| Targets |
Indazole-Cl targets the estrogen receptor beta (ERβ). It is a selective ERβ agonist with >100-fold selectivity for ERβ over ERα. By activating ERβ, it modulates estrogen receptor signaling. It also has inflammatory effects and inhibits COX-2 expression reduction induced by hypoxia. It prevents hypoxia-induced VSMC migration and invasion.

|---|---|
| ln Vitro |
Vascular smooth muscle cells (VSMC) with hypoxia-induced intracellular ROS levels are lessened by indazole-Cl (0.1 μM; 6 hours) [1]. Induction of oxidative synthase in VSMCs by hypoxia is inhibited by indazole-Cl (10 μM; 24 hours). VSMCs' internalization and hypoxia-induced cell migration are inhibited by indazole-Cl (1 μM; 24-72 hours) [1].
Indazole-Cl is a selective ERβ agonist and a selective estrogen receptor modifier (SERM). It has inflammatory effects. It inhibits the hypoxia-induced decrease in COX-2 expression and inhibits ROS production. It prevents hypoxia-induced VSMC migration and invasion. Its activity has been confirmed in various in vitro and in vivo studies. |
| ln Vivo |
Indazole-Cl prevents hypoxia-induced VSMC migration and invasion. It inhibits the hypoxia-induced decrease in COX-2 expression and inhibits ROS production. Its effects on estrogen receptor signaling and inflammation make it a valuable research tool for studying the role of ERβ in various physiological and pathological processes.
|
| Enzyme Assay |
The primary in vitro assays for Indazole-Cl include radioligand binding assays to measure its affinity for ERβ and ERα. The compound's ability to displace labeled estradiol from ERβ and ERα is measured to determine its selectivity. Functional assays measure its ability to activate ERβ-mediated transcription in reporter gene assays. Its effects on COX-2 expression and ROS production are assessed in cell-based assays.
|
| Cell Assay |
In vitro cellular experiments for Indazole-Cl involve treating cells, such as vascular smooth muscle cells, with the compound and measuring its effects on ERβ activation, COX-2 expression, ROS production, and cell migration. The activation of ERβ is assessed by measuring the expression of ERβ target genes. COX-2 expression is measured by Western blot or qPCR. ROS production is measured using fluorescent probes. Cell migration is assessed using wound healing or transwell migration assays.

| Animal Protocol |
In vivo animal experiments for Indazole-Cl are not extensively detailed in the available literature. As an ERβ agonist, it could be evaluated in animal models of cardiovascular disease, inflammation, or cancer where ERβ plays a role. Its effects on disease progression and inflammatory markers would be assessed.

Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).
