Preparation of photoreactive derivatives of glutathione and [9-(2-mercaptotryptophan)]corticotropin by selective modification of the sulfhydryl group.

The photoreactive arylsulfenyl chlorides 2-nitro-4-azidophenylsulfenyl chloride (2,4-NAPS-Cl) and 2-nitro-5-azidophenylsulfenyl chloride (2,5-NAPS-Cl) have been used for the selective modification of thiol groups in glutathione and [Trp(SH)9]corticotropin (ACTH). Both reagents reacted rapidly with both types of thiol groups to form unsymmetrical disulfides. The photoreactive derivatives of glutathione and [Trp(SH)9]ACTH were stable to neutral and acidic conditions but were readily cleaved above pH 9 and by beta-mercaptoethanol. Photolysis of the NAPS derivatives of [Trp(SH)9]-ACTH at neutral pH resulted in the formation of covalently liked polymers and dimers which yielded monomer upon treatment with beta-mercaptoethanol. Analysis of the amino acid composition of acid hydrolysates of photolysed monomeric and dimeric products indicated a decrease in proline, valine, tyrosine, and phenylalanine.

Spontaneous [2,3]-sigmatropic rearrangement of s-arylthiosulfonium ylids formed in the reaction of arylsulfenyl chlorides with methylthiolyiethyltrimethylsilane

A new [2,3]-sigmatropic rearrangement of thiosulfonlum ylids yields ortho-methylthiomethyllhiophenols. The ylids were generated through the cleavage of a C-Si bond with chloride anion.

Photoreactive derivatives of corticotropin. 2. Preparation and characterization of 2-nitro-4(5)-azidophenylsulfenyl derivatives of corticotropin.

Two new photoreactive arylsulfenyl chlorides, 2-nitro-4-azidophenylsulfenyl chloride (2,4-NAPS-Cl) and 2-nitro-5-azidophenylsulfenyl chloride (2,5-NAPS-Cl), have been synthesized and used for the selective modification of corticotropin (ACTH). Both reagents reacted rapidly with N-acetyltryptophanamide and ACTH under acidic conditions. The NAPS derivatives of ACTH were purified by partition chromatography and characterized by absorption spectra, amino acid analysis, and peptide mapping. The spectral changes caused by photolysis as well as the kinetics of photolysis are described. Tritiated 2,5-NAPS-ACTH was attached covalently to a pituitary protein fraction FI by photolysis. The photolabeling of FI was blocked in the presence of excess ACTH.

Nucleophilic addition of sulfenyl chlorides to highly electrophilic fluoroolefins

1. When catalyzed by chlorine anion or pyridine, alkyl- or arylsulfenyl chlorides add to perfluoroisobutylene or to methyl perfluoromethacrylate by the nucleophilic mechanism. 2. Perfluoroisobutylene when reacted with either trichloromethyl- or chlorocarbonylsulfenyl chloride in the presence of chlorine anion adds chlorine at the multiple bond.

The Addition of 4-Chloro- and 2,4-Dinitrobenzenesulfenyl Chloride to cis- and trans-1-Phenylpropene

The thero-anti-Markownikoff and threo-Markownikoff adducts are the products of addition of 4-chloro-and 2,4-dinitrobenzenesulfenyl chloride to cis-1-phenylpropene while only the erythro Markownikoff adduct is the product of addition to trans-1-phenylpropene. The addition reaction follows second order kinetics, first order in both olefin and arylsulfenyl chloride, with the rate of addition to the trans-olefin faster than to the cis. These results are consistent with a mechanism involving bridged transition states in both the rate and product determining steps.

Nuclear quadrupole resonance spectra of some arylsulfenyl chlorides

1. The NQE frequencies are connected with the constants of para substitutents by the equationν=37.25 + 2.04σI+1.23σR, whereσI is the induction constant andσR the conjugation constant. 2. A nitro group interacts with the sulfur atom, considerably lowering the NQR frequency of the chlorine in the SCI group.

2-[2′-Methyl-4′-aminopyrimidyl-(5′)]-methylformamino-5-hydroxy-Δ2-pentenylaryl disulfides (thiamine aryl disulfides) were prepared by the application of arylsulfenyl chloride, aryl arylthiosulfonate, and aryl thiothiocyanate to the thiol type of vitamin B1, and homothiamine aryl disulfides were prepared in the same manner using homovitamin B1. Thiamine alkyl disulfides were obtained from the thiol type vitamin B1 and alkyl-sulfenyl chloride and alkyl or aralkyl thiosulfonate.
