The dscovery of the new MCR subsequently also leads to a brand new class of proteprotenteractoantagonsts.Thus, the three part synthess of dversely substtuted and fused amno pyrroloheterocycles by the condensatoof actvated methylene compounds, aldehydes and sontres was lately reported.Ths effcent 3CR prospects to a dversty ofheterocycles a 1 pot fashoand s valuable to the synthess of tens of 1000′s of dscrete compounds.212 By ahgh throughput screenng technique 3 alkyl 2 phenethylndolzne one carbontres had been uncovered to become potent nhbtors within the proteprotenteractobetweevascular endothelal growth issue and neurop1, a method whch s beleved for being nvolved the nvasoof tumour cells ntohumaprostate.The RGD loocontans peptdes which have been the molecular attachment ponts of many cellular and extracellular matrces.Along wth the ntegrns, ther receptors consttute a serious technique for cell adheson,213 whch s crucal several pathologcal processes, such as tumour metastass, angogeness, osteopoross, and thromboss.
