Synthesis and Activity of Biomimetic Biofilm Disruptors [PDF]

, 2013
Biofilms are often associated with human bacterial infections, and the natural tolerance of biofilms to antibiotics challenges treatment. Compounds with antibiofilm activity could become useful adjuncts to antibiotic therapy.

Derivatives of the triaminoguanidinium ion, 5. Acylation of triaminoguanidines leading to symmetrical tris(acylamino)guanidines and mesoionic 1,2,4-triazolium-3-aminides

Beilstein Journal of Organic Chemistry, 2017
Depending on the reaction conditions, N,N’,N’’-tris(benzylamino)guanidinium salts can react with carboxylic acid chlorides to form either symmetrical N,N’,N’’-tris(N-acyl-N-benzylamido)guanidines 6 or mesoionic 4-amino-1,2,4-triazolium-3-hydrazinides 7 ...

Development of a Promising Method for Producing Oligomeric Mixture of Branched Alkylene Guanidines to Improve Substance Quality and Evaluate Their Antiviral Activity against SARS-CoV-2

Molecules, 2021
This paper reports the synthesis of branched alkylene guanidines using microfluidic technologies. We describe the preparation of guanidine derivatives at lower temperatures, and with significantly less time than that required in the previously applicable

Interatomic Distances in Covalent Molecules and Resonance between Two or More Lewis Electronic Structures [PDF]

, 1932
In a paper to be published in the Zeitschrift für Kristallographie, Professor M. L. Huggins and I have formulated tables of radii for use in crystals containing electron-pair bonds. With the aid of these tables, we have also constructed a table of radii (

Nitrophenylsulfonyguaniden en hun splitsing door alkaliën [PDF]

, 1947
For preparing sulphaguanidine the reaction of p-nitrobenzenesulphochloride with guanidine in alcaline medium was examined. The controversy 1) which has arisen on the subject of this reaction has been proved to rest on incomplete examination.

Design and synthesis of a photoswitchable guanidine catalyst

Beilstein Journal of Organic Chemistry, 2012
A novel design as well as a straight-forward synthesis for a photoswitchable guanidine catalyst is reported. Intense studies of the photochromic properties demonstrated the reversible switchability of its photosensitive azobenzene moiety. Its activity in

X-ray Structure of Eleven New N,N′-Substituted Guanidines: Effect of Substituents on Tautomer Structure in the Solid State

Crystals
Guanidine-containing molecules are an interesting class of compounds within both medicinal and material sciences. Having knowledge of their tautomerism is key in designing guanidines that interact with biological and chemical receptors.
