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 muM for CysLT1 and CysLT2, respectively.
cross-dehydrogenative coupling (CDC) reaction is an efficient strategy for indole synthesis. However, most CDC methods require special substrates, and the presence of inherent groups limits the versatility for further transformation. A carboxylic acid-promoted aerobic catalytic system is developed herein for a single-step synthesis of indoles from simple anilines and ketones. This versatile system is featured
Novel indole derivatives of formula (I) or a pharmaceutically acceptable salt thereof:
wherein R
1
is fluorine, or chlorine, and R
2
is hydrogen, or fluorine, which are SGLT inhibitors and are useful for treatment or prevention of diabetes and related conditions.
