Antibodies found applications in several fields, including, medicine, diagnostics, and nanotechnol., yet methods to modulate antibody-antigen binding using an external agent remain limited. Here, the authors have developed photoactive antibody fragments by genetic site-specific replacement of single tyrosine residues with photocaged tyrosine, in an antibody fragment, 7D12. A simple and robust assay is adopted to evaluate the light-mediated binding of 7D12 mutants to its target, epidermal growth factor receptor (EGFR), on the surface of cancer cells. Presence of photocaged tyrosine reduces 7D12-EGFR binding affinity by over 20-fold in two out of three 7D12 mutants studied, and binding is restored upon exposure to 365 nm light. Mol. dynamics simulations explain the difference in effect of photocaging on 7D12-EGFR interaction among the mutants. Finally, the authors demonstrate the application of photoactive antibodies in delivering fluorophores to EGFR-pos. live cancer cells in a light-dependent manner.

Knauer, Sascha; Koch, Niklas; Uth, Christina; Meusinger, Reinhard; Avrutina, Olga; Kolmar, Harald published an article in Angewandte Chemie, International Edition. The title of the article was 《Sustainable peptide synthesis enabled by a transient protecting group》.HPLC of Formula: 2418-95-3 The author mentioned the following in the article:

The growing interest in synthetic peptides has prompted the development of viable methods for their sustainable production Currently, large amounts of toxic solvents are required for peptide assembly from protected building blocks, and switching to water as a reaction medium remains a major hurdle in peptide chem. We report an aqueous solid-phase peptide synthesis strategy that is based on a water-compatible 2,7-disulfo-9-fluorenylmethoxycarbonyl (Smoc) protecting group. This approach enables peptide assembly under aqueous conditions, real-time monitoring of building block coupling, and efficient postsynthetic purification The procedure for the synthesis of all natural and several non-natural Smoc-protected amino acids is described, as well as the assembly of 22 peptide sequences and the fundamental issues of SPPS, including the protecting group strategy, coupling and cleavage efficiency, stability under aqueous conditions, and crucial side reactions.

《Glutamate-urea-based PSMA-targeted PLGA nanoparticles for prostate cancer delivery of docetaxel》 was published in Pharmaceutical Development and Technology in 2021. These research results belong to Saniee, Fateme; Shabani Ravari, Nazanin; Goodarzi, Navid; Amini, Mohsen; Atyabi, Fatemeh; Saeedian Moghadam, Ebrahim; Dinarvand, Rassoul. Product Details of 2418-95-3 The article mentions the following:

Targeted drug delivery is a tool to make treatment more specific, selective, and effective and to prevent unwanted complications. Prostate specific membrane antigen (PSMA) is a useful biomarker in order to monitor and control prostate cancer. Glutamate-Urea-R (Glu-Urea-R) is a PSMA enzyme inhibitor capable of binding to this surface marker of prostate cancer cell in an efficient and special manner. The aim of this project was to develop a docetaxel-loaded nanoparticle of poly (lactic-co-glycolic acid) polyethylene glycol which is cojugated to a urea-based anti-PSMA ligand named glutamate-urea-lysine (glu-urea-lys) for targeted delivery of docetaxel in prostate cancer. The obtained nanoparticles, prepared by nanopptn. method, were spheres with a particle size of around 150 nm and zeta potential of -7.08 mV. Uptake studies on the PC3 (as PSMA neg.) and LNCaP (as PSMA pos.) cells demonstrated that drug uptake was efficient by the PSMA pos. cells. IC50 of targeted NPs on LNCaP cell line compared to non-targeted ones was reduced by more than 70% in three different incubation times of 24, 48, and 72 h. In conclusion, the nanoparticles are expected to specifically transport docetaxel to PSMA-pos. prostate cancer cells and consequently, enhance the antitumor efficacy of docetaxel on these cells. In the experiment, the researchers used many compounds, for example, H-Lys(Boc)-OH(cas: 2418-95-3Product Details of 2418-95-3)

Morimoto, Mariko; Cao, Wendy; Bergman, Robert G.; Raymond, Kenneth N.; Toste, F. Dean published an article on February 3 ,2021. The article was titled 《Chemoselective and Site-Selective Reductions Catalyzed by a Supramolecular Host and a Pyridine-Borane Cofactor》, and you may find the article in Journal of the American Chemical Society.Recommanded Product: 2418-95-3 The information in the text is summarized as follows:

Supramol. catalysts emulate the mechanism of enzymes to achieve large rate accelerations and precise selectivity under mild and aqueous conditions. While significant strides have been made in the supramol. host-promoted synthesis of small mols., applications of this reactivity to chemoselective and site-selective modification of complex biomols. remain virtually unexplored. We report here a supramol. system where coencapsulation of pyridine-borane with a variety of mols. including enones, ketones, aldehydes, oximes, hydrazones, and imines effects efficient reductions under basic aqueous conditions. Upon subjecting unprotected lysine to the host-mediated reductive amination conditions, we observed excellent ε-selectivity, indicating that differential guest binding within the same mol. is possible without sacrificing reactivity. Inspired by the post-translational modification of complex biomols. by enzymic systems, we then applied this supramol. reaction to the site-selective labeling of a single lysine residue in an 11-amino acid peptide chain and human insulin. In addition to this study using H-Lys(Boc)-OH, there are many other studies that have used H-Lys(Boc)-OH(cas: 2418-95-3Recommanded Product: 2418-95-3) was used in this study.

Category: amides-buliding-blocksOn October 1, 2021 ,《Synthesis, antitumor activity and in silico analyses of amino acid derivatives of artepillin C, drupanin and baccharin from green propolis》 was published in Bioorganic & Medicinal Chemistry. The article was written by Rodrigues, Debora Munhoz; Portapilla, Gisele Bulhoes; Silva, Guilherme Martins; Duarte, Andressa; Rotta, Cristiana Goncalez; da Silva, Carlos Henrique Tomich de Paula; de Albuquerque, Sergio; Bastos, Jairo Kenupp; Campo, Vanessa Leiria. The article contains the following contents:

Breast cancer has the highest incidence and mortality in females, while prostate cancer has the second-highest incidence in males. Studies have shown that compounds from Brazilian green propolis have antitumor activities and can selectively inhibit the AKR1C3 enzyme, overexpressed in hormone-dependent prostate and breast tumors. Thus, in an attempt to develop new cytotoxic inhibitors against these cancers, three prenylated compounds, artepillin C, drupanin and baccharin, were isolated from green propolis to synthesize new derivatives via coupling reactions with different amino acids. All obtained derivatives were submitted to antiproliferative assays against four cancer cells (MCF-7, MDA MB-231, PC-3, and DU145) and two normal cell lines (MCF-10A and PNT-2) to evaluate their cytotoxicity. In general, the best activity was observed for compound 6e, derived from drupanin, which exhibited half-maximal inhibitory concentration (IC50) of 9.6 ± 3 μM and selectivity index (SI) of 5.5 against MCF-7 cells. In silico studies demonstrated that these derivatives present coherent docking interactions and binding modes against AKR1C3, which might represent a possible mechanism of inhibition in MCF-7 cells. The results came from multiple reactions, including the reaction of H-Lys(Boc)-OH(cas: 2418-95-3Category: amides-buliding-blocks)

Reference of H-Lys(Boc)-OHOn October 30, 2019 ,《Total Synthesis and Stereochemical Assignment of Streptide》 was published in Journal of the American Chemical Society. The article was written by Isley, Nicholas A.; Endo, Yusuke; Wu, Zhi-Chen; Covington, Brett C.; Bushin, Leah B.; Seyedsayamdost, Mohammad R.; Boger, Dale L.. The article contains the following contents:

Streptide is a peptide-derived macrocyclic natural product that has attracted considerable attention since its discovery in 2015. It contains an unprecedented post-translational modification that intramolecularly links the β-carbon (C3) of a residue 2 lysine with the C7 of a residue 6 tryptophan, thereby forming a 20-membered cyclic peptide. Herein, we report the first total synthesis of streptide that confirms the regiochem. of the lysine-tryptophan crosslink and provides an unambiguous assignment of the stereochem. (3R vs 3S) of the lysine-2 C3 center. Both the 3R and the originally assigned 3S lysine diastereomers were independently prepared by total synthesis and it is the former, not the latter, that was found to correlate with the natural product. The approach enlists a powerful Pd(0)-mediated indole annulation for the key macrocyclization of the complex core peptide, utilizes an underdeveloped class of hypervalent iodine(III) aryl substrates in a palladium-catalyzed C-H activation/β-arylation reaction conducted on a lysine derivative, and provides access to material with which the role of streptide and related natural products may be examined The experimental process involved the reaction of H-Lys(Boc)-OH(cas: 2418-95-3Reference of H-Lys(Boc)-OH)

Formula: C11H22N2O4On March 31, 2021, Morgan, Charles W.; Dale, Ian L.; Thomas, Andrew P.; Hunt, James; Chin, Jason W. published an article in Journal of the American Chemical Society. The article was 《Selective CRAF Inhibition Elicits Transactivation》. The article mentions the following:

Discovering mols. that regulate closely related protein isoforms is challenging, and in many cases the consequences of isoform-specific pharmacol. regulation remains unknown. RAF isoforms are commonly mutated oncogenes that serve as effector kinases in MAP kinase signaling. BRAF/CRAF heterodimers are believed to be the primary RAF signaling species, and many RAF inhibitors lead to a “”paradoxical activation”” of RAF kinase activity through transactivation of the CRAF protomer; this leads to resistance mechanisms and secondary tumors. It has been hypothesized that CRAF-selective inhibition might bypass paradoxical activation, but no CRAF-selective inhibitor has been reported and the consequences of pharmacol. inhibiting CRAF have remained unknown. Here, we use bio-orthogonal ligand tethering (BOLT) to selectively target inhibitors to CRAF. Our results suggest that selective CRAF inhibition promotes paradoxical activation and exemplify how BOLT may be used to triage potential targets for drug discovery before any target-selective small mols. are known.

The article was titled 《Synthesis of silacyclic dipeptides: Peptide elongation at both N- and C-termini of dipeptide》, and you may find the article in Journal of the American Chemical Society.Synthetic Route of C11H22N2O4 The information in the text is summarized as follows:

A new type of peptide bond formation utilizing silacyclic amino acids or peptides is described. This work has the following advantages: (1) imidazolylsilane is a highly fascinating coupling reagent for dipeptide synthesis from N-,C-terminal unprotected amino acids with amino acid tert-Bu esters; (2) deprotection of the tert-Bu ester at the C-terminus and cyclization sequentially proceed depending on reaction conditions to afford novel silacyclic dipeptides; (3) the cyclized products show a remarkable capacity as substrates of peptide elongation because the silacyclic compounds can act as both nucleophiles and electrophiles, and this capacity lead to one-pot site-selective tetra- and oligopeptide syntheses. These innovative advantages will help to simplify classical peptide synthesis significantly.

The article was 《Discovery of a novel family of FKBP12 “”reshapers”” and their use as calcium modulators in skeletal muscle under nitro-oxidative stress》. The article mentions the following:

The hypothesis of rescuing FKBP12/RyR1 interaction and intracellular calcium homeostasis through mol. “”reshaping”” of FKBP12 was investigated. To this end, novel 4-arylthioalkyl-1-carboxyalkyl-1,2,3-triazoles were designed and synthesized, and their efficacy was tested in human myotubes. A library of 17 compounds (10a-n) designed to dock the FKBP12/RyR1 hot-spot interface contact residues, was readily prepared from free α-amino acids and arylthioalkynes using CuAAC “”click”” protocols amenable to one-pot transformations in high overall yields and total configurational integrity. To model nitro-oxidative stress, human myotubes were treated with the peroxynitrite donor SIN1, and evidence was found that some triazoles 10 were able to normalize calcium levels, as well as FKBP12/RyR1 interaction. For example, compound 10 b at 150 nM rescued 46% of FKBP12/RyR1 interaction and up to 70% of resting cytosolic calcium levels in human myotubes under nitro-oxidative stress. All compounds 10 analyzed showed target engagement to FKBP12 and low levels of cytotoxicity in vitro. Compounds 10b, 10c, 10h, and 10iR were identified as potential therapeutic candidates to protect myotubes in muscle disorders with underlying nitro-oxidative stress, FKBP12/RyR1 dysfunction and calcium dysregulation.
