Objectives: Molecular docking and QSAR studies of indole derivatives as antibacterial agents. Methods: In this study, we used a multiple linear regressions (MLR) approach to construct a 2D quantitative structure activity relationship of 14 reported indole derivatives. It was performed on the reported antibacterial activity data of 14 compounds based on theoretical chemical descriptors to construct statistical models that link structural properties of indole derivatives to antibacterial activity. We have also performed molecular docking studies of same compounds by using Maestro module of Schrodinger. A set the molecular descriptors like hydrophobic, geometric, electronic and topological characters were calculated to represent the structural features of compounds. The conventional antibiotics sultamicillin and ampicillin were not used in the model development since their structures are different from those of the created compounds. Biological activity data was first translated into pMIC values (i.e. –log MIC) and used as a dependent variable in QSAR investigation. Results: Compounds with high electronic energy and dipole moment were effective antibacterial agents against S. aureus, indole derivatives with lower κ 2 values were excellent antibacterial agents against MRSA standard strain, and compounds with lower R value and a high 2 χ v value were effective antibacterial agents against MRSA isolate. Conclusion: Compounds 12 and 2 showed better binding score against penicillin binding protein 2 and penicillin binding protein 2a respectively.

This study was conducted to develop inbred backcross lines (IBLs) in Indian slicing cucumber ( Cucumis sativus L.) with the gynoecious trait. The F 2 mapping population was developed using the Indian monoecious cultivar of light-green-fruited Pusa Uday as the recurrent parent and the American gynoecious pickling line G421 as a donor. Two markers, SSR13251 and SSR15516, were found to be closely linked to the F locus at 1.5 and 4.5 cM, respectively, by marker analysis of F 2 individuals. The amplifi ed product of 430 bp generated using a SCAR marker ( CsACS1G ) in gynoecious ( MMFF ) and sub-gynoecious ( MMFf ) plants of the F 2 population confirmed the dominance of F alleles. The IBLs were developed by backcrossing Pusa Uday with BC 1 and BC 2 progenies followed by foreground and background selection of plants displaying the gynoecious habit in the background of Indian slicing cucumber. These IBLs could be utilized for the development of hybrids with higher yield, earliness, and quality.
