Inhibition of Adamalysin II and MMPs by Phosphonate Analogues of Snake Venom Peptides
摘要:
Phosphonate analogues of the peptidomimetic N-(Furan-2-yl)carbonyl-Leu-Trp-OH were prepared with the goal of evaluating the effect of phosphonate for carboxylate replacement on binding with snake venom metalloproteinases and MMPs, N(Furan-2-yl)carbonyl-Leu-L-Trp(P)-(OH)(2) showed a 75-fold increase of the inhibiting activity against adamalysin II, a snake venom metalloproteinase structurally related to MMPs and TACE. Both the phosphonate and carboxylate peptidomimetics fit into the active site adopting a retrobinding mode and provide the structural base for a new class of metalloproteinases inhibitors.

Objects of the present invention are compounds of a peptido-mimetic character having the capacity of acting as inhibitors of metalloproteinases produced by venom of snake, and of other metalloproteinases of human origin which have been put in relation with various pathologies in man, including tumoral growth and metastatization, aterosclerosis, multiple sclerosis, Alzheimer's disease, osteoporosis, hypertension, rheumatoid arthritis and other inflammatory diseases.
Object of the present invention is also the procedure for the production of diethylester of (1)-phosphotryptophan, as an initial product necessary to synthesize all compounds mentioned above.

agents of D2R suitable for the treatment of CNS-related diseases. Additionally, the pharmacological and biological data herein reported, along with >20 000 outcomes of preclinical assays, was used to seek a general model to predict the allosteric modulatory potential of molecular candidates for a myriad of target receptors, organisms, cell lines, and biological activity parameters based on perturbation

examined for the synthesis of 2-oxazolines via intramolecular cyclodemesylation. To determine the solvent effect, aprotic/protic polar and nonpolar solvents were screened and polar protic solvents met the best result. The remarkable feature of this synthesis is that cyclization takes place in the absence of any base or reagent, in high yields (89–96%). As a result, a series of 4-substituted chiral 2-oxazolines
