Investigations regarding the utility of prodigiosenes to treat leukemia
(2013)
Prodigiosenes, possessing a 4-methoxypyrrolyldipyrrin skeleton, are known for their anti-cancer
activity. Structural modification of the C-ring resulted in a series of prodigiosenes that displayed
promising activity against ...
Synthesis and characterisation of the unsubstituted dipyrrin and 4,4-dichloro-4-bora-3a,4a-diaza-s-indacene: improved synthesis and functionalisation of the simplest BODIPY framework
(2013)
An improved and scalable synthesis of the unsubstituted
4,4-difluoro-4-bora-3a,4a-diaza-s-indacene framework facilitates access to the previously unreported
parent dipyrrin HCl salt, as well as 4,4-dichloro-4-bora-3a,4a- ...
Conversion of F-BODIPYs to Cl-BODIPYs: Enhancing the Reactivity of F-BODIPYs
(2013-01)
A new method for the synthesis of Cl-BODIPYs from F-BODIPYs is reported, merely requiring
treatment of the F-BODIPY with boron trichloride. Cl-BODIPYs are exploited as synthetic
intermediates generated in situ for the ...
Synthesis and biological evaluation of prodigiosene conjugates of porphyrin, estrone and 4-hydroxytamoxifen
(Bioorganic & Medicinal Chemistry, 2013)
To generate the first series of prodigiosene conjugates, the tripyrrolic skeleton was appended to estrone, tamoxifen and porphyrin frameworks by way of ester linkers and various hydrocarbon chain lengths. The ability of ...
Microwave-assisted reduction of F-BODIPYs and dipyrrins to generate dipyrromethanes
(Canadian Journal of Chemistry, 2013)
The reduction of BODIPYs and dipyrrins to dipyrromethanes, via a reaction involving ethylene glycol and sodium methoxide, is reported. When benzyl alcohol is used in place of ethylene glycol, the addition of 2,4-dinitrop ...
Antimicrobial Activity of Non-natural Prodigiosenes
(RSC Advances, 2013)
Tripyrrolic prodigiosenes, derivatives of the natural product prodigiosin, have been produced via multi-step synthesis beginning with 2-formyl pyrroles bearing various functionalities at the 4-position. Two tin complexes ...
