Phthalide is an amoebic actinic admixture with the atomic blueprint C8H6O2. It is a lactone that serves as the amount actinic anatomy for a array of added circuitous actinic compounds including dyes (such as phenolphthalein), fungicides (such as tetrachlorophthalide, generally referred to artlessly as "phthalide") and accustomed oils (such as butylphthalide).
Chromanol is a acquaintance of the apathetic delayed rectifier K+ accepted via KCNQ1 channels. Aswell blocks CFTR chloride current.
The chromanol 293B (293B, trans-6-cyano-4-(N-ethylsulfonyl-N-methylamino)-3-hydroxy-2,2-dimethyl-chroman) is a advance admixture of abeyant chic III antiarrhythmics that arrest cardiac IKs potassium channels. These channels are formed by the coassembly of KCNQ1 (Kv7.1, KvLQT1) and KCNE1 subunits. Although homomeric KCNQ1 channels are the arch atomic targets, access of KCNE1 to the approach circuitous enhances the chromanol block. Because carefully accompanying neuronal KCNQ2 potassium channels are aloof to the drug, we acclimated KCNQ1/KCNQ2 chimeras to analyze the bounden website of the inhibitor. We localized the accepted biologic receptor to the H5 selectivity clarify and the S6 transmembrane segment. Single residues affecting 293B inhibition were after articular through analytical barter of amino acids that were either altered in KCNQ1 and KCNQ2 or predicted by a advancing archetypal of 293B in the accessible and bankrupt anatomy of KCNQ1. Mutant approach proteins T312S, I337V, and F340Y displayed badly bargain acuteness to chromanol block. The predicted biologic bounden receptor lies in the close pore antechamber absolute the lower allotment of the selectivity filter, and the S6 transmembrane area aswell appear to be important for bounden of benzodiazepines.
