A series of symmetrically substituted diphenylacetylene derivatives possessing electron-donating or electron-accepting character were prepared and studied with respect to their spectral photophysical properties.
The influence of the stable 2,2,6,6-tetramethylpiperidinyl-N-oxyl (TEMPO) nitroxide and its six C4-substituted derivatives, as well two C3-substituted analogues 2,2,5,5-tetramethylpyrrolidynyl-N-oxyl (PROXYL) on chosen fluoroquinolone antibiotics (marbofloxacin, ciprofloxacin, danofloxacin, norfloxacin, enrofloxacin, levofloxacin ofloxacin), has been examined in aqueous solutions by UV absorption steady-state time-resolved fluorescence spectroscopies. mechanism quenching specified proved to...
Pancreatic cancer is one of the leading causes death in Western societies. Its late diagnosis and resistance to chemotherapies result a high mortality rate; thus, development more effective therapies for treatment pancreatic strongly warranted. Usnic acid (UA) secondary metabolite lichens that shows modest antiproliferative activity toward cells. Recently, we reported synthesis UA pyrazole derivative, named 5, which was active than parent compound cervical Here, its anticancer potential has...
Pull–push molecules containing dimethylaniline and aromatic hydrocarbon linked by an acetylene unit were studied using spectroscopic methods DFT theoretical calculations.
Nucleopeptides (NPs) represent synthetic polymers created by attaching nucleobases to the side chains of amino acid residues within peptides. These compounds amalgamate characteristics peptides and nucleic acids, showcasing a unique ability recognize RNA structures. In this study, we present design synthesis Fmoc-protected nucleobase acids (1,4-TzlNBAs) new class NPs, where canonical are affixed chain L-homoalanine (Hal) through 1,4-linked-1,2,3-triazole (HalTzl). 1,4-TzlNBAs suitable for...
Antifungal polyene macrolide antibiotics Amphotericin B (AmB) and Nystatin (NYS) were conjugated through the ω-amino acid linkers with diwalled "molecular umbrellas" composed of spermidine-linked deoxycholic or cholic acids. The presence "umbrella" substituents modulated biological properties antibiotics, especially their selective toxicity. Some AmB-umbrella conjugates demonstrated antifungal in vitro activity comparable to that mother antibiotic but diminished mammalian toxicity, hemolytic...
The spectral and photophysical properties of newly synthesized 3,6-di-<italic>tert</italic>-butyl-8<italic>H</italic>-indolo[3,2,1-de]acridin-8-one were studied.
High hopes have been placed on the organic emitters, which are supposed to solve problem of low stability blue OLEDs. The phenomenon thermally activated delayed fluorescence (TADF),...
Abstract The photophysical properties of the newly synthesized unsymmetrically substituted aromatic acetylene derivative 9‐(2‐(4‐( N,N ‐dimethylamino)phenyl)ethynyl)anthracene‐10‐carbonitrile (CNAacDMA) were investigated with steady‐state and time‐resolved fluorometry. In saturated hydrocarbon solvents, only fluorescence from a locally‐excited state (LE) is recorded. more polar solvents however, excitation this dye leads to charge transfer (CT). moderate (ϵ=4–8) dual emission observed as...
The photophysical behavior of 9-(2-(4-(N,N-dimethylamino)phenyl)ethynyl)anthracene-10-carbonitrile (CNAacDMA) was investigated with absorption and steady-state fluorometry. Studies have shown extremely interesting properties the analyzed derivative. studied molecule is characterized by dual fluorescence bidirectional fluorescence. These two observed phenomena are interrelated. Dual analysis (part 1) explains compound in polar solvents shows only one emission band, however moderate emission....
There are two mol-ecules in the asymmetric unit of title compound, C(19)H(16)O. Neighbouring linked through O-H⋯O hydrogen bonds into an R(4) (4)(8) ring motif. also C-H⋯π and π-π inter-actions. The either parallel to each other or inclined at angle 12.5 (1)°.
