Design, synthesis and biological activity of β-carboline-based type-5 phosphodiesterase inhibitors
摘要:
The SAR of a series of beta-carboline derived type 5 phosphodiesterase inhibitors has been explored and we have discovered compounds with excellent levels of PDE5 potency and selectivity over PDE6. However, the series exhibits low levels of selectivity over PDE11, a phosphodiesterase with unknown function. (C) 2003 Elsevier Science Ltd. All rights reserved.
Syntheses of new substituted triazino tetrahydroisoquinolines and β-carbolines as novel antileishmanial agents1
摘要:
A series of triazino tetrahydroisoquinolines (3-5) and beta-carboline derivatives (15-27) have been synthesized as novel antileishmanial agents. Among them, compounds 15, 16 and 25 have shown 78.0%, 78.6% and 68.0% in vivo inhibition against Leishmania donovani at a dose of 50 mg kg(-1) x 5 days, respectively, while compounds 3 and 18 exhibited 55.6% and 53.3% in vivo inhibitions, respectively, against L. donovani at a dose of 50 mg kg(-1) x 5 days.

homology model of CCK-2R using human A2a adenosine receptor and the resolved NMR based structure of the third extracellular loop of the CCK-2R as templates. Further in order to identify novel antiulcer agents, rational designing have been performed utilizing the substructure of a well-known CCK-2R antagonist benzotript as a lead molecule and submitted to the combined docking and simulation studies.

A series of tetrahydro-beta-carbolines and 1,3,5-triazine hybrids have been synthesized and evaluated for their cytotoxicity against a panel of eight human cancer cell lines and normal human fibroblasts (NIH3T3). It led us to discovery of racemic compounds 69, 71 and 75, which are selectively cytotoxic towards KB (oral cancer) cell line with IC(50) values of 1058, 664 7 and 122.2 nM, respectively, while their enantiopure forms are less active and not selective. Enantiopure compound 42 showed 2 5 times more selectivity towards MCF7 cells over normal fibroblast NIH3T3 cells with an IC(50) value of 740 nM, also arrests cell cycle in G(1) phase and induces apoptosis in MCF7 and MDA MB231cell lines.
