NBI-31772 is a non-selective IGFBP inhibitor (Ki=47 nM). NBI-31772 has neuroprotective effects and reduces infarct volume during cerebral ischemia. NBI-31772 can also restore or enhance proteoglycan synthesis in osteoarticular chondrocytes. In addition, NBI-31772 also increases the effect of IGF3 on zebrafish oocyte maturation.

Description

NBI-31772 is a non-selective IGFBP inhibitor (Ki=47 nM). NBI-31772 has neuroprotective effects and reduces infarct volume during cerebral ischemia. NBI-31772 can also restore or enhance proteoglycan synthesis in osteoarticular chondrocytes. In addition, NBI-31772 also increases the effect of IGF3 on zebrafish oocyte maturation[1][2][3][4].

In Vitro

NBI-31772 (0.1-10 µM; 24 h) stimulates the synthesis of IGF-1-dependent proteoglycans in human OA chondrocytes in a dose-dependent manner[3].
NBI-31772 (0.1-10 µM; 24 h) significantly stimulates the percentage of rabbit articular chondrocyte-associated proteoglycans in the presence of IGF-1 and IGFBP-3[3].
NBI-31772 (5-100 µM; 16 h) dose-dependently induces the maturation of zebrafish oocytes[4].

In Vivo

NBI-31772 (5-100 μg; siv; administered at the onset of ischemia) dose-dependently reduces total infarct volume and cortical infarct volume at the onset of ischemia in rats with middle cerebral artery occlusion (MCAO) model[2].
NBI-31772 (50 μg; i.v.; administered 0, 1, 2, or 3 hours after MCAO) reduces cortical infarct size and brain swelling in rats with intraluminal suture MCAO model[2].
NBI-31772 (0.4 μM/strip; i.p.; 4 h) induces germinal vesicle rupture in zebrafish[4].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: MCAO model rats[2]
Dosage: 5, 50 and 100 μg
Administration: siv; Drug administration during ischemic episodes
Result: Had similar effects on total lesion volume at the 50 and 100 μg doses.
Affected striatal lesion volume at the 50 μg dose.
Animal Model: Intraluminal suture MCAO model rats[2]
Dosage: 50 μg
Administration: i.v.; Administration 0, 1, 2, or 3 hours after MCAO
Result: The greatest lesion reduction was observed when the drug was administered immediately after MCAO.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
