Usage

Uses

Used in Biochemical Research:
2,2'-Dithiobis(5-nitropyridine) is used as a cysteine-activating reagent for studying the Nuclear Magnetic Resonance (NMR) of G protein-coupled receptors. This application aids in the deprotection assays for protected selenocysteine-containing peptides, which is crucial for understanding the structure and function of these receptors.
Used in Pharmaceutical Industry:
In the pharmaceutical industry, 2,2'-Dithiobis(5-nitropyridine) serves as a reagent for deprotecting p-methoxybenzyl groups and acetamidomethyl groups from the side-chains of cysteine and selenocysteine. This process is essential for the synthesis and development of various therapeutic agents, as it allows for the proper functionalization and modification of these molecules.
Additionally, 2,2'-Dithiobis(5-nitropyridine) is employed to remove the p-methoxybenzyl protecting group from cysteine and selenocysteine side-chains. This step is vital in the synthesis of peptides and proteins, ensuring that the desired functional groups are accessible for further modification or interaction with other molecules.

IF5 affects the final stage of the Cl-F exchange fluorination in the synthesis of pentafluoro-λ6-sulfanyl-pyridines, pyrimidines and benzenes with electron-withdrawing substituents

A difficult chlorine-fluorine (Cl-F) exchange fluorination reaction in the final stage of the preparation of pentafluoro-λ6-sulfanyl-(hetero)arenes having electron-withdrawing substituents has now been elucidated through the use of iodine pentafluoride. A major side-reaction of C-S bond cleavage was sufficiently inhibited by the potential interaction between F and I with a halogen bonding.

Silver-induced self-immolative Cl-F exchange fluorination of arylsulfur chlorotetrafluorides: Synthesis of arylsulfur pentafluorides

A novel strategy for the synthesis of arylsulfur pentafluorides by silver carbonate-induced Cl-F exchange fluorination of arylsulfur chlorotetrafluorides is reported. This fluorination does not require any exogenous fluoride sources. Rather, the reaction proceeds via the self-immolation of the substrate Ar-SF4Cl.

Base-protected nucleotide analogs with protected thiol groups

The present invention is directed to protected thiol analogs of pyrimidine bases for syntheses of DNA and RNA by chemical or enzymatic methods. The subject analogs include reagents suitable for DNA or RNA synthesis via phosphoramidite, H-phosphonate or phosphotriester chemistry as well a reagents suitable for use by RNA and DNA polymerase, including thermostable polymerases employed by PCR or other nucleic acid amplification techniques. The nucleotide analogs synthesized by methods of this invention can thus be incorporated into oligonucleotides or polynucleotides, deprotected and derivatized with a functional group. In some cases the protecting groups are themselves antigenic and may be left on the oligonucleotides or polynucleotides for detection with antibodies. A method of synthesizing oligonucleotides with a functional group using the subject nucleotide analogs is also provided.

Studies on Anticoccidial Agents. 13. Synthesis and Anticoccidial Activity of Nitropyridine-2- and -3-sulfonamides and Derivatives

Eight nitropyridinesulfonamides andd pyridinesulfonamide N-oxides as their bioisosteres were prepared and evaluated for anticoccidial activity.Of these compounds, 2-, 4- and 5-nitropyridine-3-sulfonamides and pyridine-2- and -3-sulfonamide N-oxides were found to be active against Eimeria tenella.Thus, the relative positions, ortho or meta, of the substituents in nitropyridine-3-sulfonamides and pyridinesulfonamide N-oxides are important for anticoccidial activity.N-Substituted analogues of 5-nitropyridine-3-sulfonamide were also prepared and optimal anticoccidial activity was attained with the sulfonamide and its lower N-alkyl derivatives.The mode of action of 5-nitropyridine-3-sulfonamide was examined and found to be active in the sporozoite and the first schizogony stages.
