Product Information
| Description: | Sulfisoxazole is a sulfonamide antibacterial with an oxazole substituent. Sulfisoxazole (Sulfafurazole) is an orally active endothelin receptor antagonist with IC50 values of 0.60 μM and 22 μM against endothelin receptor A and endothelin receptor B, respectively. Sulfisoxazole inhibits breast cancer exosome release by targeting endothelin receptor A. |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
