On March 1, 2021, Zhang, Liang; Nagaraju, Sakkani; Paplal, Banoth; Lin, Yunliang; Liu, Shuhua published an article.Reference of 3-Acetyldihydrofuran-2(3H)-one The title of the article was Sulfonium Salts Enable the Direct Sulfenylation of Activated C(sp3)-H Bonds. And the article contained the following:

Herein, the direct α-sulfenylation of a series of β-dicarbonyl, β-ketophosphonate, and β-ketonitrile compounds, mediated by sulfonium salts has been described. Traditionally, sulfonium salts which are synthesized by activation of dialkylsulfoxides serve as oxidizing agents or precursors of sulfur ylide. In this transformation, sulfonium salts as readily prepared and operationally simple sulfenylation reagents firstly achieved alkylsulfenylation of various activated C(sp3)-H bonds with the formation of tetra-substituted carbon center. Thus, e.g., sulfenylation of Me 2-oxocyclopentanecarboxylate with DMSO in presence of AcCl as activator and NaSbF6 in MeCN afforded I (79%). The experimental process involved the reaction of 3-Acetyldihydrofuran-2(3H)-one(cas: 517-23-7).Reference of 3-Acetyldihydrofuran-2(3H)-one

Chen, Wei-Hai; Yu, Xu; Liao, Wei-Ching; Sohn, Yang Sung; Cecconello, Alessandro; Kozell, Anna; Nechushtai, Rachel; Willner, Itamar published an article in 2017, the title of the article was ATP-Responsive Aptamer-Based Metal-Organic Framework Nanoparticles (NMOFs) for the Controlled Release of Loads and Drugs.Application of 1312703-30-2 And the article contains the following content:

Nanoparticles consisting of metal-organic frameworks (NMOFs) modified with nucleic acid binding strands are synthesized. The NMOFs are loaded with a fluorescent agent or with the anticancer drug doxorubicin, and the loaded NMOFs are capped by hybridization with a complementary nucleic acid that includes the ATP-aptamer or the ATP-AS1411 hybrid aptamer in caged configurations. The NMOFs are unlocked in the presence of ATP via the formation of ATP-aptamer complexes, resulting in the release of the loads. As ATP is overexpressed in cancer cells, and since the AS1411 aptamer recognizes the nucleolin receptor sites on the cancer cell membrane, the doxorubicin-loaded NMOFs provide functional carriers for targeting and treatment of cancer cells. Preliminary cell experiments reveal impressive selective permeation of the NMOFs into MDA-MB-231 breast cancer cells as compared to MCF-10A normal epithelial breast cells. High cytotoxic efficacy and targeted drug release are observed with the ATP-AS1411-functionalized doxorubicin-loaded NMOFs. The experimental process involved the reaction of Dimethyl 2′-amino-[1,1′:4′,1”-terphenyl]-4,4”-dicarboxylate(cas: 1312703-30-2).Application of 1312703-30-2

On April 9, 2014, He, Chunbai; Lu, Kuangda; Liu, Demin; Lin, Wenbin published an article.Related Products of 1312703-30-2 The title of the article was Nanoscale Metal-Organic Frameworks for the Co-Delivery of Cisplatin and Pooled siRNAs to Enhance Therapeutic Efficacy in Drug-Resistant Ovarian Cancer Cells. And the article contained the following:

Ovarian cancer is the leading cause of death among women with gynecol. malignancies. Acquired resistance to chemotherapy is a major limitation for ovarian cancer treatment. We report here the first use of nanoscale metal-organic frameworks (NMOFs) for the co-delivery of cisplatin and pooled small interfering RNAs (siRNAs) to enhance therapeutic efficacy by silencing multiple drug resistance (MDR) genes and resensitizing resistant ovarian cancer cells to cisplatin treatment. UiO NMOFs with hexagonal-plate morphologies were loaded with a cisplatin prodrug and MDR gene-silencing siRNAs (Bcl-2, P-glycoprotein [P-gp], and survivin) via encapsulation and surface coordination, resp. NMOFs protect siRNAs from nuclease degradation, enhance siRNA cellular uptake, and promote siRNA escape from endosomes to silence MDR genes in cisplatin-resistant ovarian cancer cells. Co-delivery of cisplatin and siRNAs with NMOFs led to an order of magnitude enhancement in chemotherapeutic efficacy in vitro, as indicated by cell viability assay, DNA laddering, and Annexin V staining. This work shows that NMOFs hold great promise in the co-delivery of multiple therapeutics for effective treatment of drug-resistant cancers. The experimental process involved the reaction of Dimethyl 2′-amino-[1,1′:4′,1”-terphenyl]-4,4”-dicarboxylate(cas: 1312703-30-2).Related Products of 1312703-30-2

Mukerjee, Anindita; Ranjan, Amalendu P.; Vishwanatha, Jamboor K. published an article in 2014, the title of the article was Non-covalent surface integration: optimising a novel technique for preparing targeted polymeric nanoparticles for cancer therapeutics.SDS of cas: 79642-50-5 And the article contains the following content:

Targeting anticancer drugs to their specific mol. targets is a major challenge in cancer therapy. However, advances in biomedical and protein engineering have led to novel nanoparticle targeting approaches. In this study, we used a novel non-covalent insertion of a homo-bifunctional spacer for targeted delivery of drugs to various cancer cells. Functionalised blank nanoparticles for antibody (targeting agent) conjugation were prepared using different crosslinking spacers (bis[sulfosuccinimidyl] suberate (BS3), Disuccinimidyl glutarate (DSG) and sulfo-N-[ε-maleimidocaproyloxy] sulfosuccinimide ester (s-EMCS)). The concentration of the spacers and the concentration of antibody used for conjugation were optimized using flow cytometry. The optimized and functionalised nanoparticles thus obtained were characterised for percent yield, mean particle size, surface morphol. and percent antibody attachment. Our studies showed the formation of smooth and spherical functionalised poly(D,L-lactide-co-glycolide) (PLGA) nanoparticles which could be successfully conjugated to an antibody, Anti-Annexin A2, for targeting to breast cancer cells. The functionalisation of PLGA nanoparticles for antibody attachment was effectively optimized leading to high percent attachments of 92.8% achieved with BS3. Antibody conjugated PLGA nanoparticles were then evaluated for their targeting potential. Robust intra-cellular uptake of the targeted nanoparticles was observed in breast cancer cell line and in mouse xenograft tumor studies. Our results thus validate that such a novel technique of surface integration may be used for preparing targeted polymeric nanoparticles for cancer therapeutics. The experimental process involved the reaction of Bis(2,5-dioxopyrrolidin-1-yl) glutarate(cas: 79642-50-5).SDS of cas: 79642-50-5
