ACS Med Chem Lett. 2016 Jan 22;7(3):335-9. doi: 10.1021/acsmedchemlett.5b00482. eCollection 2016 Mar 10.


The indole derivative, 3-((E)-3-((3-((E)-2-(7-chloroquinolin-2yl)vinyl)phenyl)amino)-3-oxoprop-1-en-1-yl)-7-methoxy-1H-indole-2-carboxylic acid (17k), was identified as a novel and highly potent and selective CysLT1 antagonist with IC50 values of 0.0059 ± 0.0011 and 15 ± 4 μM for CysLT1 and CysLT2, respectively.

Keywords: CysLT1; CysLT2; Cysteinyl leukotrienes; asthma; selective antagonists.
