General description

2,2′-Dithiobis(5-nitropyridine) is an aromatic disulphide.

Application

2,2′-Dithiobis(5-nitropyridine) was employed:
  • as cysteine-activating reagent to study the NMR of G protein-coupled receptors
  • in the deprotection assays for protected selenocysteine-containing peptides
  • for deprotecting p-methoxybenzyl groups and acetamidomethyl groups from the side-chains of cysteine and selenocysteine
  • to remove the p-methoxybenzyl protecting group from cysteine and selenocysteine side-chains

Ca(2+)-activated K+ currents (IK(Ca)) and voltage-dependent Ca(2+)-insensitive K+ currents (IK(V)) were recorded using the patch clamp technique to study the pulmonary (PASMC) and ear arterial smooth muscle cells (EASMC) of the rabbit and the possible regulatory mechanisms related to hypoxia.

We present here a simple method for deprotecting p-methoxybenzyl groups and acetamidomethyl groups from the side-chains of cysteine and selenocysteine. This method uses the highly elecrophilic, aromatic disulfides 2,2'-dithiobis(5-nitropyridine) (DTNP) and 2,2'-dithiodipyridine (DTP) dissolved in TFA to effect removal of

Redox modulation of fast inactivation has been described in certain cloned A-type voltage-gated K(+) (Kv) channels in expressing systems, but the effects remain to be demonstrated in native neurons. In this study, we examined the effects of cysteine-specific redox agents

Binding of biomolecules to crystal surfaces is critical for effective biological applications of crystalline nanomaterials. Here, we present the modulation of exposed crystal facets as a feasible approach to enhance specific nanocrystal-biomolecule associations for improving cellular targeting and nanomaterial uptake.
