Using a furanylthiazoleacetic acid as a starting point, a novel series of benzoxazol-5-ylacetic acid derivatives have been identified as heparanase inhibitors. Several compounds, such as I, possess an IC₅₀ of 鈭?00 nM against heparanase. Several of the compounds show antiangiogenic properties. Improvement to the DMPK profile has provided compounds of potential use in in vivo models. In the experiment, the researchers used many compounds, for example, 3-Cyanobenzoyl chloride (cas: 1711-11-1Product Details of 1711-11-1).

3-Cyanobenzoyl chloride (cas: 1711-11-1) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Product Details of 1711-11-1

And the article was included in Journal of Inorganic Biochemistry in 2009.COA of Formula: C8H8Cl2N4 This article mentions the following:

The 1st [Pd(Lⁿ)₂(ox)]xH₂O oxalato (ox) complexes involving 2-chloro-N6-(benzyl)-9-isopropyladenine (L¹; complex 1), 2-chloro-N6-(4-methoxybenzyl)-9-isopropyladenine (L²; 2), 2-chloro-N6-(2,3-dimethoxybenzyl)-9-isopropyladenine (L³; 3), 2-chloro-N6-(2,4-dimethoxybenzyl)-9-isopropyladenine (L⁴; 4), and 2-chloro-N6-(4-methylbenzyl)-9-isopropyladenine (L⁵; 5) were synthesized by the reactions of potassium bis(oxalato)palladate(II) dihydrate, [K₂Pd(ox)₂]路2H₂O, with the mentioned organic compounds (H₂ox = oxalic acid; x = 0 for 1–3 and 5 or 2 for 4). Elemental analyses (C, H, N), FTIR, Raman and NMR (¹H, ¹³C, ¹⁵N) spectroscopies, conductivity measurements and thermal studies (TGA and DTA, TG/DTA) were used to characterize the prepared complexes. The mol. structures of [Pd(L²)₂(ox)] (2) and [Pd(L⁵)₂(ox)]路L⁵路Me₂CO (5路L⁵路Me₂CO) were determined by a single crystal x-ray anal. The geometry of these complexes is slightly distorted square-planar with two appropriate Lⁿ (n = 2 or 5) mols. mutually arranged in the head-to-head (2) or head-to-tail (5) orientation. The Lⁿ ligands are coordinated to the central Pd(II) ion via the N7 atoms. The same conclusions regarding the binding properties of L¹-L⁵ ligands can be made based on multinuclear NMR spectra. In vitro cytotoxicity of the complexes 1–5 was evaluated against human chronic myelogenous leukemia (K562) and human breast adenocarcinoma (MCF7) cancer cell lines. Significant cytotoxicity was determined for the complexes 3 (IC₅₀ = 6.2 渭M) and 5 (IC₅₀ = 6.8 渭M) on the MCF7 cell line, which is even better than that found for the known and widely-used platinum-bearing antineoplastic drugs, i.e. oxaliplatin and cisplatin. In the experiment, the researchers used many compounds, for example, 2,6-Dichloro-9-isopropyl-9H-purine (cas: 203436-45-7COA of Formula: C8H8Cl2N4).

The purpose of this study was to evaluate the antibacterial and antibiotic-modulating activities of 1,8-naphthyridine derivatives against multi-resistant bacterial strains. The broth microdilution method was used to determine the min. inhibitory concentration (MIC) of the following compounds: 7-acetamido-1,8-naphthyridin-4(1H)-one and 3-trifluoromethyl-N-(5-chloro-1,8-naphthyridin-2-yl)-benzenesulfonamide. The antibiotic-modulating activity was analyzed using subinhibitory concentrations (MIC/8) of these compounds in combination with norfloxacin, ofloxacin, and lomefloxacin. Multi-resistant strains of Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus were used in both tests. Although the compounds had no direct antibacterial activity (MIC 鈮?1.024渭g/mL), they decreased the MIC of these fluoroquinolones, indicating synergism was obtained from the association of the compounds These results suggested the existence of a structure-activity relationship in this group of compounds with regard to the modulation of antibiotic activity. Therefore, concluded that 1,8-naphthyridine derivatives potentiate the activity of fluoroquinolone antibiotics against multi-resistant bacterial strains, and thereby interesting candidates for the development of drugs against bacterial infections caused by multidrug resistant strains. In the experiment, the researchers used many compounds, for example, 3-(Trifluoromethyl)benzene-1-sulfonyl chloride (cas: 777-44-6Category: chlorides-buliding-blocks).

Tuning Side Arm Electronics in Unsymmetrical Cyclotriazadisulfonamide (CADA) Endoplasmic Reticulum (ER) Translocation Inhibitors to Improve their Human Cluster of Differentiation 4 (CD4) Receptor Down-Modulating Potencies was written by Chawla, Reena;Van Puyenbroeck, Victor;Pflug, Nicholas C.;Sama, Alekhya;Ali, Rameez;Schols, Dominique;Vermeire, Kurt;Bell, Thomas W.. And the article was included in Journal of Medicinal Chemistry in 2016.Application In Synthesis of 4-Butoxybenzene-1-sulfonyl chloride This article mentions the following:

Cyclotriazadisulfonamide prevents HIV entry into cells by down-modulating surface CD4 receptor expression through binding to the CD4 signal peptide. According to a two-site binding model, 28 new unsym. analogs bearing a benzyl tail group and nine bearing a cyclohexylmethyl tail have been designed and synthesized. The most potent new CD4 down-modulator (40 (CK147); IC₅₀ 63 nM) has a 4-dimethylaminobenzenesulfonyl side arm. One of the two side arms was varied with substituents in different positions. This gave a range of CD4 down-modulation potencies that correlated well with anti-HIV-1 activities. The side arms of 21 of the new benzyl-tailed analogs were modeled by means of quantum mech. calculations For CADA analogs with arenesulfonamide side arms, the pIC₅₀ values for CD4 down-modulation correlated with the component of the elec. dipole moment in the aromatic ring, suggesting that an attractive electronic interaction is a major factor determining the stability of the complex between the mol. and its target.

N-Arylsulfonyl Indolines as Retinoic Acid Receptor-Related Orphan Receptor 纬 (ROR纬) Agonists was written by Doebelin, Christelle;Patouret, Remi;Garcia-Ordonez, Ruben D.;Chang, Mi Ra;Dharmarajan, Venkatasubramanian;Kuruvilla, Dana S.;Novick, Scott J.;Lin, Li;Cameron, Michael D.;Griffin, Patrick R.;Kamenecka, Theodore M.. And the article was included in ChemMedChem in 2016.Related Products of 777-44-6 This article mentions the following:

The nuclear retinoic acid receptor-related orphan receptor 纬 (ROR纬; NR1F3) is a key regulator of inflammatory gene programs involved in T helper 17 (T_H17) cell proliferation. As such, synthetic small-mol. repressors (inverse agonists) targeting ROR纬 have been extensively studied for their potential as therapeutic agents for various autoimmune diseases. Alternatively, enhancing T_H17 cell proliferation through activation (agonism) of ROR纬 may boost an immune response, thereby offering a potentially new approach in cancer immunotherapy. Herein the authors describe the development of N-arylsulfonyl indolines as ROR纬 agonists. Structure-activity studies reveal a critical linker region in these mols. as the major determinant for agonism. Hydrogen/deuterium exchange coupled to mass spectrometry (HDX-MS) anal. of ROR纬-ligand complexes help rationalize the observed results.

An integrated screening strategy for novel AhR agonist candidate identification and toxicity confirmation in sediments was written by Xie, Ruili;Xu, Yiping;Ma, Mei;Wang, Zijian. And the article was included in Science of the Total Environment in 2022.Recommanded Product: 101-20-2 This article mentions the following:

Organic contaminants showing aryl hydrocarbon receptor (AhR) agonist activity are commonly detected in areas disturbed by intense human activities and they can initiate a variety of biochem., physiol., and toxicol. effects. A new integrated screening strategy for AhR agonist candidate identification and toxicity confirmation was developed to characterize the AhR-active pollutants in sediments of the contaminated Daqing River basin (DRB) in North China. The specific objectives were to (i) determine the concentrations of known AhR agonists, (ii) identify the novel AhR agonist candidates from nontarget screening (NTS) with structure alerts, computational toxicol. (CompTox) Dashboard bioassays, and in silico predictions, and (iii) evaluate contributions of AhR agonists to the overall potencies and characterize the distribution and source of these pollutants. Significant AhR-mediated potencies were observed in all sediment extracts by in vitro bioassays. Concentrations of polar target chems. in sediment extracts were much lower than nonpolar target chems. A total of 19 known AhR agonists explained 11.3 % to 49.1 % of bioassay-derived AhR-mediated potencies and polychlorinated biphenyls (PCB) 126 and PCB169 were found to contribute significantly to the total effects. 21 compounds screened from NTS by AhR-related structure alerts and further confirmed toxicity by high-throughput bioassays and in silico predictions were selected as AhR agonist candidates. Most of them were substituted PAHs, biphenyls, quinones, substituted phenols and heterocyclic compounds, and they primarily originated from nearby manufacturing industries. Of these compounds, 1-methy-pyrene exhibited significant AhR-mediated potency. Follow up studies should focus on toxicol. mechanism, source, and fate of these novel AhR agonists in water environment.
