Enhancing fluorescence and lowering the optical gap through CP doping of a π-conjugated molecular backbone: A computational-based design approach

Journal of Photochemistry and Photobiology, 2021
Design principles of organic fluorescent materials are investigated at the molecular level using a first-principles-based computational approach. The design approach incorporates hetero atoms into a conjugated cyclic skeleton by introducing CP bonds. In

Enantioselective Conjugate Allylation of Cyclic Enones [PDF]

The Journal of Organic Chemistry, 2011
Enantioselective organocatalytic 1,2-allylation of a cyclic enone followed by anionic oxy-Cope rearrangement delivered the ketone as a mixture of diastereomers. This appears to be a general method for the net enantioselective conjugate allylation of cyclic enones.

Cyclic conjugation in benzo-annelated triphenylenes [PDF]

Journal of the Serbian Chemical Society, 2010
Cyclic conjugation in benzo-annelated triphenylenes was studied by means of the energy effect (ef) and the π-electron content (EC) of the six-membered rings.

Ultrasound-sensitive cRGD-modified liposomes as a novel drug delivery system

Artificial Cells, Nanomedicine, and Biotechnology, 2022
Targeted liposomes enable the delivery of encapsulated chemotherapeutics to tumours by targeting specific receptors overexpressed on the surfaces of cancer cells; this helps in reducing the systemic side effects associated with the cytotoxic agents. Upon

Modulating Protein–Protein Interactions by Cyclic and Macrocyclic Peptides. Prominent Strategies and Examples

Molecules, 2021
Cyclic and macrocyclic peptides constitute advanced molecules for modulating protein–protein interactions (PPIs). Although still peptide derivatives, they are metabolically more stable than linear counterparts, and should have a lower degree of ...

Effect of benzocyclobutadieno-annelation on cyclic conjugation in fluoranthene congeners [PDF]

Journal of the Serbian Chemical Society, 2011
Earlier studies revealed that benzo-annelation has a peculiar effect on the intensity of cyclic conjugation in the five-membered ring of fluoranthene congeners.

Solid Pseudopapillary Neoplasm of the Pancreas in Children and Adolescents: Expert Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare low‐grade malignant exocrine pancreatic tumor, mostly discovered during the second decade of life in females, with a very good prognosis, provided microscopically complete surgical excision is achieved.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
