Residue-Based Preorganization of BH3-Derived α/β-Peptides: Modulating Affinity, Selectivity and Proteolytic Susceptibility in α-Helix Mimics was written by Peterson-Kaufman, Kimberly J.;Haase, Holly S.;Boersma, Melissa D.;Lee, Erinna F.;Fairlie, W. Douglas;Gellman, Samuel H.. And the article was included in ACS Chemical Biology in 2015.SDS of cas: 401915-53-5 This article mentions the following:

We report progress toward a general strategy for mimicking the recognition properties of specific α-helixes within natural proteins through the use of oligomers that are less susceptible than conventional peptides to proteolysis. The oligomers contain both α- and β-amino acid residues, with the d. of the β subunits low enough that an α-helix-like conformation can be adopted but high enough to interfere with protease activity. Previous studies with a different protein-recognition system that suggested ring-constrained β residues can be superior to flexible β residues in terms of maximizing α/β-peptide affinity for a targeted protein surface. Here, we use mimicry of the 18-residue Bim BH3 domain to expand the scope of this strategy. Two significant advances have been achieved. First, we have developed and validated a new ring-constrained β residue that bears an acidic side chain, which complements previously known analogs that are either hydrophobic or basic. Second, we have discovered that placing cyclic β residues at sites that make direct contact with partner proteins can lead to substantial discrimination between structurally homologous binding partners, the proteins Bcl-x_L and Mcl-1. Overall, this study helps to establish that α/β-peptides containing ring-preorganized β residues can reliably provide proteolytically resistant ligands for proteins that naturally evolved to recognize α-helical partners. In the experiment, the researchers used many compounds, for example, (S)-3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-6-(3-((2,2,4,6,7-pentamethyl-2,3-dihydrobenzofuran-5-yl)sulfonyl)guanidino)hexanoic acid (cas: 401915-53-5SDS of cas: 401915-53-5).

The development of donor-specific antibodies (DSA) after lung transplantation is common and results in adverse outcomes. In kidney transplantation, Belatacept has been associated with a lower incidence of DSA, but experience with Belatacept in lung transplantation is limited. We conducted a two-center pilot randomized controlled trial of de novo immunosuppression with Belatacept after lung transplantation to assess the feasibility of conducting a pivotal trial. Twenty-seven participants were randomized to Control (Tacrolimus, Mycophenolate Mofetil, and prednisone, n = 14) or Belatacept-based immunosuppression (Tacrolimus, Belatacept, and prednisone until day 89 followed by Belatacept, Mycophenolate Mofetil, and prednisone, n = 13). All participants were treated with rabbit anti-thymocyte globulin for induction immunosuppression. We permanently stopped randomization and treatment with Belatacept after three participants in the Belatacept arm died compared to none in the Control arm. Subsequently, two addnl. participants in the Belatacept arm died for a total of five deaths compared to none in the Control arm (log rank p = .016). We did not detect a significant difference in DSA development, acute cellular rejection, or infection between the two groups. We conclude that the investigational regimen used in this study is associated with increased mortality after lung transplantation. In the experiment, the researchers used many compounds, for example, (E)-6-(4-Hydroxy-6-methoxy-7-methyl-3-oxo-1,3-dihydroisobenzofuran-5-yl)-4-methylhex-4-enoic acid (cas: 24280-93-1Safety of (E)-6-(4-Hydroxy-6-methoxy-7-methyl-3-oxo-1,3-dihydroisobenzofuran-5-yl)-4-methylhex-4-enoic acid).

Synthesis of CoSnS₂ hollow nanocubes with NIR-enhanced chemodynamic therapy and glutathione depletion for combined cancer therapy was written by Zhu, Xuerui;Chu, Zhaoyou;Chen, Benjin;Jin, Qianqian;Ma, Xuke;Yang, Juan;Jiang, Yongxin;Wang, Wanni;Zha, Zhengbao;Qian, Haisheng. And the article was included in Materials Chemistry Frontiers in 2022.HPLC of Formula: 1461-15-0 This article mentions the following:

Low concentrations of endogenous hydrogen peroxide (H₂O₂) and intrinsic oxidative stress defense system greatly limited the efficiency of Fenton and Fenton-like reactions driven by a single metal element. Moreover, the complex physiol. environment and inherent self-healing function of tumors make it difficult for chemodynamic therapy (CDT) alone, driven by Fenton and Fenton-like reactions, to eliminate malignant tumors. Herein, a tumor microenvironment (TME) remodeling cobalt-stannous sulfide CoSnS2 (CSS) hollow nanocubes are presented for photothermal therapy (PTT)-improved CDT, in which two redox pairs (Co²⁺/Co³⁺ and Sn²⁺/Sn⁴⁺) are involved in catalyzing H₂O₂ to generate a large number of toxic hydroxyl radicals ( OH) resulting in massive apoptosis of tumor cells. Importantly, two redox pairs (Co²⁺/Co³⁺ and Sn²⁺/Sn⁴⁺) promoted the depletion of glutathione (GSH), which reduced tumor antioxidant capacity and thus enhanced the CDT therapeutic impact of CDT. Furthermore, the CDT efficiency was greatly improved by the excellent photothermal effect (η = 47.23%). The combination of PTT and CDT achieved good therapeutic effects, which may provide a new perspective for the development of other anti-tumor strategies on the basis of improved CDT and modulation of TME. In the experiment, the researchers used many compounds, for example, 2,2′,2”,2”’-(((3′,6′-Dihydroxy-3-oxo-3H-spiro[isobenzofuran-1,9′-xanthene]-2′,7′-diyl)bis(methylene))bis(azanetriyl))tetraacetic acid (cas: 1461-15-0HPLC of Formula: 1461-15-0).

Prucalopride for the treatment of ileus was written by Smart, Christopher J.;Malik, Kamran I.. And the article was included in Expert Opinion on Investigational Drugs in 2017.Related Products of 179474-81-8 This article mentions the following:

Postoperative ileus (POI) is an impairment of coordinated gastrointestinal (GI) motility that develops as a consequence of abdominal surgery and is a major factor contributing to patient morbidity and prolonged hospitalisation. Despite the availability of various options its treatment is still under debate. This review will focus on effect of Prucalopride (5-HT₄ receptor agonist) on postoperative ileus based on the existing literature. A literature search of MEDLINE, EMBASE and COCHRANE Library was performed concerning topics related to the treatment of ileus with prucalopride. The search strategy also included articles relating to other treatments of ileus for comparison with prucalopride. Postoperative ileus remains difficult to treat and most strategies encompass preventative measures through enhanced recovery after surgery and laparoscopic approaches. The role of pharmacol. intervention is developing with some drugs licensed for use. The evidence for prucalopride remains unclear although there is randomised controlled trial (RCT) evidence available. Given the potential for reduction in patient morbidity and length of stay the role of prucalopride in POI should be further investigated with multi-center RCTs to establish which group of patients will gain the most from this exciting potential treatment. In the experiment, the researchers used many compounds, for example, 4-Amino-5-chloro-N-(1-(3-methoxypropyl)piperidin-4-yl)-2,3-dihydrobenzofuran-7-carboxamide (cas: 179474-81-8Related Products of 179474-81-8).
