Biochem/physiol Actions

Indazole-Cl is a selective estrogen receptor modifier (SERM), a selective ERβ agonist with > 100-fold selectivity for ERβ over Erα. In a recent study reported in Cell, Indazole-Cl, but not structurally distinct ERβ-specific ligands DPN and ERB-041, blocked the expression of proinflammatory genes in microglia and astrocytes, repressing induction of factors that promote Th17 T cell differentiation and activation. Indazole-Cl is believed to bind to the ERβ that is part of an ADIOL-ERβ-CtBP transrepression pathway that mediates recruitment of CtBP corepressor complexes to AP-1-dependent promoters, repressing genes that amplify inflammatory responses and activate Th17 T cells. In studies of experimental autoimmune encephalitis (EAE), a mouse model of Multiple sclerosis, Indazole-Cl both prevented the development of EAE when given prophylactically and caused significant improvement of EAE when provided to mice after they exhibited symptoms of disease.

Acting during phase II metabolism, sulfotransferases (SULTs) serve detoxification by transforming a broad spectrum of compounds from pharmaceutical, nutritional, or environmental sources into more easily excretable metabolites. However, SULT activity has also been shown to promote formation of reactive metabolites
