular decarboxylation cross-coupling cascade between -bromobenzoic acids and proline or piperic acid has been disclosed. The developed protocol allows access to a variety of synthetically useful fused benzoxazinones scaffolds with high efficiency and good functional group compatibility. A mechanistically sequential approach for the decarboxylation and dehydration coupling process was presented.
