Drug efflux pumps confer multidrug resistance to dangerous bacterial pathogens which makes these proteins promising drug targets. Herein, we present initial chemical optimization and structure-activity relationship (SAR) data around a previously described efflux pump inhibitor, nordihydroguaretic acid (NDGA). Four series of novel NDGA analogues that target Escherichia coli AcrB were designed, synthesized and evaluated for their ability to potentiate the activity of antibiotics, to inhibit AcrB-mediated substrate efflux and reduce off-target activity. Nine novel structures were identified that increased the efficacy of a panel of antibiotics, inhibited drug efflux and reduced permeabilization of the bacterial outer and inner membranes. Among them, WA7, WB11 and WD6 possessing broad-spectrum antimicrobial sensitization activity were identified as NDGA analogues with favorable properties as potential AcrB inhibitors, demonstrating moderate improvement in potency as compared to NDGA. In particular, WD6 was the most broadly active analogue improving the activity of all four classes of antibacterials tested.
Mo-Based Oxidizers as Powerful Tools for the Synthesis of Thia- and Selenaheterocycles
Franzmann, Peter,Beil, Sebastian B.,Schollmeyer, Dieter,Waldvogel, Siegfried R.
supporting information, p. 1936 - 1940 (2019/01/14)
A highly efficient synthetic protocol for the synthesis of thia- and selenaheterocycles has been developed. By employing a MoCl5-mediated intramolecular dehydrogenative coupling reaction, a broad variety of structural motifs was isolated in yields up to 94 %. The electrophilic key transformation is tolerated by several labile moieties like halides and tertiary alkyl groups. Due to the use of disulfide or diselenide precursors, a high atom efficiency was achieved.

Dopamine, perhaps the simplest molecule that covalently links catechol and amine, together with its derivatives, has shown impressive adhesive and coating properties with its polymers. However, the scope of the molecules is rather limited, and the polymer

A novel and efficient synthesis of dihydrexidine
Cueva, Juan Pablo,Nichols, David E.
experimental part, p. 715 - 720 (2009/09/06)
An efficient synthesis of the dopamine D1 selective full agonist dihydrexidine has been achieved in high yields and requiring no chromatographic separations via a facilitated intramolecular Henry cyclization of a (nitropropyl)benzophenone and subsequent diastereomerically selective reduction of the resulting tricyclic ni- troalkene.
