Isoxazole

Customer Review

Based on 1 Customer Validation

Isoxazole is a member of the five-membered heterocycle drug scaffold. Isoxazole has been used as a BET bromodomain inhibitor and can improve β-cell function in a diabetic mouse model. Isoxazole and its derivatives exhibit broad biological activities (such as antimicrobial, antibacterial, antifungal, antiviral, anticancer, anti-inflammatory, immunomodulatory, analgesic, anti-tuberculosis, and anti-diabetic effects). For example, the bicyclic Isoxazole can act as an HSP90 inhibitor, and the tricyclic Isoxazole is promising as a selective multidrug resistance protein (MRP1) inhibitor.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
