Synthetic Route of C5H2Cl2N4. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 2,6-Dichloropurine, is researched, Molecular C5H2Cl2N4, CAS is 5451-40-1, about Structure-Based Optimization of Quinazolines as Cruzain and TbrCATL Inhibitors. Author is Barbosa da Silva, Elany; Rocha, Debora A.; Fortes, Isadora S.; Yang, Wenqian; Monti, Ludovica; Siqueira-Neto, Jair L.; Caffrey, Conor R.; McKerrow, James; Andrade, Saulo F.; Ferreira, Rafaela S..
The cysteine proteases, cruzain and TbrCATL (rhodesain), are therapeutic targets for Chagas disease and Human African Trypanosomiasis, resp. Among the known inhibitors for these proteases, N4-benzyl-N2-phenylquinazoline-2,4-diamine (1a I [R1 = phenyl; R2 = benzyl] in this study), as a competitive cruzain inhibitor (Ki = 1.4μM) was described. The synthesis and biol. evaluation of 22 analogs I [R1 = Ph, 4-OH-Ph, 2-pyridyl; R2 = benzyl, Ph, 3-Cl-Ph, etc] of I [R1 = phenyl; R2 = benzyl], containing modifications in the quinazoline core, and in the substituents in positions 2 and 4 of this ring was described. The analogs I demonstrate low micromolar inhibition of the target proteases and cidal activity against Trypanosoma cruzi with up to two log selectivity indexes in counterscreens with myoblasts. Fourteen compounds were active against Trypanosoma brucei at low to mid micromolar concentrations During the optimization of I [R1 = phenyl; R2 = benzyl], structure-based design and prediction of physicochem. properties were employed to maintain potency against the enzymes while removing colloidal aggregator characteristics observed for some mols. in this series.
