PYRROLO[2,3-B]PYRIDIN DERIVATIVES AS INHIBITORS OF INFLUENZA VIRUS REPLICATION

Provided herein are compounds of Formula A, B or C that can inhibit the replication of influenza viruses, reduce the amount of influenza viruses, and/or treat influenza.

PYRROLOPYRIMIDINE DERIVATIVES USEFUL AS INHIBITORS OF INFLUENZA VIRUS REPLICATION

Methods of inhibiting the replication of influenza viruses in a biological sample or patient, of reducing the amount of influenza viruses in a biological sample or patient, and of treating influenza in a patient, comprises administering to said biological sample or patient a safe and effective amount of a compound represented by any of Formulas l-lll, or a pharmaceutically acceptable salt thereof. A pharmaceutical composition comprises a safe and effective amount of such a compound or pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable carrier, adjuvant or vehicle.

Combinatorial synthesis of PEG oligomer libraries

A simple chain-extending approach was established for the scale-up of the monoprotected monodisperse PEG diol materials. Reactions of THP-(OCH2CH2)n—OMs (n=4, 8, 12) with a large excess of commercially available H—(OCH2CH2)n—OH (n=1-4) under basic conditions led to THP-(OCH2CH2)n—OH (n=5-15). Similarly, Me-(OCH2CH2)n—OH (n=4-11, 13) were prepared from Me-(OCH2CH2)n—OMs (n=3, 7, 11). For the chain elongation steps, 40-80% yields were achieved through extraction purification. PEG oligomer libraries I and II were generated in 50-95% overall yields by alkylation or acylation of THP-(OCH2CH2)n—OH (n=1-15) followed by deprotection. Alkylation of Me-(OCH2CH2)n—OH (n=1-11, 13) with X—(CH2)m—CO2R (X=Br or OMs) and subsequent hydrolysis led to PEG oligomer library III in 30-60% overall yields. Combinatorial purification techniques were adapted to the larger-scale library synthesis. A total of 498 compounds, each with a weight of 2-5 g and a minimum purity of 90%, were synthesized.
