“…The indazole ring system is regarded as a bioisostere of indole. However, a large number of synthetically prepared indazoles are known to show a variety of biological activities, such as high binding affinity for estrogen receptor 1,2 , inhibition of protein kinase C-β 3 , 5-HT2 receptor agonism 4 , human immunodeficiency virus (HIV) protease inhibition 5 , anti-leukemic activity 6 , and non-steroidal anti-inflammatory activity 7 . Other compounds of interest are YC-1, a benzylindazole which has been shown to activate soluble guanylate cyclase 8 , nitric oxide synthase inhibition activity 9,10 , to induce cellular apoptosis 11 and a MCHr1 antagonism for the treatment of obesity 12 .…”
