Connexin mimetic peptide 40GAP27 是一种生物活性肽，对应于主要的血管连接蛋白Cx40第二个细胞外环的GAP27结构域（40Gap27）。该化合物在研究氧化应激所致的损伤以及间隙连接通讯机制中有应用。40Gap27能够在给药后减少内皮依赖性的内膜下平滑肌的超极化现象。

Meclofenamate sodium is a potent non-steroidal anti-inflammatory agent, which can specifically inhibit chemokine-induced human polymorphonuclear leukocyte function: chemotaxis, degranulation, and superoxide anion free radical production.

Rotigaptide is a novel and specific modulator of Cx43 and is a potent AAP. Rotigaptide prevents the uncoupling of Cx43-mediated gap junction communication and normalizes cell-to-cell communication during acute metabolic stress.

Cx43 hemichannel blocker (IC50 ~7 μM). No significant affinity for gap junctions or Panx1 channels. N-terminal transactivator of transcription (TAT) motif promotes membrane permeability and increases inhibitory effect of Gap19. Active in vivo. Brain penet

AT-1001 (Larazotide) 是一种具有口服活性的紧密连接调节剂及连蛋白 (Zonulin) 拮抗剂。它通过阻断 Zonulin 受体信号通路维持肠道上皮细胞间紧密连接的完整性，能有效降低乳糜泻及炎症性肠病模型中的肠道通透性。
