Dicubyl disulfide (1) has been prepared in six steps from commercially available dimethyl-1,4-cubanedicarboxylate in 47% overall yield. In the final step, the previously unknown cubanethiol 2 was oxidized to disulfide 1. X-ray crystallography for 1 reveals the shortest tetragonal C-S bond on record (1.771 A).

Biochemistry, 2006
Disulfide bonds have been generally considered to be either structural or catalytic. Structural bonds stabilize a protein, while catalytic bonds mediate thiol-disulfide interchange reactions in substrate proteins. There is emerging evidence for a third type of disulfide bond that can control protein function by triggering a conformational change when ...

During the maturation of extracellular proteins, disulfide bonds that chemically cross-link specific cysteines are often added to stabilize a protein or to join it covalently to other proteins. Disulfide formation, which requires a change in the covalent structure of the protein, occurs as the protein folds into its three-dimensional structure.

A 45-year-old nondiabetic man presented with features resembling diabetic triopathy. He worked in a rayon manufacturing plant and was exposed to toxic levels of carbon disulfide (CS(2)). Clinical abnormalities included peripheral and central nervous system abnormalities as well as retinopathy, dyslipidemia, cardiovascular disease, and nephrotic ...

Disulfide luminescence. Emission characteristics of cyclic tetrapeptide disulfides
Biochemical and Biophysical Research Communications, 1981Luminescence has been detected in cyclic tetrapeptide disulfides containing only nonaromatic residues. Excitation of the S-S- n-cr transition between 280 and 290 nm leads to.ernission in the region 300-340 nm. The position and intensity of the emission band depends on the stereochemistry of the peptide and polarity of the solvent. Quantum yields

Disulfide-disulfide interchange catalyzed by a liver supernatant enzyme
Biochimica et Biophysica Acta (BBA) - Enzymology, 1979An enzyme widely distributed in rabbit tissues which catalyzes an interchange between N,N-di-dinitrophenyl-L-cystine and oxidized glutathione to form the mixed disulfide is described. D-Penicillamine disulfide can be substituted for oxidized glutathione and the mixed disulfide of cysteine and glutathione can serve as the sole substrate giving as one ...

Thiol-disulfide interchange reactions between serum albumin and disulfides
Biochimica et Biophysica Acta (BBA) - Protein Structure, 1969Abstract Thiol-disulfide interchange between serum albumins and l -cystine or lysine vasopressin was studied by p- chloromercuribenzoate (PCMB) titration and by incubation with radioactive disulfides followed by separation of reaction products using Sephadex G-15 gel filtration. Good agreement between these two techniques was obtained.

Disulfide Bond in Diethyl Disulfide: A Rotational Spectroscopic Study
The Journal of Physical Chemistry A, 2018Diethyl disulfide was investigated by pulsed jet Fourier transform microwave spectroscopy. The spectroscopic study was complemented by ab initio calculations. The first two most stable conformers predicted at the MP2/6-311++G(d,p) level of theory were observed in the supersonic expansion. Two 13C and one 34S isotopologues for the most stable conformer (
