Phosphatidylcholine-specific phospholipase C (PC-PLC) is a promising target for new anticancer treatment. Herein, we report our work in the discovery of novel drug-like PC-PLC inhibitors. Virtual screening led to the identification of promising hits from four different structural series that contain the molecular scaffold of benzenesulphonamides (10), pyrido[3,4-b]indoles (22), morpholinobenzoic acid (84) and benzamidobenzoic acid (80). 164 structural analogues were tested to investigate the chemical space around the hit series and to generate preliminary structurally activity relationships (SAR). Two of the pyrido[3,4-b]indoles (22_10 and 22_15) had comparable or better potency as D609, an established but non-drug-like PC-PLC inhibitor. Furthermore, three morpholinobenzoic acids (84, 84_4 and 84_5) had superior potency than D609. Therefore, this study paves the way towards the development of drug-like PL-PLC inhibitors as potential anticancer agents. (C) 2019 Elsevier Masson SAS. All rights reserved.

Techniques for the identification of the protein target(s) of small molecules are proving very important following an increase in the use of phenotype-based screening in chemical biology and drug discovery. One approach, known as the yeast-3-hybrid approach, has shown considerable potential. A key factor in the success of this approach is the preparation of a complex molecule referred to as a chemical inducer of dimerisation (CID). The synthesis of two CIDs based on a bioactive tetrahydro-β-carboline core structure is reported and evidence presented that shows the CIDs are of utility in this approach. A series of chemo- and bioinformatic studies coupled with SAR development inspired the choice of CIDs.
