Data on molecular docking of tautomers and enantiomers of ATTAF-1 and ATTAF-2 selectivty to the human/fungal lanosterol-14?-demethylase.

ABSTRACT: The data have been obtained for tautomers and enantiomers of ATTAF-1 and ATTAF-2 that were developed based on antifungal standard drugs with triazole scaffold. These compounds were docked into the human and fungal lanosterol-14?-demethylase. In order to validate the data, 8 standard triazole antifungal drugs (Fluconazole, Itraconazole, Posaconazole, Ravuconazole, Albaconazole, Voriconazole, Isavuconazole and Efinaconazole) were also docked into the human and fungal lanosterol-14?-demethylase. The binding conformations of these molecules and their interactions with lanosterol-14?-demethylase may inform the development of further small molecule lanosterol-14?-demethylase inhibitors with significant selectivity toward this enzyme. The analysis has done on the basis of type of interactions (bond type and distance). The length of the Fe-N coordination bond for (R)-N2-ATTAF-1 and (S)-N1-ATTAF-2 complexes is obtained 6.36 and 4.19?Å, respectively and about 2?Å in the other tautomer and enantiomer complexes, reflecting the lower basicity of the N-4 atom in the 1,2,4-triazole ring of (R)-N2-ATTAF-1 and (S)-N1-ATTAF-2 in comparison with the N-4 atom in the 1,2,4-triazole ring in other tautomers and enantiomers and supporting higher selectivity of (R)-N2-ATTAF-1 and (S)-N1-ATTAF-2 towards the target CYP51 enzymes vs. human. Interestingly, we have investigated unfavorable interactions (donor-donor) with TRP239 and MET378 for (R)-N2-ATTAF-1 and (S)-N1-ATTAF-2, respectively. These unfavorable interactions also have been seen in case of posaconazole and isavuconazole. The data presented in this article are related to the research paper entitled "In silico prediction of ATTAF-1 and ATTAF-2 selectivity towards human/fungal lanosterol 14?-demethylase using molecular dynamic simulation and docking approaches".
