Synthesis of Purine and 2-Aminopurine Conjugates with N-(4-Aminobenzoyl)-(S)-glutamic Acid
摘要:
Purine and 2-aminopurine conjugates with N-(4-aminobenzoyl)-(S)-glutamic acid connected to C-6 of the purine system either directly or through an aminoethyl linker have been synthesized by nucleophilic substitution of chlorine in 6-chloropurine and 2-amino-6-chloropurine. 2-Aminopurine conjugate with 4-aminobenzoic acid linked through a glycine residue has also been obtained. Testing of the synthesized compounds for tuberculostatic activity in vitro has revealed a moderate activity of methyl 4-[2-(2-aminopurin-6-ylamino)-acetyl]amino}benzoate.

Many GTPases such as Ras, Ral and Rho require post-translational farnestylation or geranylgeranylation for mediating malignant transformation. Dual farnesyltransferase (FT) (FTI) and geranylgeranyltransferase-I (GGT-1) inhibitors (GGTI) were developed as anticancer agents from based on an ethylenediamine scaffold. On the basis of a 4-fold substituted ethylenediamine scaffold, the inhibitors are structurally simple and readily derivatized, facilitating extensive structure-activity relationship studies. The most potent inhibitor is compound exhibited an in vitro hFTase IC50 value of 25 nM and a whole cell H-Ras processing IC50 value of 90 nM. Several of the inhibitors proved highly selective for hFTase over the related prenyltransferase enzyme geranylgeranyltransferase-I (GGTase-I). A crystal structure of an inhibitor cocrystallized with farnesyl pyrophosphate in the active site of rat FTase illustrates that the para-benzonitrile moiety is stabilized by a π-π stacking interaction with the Y361β residue, suggesting an importance of this component of the inhibitors.
