Advances and perspectives in carrier-free nanodrugs for cancer chemo-monotherapy and combination therapy. Cysteine sulfenic acid has a number of biological functions. The PDIs function to shuffle disulfide bonds, stabilize proper intermediates, and resolve aberrant disulfide bonds via a thiol-disulfide exchange reaction, with the transient formation of mixed disulfide bond between PDI and its substrate protein (Figure 2). Xueli Zhao, Shuang-Quan Zang, Xiaoyuan Chen. But in the absence of a nearby second cysteine, thiol oxidation typically leads to the formation of sulfenic acid (S–OH), sulfinic acid (SO 2H), S-nitrosothiols (S– NO), or S-glutathione (S–SG). Smart Magnetic and Fluorogenic Photosensitizer Nanoassemblies Enable Redox‐Driven Disassembly for Photodynamic Therapy. Here, the oxidation state of sulfur is changed from − 2 - 2 − 2 to − In biochemistry, the terminology R-S-S-R connectivity is commonly used to describe the overall linkages.

Precise nanomedicine for intelligent therapy of cancer. In bacteria, disulfide bonds in bioactive peptides and polypeptides of the secretory pathway are formed in the periplasm; in eukaryotes, such (poly)peptides tend to acquire their disulfide bonds in the endoplasmic reticulum (ER) although disulfide bond formation can occasionally occur at other sites (including extracellularly). Disulfide bonds stabilize protein structure by organizing and destabilizing the denatured protein relative to the native structure.

Probing the Superiority of Diselenium Bond on Docetaxel Dimeric Prodrug Nanoassemblies: Small Roles Taking Big Responsibilities. AEMTS blocking facilitates the subsequent fractionation (by adding a positively charged cysteamine group for every blocked thiol) and does not require the maintenance of low pH during the subsequent analysis. In vivo Shou-Yuan Sung, Yu-Lin Su, Wei Cheng, Pei-Fan Hu, Chi-Shiun Chiang, Wen-Ting Chen. Information. Files available from the ACS website may be downloaded for personal use only. thioredoxins and glutaredoxins). The formation of disulfide bonds between the correct pairs of cysteine residues is essential for the folding and stability of many proteins (Narayan et al. The formation of an intramolecular disulfide bond between cysteines C38 and C83 enhances the nitrite reductase activity by 50-fold over that of the monomer with free sulfhydryl or 140-fold over that of the dimer with intermolecular disulfide bonds. As the two atoms of hydrogen are lost by thiol to make a disulfide bond, through the oxidation of carbonic acid or nitric acid it further attains oxygens to form sulfones that succeed towards the formation of sulfonic acid. oxidative stress response).

Yingli Wang, Jiamei Wang, Liyuan Yang, Wei Wei, Bingjun Sun, Kexin Na, Yuxi Song, Haotian Zhang, Zhonggui He, Jin Sun, Yongjun Wang. Disulfide-bond regeneration can be arrested at different times, either by acid quenching or by a rapid thiol-blocking agent such as aminoethylmethane thiosulfonate (AEMTS)154 and similar thiosulfonates. Abstract Disulfide bonds have been widely used to develop reduction-responsive drug-delivery systems (DDS) for cancer therapy. system. Tables showing the characterization of prodrug nanoassemblies, cytotoxicity, and pharmacokinetic parameters. Chutong Tian, Jingjing Guo, Gang Wang, Bingjun Sun, Kexin Na, Xuanbo Zhang, Zhuangyan Xu, Maosheng Cheng, Zhonggui He, Jin Sun. Disulfide bond formation involves a reaction between the sulfhydryl (SH) side chains of two cysteine residues: an S− anion from one sulfhydryl group acts as a nucleophile, attacking the side chain of a second cysteine to create a disulfide bond, and in the process releases electrons (reducing equivalents) for transfer. Electronic Supporting Information files are available without a subscription to ACS Web Editions. Cysteine sulfenic acid (–SOH) is the initial product of oxidation of cysteine by cellular reactive oxygen species such as hydrogen peroxide. The reaction was carried for 15 min at 4 °C under stirring, and the excess dye removed by TCA precipitation. In BEST1, five Cys residues in their corresponding positions 23, 42, 69, 221, and 251 were involved in disulfide bond formation between 221 and 251 and 23 and 42. 4). The redox state of the cytoplasm of eukaryotic and prokaryotic cells is reducing due to the presence of numerous disulfide bond reductases (e.g. The PDI was initially discovered by Christian Anfinsen as an ER enzyme that facilitates the … More interestingly, the position of disulfide bonds in the carbon chain linkage has profound impacts on the redox dual responsiveness, thereby affecting the drug release, cytotoxicity, pharmacokinetics, biodistribution, and in vivo antitumor efficacy of prodrug nanoassemblies. This feature is incredibly rare among proteins, as nearly all proteins are stabilized by the formation of disulfide bonds. Efficient Intestinal Digestion and On Site Tumor‐Bioactivation are the Two Important Determinants for Chylomicron‐Mediated Lymph‐Targeting Triglyceride‐Mimetic Docetaxel Oral Prodrugs. Disulfide bonds can also serve catalytic (e.g. Additional details on the experimental methods. Because disulfide bond formation is reversible, disulfide bonds can also regulate biological activity through their ability to stabilize specific protein structures.

Japir, Fathelrahman Mohammed, Yi Wang, Yueyin Pan. Sena Karaosmanoglu, Mengjiao Zhou, Bingyang Shi, Xiujuan Zhang, Gareth R. Williams, Xianfeng Chen. Thus, the disulfide formed during translation has to be reduced and re-oxidized and the early formation of a non-native disulfide will catalyze disulfide bond isomerization once the polypeptide chain is released (Fig. Yang Li, Yuwen Chen, Yulan Huang, Wenbi Wu, Yu Liu, Jing Zhang, Meijuan Huang, Maling Gou. This occurs as a protein-based relay of oxidation/reduction reactions, involving, for example, a PDI and the oxidoreductases Ero1 (associated with the ER membrane). Liying Wang, Xinru You, Qi Lou, Siyu He, Junfu Zhang, Chunlei Dai, Meng Zhao, Minyi Zhao, Hai Hu, Jun Wu. The most common way of creating this bond is by the oxidation of sulfhydryl groups. Liyi Fu, Fengming Zou, Qingwang Liu, Beilei Wang, Junqing Wang, Huamin Liang, Xiaofei Liang, Jing Liu, Jinjun Shi, Qingsong Liu. Jianhui Yuan, Qi Zhou, Xuelin Dong, Binbin Zhang, Qin Wang, Yajiang Yang, Yonggui Liao, Hong Wang. The ER is a vastly more common site than the cytosol (which is very rarely the site of disulfide bond formation) because the ER intralumenal environment is more oxidizing than that of the cytosol.1 The redox environment is at least partly reflected by the ratio of oxidized glutathione (GSSG) to reduced glutathione (GSH), which in the case of the ER (and periplasm), is shifted in favor of GSSG.1, Z. Chang, in Encyclopedia of Cell Biology, 2016. Nanotherapeutics for Antimetastatic Treatment. Proteins Using High-Resolution NMR: A Study of Disulfide Bond Compensation Andria L. Skinner1 and Jennifer S. Laurence1,* 1Department of Pharmaceutical Chemistry, The University of Kansas, Lawrence, KS 66047 Abstract It is well established that the oxidation state of cysteine residues in proteins are critical to overall physical stability. Glutathione-sensitive PEGylated curcumin prodrug nanomicelles: Preparation, characterization, cellular uptake and bioavailability evaluation. DsbA's highly oxidizing nature is a result of hydrogen bond, electrostatic and helix-dipole interactions that favour the thiolate over the disulfide at the active site. If the blocking of thiols is too slow, the blocking agent may act as an oxidizing agent; the unblocked thiols may attack the disulfide bond of the blocked thiols and form an intraprotein disulfide bond. Bin Yang, Lin Wei, Yuequan Wang, Na Li, Bin Ji, Kaiyuan Wang, Xuanbo Zhang, Shenwu Zhang, Shuang Zhou, Xiaohui Yao, Hang Song, Yusheng Wu, Haotian Zhang, Qiming Kan, Tao Jin, Jin Sun. These metrics are regularly updated to reflect usage leading up to the last few days. 6 Kinetic control by limiting glutaredoxin amounts enables thiol oxidation in the reducing mitochondrial intermembrane space (2 RSH → RS-SR + 2 H+ + 2 e-) This process of oxidation can produce stable protein dimers, polymers, or complexes, in which the sulfide bonds can help in protein folding. Compounds containing a disulfide bridge are able to undergo disulfide exchange reactions (also called “interchange”) with thiols. A light-induced nitric oxide controllable release nano-platform based on diketopyrrolopyrrole derivatives for pH-responsive photodynamic/photothermal synergistic cancer therapy. & Account Managers, For Under these conditions, the cytosolic copper chaperone Atox1, which delivers Cu(I) to the secretory pathway, gets oxidized, i.e., a disulfide bond is formed between the cysteine residues of the Cu(I)-binding CxxC motif. of metformin. Zhiqiang Zhao, Fujun Yang, Xuanbo Zhang, Jin Sun, Zhonggui He, Cong Luo. The redox dual-responsive mechanism is elucidated, and how the position of disulfide bonds in the carbon chain affects the redox dual responsiveness and antitumor efficiency of prodrug nanoassemblies is also clarified. The disulfide bonds, often present in secretory proteins and virtually absent in cytosolic proteins, are formed in the ER lumen where a relatively high oxidative redox potential is commonly maintained and PDIs are abundant (Braakman and Bulleid, 2011). in vitro Self-facilitated ROS-responsive nanoassembly of heterotypic dimer for synergistic chemo-photodynamic therapy.
