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.
Concanamycin A (Folimycin) 是一种多聚环内酯类抗生素,是选择性空泡状 H+-ATP 酶 (V-ATPase) 和溶酶体酸化抑制剂,可用于研究炎症。Concanamycin A 可增强细胞毒性 T 淋巴细胞对受感染原代细胞的免疫清除,抑制来自 HIV 和猿猴免疫缺陷病毒不同分支的 Nef 等位基因,可用于研究HIV 感染。
TAT-Gap19(I130A) is a control peptide for TAT-Gap19, a Cx43 hemichannel blocker. TAT-Gap19(I130A) consists of TAT-GAP19 with a I130A amino acid residue change at a key residue for GAP19 activity. In C6 glioma cells expression Cx43, TAT-GAP19(1130A) does not inhibit [Ca2+]i-triggered ATP release at 200 μM. TAT-Gap19(I130A) is cell permeable.
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
