The Tn antigen is a well-known tumor-associated carbohydrate determinant, often incorporated in glycopeptides to develop cancer vaccines. Herein, four copies of a conformationally constrained mimetic of the antigen TnThr (GalNAc-Thr) were conjugated to the adjuvant CRM197, a protein licensed for human use. The resulting vaccine candidate, mime[4]CRM elicited a robust immune response in a triple-neg. breast cancer mouse model, correlated with high frequency of CD4+ T cells and low frequency of M2-type macrophages, which reduces tumor progression and lung metastasis growth. Mime[4]CRM-mediated activation of human dendritic cells is reported, and the proliferation of mime[4]CRM-specific T cells, in cancer tissue and peripheral blood of patients with breast cancer, is demonstrated. The locked conformation of the TnThr mimetic and a proper presentation on the surface of CRM197 may explain the binding of the conjugate to the anti-Tn antibody Tn218 and its efficacy to fight cancer cells in mice.

《Modular Design of Stimuli-Responsive Supramolecular Nanocarriers Based on Pro-Guest Strategy》 was published in ChemNanoMat in 2020. These research results belong to Mao, Weipeng; Yang, Xuan; Ma, Da. Quality Control of N-Boc-1,6-Diaminohexane The article mentions the following:

High affinity host-guest interactions were used to assemble supramol. nanocarriers, and controlled release cargo based on a “”pro-guest”” strategy. Supramol. nanocarriers were prepared by modular design, which were responsive to photo-irradiation or reducing agents. Model cargo nile red was stably encapsulated by nanocarriers in water, and released when photo-irradiation or reducing agent was applied. Cargo release rate was tunable by using different pro-guests for photo-responsive nanocarriers. A mechanistic study was carried out to confirm a cascade process of stimuli-responsive pro-guest degradation and competitive displacement. Supramol. nanocarriers were able to deliver model cargo to the cell cytoplasm. In addition to this study using N-Boc-1,6-Diaminohexane, there are many other studies that have used N-Boc-1,6-Diaminohexane(cas: 51857-17-1Quality Control of N-Boc-1,6-Diaminohexane) was used in this study.

《Unusual amino acids VI. Substituted arylamino acids by asymmetric hydrogenation of N-Cbz and N-Boc protected dehydroamino acid derivatives》 was published in Chirality in 1996. These research results belong to Krause, H. W.; Kreuzfeld, H.-J.; Schmidt, U.; Dobler, Ch.; Michalik, M.; Taudien, S.; Fischer, Ch.. Category: esters-buliding-blocks The article mentions the following:

Substituted N-Cbz and N-Boc protected (arylamino)acrylic acids and esters were prepared and used in asym. hydrogenations catalyzed by PROPRAPHOS-Rh. Stereoselectivities >90% ee could be achieved, the rate of which is dependent on the position of the substituent in the aromatic ring. The N-Boc derivatives provide advantages compared with the N-Cbz analogs. The amino acid derivatives were fully characterized by 19F, 13C, and 1H NMR. In the part of experimental materials, we found many familiar compounds, such as H-D-Phe(4-NO2)-OMe.HCl(cas: 67877-95-6Category: esters-buliding-blocks)

H-D-Phe(4-NO2)-OMe.HCl(cas: 67877-95-6) belongs to esters. Esters are more polar than ethers but less polar than alcohols. Category: esters-buliding-blocks They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.

The article was titled 《Preliminary study of a 1,5-benzodiazepine-derivative labelled with indium-111 for CCK-2 receptor targeting》, and you may find the article in Molecules.Recommanded Product: 51857-17-1 The information in the text is summarized as follows:

A nastorazepide-based ligand functionalized with a 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) chelator (IP-001) was synthesized and labeled with indium-111. The radiolabeling process yielded >95% with a molar activity of 10 MBq/nmol and a radiochem. purity of >98%. Stability studies showed a remarkable resistance to degradation (>93%) within 120 h of incubation in human blood. The in-vitro uptake of [111In]In-IP-001 was assessed for up to 24 h on a high CCK-2R-expressing tumor cell line (A549) showing maximal accumulation after 4 h of incubation. Biodistribution and single photon emission tomog. (SPECT)/CT imaging were evaluated on BALB/c nude mice bearing A549 xenograft tumors. Implanted tumors were clearly visualized after only 4 h post injection (2.36 ± 0.26% ID/cc), although a high amount of radiotracer was also found in the liver, kidneys, and spleen (8.25 ± 2.21%, 6.99 ± 0.97%, and 3.88 ± 0.36% ID/cc, resp.). Clearance was slow by both hepatobiliary and renal excretion. Tumor retention persisted for up to 24 h, with the tumor to organs ratio increasing over-time and ending with a tumor uptake (1.52 ± 0.71% ID/cc) comparable to liver and kidneys.

Morris, David T. J.; Wales, Steven M.; Tilly, David P.; Farrar, Elliot H. E.; Grayson, Matthew N.; Ward, John W.; Clayden, Jonathan published an article in 2021. The article was titled 《A molecular communication channel consisting of a single reversible chain of hydrogen bonds in a conformationally flexible oligomer》, and you may find the article in Chem.Related Products of 51644-96-3 The information in the text is summarized as follows:

Communication of information through the global switching of conformation in synthetic mols. has hitherto entailed the inversion of chirality. Here, we report a class of oligomer through which information may be communicated through a global reversal of polarity. Ethylene-bridged oligoureas are constitutionally sym., conformationally flexible mols. organized by a single chain of hydrogen bonds running the full length of the oligomer. NMR reveals that this hydrogen-bonded chain may undergo a coherent reversal of directionality. The directional uniformity of the hydrogen-bond chain allows it to act as a channel for the spatial communication of information on a mol. scale. A binding site at the terminus of an oligomer detects local information about changes in pH or anion concentration and transmits that information-in the form of a directionality switch in the hydrogen-bond chain-to a remote polarity-sensitive fluorophore. This propagation of polarity-encoded information provides a new mechanism for mol. communication.

Electric Literature of C10H12O4SOn March 26, 2022, Li, Xiaotong; Wang, Yu; Yang, Liqun; Zhang, Zhaoguo; Xie, Xiaomin published an article in Tetrahedron. The article was 《Visible-light-promoted aerobic oxidation of sulfides and sulfoxides in ketone solvents》. The article mentions the following:

Simple and readily available ketones have been identified to promote the visible-light-promoted aerobic oxidation of sulfides and sulfoxides to sulfones. A simple and environmental-friendly oxidation protocol of sulfides to sulfones is reported. Various sulfides were efficiently oxidized into sulfones with O2 as sustainable terminate oxidant, readily available thioxanthone as the photocatalyst and 3-pentanone (DEK) as the solvent. The protocol tolerates diverse functional groups, including halogens, ketone, ester, cyano, heterocycle and even cyclopropyl groups. The detection of the aerobic oxidation reaction in DEK by GC and HRMS disclosed that the key active intermediates were generated.
