Investigation Of Synthesis Methods For Novel Pyrrolo[2,3-D]Pyrimidine Derivatives As Kinase Inhibitor Compounds

Abstract

The current study has been planned to synthesize and assess the pharmacological characteristics of pyrrolo[2,3-d]pyrimidine derivatives as kinase inhibitors. The findings of the study indicated that different structural modifications, especially at critical cyclic sites, significantly influenced the development of inhibitory potency and specificity against the target enzymes. Compound 5k was identified as a highly potent multi-target inhibitor with an IC50 value in the nanomolar scale and is capable of inducing apoptosis and facilitating cell cycle arrest in HepG2 cells. These results not only highlight the significance of rational compound design based on efficient chemical structures but also reveal new avenues for the design of anticancer drugs with enhanced efficacy. One of the major accomplishments of this study is the establishment of optimized and effective synthetic procedures for the synthesis of pyrrolopyrimidine derivatives with significant yield and sufficient levels of purity. The application of new reaction conditions and advanced catalytic systems, including microwave-assisted reactions and DBU-catalyzed cyclization, allowed for the circumvention of the drawbacks associated with conventional methodologies. From the pharmacological perspective, the study showed that the pyrrolopyrimidine derivatives synthesized were able to interact effectively with the ATP-binding site of kinase enzymes. Moreover, data about compounds 14a and 17 showed that the derivatives can cause cell cycle arrest at the G1/S phase, which is especially useful for the treatment of cancers that manifest with increased cell growth. The 2-thioalkyl-6-amino-4-oxo pyrimidine compounds were able to engage effectively in a Michael reaction with functionalized nitroalkenes. In addition, the substitution of the thioalkyl group at the C2 position of pyrrolo[3,2-d]pyrimidines was successfully realized.
