  Syntheses of chiral 1,3-disubstituted tetrahydro-β-carbolines via CIAT process: highly stereoselective Pictet–Spengler reaction of d-tryptophan ester hydrochlorides with various aldehydes

  摘要：

  A highly stereoselective Pictet-Spengler reaction of D-tryptophan methyl ester hydrochloride 1-HCl with various aldehydes via a CIAT (crystallization-induced asymmetric transformation) process is described. It was revealed that the CIAT process should be performed in a mixed solvent of nitromethane and toluene, and a fine tuning of the ratio of nitromethane and toluene for each epimer Mixture of 2-HCl was necessary in order to get as high yields and stereoselectivities as possible. Enantiomerically pure cis (or trans) 1,3-disubstituted tetrahydro-beta-carbolines 2a-2v were obtained by recrystallization or flash chromatography after neutralization of the corresponding hydrochloride salts cis-2-HCl or trans-2-HCl.

  In a recent paper, we have described the discovery of antimalarial compounds derived from tadalafil, using a drug-to-genome-to-drug approach (J. Med. Chem. 2011, 54 (9), pp 3222-3240). We have shown that these derivatives inhibit the phosphodiesterase activity of Plasmodium falciparum and the parasite growth in culture. In this paper, we describe the optimization of these compounds. A direct consequence of our approach based on gene orthology is the lack of selectivity of the compounds over the original activity on the human target. We demonstrate here that it is possible to take advantage of subtle differences in SAR between HsPDE5 inhibition and antiplasmodial activity to improve significantly the selectivity. In particular, the replacement of the piperonyl group in compound 2 by a dimethozyphenyl group was the best way to optimize selectivity. This observation is consistent with the differences between human and plasmodial sequences in the Q2 pocket receiving this group.

  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.
