2,4-Diaminothienopyrimidines as Orally Active Antimalarial Agents
摘要:
A novel series of 2,4-diaminothienopyrimidines with potential as antimalarials was identified from whole-cell high-throughput screening of a SoftFocus ion channel library. Synthesis and structure activity relationship studies identified compounds with potent antiplasmodial activity and low in vitro cytotoxicity. Several of these analogues exhibited in vivo activity in the Plasmodium berghei mouse model when administered orally. However, inhibition of the hERG potassium channel was identified as a liability for this series.

Based on the initial optimization of orally active antimalarial 2,4-diamino-thienopyrimidines and with the help of metabolite identification studies, a second generation of derivatives involving changes at the 2- and 4-positions of the thienopyrimidine core were synthesized. Improvements in the physiochemical properties resulted in the identification of 15a, 17a, 32, and 40 as lead molecules with improved
our previously discovered long‐acting compounds with pyrrolopyrimidine scaffold. With the aid of an in silicobiotransformationpredictiontool, (R)‐2‐((2‐(3‐aminopiperidin‐1‐yl)‐4‐oxo‐6‐(pyridin‐3‐yl)thieno[3,2‐d]pyrimidin‐3(4H)‐yl)methyl)‐4‐fluorobenzonitrile was eventually generated and determined to have high potency, a fine pharmacokinetic profile, and a long‐acting in vivo efficacy.
