• Rapakinin Vasorelaxation in Hypertensive Rat Arteries

  2026-08-13

  The reference study shows that rapakinin, an Arg-Ile-Tyr peptide derived from rapeseed protein, relaxes mesenteric arteries from spontaneously hypertensive rats through a prostaglandin I2–IP receptor pathway linked to downstream CCK1 receptor signaling. Its limited dependence on nitric oxide synthase and bradykinin receptors distinguishes this mechanism from classical ACE inhibitor responses and provides a useful framework for vascular tone regulation studies.

• Calpeptin: Calpain Inhibitor Evidence Guide

  2026-08-10

  Calpeptin is a nanomolar calpain inhibitor used to study calcium-dependent cysteine protease signaling. Product information and preclinical evidence support its use in pulmonary fibrosis research, while cancer extracellular-vesicle findings provide a separate, hypothesis-generating application.

• N4-Acetylcytidine: RNA Modification Research

  2026-08-09

  N4-Acetylcytidine is a chemically defined acetylated cytidine used to study RNA modification chemistry and nucleotide processing. The key mechanistic boundary is that EcYqfB hydrolyzes free ac4C nucleoside but does not remove ac4C from RNA, making substrate form critical in assay design.
