Chromanol 293B is a selective blocker of the slow delayed rectifier K + current (IKs) with IC 50 of 1-10 μM and a weak inhibitor of KATP channel. Chromanol 293B also blocks the CFTR chloride current with an IC 50 of 19 μM.

The tests prescribed by NRS 293B.150 and 293B.165 must be conducted by processing a preaudited group of logic and accuracy test ballots so voted or marked as to record a predetermined number of valid votes for each candidate and on each measure, and must include for each office one or more ballots which have votes in excess of the number ...

Chromanol 293B作为调节离子通道活性的有效剂，通过与KCNQ1通道的相互作用，特异性地靶向慢延迟整流K+电流。 这一作用对于理解控制心脏和神经元兴奋性的复杂机制至关重要，为研究这些组织的电特性提供了关键工具。

PHL 293B, also known as Kinman's dwarf, is a low-metallicity blue compact dwarf galaxy about 22.6 Mpc from the Earth in the constellation Aquarius. [2] It had a very likely associated, notable, blue-light, long-lived star with constant outbursts or a large supernova observed to have faded and which then disappeared.

The chromanol derivate 293B blocks currents expressed by minK and not HERG in Xenopus oocytes, but little is known about its effects on native currents and action potentials. We aimed to establish the effects of 293B on K+, Na+ and Ca2+ currents and action potentials in human and guinea pig cardiomyocytes.

(a) Processing on a mechanical recording device, during the periods prescribed in NRS 293B.150 and 293B.165, a group of logic and accuracy test ballots voted so as to record: (1) A vote for each candidate and a vote for and against each measure on the ballot;
