The contemporary work depicts synthesizing an innovative sequence of polyfunctionalized Pyrazolo[34-b]pyridine congeners ES1-ES18 and assessed for antimicrobial antitumor telomerase inhibition and Anti-hepatitis B efficacies applying an array of techniques. Fortunately most of the compounds demonstrated auspicious bio efficiencies. Additionally in silico simulation was executed for determining the synthetic Pyrazolo[34-b]pyridines anticipated mode of action. Compounds ES4 ES5 and ES6 were picked as the most potent and efficient candidates versus the telomerase enzyme [PDB id: 2B2A]. The consequences exposed that compound ES5 is the extremely credible operative in contradiction of telomerase enzyme as it disclosed the best binding score and interaction pose. These initial outcomes may improve in introducing more research strategies converged on pyrazolo[34-b]pyridines exclusively those with anticipated bioefficacy ultimate ADMET parameters and constructive prospects.
