Based on overlapping structural requirements for both efficient aldose reductase inhibitors and PPAR ligands, [5-(benzyloxy)-1H-indol-1-yl] acetic acid (compound 1) was assessed for inhibition of aldose reductase and ability to interfere with PPAR gamma. Aldose reductase inhibition by 1 was characterized by IC50 in submicromolar and low micromolar range, for rat and human enzyme, respectively. Selectivity in relation to the closely related rat kidney aldehyde reductase was characterized by approx. factor 50. At organ level in isolated rat lenses, compound 1 significantly inhibited accumulation of sorbitol in a concentration-dependent manner. To identify crucial interactions within the enzyme binding site, molecular docking simulations were performed. Based on luciferase reporter assays, compound 1 was found to act as a ligand for PPAR gamma, yet with rather low activity. On balance, compound 1 is suggested as a promising lead-like scaffold for agents with the potential to interfere with multiple targets in diabetes.


The b -> sgg decay in the two and three Higgs doublet models with CP violating effects
Goksu, A; Iltan, EO; Solmaz, L (2001-04-20)
We study the decay width and CP asymmetry of the inclusive process b --> sgg (g denotes gluon) in the three and two Higgs doublet models with complex Yukawa couplings. We analyze the dependencies of the differential decay width and CP asymmetry to the s-quark energy E-s and CP violating parameter theta. We observe that there exist a considerable enhancement in the decay width and CP asymmetry is at the order of 10(-2). Further, it is possible to predict the sign of C-7(eff) using the CP asymmetry.
The Chemistry of Ethyl 3-(2-Ethoxy-2-oxoethyl)-1H-indole-2-carboxylate: Synthesis of Pyrimido[4,5-b]indoles and Diethyl 4-Hydroxyquinoline-2,3-dicarboxylate via Intramolecular Cyclizations
KAPTI, Tolga; Dengiz, Çağatay; BALCI, METİN (2017-04-01)
We report the synthesis of a new series of 2-oxo-1,2,4,9-tetrahydro- 3H-pyrimido[4,5-b] indole derivatives and diethyl 4-hydroxyquinoline- 2,3-dicarboxylate starting from ethyl 3-(2-ethoxy-2-oxoethyl)- 1H-indole-2-carboxylate. Intramolecular cyclization formed the target ring systems. The key substrates featuring both acyl azide and isocyanate functionalities were prepared from bis(acyl azide) intermediate. The acyl azide functionalities directly connected to methylene groups were regiospecifically converte...
[2(2)]-para-cyclophane-fused tetraazaporphyrins-AM1 treatment
Türker, Burhan Lemi (Informa UK Limited, 2000-01-01)
Di- and tri- [2(2)]-para-cyclophane fused metal-free tetraazaporpyrins were subjected to AM1 type semiempirical molecular orbital treatment. The calculations predict that they should be stable but endothermic structures. Some quantum chemical and physicochemical properties of them have been presented as well.

The decay constant for the strong off-shell B* --> B pi decay in the context of QCD sum rules is calculated.
POD-ROM for the Darcy-Brinkman equations with double-diffusive convection
Eroglu, Fatma G.; Kaya Merdan, Songül; Rebholz, Leo G. (Walter de Gruyter GmbH, 2019-09-01)
This paper extends proper orthogonal decomposition reduced order modeling to flows governed by double diffusive convection, which models flow driven by two potentials with different rates of diffusion. We propose a reduced model based on proper orthogonal decomposition, present a stability and convergence analyses for it, and give results for numerical tests on a benchmark problem which show it is an effective approach to model reduction in this setting.
