The present invention refers to the field of chemical compounds bearing a 1,2,3-triazole ring of formula (I) and possessing guanidino and carboxylic groups or their isosteres, their preparation by Cu-catalyzed "click-chemistry", and medical - diagnostic use in pathologies where angiogenesis is altered, for example pathologic conditions of tumor origin, tumor metastasis, osteoporosis, and rheumatoid arthritis.

The synthesis of a range of cyclic guanidines via intramolecularringopening of epoxides or iodocyclisation is reported. A preliminary investigation of the glycosidase inhibitory activity of these substances is also discussed.

A novel and efficient synthetic procedure for converting a diverse set of amines to N,N′ -di-Boc-protected guanidines is described. The methodology comprises the use of cyanuricchloride (TCT) as activating reagent for di-Boc-thiourea. The employ of inexpensive TCT instead of classical HgCl 2 eliminates the environmental hazard of heavy-metal waste without appreciable loss of yield or reactivity. This

The cyclisation of N-allyl- and N-homoallylguanidines using DMDO leading to the formation of novel 5- and 6-membered guanidine heterocycles is reported. Several of the products formed displayed weak inhibition of glycosidase enzymes.
