Synthetic Studies towards Darobactin A

Chemistry – A European Journal, EarlyView.
The urgent need for new antibiotics led us to develop a new methodology for the synthesis of the natural product darobactin A selectively targeting gram‐negative bacteria. This study provides new insights into the synthesis of strained indole‐containing macrocycles.

Dual‐State Photophysical Modulation via Bifurcated Hydrogen Bonding in a U‐Shaped Dipyridophenazine‐Cored Donor‐π‐Acceptor‐π‐Donor Fluorophore

Chemistry – A European Journal, EarlyView.
A donor–π–acceptor–π–donor (D–π–A–π–D) fluorophore bearing a U‐shaped dipyridophenazine core forms bifurcated hydrogen bonds with neutral donors such as sulfonamides or water. This interaction modulates both ground and excited states, enabling red‐shifted emission and enhanced photoluminescence in solution and solid state.

Synthesis of pyrimidines, aromatic and heteroaromatic acids as Biginelli reaction catalysts [PDF]

, 2015
Aromatic as well as heteroaromatic acids were found to beexcellent catalysts for the Biginelli three component synthesisof dihydropyrimidinones. Benzoic acid, substituted benzoic acids, five- and six- membered heterocyclic acids can be used for this ...

Chemo‐Enzymatic Route for Covalent Cellulose Fiber Dyeing

Chemistry – A European Journal, EarlyView.
This work presents a proof of concept for a chemo‐enzymatic approach to the covalent dyeing of cotton fibers. Laccase/TEMPO oxidation introduces aldehyde groups, enabling subsequent reductive amination with amino dyes. Excellent color homogeneity and wash fastness were demonstrated using acid red 33, highlighting the robustness of the approach and its ...

Fire-resistant phosphorus containing polyimides and copolyimides [PDF]

, 1985
Phosphorus-containing polyimides and copolyimides are synthesized in a two-step polycondensation reaction from 1- (diorganooxyphosphonl)methly 2,4- and 2,6-diaminobenzenes and tetracarboxylic anhydride. The diorgano position of the diorganooxyphosphonyl

Design, Synthesis and biological evaluation of novel acridine-polyamine conjugates against prostate cancer [PDF]

, 2009
Prostate cancer is the most common cause of cancer death in men, aged 85 and over. Androgen receptor, a single polypeptide with three functional domains is very important during initiation and progression of the disease.
