Synthesis and antiarrhythmic and parasympatholytic properties of substituted phenols. 2. Amides
摘要:
Thirty amides patterned after the antiarrhythmic drug changrolin were synthesized and their antiarrhythmic and parasympatholytic activities were assessed. There was no correlation between antiarrhythmic and parasympatholytic activities. Several of the amides were found to be potent antiarrhythmic agents that possessed low parasympatholytic activity. All of the compounds appear to act by a class I mechanism.
The humanandrogenreceptor (AR) is considered as a master regulator in the development and progression of prostate cancer (PCa). As resistance to clinically used anti-AR drugs remains a major challenge for the treatment of advanced PCa, there is a pressing need for new anti-AR therapeutic avenues. In this study, we identified a binding site on the DNA binding domain (DBD) of the receptor and utilized

occur between the polar headgroup of the surfactant (OSO3– Na+) and the aza-[18]-crown-6 moiety. DFT calculations confirmed the capability of BG2 to form stable complexes with the Na+ cations, where the cation can be either inside the azacrown cavity or sandwiched between the cavity and the polymer chain, which seem to determine the position of the surfactant hydrocarbon chain and, therefore, be responsible
我们报道了一种新的带有冠醚部分的共轭聚合物的合成,聚[( N (1-aza-[18]crown-6)carbamido)thiophene-2,5-diyl- alt -1,4-phenylene] (BG2 )。在水中,BG2 形成具有轻微混浊外观的分散体。我们研究了添加具有不同极性头基的表面活性剂对这些聚合物-聚合物聚集体的影响。特别注意具有阴离子表面活性剂十二烷基硫酸钠 (SDS) 的体系。光物理技术与电导率、NMR(1 H、13 C 和27Na)、DFT 计算、分子动力学模拟和小角中子散射 (SANS) 提供了关于 SDS/BG2 系统在水溶液和薄膜中的行为的详细图片。NMR、电导率和 DFT 结果表明,表面活性剂的极性头基 (OSO 3 – Na + ) 与 aza-[18]-crown-6 部分之间发生亲水相互作用。DFT 计算证实了 BG2 与 Na +形成稳定络合物的能力阳

Fluorescence “Turn-On” Sensing of Carboxylate Anions with Oligothiophene-Based <i>o-</i>(Carboxamido)trifluoroacetophenones

o-(Carboxamido)trifluoroacetophenones containing ter- or pentathiophene moiety as a fluorophore exhibit fluorescence enhancement upon binding carboxylate anions. Particularly, the terthiophene derivative shows a large fluorescence enhancement factor (FEF = 120). The enhancement is explained by intramolecular H-bonding stabilization of an anion-ionophore adduct, through which a possible quenching process, the n-pi* transition from the trifluoroacetophenone moiety, is eliminated.
