Gensini, Martina; Altamura, Maria; Dimoulas, Tula; Fedi, Valentina; Giannotti, Danilo; Giuliani, Sandro; Guidi, Antonio; Harmat, Nicholas J. S.; Meini, Stefania; Nannicini, Rossano; Pasqui, Franco; Tramontana, Manuela; Triolo, Antonio; Maggi, Carlo Alberto published the artcile< Modulation on C- and N-Terminal Moieties of a Series of Potent and Selective Linear Tachykinin NK2 Receptor Antagonists>, Name: 4-Chloro-2-methoxybenzaldehyde, the main research area is tachykinin NK2 receptor antagonist preparation structure activity.

Herein we describe the synthesis of a series of new potent tachykinin NK2 receptor antagonists by the modulation of the C- and N-terminal moieties of ibodutant (MEN 15596, 1). The N-terminal benzo[b]thiophene ring was replaced by different substituted naphthalenes and benzofurans, while further modifications were evaluated at the C-terminal tetrahydropyran moiety. Most compounds demonstrated a high affinity for the human NK2 receptor and high in vitro antagonist potency, indicating that a wide range of substituents at both termini can be incorporated in the mol. without detrimental effects on the interactions with the NK2 receptor. Selected compounds were tested in vivo confirming their activity as NK2 antagonists. In particular, after both iv and id administration to guinea pig, compound 61 b was able to antagonize NK2-induced colonic contractions with a potency and duration-of-action fully comparable to the reference compound 1 (MEN 15596, ibodutant).

Hoffmann, Maxi’s team published research in Polymers (Basel, Switzerland) in 2022 | 1592-20-7

Polymers (Basel, Switzerland) published new progress about Dielectric constant. 1592-20-7 belongs to class chlorides-buliding-blocks, and the molecular formula is C9H9Cl, Recommanded Product: 1-(Chloromethyl)-4-vinylbenzene.

Hoffmann, Maxi; Iacob, Ciprian; Kaysan, Gina; Simmler, Mira; Nirschl, Hermann; Guthausen, Gisela; Wilhelm, Manfred published the artcile< Charge Transport and Glassy Dynamics in Blends Based on 1-Butyl-3-vinylbenzylimidazolium Bis(trifluoromethanesulfonyl)imide Ionic Liquid and the Corresponding Polymer>, Recommanded Product: 1-(Chloromethyl)-4-vinylbenzene, the main research area is butyl vinylbenzylimidazolium bistrifluoromethanesulfonyl imide ionic liquid polymer glassy dynamic; PFG-NMR; broadband dielectric spectroscopy; charge transport; imidazolium; ionic liquid blends; ionic liquids; rheology.

Charge transport, diffusion properties, and glassy dynamics of blends of imidazolium-based ionic liquid (IL) and the corresponding polymer (polyIL) were examined by Pulsed-Field-Gradient NMR (PFG-NMR) and rheol. coupled with broadband dielec. spectroscopy (rheo-BDS). We found that the mech. storage modulus (G’) increases with an increasing amount of polyIL and G’ is a factor of 10,000 higher for the polyIL compared to the monomer (GIL’ = 7.5 Pa at 100 rad s-1 and 298 K). Furthermore, the ionic conductivity (σ0) of the IL is a factor 1000 higher than its value for the polymerized monomer with 3.4×10-4 S cm-1 at 298 K. Addnl., we found the Haven Ratio (HR) obtained through PFG-NMR and BDS measurements to be constant around a value of 1.4 for the IL and blends with 30 weight% and 70 weight% polyIL. These results show that blending of the components does not have a strong impact on the charge transport compared to the charge transport in the pure IL at room temperature, but blending results in substantial modifications of the mech. properties. Furthermore, it is highlighted that the increase in σ0 might be attributed to the addition of a more mobile phase, which also possibly reduces ion-ion correlations in the polyIL.

Prothioconazole is a fungicide that has a wide number of applications in agriculture, and it can ensure the safety of crops, users, and the environment. Prothioconazole, as a suppressor of copper dissolution in 0.5 M H2SO4 solution, has been evaluated using electrochem. experiments, weight loss tests, quantum chem. calculations, and SEM (SEM). The electrochem. test results showed that prothioconazole was an excellent inhibitor, and the anticorrosion ability increased with the inhibitor concentration The interaction of prothioconazole with copper is a spontaneous adsorption process accompanied by typical chemisorption. The number of water mols. (X) displaced by one prothioconazole mol. was obtained using diverse substitutional adsorption models based on electrochem. impedance spectroscopy (EIS) data. In addition, the Fukui functions indicate that the triazole and benzene rings and the -C=S atoms were the main active sites for the adsorption process.

MacLeod, Angus M.’s team published research in Journal of Medicinal Chemistry in 1990 | CAS: 38362-15-1

5-Chloro-1,2,4-thiadiazole(cas: 38362-15-1) is a member of organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. They are generally not present in crude oils and are typically the result of additives, cleaning solutions or chemicals used for oil recovery.Application of 38362-15-1

MacLeod, Angus M.; Baker, Raymond; Freedman, Stephen B.; Patel, Shailendra; Merchant, Kevin J.; Roe, Michael; Saunders, John published an article in Journal of Medicinal Chemistry. The title of the article was 《Synthesis and muscarinic activities of 1,2,4-thiadiazoles》.Application of 38362-15-1 The author mentioned the following in the article:

A series of novel 1,2,4-thiadiazoles bearing a mono- or bicyclic amine at C-5 were prepared Quinuclidine and 1-azabicyclo[2.2.1]heptane derivatives e.g., I (R = H, Me, Et, Me2CH, cyclopropyl, CH2Ph, OMe; n = 1, 2) were synthesized by reaction of the lithium enolate of the 3-methoxycarbonyl compounds followed by ester hydrolysis and decarboxylation. The receptor binding affinity and efficacy of these compounds as muscarinic ligands was assessed by radioligand binding assays using [3H]-N-methylscopolamine and [3H]oxotremorine-M. Optimal agonist affinity was observed for 3′-Me compounds Smaller substituents (H) retained efficacy with reduced affinity while larger groups led to substantially lower efficacy. The observed binding affinity was influenced both by the conformational energy of rotation around the C(3)-C(5′) bond and the steric requirement of the mono- or bicyclic amine. In the experimental materials used by the author, we found 5-Chloro-1,2,4-thiadiazole(cas: 38362-15-1Application of 38362-15-1)
