2-Iminobiotin (Guanidinobiotin) is a biotin (vitamin H or B7) analog. 2-Iminobiotin is a reversible nitric oxide synthases inhibitor with Kis of 21.8 and 37.5μM for murine iNOS and rat n-cNOS, respectively. 2-Iminobiotin superimposes on hypothermia protects human neuronal cells from hypoxia-induced cell damage.

At equivalent molar concentrations, both the salt and free forms of a compound exhibit comparable biological activity. Nevertheless, the salt form (2-Iminobiotin hydrobromide) usually boasts enhanced water solubility and stability.

Description

2-Iminobiotin (Guanidinobiotin) is a biotin (vitamin H or B7) analog. 2-Iminobiotin is a reversible nitric oxide synthases inhibitor with Kis of 21.8 and 37.5μM for murine iNOS and rat n-cNOS, respectively[1]. 2-Iminobiotin superimposes on hypothermia protects human neuronal cells from hypoxia-induced cell damage[2].

IC50 & Target

iNOS

 

In Vitro

Application of low concentrations of 2-Iminobiotin (2-IB; 10 ng/mL and 30 ng/mL) superimposed on hypothermia abrogates the hypoxia-induced lactate dehydrogenase (LDH) increase, resulting in LDH levels that were not different from the normoxia control[1].

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.
