AT-533

AT-533
AT-533 is a potent inhibitor of Hsp90 and HSV. AT-533 blocks the HIF-1α/VEGF/VEGFR-2 signaling pathway, leading to suppress tumor growth and angiogenesis. AT-533 also inhibits the activation of the downstream pathways, including Erk1/2, FAK, Akt/mTOR/p70S6K,. AT-533 inhibits the cell migration, invasion, and the tube formation of human umbilical vein endothelial cells (HUVECs).

Product Introduction

Bioactivity
Description
AT-533 is a potent inhibitor of Hsp90 and HSV. AT-533 blocks the HIF-1α/VEGF/VEGFR-2 signaling pathway, leading to suppress tumor growth and angiogenesis. AT-533 also inhibits the activation of the downstream pathways, including Erk1/2, FAK, Akt/mTOR/p70S6K,. AT-533 inhibits the cell migration, invasion, and the tube formation of human umbilical vein endothelial cells (HUVECs).
In vitro
AT-533 (0-1350 nM; 24h or 48h) inhibits 20 ng/mL VEGF-induced tube formation, cell migration, and HUVEC invasion. Additionally, AT-533 (2 μM or 75 μM; 24h) hinders the HIF-1α/VEGF signaling pathway in hypoxia-induced breast cancer cells and inhibits Akt/mTOR/p70S6K, Erk1/2, and FAK phosphorylation. It shows anti-angiogenic activity on the chorionic villus (CAM) model at 10 nM and 50 nM over 48h. Furthermore, AT-533 (0.5 μM; 2 or 4 hours) reduces TNF-α, IL-1β, and IL-6 production induced by HSV-1 in RAW264.7 and BV2 cells [1, 2].
In vivo
AT-533 (10 mg/kg; intraperitoneal injection; once daily for 21 days) inhibited the expression of HIF-1α/VEGF signaling pathway-related proteins in a mouse MDA-MB-231 xenograft model of breast cancer [1]. AT-533 (1, 2, 4 mg/kg; intraperitoneal injection; once daily for 30 days) did not cause death, appetite loss, weight loss, or adverse reactions in subacute toxicity tests of Sprague Dawley rats [3].

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
