IAA-94 belongs to the class of indanyloxyacetic acid derivatives and is known for its unique property as a blocker of epithelial chloride channels. IAA-94 has been widely employed in scientific research to modulate the function of chloride channels and investigate their dynamics and physiological roles. Chloride channels are membrane proteins that play a role in regulating chloride ion flux across cell membranes. By selectively blocking these channels, IAA-94 allows researchers to study the function and properties of chloride channels in various biological systems. One of the significant scientific applications of IAA-94 is its use as a tool to probe the dynamics and function of chloride channels. By selectively inhibiting chloride channels, researchers can investigate the impact of altered chloride flux on cellular processes and gain insights into the physiological roles of these channels in different tissues and organs. Furthermore, the high affinity of IAA-94 for chloride channels has been exploited for the isolation and reconstitution of these proteins. The compound′s strong binding to chloride channels allows researchers to effectively isolate and study these channels in their native form or reconstitute them in artificial lipid bilayers. This enables a more detailed examination of their structure, function, and pharmacological properties. The mechanism of action of IAA-94 involves its binding to specific sites on epithelial chloride channels, leading to the inhibition of chloride ion transport across cell membranes. This selective blocking of chloride channels by IAA-94 interferes with their normal function, providing researchers with a means to investigate the physiological and pathological roles of chloride channels in various biological systems.

Is it any evidence of IAA-94 crossing the plasma membrane?  Or does it acts on the Cl channels on the cellular membrane only? 

Asked by: RDFIE
Thank you for your inquiry. It has been shown that IAA-94 inhibits some CI channels located in the nucleoplasm, nuclear membrane, cytoplasm and plasma membrane. For instance IAA-94 blocks activity of CLIC1. However, I could not determine if IAA-94 crosses the cell membrane 'naturally', or if these findings were determined by placing IAA-94 intracellular. Here is a paper that may be helpful. http://ac.els-cdn.com/S0022202X15525712/1-s2.0-S0022202X15525712-main.pdf?_tid=037acaa6-f961-11e6-b2f3-00000aacb360&acdnat=1487810754_e40e08d1d3dcb9a54aa2adc8025018fb If you have any further questions, please contact our European Technical Service team.

Rated 5 out of 5 by from ChengCheng, G. et al. (PubMed 17126821) used IAA-94, a potent mammalian skeletal muscle and epithelial chloride channel blocker, to examine the effects on IGF-I induced proliferation in porcine vascular smooth muscle cells(VSMC) in cardiovascular diseases. They found that ClC-2, a member of the volume-regulated chloride channel family, plays a role in IGF-1 induced regulation of VSMC proliferation. -SCBT Publication Review
