On the basis of our earlier molecular docking analysis, we designed and synthesized 5-((arylfuran/1H-pyrrol-2-yl)methylene)-2-thioxo-3-(3-(trifluoromethyl)phenyl)thiazolidin-4-ones (12a-o) as HIV-1 entry inhibitors. Compounds 12a-o effectively inhibited infection by both laboratory-adapted and
The Eph receptor tyrosine kinases regulate a variety of physiological and pathological processes not only during development but also in adult organs, and therefore they represent a promising class of drug targets. The EphA4 receptor plays important roles in the inhibition of the regeneration of
In Hb Warsaw Val replaces the Phe normally present at the heme contact position beta 42 (CD1). This variant is unstable, and it readily undergoes methemoglobin formation. In DEAE-cellulose chromatography, the variant hemoglobin co-eluted with Hb A; a partially heme-depleted fraction of the variant,
Expanded porphyrins are attractive research targets because of their large and flexible structures, optical and electrochemical properties, and diverse coordination abilities. We are interested in the use of double bonds within expanded porphyrins because double bonds could conduct isomerization,
This Letter details a simple and effective method to synthesize a porphyrin(2.1.2.1)-based nanobelt NBNi3 via condensation reactions of 1,2,4,5-tetra(pyrrol-2-yl)benzene and benzaldehydes. NBNi3 consists of three arch-shaped porphyrins(2.1.2.1) and benzene linkages with a
In an effort to develop potent monoamine oxidase (MAO) inhibitors, new pyrrole derivatives were obtained via the selective reduction of the CC bonds of 1-(1-methyl-1H-pyrrol-2-yl)-3-[5-(aryl)furan-2-yl]prop-2-en-1-ones through palladium catalyzed hydrogenation in ethanol. The synthesized compounds
Two novel calix[n]arene-adorned gold electrodes producing high photocurrent intensities were successfully constructed by embedding gold electrode surfaces with both P(4-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)benzenamine) conducting polymer and 4-mercaptoboronic acid-functionalized semiconductor CdS
In mammalian peroxidases the proximal histidine is in close interaction with a fully conserved asparagine which in turn is hydrogen bonded with an arginine that stabilizes the propionate substituent of pyrrol ring D in bent conformation. In order to probe the role of this rigid proximal architecture
NMDA receptors are tetrameric complexes of GluN1, GluN2A-D, and GluN3A-B subunits and are involved in normal brain function and neurologic disorders. We identified a novel class of stereoselective pyrrolidinone (PYD) positive allosteric modulators for GluN2C-containing NMDA receptors, exemplified by
Polypyrrole is one of the most investigated conductive polymers used for tissue engineering applications because of its advantageous properties and the ability to promote different cell types' adhesion and proliferation. Together with β-cyclodextrin, which is capable of accommodating helpful
