Streptonigrin (Bruneomycin) is an orally active antibiotic and pan-PAD inhibitor, inhibiting PAD1, PAD2, PAD3 and PAD4 with IC₅₀ of 48.3 μM, 26.1 μM, 0.43 μM and 2.5 μM, respectively. Streptonigrin inhibits SENP1 (IC₅₀ of 0.518 μM) and reduces HIF1α. Streptonigrin increases p53 and Apoptosis. Streptonigrin shows antiviral activity against Rauscher murine leukemia virus. Streptonigrin has immunosuppressive effects. Streptonigrin has antitumor activity against osteosarcoma.

Streptonigrin (0.1-0.2 mg/kg; i.p.; on day 0, 2, 4, and 6; until day 7) significantly suppresses the proliferative response of T-cells rather than that of B-cells in C57BL/6 mice^[8].
Streptonigrin (0.1 mg/kg; p.o.; once a day; 5 days a week) increases the expression of p53 in tumors, and decreases the expression of Ki67 in the xenograft model of human renal cell carcinoma in BALB/c nude mice^[9].

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.
