They are nvolved as an example epthelal flud secreton, cell volume regulaton, neuroexctaton, smooth muscle contractoand acdfcatoof ntracellular organelles.Dseases assocated wth chlorde channels are cystc fbross, macular degeneraton, myotona, kdney stones, renal salt wastng, secretory darrhoeas, polycystc kdney dsease, osteopoross selleck inhibitor andhypertensoandhyperekplexa, simply to name a number of.By way of example, mutatons the cystc fbross transmembrane conductance regulator chlorde channel result in cystc fbross.cylamnocarboxamdes 212has beedentfed byhgh throughput screenng and cabe accessed synthetcally by a classcal Ug 4 CR.169 Ths phenylglycne dervatve cacorrect defectve gatng various CF causng CFTR mutants.So compound 212 could dsplay a lead framework for that advancement of the drug for cystc fbross.Calcum actvated chlorde channels are wdely expressed mammalatssues, ncludng ntestnal epthela, the place they factate flud secreton.Potent, selectve CaCC nhbtorshave not beeavaable.
