molecular docking of biaryloxy-substituted triazoles as lanosterol 14-demethylase inhibitor

Ro 09-1470 is a selective inhibitor of P-450 lanosterol C-14 demethylase of fungi.

Ro 09-1470 is a new antifungal agent that belongs to a series of compounds characterized by a tetrahydropyran skeleton with glycine and alkenyl side chains and that inhibits P-450 lanosterol C-14 demethylase (P-450(14DM)) of fungi (Y. Aoki, T. Yamazaki, M. Kondoh, Y. Sudoh, N. Nakayama, Y. Sekine, H. Shimada, and M. Arisawa, J. Antibiot. 45:160-170, 1992; S. Matsukuma, T. Ohtsuka, H. Kotaki, H....

Expression of Lanosterol 14-Demethylase (ERG11) Gene of Three-Drug Combinations in Candida albicans

Patients with impaired immunity are at particular risk of infections with Candida albicans. Antifungal drugs such as azoles commonly used for candidiasis treatment, but drug resistance is one of the most common problems for public health. The aim of this study was to evaluate the expression of lanosterol 14-demethylase (ERG11) gene for three-drug combinations in C. albicans. Disk diffusion and ...

De novo design of non-coordinating indolones as potential inhibitors for lanosterol 14-α-demethylase (CYP51).

The development of antifungal drugs that inhibit lanosterol 14-α-demethylase (CYP51) via non-covalent ligand interactions is a strategy that is gaining importance. A series of novel tetraindol-4-one derivatives with 1- and 2-(2,4-substituted phenyl) side chains were designed and synthesized based on the structure of CYP51 and fluconazole. The antifungal activities of these derivatives against e...

design and synthesis of 4-substituted azoles and prediction of their binding to 14α-demethylase using molecular docking

Synthesis and Molecular Docking Studies of 2-arylideneindan-1,3-diones Derivatives as an Inhibitor of 17β-hydroxysteroid Dehydrogenase Type 1

Due to the drawbacks of applying catalysts in the synthesis of α,β-unsaturated structure units and the importance of these materials, electrochemistry has been introduced as an efficient alternative.Therefore, herein a high-yield synthesis of 2-arylideneindan-1,3-diones is proposed. The procedure is carried out in propanol, using electrons as a green catalyst for generating propanol anion...

Amino acid variations of cytochrome P-450 lanosterol 14 alpha-demethylase (CYP51A1) from fluconazoleresistant clinical isolates of Candida albicans.

We studied six clinical isolates of Candida albicans. All six isolates showed high level resistance to fluconazole (minimum inhibitory concentrations 64 microg/ml) with varying degrees of cross-resistance to other azoles but not to amphotericin B. Neither higher dosage nor upregulation of the gene encoding the cytochrome P- 450 lanosterol 14 alpha-demethylase (CYP51A1 or P-450LDM) was responsib...
