Novel substituted quinazolinones have been found to exhibit specific binding to cholecystokinin (CCK) receptors in the brain and/or peripheral site such as the pancreas and ileum. The quinazolinones are CCK receptor antagonists and find therapeutic application in the treatment of gastrointestinal disorders and central nervous system disorders, and are useful for appetite regulation in mammals. Pharmaceutical formulations for such indications are described.

From an aqueous decoction of the traditional Chinese medicine "ban lan gen" (the Isatis indigotica root), an antiviral natural product CI - 39 was isolated as an NNRTI (non-nucleoside reverse transcriptase inhibitor) (EC50 = 3.40 mu M). Its novel structure was determined as methyl (1-methoxy-1H-indol-3-yl)acetamidobenzoate by spectroscopic data and confirmed by single crystal X-ray diffraction. Through synthesis and structure-activity relationship (SAR) investigation of CI - 39 and 57 new derivatives (24 with EC50 values of 0.06-8.55 mu M), two optimized derivatives 10f and 10i (EC50: 0.06 mu M and 0.06 mu M) having activity comparable to that of NVP (EC50 = 0.03 mu M) were obtained. Further evaluation verified that 10f and 10i were RT DNA polymerase inhibitors and exhibited better activities and drug resistance folds compared to NVP against seven NNRTI-resistant strains carrying different mutations. Especially, 10i (EC50 = 0.43 mu M) was more active to the L100I/K103N double-mutant strain as compared to both NVP (EC50 = 0.76 mu M) and EFV (EC50 = 1.08 mu M). The molecular docking demonstrated a possible binding pattern between 10i and RT and revealed activity mechanism of 10i against the NNRTI-resistant strains. Copyright (C) 2020 Elsevier Masson SAS.
