摘要:
Pharmaceutical compositions having a cholesterol-lowering effect which comprises as the active ingredient a compound having a PPAR (peroxisome proliferator-activated receptor)&dgr; activating effect or a PPAR&dgr;- and PPAR&ggr;-activating effect or a pharmaceutically acceptable salt thereof; pharmaceutical compositions wherein the cholesterol-lowering effect is an LDL-cholesterol-lowering effect; and a method for identifying a compound having a cholesterol-lowering effect characterized by measuring the PPAR&dgr;-activating effect or the PPAR&dgr;- and PPAR&ggr;-activating effect thereof. Means for Solution: It is found out that a compound exerting an excellent cholesterol-lowering effect on higher animals such as humans and ape has an effect of activating PPAR&dgr; or PPAR&dgr; and PPAR&ggr;. Also, a method for identifying a compound having an excellent cholesterol-lowering effect was found, wherein the desired compound can be quickly and efficiently screened from among a number of compounds by measuring the PPAR&dgr;-activating effect or the PPAR&dgr;- and PPAR&ggr;-activating effect.
摘要:
The present invention relates to novel compounds having a phosphatidylinositol 3 kinase (PI3K) inhibiting activity which are useful as medicaments, more particularly as antitumor agent. Novel 3-(imidazo[1,2-a]pyridin-3-yl) derivatives or salts thereof exhibit an excellent PI3K inhibiting activity and cancer cell growth inhibiting activity, and are thus useful as medicaments, especially as PI3K inhibitors and antitumor agents.
